Ikarugamycin is an antiprotozoal macrolactam antibiotic demonstrating cytostatic effects and activity against gram-positive bacteria. It is described to inhibit clathrin-dependent endocytosis, as well as oxidized LDL-induced accumulation of cholesteryl ester in macrophage J774. Ikarugamycin 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. It also exhibits anti-ulcer activity possibly by inhibition of Helicobacter.
