Hexestrol is a synthetic hydrogenated derivative of diethylstilbestrol (DES). Hexestrol exhibits strong affinity for estrogen receptors that are overexpressed in some types of cancers.  When conjugated with a neoplastic drug, hexestrol may selectively concentrate the cytotoxic agent in estrogen receptor-rich tumors.  This agent may also be mutagenic. (NCI04)
