Introduction: The purpose of this study is to find potential inhibitors of leptin as a proinflammatory adipokine and alpha glucosidase as an enzyme that mediate hyperglycaemia; to alter the chronic complications of obesity from herbal Acalypha indica (Ai). This study was conducted using in silico molecular docking to evaluate the Ai compounds interaction with leptin and alpha glucosidase. The in vitro assay to alpha glucosidase was done to explore antihyperglycemic effect of Ai, as hyperglycaemia is the key process of chronic complication of obesity. Material and Methods: Protein target were leptin and alpha glucosidase; compounds from Ai plant were repundusinic, mauritanin, hesperetin, acaindinin, and glucogalin in pdb format. Molecular docking using autodock vinna. In vitro assay of Ai antihyperglycemic activity was done to alpha glucosidase and was define as IC50 level. Result: The results from the docking analysis demonstrated that compounds from Ai roots contain antihyperglycemic-antiobesity activity which acted by inhibiting leptin and alpha glucosidase receptors. Repundusininc and mauritanin compounds contain hydrogen bond with the greatest leptin enhancer activity on Ser9, Thr35, Glu8, Ser9, Thr25, Gln111, Lys211, Leu7 for repundisinic and Glu8, Thr25, Gly112 and Leu7 for mauritanin. Hesperetin, acaindinin and glucogallin were the most identical compounds with similar affinity binding value to alpha glucosidase. Ai roots was already proven as anti-hyperglycemic-antiobesity which was further confirmed by in vitro assay to alpha glucosidase (IC50 19,429 μg/ml.). Conclusion: The results demonstrated that Ai have anti hyperglycaemic-antiobesity effects and was found to be potentially as antihyperglycemic by in vitro assay to alpha glucosidase.

Aim: The aim of this study is to finding inhibitor potential from several compounds in gambir plant by using in vitro MTT assay and study interaction with molecular docking. The interaction of amino acids on the binding site with substances in the gambir plant was analyzed to determine its potential as a herbal-based therapy candidate for pulmonary fibrosis. Material and Methods: Protein target using TGFβ1 and NF-κB and compounds from gambir plant ((+)-Catechin. Epigallocatechin gallate, (+)-Epicatechin, Gambiriin A1, Gambiriin A2, Gambiriin B1, Gambiriin B2, Gambiriin C, Procyanidin B1, Procyanidin B3). Result: The results from docking analysis observed that compounds from gambir fruit contain anti-fibrotic activity which act by inhibiting DNA transcription of NF-κB and TGF-β1receptors. The compound Procyanidin B3, an essential amino acid, contains a hydrogen bond with the greatest NF-κB inhibitory activity on Gly214 and Lys337. Compounds from Uncaria gambir (Hunter) Roxb. can be an inhibitor to TGFβ1, all the compounds are on the active site of TGFβ1, and use native ligand which is an inhibitor of TGFβ1 (Naphtyridine). The positive compound catechin has the highest inhibitory activity. Gambiriin B1 and Gambiriin A2 are the most identical compounds with similar affinity binding value. Uncaria gambir (Hunter) Roxb. is already a proven antifibrotic which is further confirmed by (IC50: 19,255 {\textpm} 1.08 μg/ml, p \< 0.05) in A549 cell line. Conclusion: The results demonstrated that Gambiriin have cytotoxic effects and was found potentially as anti-fibrotic by MTT assay and in silico evaluation.
