title: Synthesis and biological evaluation of novel daunorubicin-estrogen conjugates.
abstract: The synthesis of two novel daunorubicin-estrogen conjugates with a steroidal and a non-steroidal ligand was undertaken in an attempt to target the cytotoxicity of anthracycline to estrogen-receptor positive cells. These conjugates (3 and 4), in contrast to their corresponding ligands, displayed weak binding affinities of 0.079 and 0.851 for the estrogen receptor. Conjugate 3 was consistently more cytotoxic than 4, which however showed some selectivity to estrogen receptor positive cell lines.
