Thiourea-based spacers in potent divalent inhibitors of Pseudomonas aeruginosa virulence lectin LecA.


PMID 26372329

Abstract

A new divalent highly potent inhibitor of the Pseudomonas aeruginosa lectin and virulence factor LecA was prepared. It contains two thiourea linkages which were found to be in the Z,Z isomeric form. This brings the spacer into an elongated conformation required to bridge the two binding sites, which results in the chelating binding mode responsible for the high potency.
