title: Antimycoplasmal activities of the pseudomonic acids and structure-activity relationships of monic acid A derivatives.
abstract: The antimycoplasmal activities of the pseudomonic acids isolated from Pseudomonas fluorescens NCIB 10586 are reported. Structure-activity relationships of a variety of ester, amide and thiol ester derivatives of the nucleus, monic acid A, are described. Enhanced antimycoplasmal activity is reported for a number of monic acid A esters and the most potent derivative, m-nitrobenzyl monate A, is a 100-fold more active against Mycoplasma hyopneumoniae than pseudomonic acid A.
