Exploring 8-benzyl pteridine-6,7-diones as inhibitors of glutamate racemase (MurI) in Gram-positive bacteria
摘要:
A successful scaffold-hopping approach gave a novel series of inhibitors of bacterial glutamate racemase (MurI). Early SAR studies of the 8-benzyl pteridine-6,7-diones led to compounds with micromolar enzyme potency and antibacterial activity. (C) 2008 Elsevier Ltd. All rights reserved.

A series of 2-substituted-4,6-diaminipyrimidine derivatives were synthesized and evaluated for their dihydrofolate reductase (DHFR) inhibitory activity. Saturation transfer difference (STD) 1H-NMR experiments were used to probe the binding characteristics of the compounds with human DHFR enzyme. The most potent molecules, 12 and 15, in enzyme assay study showed the best results in STD experiments indicating their intimate interaction with the receptor. The docking studies were followed to explain the structural basis for the observed interaction between the ligands and DHFR. All the compounds were also assayed in vitro for their growth inhibitory activity on MCF-7, HepG2, SKHep1, and Hela tumor cell lines. Compounds 16, 17, and 22 demonstrated the most potent in vitro anti-proliferative activity among the others.
