(3aS,4R,9bR)-G-1

(3aS,4R,9bR)-G-1 is a highly selective G protein-coupled receptor GPR30 (GPER) agonist with a Ki value of approximately 7 nM. (3aS,4R,9bR)-G-1 activates rapid signaling pathways such as intracellular calcium mobilization and PI3K signaling through GPR30, promoting uterine epithelial cell proliferation and exerting antidepressant effects. (3aS,4R,9bR)-G-1 is promising for research of breast cancer and depression.
