Ikarugamycin is a macrocyclic antibiotic first isolated from Streptomyces sp. that demonstrates potent antiprotozoal activity. It exhibits cytotoxic effects in cancer cell lines, inhibiting cell proliferation (IC50 = 221.3 nM in HL-60 cells) through genotoxicity and by inducing apoptosis and activation of caspases....

An antiprotozoal antibiotic found to inhibit cholesteryl ester accumulation in macrophage. Shown to be efficient inhibitor of clathrin-coated pits-dependent endocytosis.
