Discovery of a potent and highly β1 specific proteasome inhibitor from a focused library of urea-containing peptide vinyl sulfones and peptide epoxyketones
BACE-1已成为未来阿尔茨海默氏症治疗中最具特征的靶标之一。根据成功鉴定的HIV-1蛋白酶的掩蔽抑制剂,我们预见到含有叔醇的过渡态模拟结构也将作为BACE-1抑制剂值得评估。通过合成路线使用环氧醇衍生物作为关键中间体制备了十二种新型抑制剂。最佳合成的叔羟基抑制剂的BACE-1 IC 50值为0.38μM。

A family of new chiral zwitterionic phosphorus‐containing heterocycles (zPHC) have been derived from methylene‐bridged bis(imidazolines). These structures were unambiguously determined, including single‐crystal XRD analysis for two compounds. The stability, acid/base and electronic properties of these dipolar phosphorusheterocycles were subsequently investigated. zPHCs can be successfully employed
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.
