human ip receptor

KAG-308 is an effective selective and orally active agonist of the EP4 receptor (Ki: 2.57 nM and EC50: 17 nM for human EP4 receptor), more selective over EP1, EP2, EP3, and IP receptor. KAG-308 suppresses colitis and promotes histological mucosal healing,

STING agonist 12b is an agonist of stimulator of interferon genes (STING).1It binds to STING (Kd= 26.4 μM) and induces interferon reporter gene expression in cells expressing human or mouse STING (EC50s = 7.45 and 10.23 μM, respectively). STING agonist 12b (40 μM) induces expression of TNF-a, IL-6, IP-10, and IL-1b in THP-1 cells. 1.Hou, S., Lan, X.-j., Li, W., et al.Design, synthesis and biological evaluation of acridone analogues as novel STING receptor agonistsBioorg.

Ralinepag (APD811) 是一种可口服的非前列腺素前列环素 (IP) 受体激动剂，对人和大鼠 IP 受体以及人 DP1 受体的 EC50 分别为 8.5、530 和 850 nM。

NBI-42902 is a potent inhibitor of peptide radioligand binding to the human GnRH receptor (K(i) = 0.56 nm). Tritiated NBI-42902 binds with high affinity (K(d) = 0.19 nm) to a single class of binding sites and can be displaced by a range of peptide and nonpeptide GnRH receptor ligands. In vitro experiments demonstrate that NBI-42902 is a potent functional, competitive antagonist of GnRH stimulated IP accumulation, Ca(2+) flux, and ERK1 2 activation. It did not stimulate histamine release from rat peritoneal mast cells. Finally, it is effective in lowering serum LH in castrated male macaques after oral administration. Overall, these data provide a benchmark of pharmacological characteristics required for a nonpeptide GnRH antagonist to effectively suppress gonadotropins in humans and suggest that NBI-42902 may have clinical utility as an oral agent for suppression of the hypothalamic-pituitary-gonadal axis.

Prostaglandin J2 (PGJ2) 是前列腺素 D2 (PGD2) 的一种内源性代谢物，是一种有效的 PGD2 受体 (DP) 激动剂，对 hDP 和 hCRTH2 的 Ki 分别为 0.9 nM 和 6.6 nM。Prostaglandin J2 刺激细胞内环 AMP 的产生，EC50值为 1.2 nM。Prostaglandin J2 诱导氧化应激和神经细胞凋亡。Prostaglandin J2 诱导泛素化 (Ub) 蛋白的积累 聚集。Prostaglandin J2 具有高度神经毒性，可导致许多神经退行性疾病，包括阿尔茨海默病 (AD) 和帕金森病 (PD)。

AC-42 hydrochloride为AC-42的盐酸盐形式.作为一种变构激动剂,它特异性激活毒蕈碱M1受体(muscarinic M1 receptor),在人类野生型M1受体和Y381A突变型M1受体上的EC50值分别是805 nM和220 nM.此外,AC-42 hydrochloride能有效促进CHO细胞内肌醇磷酸酯(IP)的积累及钙离子的动员.
