Phenylglycine and phenylalanine derivatives as potent and selective HDAC1 inhibitors (SHI-1)
摘要:
An HTS screening campaign identified a series of low molecular weight phenols that showed excellent selectivity (> 100-fold) for HDAC1/HDAC2 over other Class I and Class II HDACs. Evolution and optimization of this HTS hit series provided HDAC1-selective (SHI-1) compounds with excellent anti-proliferative activity and improved physical properties. Dose-dependent efficacy in a mouse HCT116 xenograft model was demonstrated with a phenylglycine SHI-1 analog. (C) 2008 Elsevier Ltd. All rights reserved.
Suppression of racemization in the carbonylation of amino acid-derived aryl triflates
摘要:
The carbonylation of enantiopure phenylglycine-derived aryl triflates was achieved to afford 4-carboxyphenylglycine analogs with high enantiomeric excesses (88 to >99% ee). Amide analogs of phenylglycine were well-tolerated in the hydroxy- and methoxycarbonylation processes, providing efficient access to benzoic acid and ester building blocks. The % ee of the product was dependent on the relative steric bulk of both the amino acid substrate and the requisite amine base, with (Pr2NEt)-Pr-i proving optimal in minimizing product racemization.
