Abstract

Quinazolinones are bicyclic fused heterocyclics that have been shown cytotoxic effects through different mechanisms inparticular thyrozin kinase enzyme inhibition. Based on this, a series of quinazolinone derivatives were subjected to a quantitative structure activity relationship (QSAR) analysis, by using statistical tool, such as principal components analysis (PCA) and genetic algorithm (G.A). It was shown that GA_PLS is reliable to predict activities of new design compounds. Besides, the compounds were docked into the active site of the protein thyrozin kinase (PDB entry code:1M17) to identify the binding interactions. Among the thirty two studied compounds, five compounds showed convenient inhibitory effect. The most active compound of the studied derivatives, Q19, had a ΔGbind of -9.52kcal/mol © All Rights Reserved.
