filipin ii

Filipin II is a polyene and an active component of the polyene antibiotic filipin complex . [1] It has broad-spectrum antifungal activity, reducing growth of various fungi, including B. dermatitidis, C. neoformans, and H. capsulatum (MICs = 1-10 μg/ml). Filipin II inhibits ADP-stimulated respiration in rat liver mitochondria when used at a concentration of 3.5 mg/ml. [2] It also induces hemolysis of liposomes in a cholesterol-independent manner (IC50 = 0.5 μg/ml).[3]

Filipin III 是从菌株KPE18H 中提取得到，具有显著的抗真菌活性。Filipin III 也被广泛用作生物膜中胆固醇定位的荧光探针。当 Filipin III 与游离胆固醇结合后，其最大激发光波长约为 360 nm，最大发射光波长约为 480 nm。
