GPCR/G-Protéine

8 Hydroxy PIPAT oxalate is a selective 5-HT1A receptor agonist that enhances the spontaneous release of histamine by promoting the degranulation of mast cells in guinea pig and human intestinal preparations. By activating the serotonin signaling pathway, this compound demonstrates potential in regulating gastrointestinal functions and offers insight into the management and suppression of functional gastrointestinal disorders such as irritable bowel syndrome. Its effects in increasing histamine release could play a crucial role in gastrointestinal regulation.

Thielavin B, from Thielavia terricola, inhibits prostaglandin E2 synthesis and reduces rat oedema.

Beloxepin is an oral dual selective inhibitor of serotonin and norepinephrine uptake.

Compound (−)-19, also known as (-)-5-HT2C agonist-3, is a selective 5-HT2C agonist exhibiting a preference for Gq signaling. It demonstrates efficiency with EC50 values for 5-HT2 receptor subtypes as follows: 5-HT2C at 103 nM, 5-HT2B at 570 nM, and 5-HT2A at 72 nM. This compound is utilized in research on antipsychotics.

P2Y2 and P2Y4 receptor agonist

AL 6598, a prodrug of PGD2 agonist AL 6556, reduces IOP by 53% at 1μg twice daily in monkeys; binds DP receptors with Ki of 3.2μM.

Pentacosafluorotridecanoic Acid (PFTrDA) is a perfluoroalkyl substance (PFAS) that exhibits various biological impacts across different species. In zebrafish embryos, exposure to PFTrDA induces yolk sac edema and increases mRNA expression of thyroid hormone synthesis genes, including tshβ, at concentrations of 0.1 and 0.3 mg/L. At a dosage of 10 mg/kg, PFTrDA reduces serum testosterone and luteinizing hormone levels, as well as palmitic acid, linoleic acid, and oleic acid levels in the testicular interstitial cells of late adolescent rats. In humans, maternal plasma levels of PFTrDA during pregnancy are positively correlated with the development of eczema in female infants (but not male infants), and PFTrDA levels are higher in the livers of cancerous humans compared to non-cancerous ones. Additionally, PFTrDA is found in marine mammals.

CHNQD-01255 is an orally active inhibitor of Arf-GEFs that is effective against hepatocellular carcinoma (HCC).
