Some of the medicinal preparations / products based on Andrographis paniculata Nees

Andrographis paniculata Nees (Acanthaceae), the King of Bitters is an erect annual herb extremely bitter in taste in each and every part of the plant body [more info].  Since ancient times, A. paniculata is used as a wonder drug in many traditional systems of medicine in many countries for multiple clinical applications. The plant extract exhibits antityphoid , antifungal,  antihepatotoxic, antibiotic, antimalarial, antihepatitic, antithrombogenic, antiinflammatory, antisnakevenom, and antipyretic properties to mention a few, besides its general use as an immunostimulant agent (see Pharmacology).  Andrographolide is the major medicinally active substance of the plant which is a bicyclic diterpenoid lactone [details].

1: Phytomedicine. 2006 May;13(5):318-23. Epub 2005 Sep 16. The effect of Kan Jang extract on the pharmacokinetics and pharmacodynamics of warfarin in rats. Hovhannisyan AS, Abrahamyan H, Gabrielyan ES, Panossian AG.

Significant pharmacokinetic/pharmacodynamic interactions between various herbal products and warfarin have recently been reported. The aim of this study was to determine whether concomitant treatment of rats with Kan Jang (a standardized fixed combination of extracts from Andrographis paniculata and Eleutherococcus senticosus) and warfarin would lead to an alteration in the pharmacological effects of warfarin. Each day for 5 days a group of animals was treated orally with an aqueous solution of Kan Jang at a dose of 17 mg/kg of the active principle andrographolide (a daily dose some 17-fold higher than that recommended for humans): the control group received similar treatment with appropriate volumes of water only. Sixty minutes after the final daily administration of Kan Jang or water, an aqueous solution of warfarin (0.2 mg/ml) was given to each animal at a dose of 2 mg/kg. From each group, 6 animals were sacrificed at 0, 2, 4, 6, 8, 12, 24, 30 and 48 h after warfarin administration and blood samples taken. The concentration of warfarin in blood plasma was measured by capillary electrophoresis using 50 mM borate buffer (pH 9.3) as mobile phase with simultaneous detection of warfarin at 208.1 and 307.5 nm. Prothrombin time in blood plasma was measured using thromboplastin reagent. The concomitant application of Kan Jang and warfarin did not produce significant effects on the pharmacokinetics of warfarin, and practically no effect on its pharmacodynamics.

2: Phytomedicine. 2005 Jun;12(6-7):403-9. A phase I clinical study of Andrographis paniculata fixed combination Kan Jang versus ginseng and valerian on the semen quality of healthy male subjects. Mkrtchyan A, Panosyan V, Panossian A, Wikman G, Wagner H.

The safety of different doses of Kan Jang--a fixed combination of Andrographis paniculata special extract (SHA-10) and Acanthopanax senticosus--compared to two extensively used medicinal plants, Valeriana officinalis and Panax ginseng in the form of standardized extracts, has been examined. A phase I clinical study was designed to evaluate the effect on semen quality of healthy males in terms of spermatogenesis and quality of semen. The results of the study revealed no significant negative effect of Kan Jang on male semen quality and fertility, but rather a positive trend with respect to the number of spermatozoids in the whole ejaculate, the percentage of active (normokinetic) forms of spermatozoids, and fertility indexes, together with a decrease in the percentage of inactive (diskinetic) forms of spermatozoids. In the group receiving ginseng, no significant negative effects on the fertility parameters were revealed and there was a clear decrease in the percentage of diskinetic forms of spermatozoids. Subjects receiving valerian showed a temporary increase in the percentage of normokinetic spermatozoids and a decrease in diskinetic forms, but these changes had no effect on fertility indices. The results indicate that Kan Jang, ginseng and valerian are safe with respect to effects on human male sterility when administered at dose levels corresponding to approximately 3 times the human daily dose.

3: J Herb Pharmacother. 2003;3(1):77-93. A randomized, controlled study of Kan Jang versus amantadine in the treatment of influenza in Volgograd. Kulichenko LL, Kireyeva LV, Malyshkina EN, Wikman G.

