Synthesis and uterotrophic activity of 2-substituted estradiol and ring A fused pyranone and furanone derivatives

ABSTRACT

Several new modified estradiol analogs have been synthesized and examined as potential estrogens. Nuclear modification involved the introduction of various substituents at the 2-position of estradiol and fusion of a heterocylic ring to position 2, 3 of ring A of the steroidal nucleus. Uterine weight assays in rats have shown that all tested compounds produced a moderate increase in uterine weight
