37.2 nM (calcium assay) and 51.3 nM (β-arrestin assay). Selectivity was assessed vs. related receptors including P2X, P2Y, and adenosine receptor subtypes, as well as ectonucleotidases. AR-C118925 showed at least 50-fold selectivity against the other investigated targets, except for the P2X1 and P2X3 receptors which were blocked by AR-C118925 at concentrations of about 1 μM. AR-C118925 is soluble in
对于g q蛋白偶联,ATP-和UTP激活P2Y 2受体是用于一系列不同的疾病,包括肿瘤转移,炎症,动脉粥样硬化,肾脏疾病,和骨质疏松症的潜在药物靶标,但药理学研究由限制阻碍合适的拮抗剂的可用性。最有效和选择性的拮抗剂之一是硫尿嘧啶衍生物AR-C118925。然而,该化合物直到最近才可商购,并且对其性质知之甚少。因此,我们开发了一种改进的合成AR-C118925和两种衍生物的方法,以实现放大生产,并评估了其在人和大鼠P2Y 2的钙动员测定中的功效。受体在1321N1星形细胞瘤细胞中重组表达。进一步评估了该化合物对P2Y 2受体诱导的β-arrestin移位的抑制作用。AR-C118925表现为p A 2的竞争性拮抗剂值分别为37.2 nM(钙测定)和51.3 nM(β-arrestin测定)。评估相对于相关受体(包括P2X,P2Y和腺苷受体亚型以及外切核苷酸酶)的选择性。除了P2X1和P2X
