PAR4 |
tcY-NH2 (0-500 μM) inhibits AYPGKF-NH2 (10 μM)-induced platelet (obtained from male albino Sprague–Dawley rats) aggregation, with an IC50 value of 95 μM[1].
tcY-NH2 potently activates aorta relaxation (RA) and gastric (LM) contraction, with IC50 values of 64 μM (RA) and 1 μM (LM)[1].
tcY-NH2 (Tc-YPGKF-NH2, 400 μM, 5 min) prevents endostatin release and platelet aggregation induced by thrombin or by AY-NH2[2].
tcY-NH2 (5 μM, 15 min) decreases infarct size (IS) by 51%, and increases recovery of ventricular function by 26% in an isolated heart model[5].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
tcY-NH2 (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 (intrapleural injection, 40 ng/kg for a single dose) inhibits neutrophil recruitment in experimental inflammation in mice[6].
