Toxicity prediction and analysis of flavonoid apigenin as a histone deacetylase inhibitor: an in-silico approach.

Occurrence of cancer is driving up on a global scale that exerts greater implications on the physical, psychological and economic stability of the human population. In the present context, numerous research studies are being conducted to explore and discover the drug molecule as an anticancer agent. Diverse scales of flavonoids entail the human diet, and they displayed prospective curative effects against an array of ailments. Among different categories of flavonoids, apigenin a trihydroxy flavone has been proven to have various pharmacological effects. Molecular docking is a key tool in structural molecular biology and computer assisted drug design. In this study, HDAC inhibitory action of apigenin and its probable toxicity was assessed by docking study using Auto dock platform. Molecular dynamics simulation was done by using iMODS server for elucidating the stability of the receptor-ligand complex. Toxicity predictions were evaluated by using tools such as CarcinoPred for carcinogenicity study, pkCSM for ADMET analysis, ProTox-II for rodent oral toxicity, lazar for estimating mutagenicity, BOILED Egg plot analysis for examining the gastrointestinal absorption and blood brain permeability, PASS prediction to identify the various biological functions and DruLiTo program to compute the drug likeness property.
