G Protein

G15 is a high affinity and selective G-protein-coupled estrogen receptor (GPER/GPR30) antagonist with a Ki of 20 nM.

Kynurenic acid, an endogenous tryptophan metabolite, is a broad-spectrum antagonist targeting NMDA, glutamate, α7 nicotinic acetylcholine receptor. Kynurenic acid is also an agonist of GPR35/CXCR8.

CID16020046 is a selective GPR55 antagonist, inhibiting GPR55 constitutive activity with IC50 of 0.15 μM in yeast. It demonstrates weak activity against a broad spectrum of other GPCRs, ion channels, kinases, and nuclear receptor.

TM N1324 is an agonist of G-Protein-Coupled Receptor 39 (GPR39) with EC50s of 9 nM/5 nM in the presence of Zn2+, and 280 nM/180 nM in the absence of Zn2+ for human/murine GPR39.

DJ-V-159 is an agonist for G protein-coupled receptor family C group 6 member A (GPRC6A).

Kynurenic acid sodium, an endogenous tryptophan metabolite, is a broad-spectrum antagonist targeting NMDA, glutamate, α7 nicotinic acetylcholine receptor. Kynurenic acid sodium is also an agonist of GPR35/CXCR8.

PSN632408 is an optimized agonist of GPR119 receptors that shows similar potency to OEA at both recombinant mouse and human GPR119 receptors, exhibiting EC50 values of 5.6 and 7.9 uM, respectively.

Guanosine 5'-triphosphate trisodium salt (5'-GTP trisodium salt) is an activator of signal transduction of G proteins.
