CJ-42794 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 EP1EP2EP3 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, selective prostaglandin E receptor 4 (EP4) antagonist with an IC50 value of 10 nM, which is 200-fold more selective than EP1, EP2 and EP3. CJ-42794 can be used in research of gastric ulcers.

体外研究

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 pIC50 value of 7.5.
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.

体内研究

CJ-042794 (CJ-042794; 0.3-3 mg/kg; i.d.; once) antagonizes the HCO3 stimulatory action of AE1-329 in the duodenum.
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.
CJ-042794 (30 and 50 mg/kg; p.o.; once) does not damage the stomach and small intestine of helper arthritis rats.
CJ-042794 (3-45 mg/kg; p.o.; twice daily for 14 d; Sprague-Dawley rats) promotes spontaneous healing of gastric ulcers.
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.

Animal Model: Male Sprague-Dawley rats (200-230 g)
Dosage: 0.3, 1, and 3 mg/kg
Administration: intradermal injection; once
Result: Attenuated the PGE2-stimulated HCO3 secretion 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)
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)
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)
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)
Dosage: 10 mg/kg
Administration: Oral administration; daily for 7 days
Result: Down-regulates the expression of VEGF and decreased the angiogenic response.
