Distribution of biological functions of selective potent FXR-actives.
Thirty-five FXR-active drugs with submicromolar potency and known biological targets were chosen to form clusters based on biological functions. (a) Distribution of drug classes. (b) Distribution of target classes. (c) Concentration-dependent inhibition curves of nocodazole (IC50 = 320 nM), colchicine (IC50 = 11 nM), docetaxel (IC50 = 8 nM) and vincristine (IC50 = 9 nM) measured from the primary screen. (d) Chemical structures of nocodazole, colchicine, docetaxel and vincristine.
