lydicamycin

Lydicamycin is a new antibiotic isolated from the fermentation broth of an actinomycete strain identified as Streptomyces solani. Lydicamycin is active against Gram-positive bacteria and certain yeasts, but inactive against Gram-negative bacteria. [2]

TPU-0037C is a metabolite of the marine actinomycete S. platensis that is structurally similar to lydicamycin . It is active against Gram-positive bacteria (MICs = 0.39-3.13 μg/ml), including methicillin-resistant S. aureus strains (MIC = 3.13 μg/ml), but is ineffective against Gram-negative bacteria (MICs = >50 μg/ml).

TPU-0037A is an antibiotic and a congener of lydicamycin. It inhibits the growth of Gram-positive bacteria, including methicillin-resistant S. aureus (MRSA), B. subtilis, and M. luteus (MICs = 1.56-12.5 μg ml), but not Gram-negative E. coli, P. mirabilis, P. vulgaris, or P. aeruginosa strains (MICs = >50 μg ml).
