Estrogen receptor agonists and antagonists...low cost, high quality
Estrogen modulates many cellular processes including growth, differentiation and function of the reproductive system. Estrogen receptors include:
- estrogen receptors ERα and ERβ, which are ligand-activated transcription factors belonging to the nuclear hormone receptor superfamily. Both receptors interact with the same DNA response element and have a similar pharmacological profile.
- estrogen-related receptors (ERRs): ERRα, ERRβ and ERRγ. These are activated by co-regulatory proteins and bind the ERE and ERR response elements (ERREs) as homodimers, exerting transcriptional control of energy homeostasis.
- the G protein-coupled estrogen receptor (GPER, GPR30) which is a seven transmembrane spanning receptor that couples to heterotrimeric Gs-proteins. It functions independently from ERα or ERβ estrogen receptors. The GPER binds estradiol with high affinity, but has lower affinity for estrone and estriol.

Featured estrogen receptor and signaling products
A potent estrogen receptor (ER) antagonist (Ki values are = 1 and 3.6 nM at ERα and ERβ respectively). Shows no agonist activity and is devoid of estrogenic activity. Also a high affinity agonist at GPER (GPR30). Down-regulates the ER and impairs nuclear shuttling and dimerization of the receptor. Shows anticancer activity and active in vivo..

Selective ERβ estrogen receptor agonist (Kd values are 5 and 400 nM at ERβ and ERα respectively). Shows 70-fold selectivity at ERβ over ERα. Shows neuroprotective effects. Active in vivo. Find out more
Cmpd101 is a novel, potent and selective G-protein coupled receptor kinase 2 and 3 (GRK2/GRK3) inhibitor (IC50 values are 35, 290 nM and 125 µM at GRK2, GRK3 and GRK5 respectively). It shows little activity at a broad range of other kinases. Membrane permeable, it can be used to study the roles of GRK2/3 in GPCR desensitization and other functions. Find out more…
Selective and reversible ATP-competitive c-Jun N-terminal Kinase (JNK) inhibitor (IC50 values are 40-90 µM at JNK1,2,3). Shows selectivity over a range of other kinases. Dose-dependently inhibits JNK phosphorylation and inhibits gene expression of COX-2, IL-2, IFN-γ and TNF-α. Prevents BMP9-induced osteogenic mesenchymal stem cell (MSC) differentiation. Active in vivo. Find out more...
