As a privileged scaffold, the quinazoline ring is widely used in the development of EGFR inhibitors, while few quinazoline-based MET inhibitors are reported. In our ongoing efforts to develop new MET-targeted anticancer drug candidates, a series of quinaz

Accurate prediction of absolute protein-ligand binding free energy could considerably enhance the success rate of structure-based drug design but is extremely challenging and time-consuming. Free energy perturbation (FEP) has been proven reliable but is limited to prediction of relative binding free energies of similar ligands (with only minor structural differences) in binding with a same drug target in practical drug design applications. Herein, a Gaussian algorithm-enhanced FEP (GA-FEP) protocol has been developed to enhance the FEP simulation performance, enabling to efficiently carry out the FEP simulations on vanishing the whole ligand and, thus, predict the absolute binding free energies (ABFEs). Using the GA-FEP protocol, the FEP simulations for the ABFE calculation (denoted as GA-FEP/ABFE) can achieve a satisfactory accuracy for both structurally similar and diverse ligands in a dataset of more than 100 receptor-ligand systems. Further, our GA-FEP/ABFE-guided lead optimization against phosphodiesterase-10 led to the discovery of a subnanomolar inhibitor (IC50 = 0.87 nM, ~2000-fold improvement in potency) with cocrystal confirmation.

A highly efficient one pot conversion of 4-methoxy-3-benzyloxy-6-nitro benzoate to 6-benzoyloxy-7-methoxy quinazoline-4-one using Fe/acetic acid and formamidine acetate followed by debenzylation of 4-(3-chloro-4-flurophenylamino)-6-benzoyloxy-7-methoxy quinazoline using methanesulfonic acid in chloroform is described. Additionally the desmethyl impurity formation is controlled using oxalyl chloride and DIPEA.
