Description
G protein-
coupled estrogen receptor (GPER), or GPR30, specifically binds natural and man-
made estrogens. It is thought to be involved in estrogen-
sensitive cancers. GPER knockout mice are fertile, although they exhibit thymic atrophy, impaired glucose tolerance, and altered bone growth. G-
15 is a cell-
permeable non-
steroidal antagonist of GPER (K
i = 20 nM). It displays low affinity cross-
reactivity with the classical estrogen receptor (ER), ERα, so that at doses greater than 1 μM it is capable of mediating limited ER-
dependent transcriptional activity. G-
15 antagonizes the anti-
depressive effects of estrogen
in vivo.
Uses
(3aS,4R,9bR)-4-(6-Bromo-1,3-benzodioxol-5-yl)-3a,4,5,9b-tetrahydro-3H-cyclopenta[c]quinoline is also known as “G-15”, a G-protein-coupled estrogen receptor antagonist designed for the treatment of estrogen-sensitive cancers.
