Abstract
A series of androstano[17,16-
c]pyrazolines and their oxidized derivatives were synthesized by using
3β-hydroxyandrostan-17-one as starting material.
A series of androstano[17,16-
c]pyrazolines and their oxidized derivatives (
2–
14) were synthesized using 3β-hydroxyandrostan-17-one as a starting material (
1a,
b). The synthesized compounds were evaluated for their antiandrogenic activity compared to that of Cyproterone
® as positive control. Some of the compounds exhibited better antiandrogenic activity than the reference drug. The detailed synthesis, spectroscopic data, ED
50, and toxicity (LD
50 and LD
90) of the synthesized compounds were reported.
