Iturin A-2 is a cyclic lipopeptide discovered in B. subtilis and exhibits inhibitory activity against the plant pathogenic fungus P. expansum (MIC = 8 µg/disk). Iturin A-2 is cytotoxic to MCF-7 and BT474 breast cancer cells, as well as HeLa cervical cancer cells, with IC50 values of 66.81, 95.04, and 77.5 µg/mL, respectively. In greenhouse studies, Iturin A-2 at concentrations of 100 and 300 mg/kg Iturin A-2 reduces the lesion area of southern corn leaf blight caused by B. maydis, and in field studies, concentrations of 300 and 500 mg/kg Iturin A-2 reduce the incidence of the disease. Iturin A-2 (12.5 µg/mL) inhibits cell division, but not nuclear division, in isolated fertilized starfish eggs[1][2][3][4].