Two randomized, parallel-group clinical studies with a verum and a control group were performed to investigate the effect of a standardized extract (SHA-10) of Andrographis panaiculata (N.) fixed combination Kan Jang in the treatment of diagnosed influenza viral infection. The pilot study was performed on 540 patients with 71 Kan Jang-treated patients with the second phase conducted enrolling 66 patients. The differences in the duration of sick leave and frequency of post-influenza complications indicate that the Kan Jang phytopreparation not only contributes to quicker recovery, but also reduces the risk of post-influenza complications. Kan Jang was well tolerated by patients. PMID: 15277072 [PubMed]

4: Phytother Res. 2004 Jan;18(1):47-53. Comparative controlled study of Andrographis paniculata fixed combination, Kan Jang and an Echinacea preparation as adjuvant, in the treatment of uncomplicated respiratory disease in children. Spasov AA, Ostrovskij OV, Chernikov MV, Wikman G.

A three-arm study comparing the efficacy of Kan Jang, a fixed herbal combination containing standardized Andrographis paniculata (N.) SHA-10 extract, with Immunal, a preparation containing Echinacea purpurea (L.) extract, in uncomplicated common colds was carried out in 130 children aged between 4 and 11 years over a period of 10 days. The study was designed as an adjuvant treatment of Kan Jang and Immunal with a standard treatment. The patients were assigned to one of the three groups. In control group C; 39 patients received only standard treatment. Kan Jang and Immunal were used as an adjuvant to this therapy in the other two groups. Adjuvant group A; 53 patients treated with Kan Jang tablets concomitant to standard treatment, and adjuvant control group B; 41 patients treated with concomitant Immunal. It was found that the adjuvant treatment with Kan Jang, was significantly more effective than Immunal, when started at an early stage of uncomplicated common colds. The symptoms of the disease were less severe in the Kan Jang group. The effect of Kan Jang was particularly pronounced in two objective parameters, amount of nasal secretion g/day and nasal congestion. Kan Jang also accelerated the recovery time, whereas Immunal did not show the same efficacy. The use of standard medication was significantly less in the Kan Jang adjuvant group than in either the Immunal or standard treatment group. Kan Jang treatment was well tolerated and no side effects or adverse reactions were reported. Copyright 2004 John Wiley & Sons, Ltd. PMID: 14750201 [PubMed - indexed for MEDLINE]

5: Phytomedicine. 2002 Oct;9(7):598-605. Effect of andrographolide and Kan Jang--fixed combination of extract SHA-10 and extract SHE-3--on proliferation of human lymphocytes, production of cytokines and immune activation markers in the whole blood cells culture. Panossian A, Davtyan T, Gukassyan N, Gukasova G, Mamikonyan G, Gabrielian E, Wikman G.

The immunomodulatory properties of a diterpene lactone andrographolide and Kan Jang--a standardized fixed combination of Andrographis paniculata extract SHA-10 and Eleutherococcus senticosus extract SHE-3 were investigated. Their role on spontaneous and phytohemagglutinin (PHA)-induced proliferation of human peripheral blood lymphocytes (PBL) and on production of interferon-gamma (INF-gamma) and tumor necrosis factor-alpha (TNF-alpha) were determined in vitro. Proliferation of PBL induced by PHA was enhanced by co stimulation with andrographolide and Kan Jang. At the same time andrographolide and Kan Jang inhibit spontaneous proliferation of PBL in vitro. These preparations also have effect on the formation of INF-gamma, TNF-alpha and some immune activation markers such as neopterin (Neo), beta-2-microglobulin (beta2MG), and soluble receptor for interleukin-2 (sIL-2R or sCD25) in blood cells culture. Andrographolide and Kan Jang stimulate the INF-gamma, Neopterin and beta2MG formation, but do not have any significant effect on the production of INF-gamma and Neopterin in PHA stimulated blood cells. An opposite effect on these immune makers was observed in the PHA-stimulated blood cells: both andrographolide and Kan Jang increase the formation of TNF-alpha and beta2MG in cultivated whole blood cells. Thus, andrographolide and Kan Jang can have an in vitro effect on the activation and proliferation of immunocompetent cells as well on the production of key cytokines and immune activation markers. The results show an overall higher effect of the fixed combination as compared with the equivalent amount of the pure substance andrographolide. The data are consistent with results from clinical studies of Kan Jang and contributed to a better understanding of these results. PMID: 12487323 [PubMed - indexed for MEDLINE]

