Saccharocarcin A is an antibiotic originally isolated from S. aerocolonigenes subsp. antibiotica. It is active against M. luteus, S. aureus, E. coli, P. aeruginosa, and C. albicans in a disc assay. Saccharocarcin A inhibits C. trachomatis infection by 88% without inducing cytotoxicity in McCoy cells when used at a concentration of 0.5 μg ml.
3-hydroxy Docosanoic acid is a hydroxylated form of the 22-carbon saturated docosanoic acid . It is found in lipopolysaccharides from C. trachomatis and C. psittaci and in S. synnaedendra. 3-hydroxy Docosanoic acid, in the form of an acyl-CoA metabolite, is an intermediate in fatty acid chain elongation from arachidic acid to docosanoic acid (C22:0).
KSK213 is a potent inhibitor of Chlamydia trachomatis Infectivity (EC50 = 60 nM). KSK213 potently inhibited multiple serovars of C. trachomatis while not affecting the growth of key species from the commensal flora or host cell viability at 25 μM.
