产品名称

CJ-042794

产品介绍

CJ-42794 (CJ-042794) 是一种口服有效的选择性前列腺素E受体 4 (EP4) 拮抗剂，其IC₅₀值为 10 nM，其选择性是EP1、EP2和EP3的 200 倍。CJ-42794 可用于胃溃疡的研究。

生物活性

CJ-42794 (CJ-042794) is a potent, orally active, selectiveprostaglandin E receptor 4 (EP4)antagonist with anIC₅₀value of 10 nM, which is 200-fold more selective thanEP1,EP2andEP3. CJ-42794 can be used in research of gastric ulcers^[1]^[2].

IC₅₀& Target

10 nM (EC₅₀)

体外研究
(In Vitro)

CJ-042794 (CJ-042794, 0.3-5000 nM; 10 min; hEP4/HEK293 cells) inhibits the PGE₂-induced elevation of cAMP in a concentration-dependent manner with a pIC₅₀value of 7.5^[1].
CJ-042794 (3-3000 nM; 24 h) reverses the inhibitory effects of PGE₂(10 nM) on the LPS-induced TNFα production in human whole blood (HWB) in a concentration-dependent manner with a pIC50 value of 6.4^[1].

体内研究
(In Vivo)

CJ-042794 (CJ-042794; 0.3-3 mg/kg; i.d.; once) antagonizes the HCO3 stimulatory action of AE1-329 in the duodenum^[1].
CJ-042794 (30 and 50 mg/kg; p.o.; once) does not cause any damage to the gastric mucosa of normal rats and has no gastric ulcerogenic response to cold-restraint stress^[1].
CJ-042794 (30 and 50 mg/kg; p.o.; once) does not damage the stomach and small intestine of helper arthritis rats^[1].
CJ-042794 (3-45 mg/kg; p.o.; twice daily for 14 d; Sprague-Dawley rats) promotes spontaneous healing of gastric ulcers^[1].
CJ-042794 (10 mg/kg; p.o.; daily, for 7 d) repeats administration impairs the healing of chronic gastric ulcers with a down-regulation of vascular endothelial growth factor expression in the ulcerated mucosa^[1].

Animal Model:	Male Sprague-Dawley rats (200-230 g)^[1]
Dosage:	0.3, 1, and 3 mg/kg
Administration:	intradermal injection; once
Result:	Attenuated the PGE₂-stimulated HCO₃secretion in a dose-dependent manner and had the inhibition being 68.9% at 1 mg/kg.

Animal Model:	Male Sprague-Dawley rats (200-230 g)^[1]
Dosage:	30 and 50 mg/kg
Administration:	Oral administration; once
Result:	Did not produce any damage in the gastrointestinal mucosa. Did not produce gastric ulcerogenic response induced by cold-restraint stress.

Animal Model:	Dark Agouti (DA) rats (140-160 g)^[1]
Dosage:	30 and 50 mg/kg
Administration:	Oral administration; once
Result:	Caused any visible damage in the gastric mucosa of normal rats. Had little injurious effect on the small intestine of arthritic rats.

Animal Model:	Male Sprague-Dawley rats (200-230 g)^[1]
Dosage:	3, 10, and 45 mg/kg
Administration:	Oral administration; twice daily for 14 days
Result:	Healed ulcers gradually within 14 days, and the ulcer score on day 17 was 1.6 mm².

Animal Model:	Male Sprague-Dawley rats (200-230 g)^[1]
Dosage:	10 mg/kg
Administration:	Oral administration; daily for 7 days
Result:	Down-regulates the expression of VEGF and decreased the angiogenic response.
