Diabetes Mellitus is affecting people of all age groups worldwide. Many synthetic medicines available for type 2 diabetes mellitus in the market. However, there is a strong requirement for the development of better anti-diabetes compounds sourced especially from natural sources like medicinal plants. The extracts from the leaves of neem (Azadirachta indica) is traditionally known to have anti-diabetes properties. Therefore, there is an increased interest to identify potential compounds identified from neem leaf extracts showing predicted binding property with the known diabetes mellitus type 2 protein enzyme target phosphoenol-pyruvate carboxykinase(PEPCK). The structure data for compounds found in the leaf extract of neem was screened against PEPCK using molecular docking simulation and screening techniques. Results show that the compound 3-Deacetyl-3-cinnamoyl-azadirachtin possesses best binding properties with PEPCK. This observation finds application for further consideration in in vitro and in vivo validation.
