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。
therapy. In accordance with the successful identification of masked inhibitors of HIV-1 protease, we envisioned that tert-alcohol containing transition-state mimicking structures would also be worthwhile evaluating as BACE-1 inhibitors. Twelve novel inhibitors were prepared via synthetic routes using epoxyalcohol derivates as key intermediates. The best synthesized tert-hydroxy inhibitor exhibited a BACE-1

Design and synthesis of BACE-1 inhibitors utilizing a tertiary hydroxyl motif as the transition state mimic
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 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

Syringolins, a class of natural products, potently and selectively inhibit the proteasome and show promising antitumour activity. To gain insight in the mode of action of syringolins, the ureido structural element present in syringolins is incorporated in oligopeptide vinyl sulfones and peptide epoxyketones yielding a focused library of potent new proteasome inhibitors. The distance of the ureido linkage with respect to the electrophilic trap strongly influences subunit selectivity within the proteasome. Compounds 13 and 15 are β5 selective and their potency exceeds that of syringolin A. In contrast, 5 may well be the most potent β1 selective compound active in living cells reported to date.