6: Phytomedicine. 2002 Oct;9(7):589-97. A double blind, placebo-controlled study of Andrographis paniculata fixed combination Kan Jang in the treatment of acute upper respiratory tract infections including sinusitis. Gabrielian ES, Shukarian AK, Goukasova GI, Chandanian GL, Panossian AG, Wikman G, Wagner H. Erebuni

A double blind, placebo-controlled, parallel-group clinical study was carried out to evaluate the effect of an Andrographis paniculata (N.) extract SHA-10 fixed combination, Kan Jang, in the treatment of acute upper respiratory tract infections, including sinusitis. Ninety-five individuals in the treatment group and 90 individuals in the placebo group completed the study according to the protocol. The medication was taken for 5 days. Temperature, headache, muscle aches, throat symptoms, cough, nasal symptoms, general malaise and eye symptoms were taken as outcome measures with given scores. The total score analysis showed a highly significant improvement in the verum group versus the placebo. This result applied to the group as a whole and to the sinusitis subgroups. The individual symptoms of headache and nasal and throat symptoms together with general malaise showed the most significant improvement while cough and eye symptoms did not differ significantly between the groups. Temperature was moderately reduced in the verum group. It can be concluded that Kan Jang has a positive effect in the treatment of acute upper respiratory tract infections and also relieves the inflammatory symptoms of sinusitis. The study drug was well tolerated. PMID: 12487322 [PubMed - indexed for MEDLINE]

7: Mol Cells. 2002 Feb 28;13(1):21-7. Production of monoclonal antibodies and immunohistochemical studies of brain myo-inositol monophosphate phosphatase. Bahn JH, Kim AY, Jang SH, Lee BR, Ahn JY, Joo HM, Kan TC, Won MH, Kwon HY, Kang JH, Kwon OS, Kim HB, Cho SW, Lee KS, Park J, Choi SY.

Five monoclonal antibodies that recognize porcine brain myo-inositol monophosphate phosphatase (IMPase) have been selected and designated as mAb IMPP 9, IMPP 10, IMPP 11, IMPP 15, and IMPP 17. These antibodies recognize different epitopes of the enzyme and one of these inhibited the enzyme activity. When the total proteins of the porcine brain homogenate separated by SDS-PAGE were probed with monoclonal antibodies, a single reactive protein band of 29 kDa, co-migrating with the purified porcine brain IMPase, was detected. Using the anti-IMPase antibodies as probes, the cross reactivities of the brain IMPase from human and other mammalian tissues, as well as from avian sources, were investigated. Among the human and animal tissues tested, the immunoreactive bands on Western blots appeared to have the same molecular mass of 29 kDa. In addition, there was IMPase immunoreactivity in the various neuronal populations in the rat brain. These results indicate that mammalian brains contain only one major type of immunologically similar IMPase, although some properties of the enzymes that were previously reported differ from each another. The first demonstration of the IMPase localization in the brain may also provide useful data for future investigations on the function of this enzyme in relation to various neurological diseases.

8: Biochem Biophys Res Commun. 2001 May 18;283(4):791-7. Evidence that the intracellular domain of FGF receptor 2IIIb affects contact of the ectodomain with two FGF7 ligands. Uematsu F, Jang JH, Kan M, Wang F, Luo Y, McKeehan WL.

