Discovery and optimization of orally active cyclohexane-based prolylcarboxypeptidase (PrCP) inhibitors
摘要:
The synthesis, SAR, binding affinities and pharmacokinetic profiles are described for a series of cyclohexane- based prolylcarboxypeptidase (PrCP) inhibitors discovered by high throughput screening. Compounds show high levels of ex vivo target engagement in mouse plasma 20 h post oral dose. (C) 2013 Elsevier Ltd. All rights reserved.

use of gem-difluoro sulfinates in visible-light photocatalysis for the construction of new C−C bonds in a chiral fashion is presented. This was tackled by rerouting the chemical pathway of alkyl sulfonyl radicals from traditional sulfonylation to alkylation performance. The efficacy of these sulfinates for assisting SO2 extrusion is shown by allowing the installation of CF2-bearing scaffolds, a modern
介绍了宝石-二氟亚磺酸盐在可见光光催化中前所未有的用途,用于以手性方式构建新的 C-C 键。这是通过将烷基磺酰基自由基的化学途径从传统的磺酰化重新路由到烷基化性能来解决的。这些亚磺酸盐有助于 SO 2挤出的功效通过允许安装带有 CF 2的支架来显示,这是制药领域的一项现代任务。

A mild method is presented for the formation of N-acylated oxazolidinones that employs acid fluorides and mild bases, such as (i)Pr(2)NEt and NEt(3). Optimized reaction conditions for two types of substrates have been developed utilizing either the oxazolidinone itself or the corresponding in situ generated O-silyloxazolidinones resulting in the formation of the desired N-acylated products in high yields of up to 98%.

Accumulation of beta-amyloid (A beta), produced by the proteolytic cleavage of amyloid precursor protein (APP) by beta- and gamma-secretase, is widely believed to be associated with Alzheimer's disease (AD). Research around the high-throughput screening hit (S)-4-chlorophenylsulfonyl isoleucinol led to the identification of the Notch-1-sparing (9.5-fold) gamma-secretase inhibitor (S)-N-(5-chlorothiophene-2-sulfonyl)-beta,beta-diethylalaninol 7.b.2 (A beta (40/42) EC50 = 28 nM), which is efficacious in reduction of A beta production in vivo.
