Biochem/physiol Actions

ML194 (CID9581011) is an antagonist of GPR35, a GPRC receptor expressed in nervous system tissue, in the GI tract particularly in pancreas and small intestine, followed by colon, spleen, and immune cells, and also expressed in gastric carcinomas. GPR35 is being investigated for potential therapeutic importance in a variety of areas including pain, hypertension, cancer, diabetes and asthma. ML194 is more membrane penetrant and more potent than earlier synthetic antagonists, with an IC50 of 160nM. ML194 was also found to rescue the cell-surface expression of mutant GPR35 receptors, likely acting as a pharmacological chaperone to alter the misfolded receptor structure.

G Proteins (Heterotrimeric)

Heterotrimeric G proteins, comprising α, β and γ subunits, respond to extracellular signals generated by activated seven-transmembrane (7TM) receptors by modulating intracellular effector proteins such as enzymes and ion channels.

Discover Bioactive Small Molecules for Cyclic Nucleotides

Cyclic nucleotides, including cyclic AMP (cAMP), cyclic GMP (cGMP) and cyclic ADP-ribose, have been extensively studied as second messengers of intracellular events initiated by activation of GPCRs. cAMP modifies cell function in all eukaryotic cells, principally through the activation of cAMP-dependent protein kinase (PKA), but also through cAMP-gated ion channels and guanine nucleotide exchange factors directly activated by cAMP.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
