Apoptolidin 

Apoptolidin is a polyketide isolated from Nocardiopsis bacteria^[1]. Apoptolidin is a selective mitochondrial F₁F_O ATPase inhibitor. Apoptolidin is an apoptosis inducer and induces apoptotic cell death in cells transformed with the adenovirus type 12 oncogenes including ElA (IC₅₀=10-17 ng/ml) but not in normal cells^[1][2].

Apoptolidin has cytotoxicity against normal and transformed cells, it against RG-E1A-7,RG-E1A19K-2, RG-E1A54K-9, RG-E1-4 and Adl2-3Y1 with IC₅₀ values of 11 ng/ml,10 ng/ml,13 ng/ml, 10 ng/ml and 17 ng/ml, respectively^[1].
