一般建议 | 为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。溶液形式一般不宜长期储存,请尽快用完。 |
AY-NH2是PAR4的选择性激动剂,EC50值为11 μM [1].
蛋白酶活化受体-4(PAR4)是PARs的成员,通过作用于G蛋白i\12/13(Rho和Ras活化)和q(钙信号),从而在介导凝血酶的细胞效应中起重要作用[2].
AY-NH2是高效的PAR4激动剂,比GYPGKF-NH2具有更高(约10倍)的活性.大鼠血小板凝集实验表明,AY-NH2比GY-NH2和GF-NH2具有更高的血小板凝集能力[1].野生型C57BL6小鼠分离出的富含血小板的血浆实验中,AY-NH2处理对PAR4表现出较高的激动活性,而对其它PARs没有作用[3].
在雄性Wistar大鼠足肿胀模型中,腹腔注射AY-NH2在响应毒性与非毒性机械刺激时能显著降低感受伤害评分,从而抑制角叉菜胶诱导的机械痛觉过敏和异常性疼痛[4].
