Discovery and screening of the humimycins. Top: the humimycins were predicted from closely related gene clusters found in two Rhodococcus spp. cultured from human subjects. Center: chemical structures of humimycin A and B; the two antibiotics differ only at the fourth (F or Y) and sixth (V or I) residues. Bottom: MIC values for the humimycins against a panel of human commensal and pathogenic bacteria; the humimycins were particularly active against bacteria in the Staphylococcus and Streptococcus genus.
