产品名称

(trans-Cinnamoyl)-YPGKF-NH2 TFA

产品介绍

tcY-NH2 ((trans-Cinnamoyl)-YPGKF-NH2) TFA 是一种有效的PAR4选择性肽类拮抗剂。tcY-NH2 TFA 抑制凝血酶和 AY-NH₂诱导的血小板聚集和内皮抑素释放，可用于炎症、免疫学的研究。

生物活性

tcY-NH2 ((trans-Cinnamoyl)-YPGKF-NH2) TFA is a potent selectivePAR4antagonist peptide. tcY-NH2 TFA inhibits thrombin- and AY-NH₂-induced platelet aggregation and endostatin release, and can be used in the research of inflammation, immunology^[1]^[2]^[6].

体外研究
(In Vitro)

tcY-NH2 TFA (0-500 μM) inhibits AYPGKF-NH₂(10 μM)-induced platelet (obtained from male albino Sprague–Dawley rats) aggregation, with an IC₅₀value of 95 μM^[1].
tcY-NH2 TFA potently activates aorta relaxation (RA) and gastric (LM) contraction, with IC₅₀values of 64 μM (RA) and 1 μM (LM)^[1].
tcY-NH2 TFA (Tc-YPGKF-NH₂, 400 μM, 5 min) prevents endostatin release and platelet aggregation induced by thrombin or by AY-NH₂^[2].
tcY-NH2 TFA (5 μM, 15 min) decreases infarct size (IS) by 51%, and increases recovery of ventricular function by 26% in an isolated heart model^[5].

体内研究
(In Vivo)

tcY-NH2 TFA (tail vein injection, 0.6 mg/kg for a single dose) alleviates liver injury in Brain death (BD) rat model, indicated by lower serum ALT/AST levels and better histomorphology^[3].
tcY-NH2 TFA (intraperitoneal injection, 0.6 mg/kg for a single dose) increases posttraumatic activation of CD4⁺Tregs within the draining lymph nodes in burn injury mice model^[4].
tcY-NH2 TFA (intrapleural injection, 40 ng/kg for a single dose) inhibits neutrophil recruitment in experimental inflammation in mice^[6].

Animal Model:	Brain death (BD) rat model^[3]
Dosage:	0.6 mg/kg for a single dose
Administration:	Tail vein injection for a single dose
Result:	Reduced blood platelet activation and hepatic platelet accumulation. Attenuated the inflammatory response and apoptosis in the livers. Inhibited the activation of NF-κB and MAPK pathways induced by Brain death (BD).

Animal Model:	Burn injury model of C57BL/6 N mice^[4]
Dosage:	0.6 mg/kg for a single dose
Administration:	Intraperitoneal injection
Result:	Increased expression and phosphorylation of PKC-θ in the presence of platelets, without affecting early posttraumatic hemostasis.

Animal Model:	BALB/c mice^[6]
Dosage:	40 ng/kg for a single dose
Administration:	Intrapleural injection
Result:	Abolished the number of rolling and adhering neutrophils on the vessel wall. Inhibited CXCL8- and Cg-induced neutrophil migration into the pleural cavity of mice.
