- Proline-based hydroxamates targeting the zinc-dependent deacetylase LpxC: Synthesis, antibacterial properties, and docking studies
-
The Zn2+-dependent deacetylase LpxC is an essential enzyme in Gram-negative bacteria, which has been validated as antibacterial drug target. Herein we report the chiral-pool synthesis of novel D- and L-proline-derived 3,4-dihydroxypyrrolidine hydroxamates and compare their antibacterial and LpxC inhibitory activities with the ones of 4-monosubstituted and 3,4-unsubstituted proline derivatives. With potent antibacterial activities against several Gram-negative pathogens, the L-proline-based tertiary amine 41g ((S)-N-hydroxy-1-(4-{[4-(morpholinomethyl)phenyl]ethynyl}benzyl)pyrrolidine-2-carboxamide) was found to be the most active antibacterial compound within the investigated series, also showing some selectivity toward EcLpxC (Ki = 1.4 μM) over several human MMPs.

- SYNTHESIS FROM D-MANNOSE OF 1,4-DIDEOXY-1,4-IMINO-L-RIBITOL AND OF THE α-MANNOSIDASE INHIBITOR 1,4-DIDEOXY-1,4-IMINO-D-TALITOL
-
The syntheses of 1,4-dideoxy-1,4-imino-L-ribitol and of 1,4-dideoxy-1,4-imino-D-talitol from D-mannose are described. 1,4-Dideoxy-1,4-imino-D-talitol is a specific and competitive inhibitor of human liver α-mannosidase in vitro and also blocks the lysosomal catabolism of asparigine-linked glycans of glycoproteins in vivo.
