Anin situscreening assay for UDP-galactopyranose mutase (UGM, an essential enzyme ofM. tuberculosiscell wall biosynthesis) has been developed to discover novel UGM inhibitors. The approach is based on the amide-forming reaction of an amino acid core with various cinnamic acids, followed by a direct fluorescence polarization assay to identify the best UGM binders without isolation and purification of the screened ligands. This assay allows us to perform one-pot high-throughput synthesis and screening of enzyme inhibitors in a 384-well plate format. UGM ligands were successfully identified by this technology and their inhibition levels were established from pure synthetic compoundsin vitroand in a whole cell antibacterial assay. This study provides a blueprint for designing enamide structures as new UGM inhibitors and anti-mycobacterial agents.

A simple and straightforward approach to the diastereoselective synthesis of noncoded β-hydroxy-α-amino esters from Morita-Baylis-Hillman (MBH) adducts is described. The strategy is based on a one-pot sequence involving an oxidative cleavage of the double bond of silylated Morita-Baylis-Hillman adducts, followed by the reaction with hydroxylamine hydrochloride/pyridine to form oximes. The stereoselective reduction of the oximes with the mixture MoCl5·nH2O/NaBH3CN led to the corresponding anti-β-hydroxy-α-amino esters in four steps in good overall yield and with diastereoselectivity higher than 95%. A slight modification of the synthetic approach has allowed for the racemic synthesis of a set of noncoded α-amino esters/acids and DOPA
