Fig. 1From: Effects of cytochalasin congeners, microtubule-directed agents, and doxorubicin alone or in combination against human ovarian carcinoma cell lines in vitroMolecular structure of the cytochalasin macrocycle and several congeners. The macrocycle skeleton of cytochalasins is provided to indicate the numbering system used for these congeners. In addition, the structure of 21,22-dihydrocytochalasin B is shown to indicate the differences in structure it has with the γ-lactone derivative. The α, β-unsaturated ketones of cytochalasin A runs from C-20 to C-23Back to article page
