Design and synthesis of BACE-1 inhibitors utilizing a tertiary hydroxyl motif as the transition state mimic
摘要:
Two series of drug-like BACE-1 inhibitors with a shielded tertiary hydroxyl as transition state isostere have been synthesized. The most potent inhibitor exhibited a BACE-1 IC50 value of 0.23 mu M. (C) 2009 Elsevier Ltd. All rights reserved.
A new generation of HIV-1 protease inhibitors encompassing a tertiary-alcohol-based transition-state mimic has been developed. By elongation of the core structure of recently reported inhibitors with two carbon atoms and by varying the P1' group of the compounds, efficient inhibitors were obtained with Ki down to 2.3 nM and EC50 down to 0.17 microM. Two inhibitor-enzyme X-ray structures are reported