Models of the oligomeric FGF signaling complex, including those derived from crystal structures, vary in stoichiometry and arrangement of the three subunits comprised of heparin/heparan sulfate chains, FGFR tyrosine kinase and activating FGF. Here, using covalent affinity crosslinking of radiolabeled FGF7 to binary complexes of FGFR2IIIb and heparin, we show that two molecules of FGF7 contact each FGFR2IIIb. This supports models that propose a dimeric complex of two units with stoichiometry 1 FGF:1 FGFR in which each FGF contacts both FGFR. The bivalent FGF7 contact was dependent on the full-length amino terminus of FGF7alpha and the intracellular domain of FGFR2IIIb extending through the juxtamembrane domain and the beta1 and beta2 strands of the kinase which is required for ATP binding. We propose that the differences in crosslinking report differences in relationships among subunits in the ectodomain of the complex that are affected by the amino terminus of FGF and the FGFR intracellular domain. From this, we suggest the corollary that conformational relationships among subunits in the ectodomain are transmitted to the intracellular and ATP binding domains during activation of the complex.

9: Phytomedicine. 2000 Oct;7(5):351-64. Pharmacokinetic and oral bioavailability of andrographolide from Andrographis paniculata fixed combination Kan Jang in rats and human. Panossian A, Hovhannisyan A, Mamikonyan G, Abrahamian H, Hambardzumyan E, Gabrielian E, Goukasova G, Wikman G, Wagner H.

Validated analytical methods (HPLC, CE and GC-MS) for determining the amount of andrographolide (AND) in the blood plasma of rats and human volunteers following the oral administration of Andrographis paniculata extract (APE) and Andrographis paniculata fixed combination Kan Jang tablets were developed and used for the pharmacokinetic study. Andrographolide was quickly and almost completely absorbed into the blood following the oral administration of APE at a dose of 20 mg/kg body wt. in rats. Its bio-availability, however, decreased four-fold when a 10-times-higher dose was used. Since a large part (55 %) of AND is bound to plasma proteins and only a limited amount can enter the cells, the pharmacokinetics of AND are described well by a one-compartment model. Renal excretion is not the main route for eliminating AND. It is most likely intensely and dose dependently metabolized. Following the oral administration of four Kan Jang tablets (a single therapeutic dose, equal to 20 mg of AND) to humans, maximum plasma levels of approximately 393 ng/ml (approx. 1.12 microM) were reached after 1.5-2 hours, as quantified using a UV diode-array detection method. Half-life and mean residence times were 6.6 and 10.0 hours, respectively. AND pharmacokinetics in humans are explained well by an open two-compartment model. The calculated steady state plasma concentration of AND for multiple doses of Kan Jang (after the normal therapeutic dose regimen, 3 x 4 tablets/day, about 1 mg AND/kg body wt./day) was approximately 660 ng/ml (approx. 1.9 microM), enough to reveal any anti-PAF effect, particularly after drug uptake when the concentration of AND in blood is about 1342 ng/ml (approx. 3.8 microM, while for anti-PAF effect EC50 - 5 microM).

10: Phytomedicine. 2000 Oct;7(5):341-50. Double-blind, placebo-controlled pilot and phase III study of activity of standardized Andrographis paniculata Herba Nees extract fixed combination (Kan jang) in the treatment of uncomplicated upper-respiratory tract infection. Melchior J, Spasov AA, Ostrovskij OV, Bulanov AE, Wikman G. Hallehalsan

Two randomized double-blind, placebo-controlled parallel group clinical trials were performed to investigate the effect of a standardized extract (SHA-10) of Andrographis paniculata fixed combination (Kan jang) in the treatment of uncomplicated upper-respiratory tract infections. 46 patients in the pilot study and 179 patients in the phase III study completed the study according to the protocol. Medication was taken three times daily for a minimum of 3 days and a maximum of 8 days for the pilot study, and for exactly three days in the phase III study. The primary outcome measures in the patients self-evaluation were: related to pain in the muscle, cough, throat symptoms, headache, nasal symptoms and eye symptoms and temperature. The physician's fixed score diagnosis was based mainly on sign/symptoms: ears, nose, oral cavity, lymph glands-tonsils and eyes. The total symptom score showed a tendency toward improvement in the pilot study (p = 0,08), while both the total symptom score and total diagnosis score showed highly significant improvement (p < or = 0.0006 resp. 0.003) in the verum group as compared with the placebo. In both studies throat symptoms/signs, were found to show the most significant improvement.

