- W4223641711 abstract "A novel strategy for lead identification that we have dubbed the Pocket-to-Lead strategy is demonstrated using HIV-1 protease as a model target. Sometimes, it is difficult to obtain hit compounds because of the difficulties in satisfying the complex pharmacophoric features. In this study, a virtual fragment hit which does not match all of the pharmacophore features but has key interactions and vectors that could grow into remaining pharmacophore features was optimized in silico. The designed compound 9 demonstrated weak but evident inhibitory activity (IC50 = 54 μM), and the design concept was proven by the co-crystal structure. Then, structure-based drug design promptly gave compound 14 (IC50 = 0.0071 μM, EC50 = 0.86 μM), an almost 10,000-fold improvement in activity from 9. The structure of the designed molecules proved to be novel with high synthetic feasibility, indicating the usefulness of this strategy to tackle tough targets with complex pharmacophore." @default.
