Recent efforts to identify treatments for chronic diabeticcomplications have resulted in the discovery of a novel series of highly potent and selective 3-[(benzothiazol-2-yl)methyl]indole-N-alkanoic acid aldosereductaseinhibitors. The lead candidate, 3-[(4,5,7-trifluorobenzothiazol-2-yl)methyl]indole-N-acetic acid (lidorestat, 9) inhibitsaldosereductase with an IC(50) of 5 nM, while being 5400

Enantioenriched chiral indoles are of high interest for the pharmaceutical and agrochemical industries. Herein, we present an asymmetric Fukuyama indolesynthesis through a mild and efficient radical cascade reaction to access 2-fluoroalkylated 3-(α-cyanobenzylated) indoles by stereochemical control with a chiral copper-bisoxazoline complex using 2-vinylphenyl arylisocyanides as radical acceptors and
对映体富集的手性吲哚引起了制药和农用化学工业的高度关注。在此,我们提出了一种不对称福山吲哚合成方法,通过温和有效的自由基级联反应,通过手性铜-双恶唑啉络合物的立体化学控制,使用2-乙烯基苯基芳基异氰化物作为自由基受体和氟烷基,获得2-氟烷基化的3-(α-氰基苄基化)吲哚。碘化物作为 C-自由基前体。异腈部分的自由基加成、5 -exo -trig 环化和 Cu 催化的立体选择性氰化为目标吲哚提供了优异的对映选择性和良好的产率。由于需要区分的两个芳基取代基具有相似的电子和空间性质,氰基二芳基甲烷立体中心的对映选择性构建极具挑战性。机理研究揭示了负非线性效应,允许提出一个模型来解释立体化学结果。证明了对映体富集的 3-(α-氰基苄基化)吲哚作为手性色胺、吲哚-3-乙酸衍生物和三芳基甲烷的中心的可扩展性和潜在用途,并公开了天然产物类似物的正式合成。

Discovery of the cancer cell selective dual acting anti-cancer agent (Z)-2-(1H-indol-3-yl)-3-(isoquinolin-5-yl)acrylonitrile (A131)
Selective targeting of cancer cells over normal cells is a key objective of targeted therapy. However few approaches achieve true mechanistic selectivity resulting in debilitating side effects and dose limitation. In this work we describe the discovery of A131 (4a), a new agent with an unprecedented dual mechanism of action targeting both mitosis and autophagy. Compound 4a was first identified in a phenotypic screen in which HeLa cells treated with 4a manifested mitotic arrest along with formation of multiple vesicles. Further investigations showed that 4a causes an increase in mitotic marker pH3 and autophagy marker LC3. Importantly 4a induces cell death in cancer cells while sparing normal cells which regrow after 4a is removed. Dual activities against pH3 and LC3 markers are required for cancer cell selectivity. An extensive SAR investigation confirmed 4a as the optimal dual inhibitor with potency against a panel of 30 cancer cell lines (average antiproliferative GI(50) 1.5 mu M). In a mouse model of paclitaxel-resistant colon cancer, 4a showed 74% tumor growth inhibition when administered at a dose of 20 mg/kg IP twice a day. (C) 2018 Elsevier Masson SAS. All rights reserved.
