G-36, GPER Antagonist is a cell permeable, nonsteroidal, high-affinity, selective antagonist of GPER

* Required Fields


G-36 is a cell permeable, nonsteroidal, high-affinity, selective antagonist of GPER. GPER/GPR30 is a seven-
transmembrane G protein-coupled estrogen receptor that regulates many aspects of mammalian biology and
physiology. G36 is available in addition to the previously described GPER-selective agonist G-1 (AZ00001-G36)
and antagonist G15 (AZ00001-G15), all based on a tetrahydro-3H-cyclopenta[c]quinoline scaffold. G36 shows
decreased binding and activation of ERa compared to G15, while maintaining its antagonist profile towards
GPER. G36 selectively inhibits estrogen-mediated activation of PI3K by GPER but not ERa. It also inhibits
estrogen- and G-1-mediated calcium mobilization as well as ERK1/2 activation, with no effect on EGF-
mediated ERK1/2 activation. Similar to G15, G36 inhibits estrogen- and G-1-stimulated proliferation of uterine
epithelial cells in vivo. The identification of G36 as a GPER antagonist with improved ER counterselectivity
represents a significant step towards the development of new highly selective therapeutics for cancer and
other diseases.
