Steroidsulfatase-IN-2 is an active inhibitor of steroidsulfatase (STS), demonstrating an IC50 value of 109.5 nM. Its potential application lies in hormone-dependent cancer research, specifically estrogen-dependent breast and endometrial cancer [1].
Steroidsulfatase-IN-3 (compound 1q) is a highly effective Steroidsulfatase (STS) inhibitor, exhibiting an IC 50 value of 25.8 nM. This compound also demonstrates antiproliferative properties against T-47D estrogen-dependent breast cancer cells, with an IC 50 of 1.04 μM [1].
Steroidsulfatase-IN-1 is a highly potent and orally active inhibitor of the enzyme Steroidsulfatase, with an impressive IC50 value of 1.71 μM. This compound exhibits notable antitumor activity, achieving a TGI (tumor growth inhibition) of 51% in vivo. Therefore, Steroidsulfatase-IN-1 holds great promise in the field of breast cancer research [1].
Steroidsulfatase 17β-HSD1-IN-1 is a highly effective inhibitor of both steroidsulfatase and 17β-hydroxysteroid dehydrogenase type 1 (17β-HSD1) activities, displaying an IC50 value of 28 nM against cellular human steroidsulfatase. This compound holds significant potential for investigating estrogen-dependent diseases [1].
