  Further characterization of a putative serine protease contributing to the γ-secretase cleavage of β-amyloid precursor protein

  摘要：

  The 3-alkoxy-7-amino-4-chloro-isocoumarins JLK-6 and JLK-2 have been shown to markedly reduce the production of Amyloid beta-peptide (A beta) by Amyloid-beta Precursor Protein (APP) expressing HEK293 cells by affecting the gamma-secretase cleavage of APP, with no effect on the cleavage of the Notch receptor. This suggested that these compounds do not directly inhibit the presenilin-dependent gamma-secretase complex but more likely interfere with an upstream target involved in gamma-secretase-associated pathway. The mechanism of action of these compounds is unknown and there are high fundamental and therapeutical interests to unravel their target. Isocoumarin compounds were previously shown to behave as potent mechanism-based irreversible inhibitors of serine proteases, suggesting that the JLK-directed target could belong to such enzyme family. To get further insight into structure-activity relationships and to develop more potent isocoumarin derivatives, we have synthesized and evaluated a series of isocoumarin analogues with modifications at positions 3, 4 and 7. In particular, the 7-amino group was substituted with either acyl, urethane, alkyl or aryl groups, which could represent additional interaction sites. Altogether, the results highlighted the essential integrity of the 3-alkoxy-7-amino-4-chloro-isocoumarin scaffold for A beta-lowering activity and supported the involvement of a seri ne protease, or may be more generally, a serine hydrolase. The newly reported 7-N-alkyl series produced the most active compounds with an IC50 between 10 and 30 mu M. Finally, we also explored peptide boronates, a series of reversible serine protease inhibitors, previously shown to also lower cellular A beta production. The presented data suggested they could act on the same target or interfere with the same pathway as isocoumarins derivatives. (C) 2012 Elsevier Ltd. All rights reserved.

  硼替佐米的基于合理拓扑的支架跳跃发现新型20S蛋白酶体抑制剂

  摘要：

  基于硼替佐米的基于合理拓扑的支架跳跃，已经开发了一系列结构新颖的蛋白酶体抑制剂1 – 12。在这些新型蛋白酶体抑制剂中，化合物10代表了一项重要的进步，因为它具有 与硼替佐米相当的蛋白酶体抑制活性（IC 50 = 9.7 nM）（IC 50  = 8.3 nM），明显更高的BEI和SEI值以及对代谢稳定性的有效性。因此，化合物10提供了适合进一步优化的出色引线。

  acids, which selectively inhibit LMP7 while sparing all other subunits. The exploitation of structural differences between the proteasome subunits culminated in the identification of the highly potent, exquisitely selective, and orally available LMP7 inhibitor 50 (M3258). Based on the strong antitumor activity observed with M3258 in MM models and a favorable preclinical data package, a phase I clinical

  Boronic acids are an increasingly important compound class for many applications, including C–C bond formation reactions, medicinal chemistry, and diagnostics. The deprotection of boronic ester intermediates is frequently a problematic and inefficient step in boronic acid syntheses. We describe an approach that highly facilitates this transformation by leveraging the volatility of methylboronic acid and

  pinacol esters of various boronic acids via fluoroborane intermediates were evaluated. Treatment of the boronate esters with potassium hydrogen difluoride normally gives trifluoroborate salts; in the case of α-amido alkyl or o-amido phenyl boronate esters, aqueous workup gives difluoroboranes. Procedures for transformation of both trifluoroborates and difluoroboranes to free boronic acids are described.
