Synthesis and estrogenic activity of BODIPY-labeled estradiol conjugates.

Novel BODIPY-estradiol conjugates have been synthesized by selecting position C-3-O for labeling. The conjugation strategy was based on Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) or etherification. Estradiol derivatives used as azide partners bearing an ω-azidoalkyl function through C-C-long linkers have been prepared.

Cytotoxic effect of 13α-estrane derivatives on breast, endometrial and ovarian cancer cell lines.

Hormone-dependent cancers such as breast, uterine, and ovarian cancers account for more than 35% of all cancers in women. Worldwide, these cancers occur in more than 2.7 million women/year and account for 22% of cancer-related deaths/year.