11: Biochem Biophys Res Commun. 2000 Jun 16;272(3):830-6. Ligand binding properties of binary complexes of heparin and immunoglobulin-like modules of FGF receptor 2. Uematsu F, Kan M, Wang F, Jang JH, Luo Y, McKeehan WL.

Epithelial cells, which express FGFR2IIIb, bind and respond to FGF-1, FGF-7 and FGF-10, but not FGF-2. Stromal cells, which bind and respond to FGF-1 and FGF-2, but not FGF-7 and FGF-10, express FGFR2IIIc or FGFR1IIIc. Here we show that when both isolated FGFR2betaIIIb and FGFR2betaIIIc or their common Ig module II are allowed to affinity select heparin from a mixture, the resultant binary complexes bound FGF-1, FGF-2, and FGF-7 with nearly equal affinity. In addition, FGF-2 and FGF-7 bound to both heparin-Ig module IIIb and IIIc complexes, but FGF-1 bound to neither Ig module III. The results show that in isolation both Ig modules II and III of FGFR2 can interact with heparin and that each exhibits a binding site for FGF. We suggest that the specificity of FGFR2IIIb and FGFR2IIIc is dependent on the cell membrane environment and heparin/heparan sulfate. Ig modules II and III cooperate both within monomers and across dimers with cellular heparan sulfates to confer cell type-dependent specificity of the FGFR complex for FGF.

12: Phytomedicine. 1999 Jul;6(3):157-61. Effect of Andrographis paniculata extract on progesterone in blood plasma of pregnant rats. Panossian A, Kochikian A, Gabrielian E, Muradian R, Stepanian H, Arsenian F, Wagner H.

The effect of the powdered extract of Andrographis paniculata leaves (APE), an active principle of Kan Jang tablets [standardized for content of andrographolide (4.6%) and 14-deoxo-andrographolide (2.3%) content (total andrographolids--6.9%)] on blood progesterone content in rats was studied. Peroral administration of APE during the first 19 days of pregnancy in doses of 200, 600, and 2000 mg/kg (i.e. doses 30, 90, and 300 fold higher than its daily therapeutic dose in humans) does not exhibit any effect on the elevated level of progesterone in the blood plasma of rats. Let us assume then that in therapeutic dose, Andrographis paniculata extract cannot induce progesterone-mediated termination of pregnancy. PMID: 10439479 [PubMed - indexed for MEDLINE]

13: Biochemistry. 1998 Nov 24;37(47):16506-15. The glycine box: a determinant of specificity for fibroblast growth factor. Luo Y, Lu W, Mohamedali KA, Jang JH, Jones RB, Gabriel JL, Kan M, McKeehan WL.

