Main Article Content
Diabetes mellitus is a chronic metabolic disease, which is characterized by elevated blood glucose levels, caused by a deficiency in insulin secretion from the β pancreatic’s cells or the operability of insulin. The protein tyrosine phosphatase 1B (PTP1B) catalyzes to removing the phosphate group from the insulin receptor's phosphotyrosine, then reducing insulin’s effects. Therefore, inhibiting this enzyme is an effective method to treat diabetes mellitus. Momordica charantia is effective in the treatment of diabetes mellitus. In this study, we evaluated the inhibitory effects of PTP1B enzyme of Momordica charantia’s compounds by using molecular docking method. Based on the previous publication of Momordica charantia, we have collected 57 compounds. The results showed that 3 compounds have PTP1B inhibitory effect stronger than the positive control including Luteolin-7-O-glycoside, apigenin-7-O-glycoside and δ-cadinene. Analysis Lipinski Rule of Five showed that Luteolin-7-O-glycoside and δ-cadinene have drug-likeness properties. Moreover, predict ADMET showed that these two compounds have good intestinal absorption, not metabolized in the liver, excretion by the kidney and low toxicity. Conclusion: Our findings suggested that luteolin-7-O-glycoside, δ-cadinene may be potential natural product compounds for diabetes treatment type 2.
