  A low toxic CRM1 degrader: Synthesis and anti-proliferation on MGC803 and HGC27

  摘要：

  Chromosome region maintenance 1 (CRM1) is the sole nuclear exporter of several tumor suppressor, a growth regulatory protein as an attractive cancer drug target. In the present work, a novel CRM1 degrader was discovered from newly synthesized alpha, beta-unsaturated-delta-lactone based on a natural product Goniothalamin. It induces apoptosis of both MGC803 and HGC27 cell lines via degrading CRM1. Selective inhibition was observed for the proliferation of gastric cancer cell lines MGC803, HGC27 comparing to Human Gastric Mucosal Epithelial Cell Line (GES1). For the first time, CRM1 inhibitor or degrader inducing apoptosis in gastric carcinoma was investigated. (C) 2020 Elsevier Masson SAS. All rights reserved.

  reaction at the benzylic carbon of the epoxide ring. A reversal of regioselectivity (91:1–69:31) in favor of the reaction at the terminal carbon of the epoxide ring was observed for reaction with morpholine. The regioselectivity was dependent on the electronic and steric factors of the epoxide and the pKa of the amine and independent of amine nucleophilicity. The role of the metal tetrafluoroborates is

  The kinetic resolution of 1-chloro-3-[4-(2-methoxyetliyl)phenoxy]-2-propanol rac-4 with Novozym 435 and vinyl stearate, a key step in the gram-scale synthesis of (2S)-2-[[(2R)-2-hydroxy-3-[4-(2-methoxyethyl)phenoxy] propyl]amino]-1-butanol (R,S)-1 a potent antihypertensive agent currently under investigation, is reported here. Our approach differs from the previously reported synthesis, which involves a tedious and poorly effective fractional crystallization of (R,S)-1. This novel approach incorporates an enzymatic resolution for the efficient preparation of the oxirane precursor (R)-3. The two main advantages arising from this strategy are the high enantioselectivity of the enzymatic process and the facilitated recovery of the hydrophobic stearate intermediate (S)-5.