Acidic fibroblast growth factor (FGF-1), keratinocyte growth factor (FGF-7), and FGF-10 are homologues with distinct specificity. In the presence of heparin, FGF-1 binds and activates in vitro all FGFR subtypes, while FGF-7 exhibits absolute specificity for the IIIb splice variant of FGFR2. FGF-10 exhibits a similar specificity but also binds the FGFR1IIIb isoform. Neither FGF-7 nor FGF-10 will bind to IIIc isoforms of FGFR. Molecular models of FGF, heparin, and the FGFR ectodomain suggested that sequences between beta-strands 10 and 12 of FGF may be important for the interaction of FGF with the heparin-FGFR ectodomain duplex. Site-directed mutants of FGF-7 and FGF-10 were prepared to test whether this domain might underlie failure of FGF-7 and FGF-10 to bind to the FGFRIIIc isoforms. Constructions with substitution of FGF-1 sequences spanning the entire C-terminus encoded in exon 3 or only C-terminal sequences spanning beta-strands 10 through 12 conferred ability on FGF-7 to bind to and activate FGFRIIIc without a significant loss in binding to or activation of FGFR2IIIb. A series of twelve different substitutions of shorter segments of FGF-1 sequences into the C-terminal portion of FGF-7 or FGF-10 revealed that substitution of GSCKRG for GIPVRG or the tri-peptide sequence KKN for NQK just N-terminal to it conferred dual activities on both the FGF-7 and FGF-10 backbones. The results suggest that the combined sequence domain, which we call the FGF glycine box (G-box), is a major determinant for the specificity of the binding of FGF to heparan sulfate-FGFR duplexes.

14: In Vitro Cell Dev Biol Anim. 1997 Nov-Dec;33(10):819-24. Heparan sulfate is required for interaction and activation of the epithelial cell fibroblast growth factor receptor-2IIIb with stromal-derived fibroblast growth factor-7. Jang JH, Wang F, Kan M.

Fibroblast growth factor-7 (FGF-7) and a specific splice variant of the FGF tyrosine kinase receptor family (FGFR2IIIb) constitute a paracrine signaling system from stroma to epithelium. Different effects of the manipulation of cellular heparan sulfates and heparin on activities of FGF-7 relative to FGF-1 in epithelial cells suggest that pericellular heparan sulfates may regulate the activity of FGF-7 by a different mechanism than other FGFs. In this report, we employ the heparan sulfate-binding protein, protamine sulfate, to reversibly block cellular heparan sulfates. Protamine sulfate, which does not bind significantly to FGF-7 or FGFR2IIIb, inhibited FGF-7 activities, but not those of epidermal growth factor. The inhibition was overcome by increasing the concentrations of FGF-7 or heparin. Heparin was essential for binding of FGF-7 to recombinant FGFR2IIIb expressed in insect cells or FGFR2IIIb purified away from cell products. These results suggest that, similar to other FGF polypeptides, heparan sulfate within the pericellular matrix is required for activity of FGF-7. Differences in response to heparin and alterations in the BULK heparan sulfate content of cells likely reflect FGF-specific differences in the cellular repertoire of multivalent heparan sulfate chains required for assembly and activation of the FGF signal transduction complex.

16: J Biol Chem. 1997 Sep 19;272(38):23887-95. A homeo-interaction sequence in the ectodomain of the fibroblast growth factor receptor. Wang F, Kan M, McKeehan K, Jang JH, Feng S, McKeehan WL.

Interaction of fibroblast growth factor receptors (FGFR) sufficient for a trans-phosphorylation event in which one intracellular domain is substrate for the other is essential for signal transduction. By analysis of the direct interaction of recombinant constructions co-expressed in baculoviral-infected insect cells, we identified a 17-amino acid sequence that is required for the stable interaction between ectodomains of FGFR. The sequence 160ERSPHRPILQAGLPANK176 (Glu160-Lys176) connects immunoglobulin modules II and III. In insect cells, the interaction between Glu160-Lys176 domains occurs independently of intact heparin or FGF binding domains. The sequence is not required for the binding of heparin or FGF-1, but is essential for mitogenic activity of the FGFR kinase in mammalian cells. The results support a model in which the homeo-interaction between Glu160-Lys176 in the ectodomain contributes to the interaction between intracellular domains in mammalian cell membranes (Kan, M., Wang, F., Kan, M., To, B., Gabriel, J. L., and McKeehan, W. L. (1996) J. Biol. Chem. 271, 26143-26148). We propose that the Glu160-Lys176 domain plays a pivotal role in restriction of the interaction between kinases by pericellular matrix heparan sulfate proteoglycan and divalent cations. Restrictions are overcome by FGF or constitutively by diverse gain of function mutations which cause skeletal and craniofacial abnormalities.
