CGH 2466 dihydrochloride是一个联合腺苷受体拮抗剂。它是磷酸二酯酶4型和p38促分裂原活化蛋白激酶的抑制剂。它抑制了磷酸二酯酶4D(PDE4D)同工酶,IC50值为22 ± 5 nM。它抑制p38促分裂原活化蛋白(MAP)激酶α和β的IC50值分别为187 ± 18,400 ± 38 nM[1]。
G蛋白偶联受体家族四个腺苷受体亚型包含A1、A2A、A2B和A3[2]。腺苷在炎症的控制中发挥重要作用[3]。磷酸二酯酶可以使cAMP失活。在炎症细胞中,磷酸二酯酶-4(PDE4)是主要的同功酶[4]。在哺乳动物细胞中,p38 MAPK通过调控促炎分子的表达,在感染中调控细胞反应方面具有重要作用[5]。
CGS15943是一种广谱腺苷拮抗剂,SB203580是p38MAP激酶的一个典型的抑制剂,西洛司特是PDE4的一个标准抑制剂。数据表明,作为p38MAP激酶抑制剂,CGH2466与SB203580的效力类似,在抑制PDE4D的活性方面,其功能类似于cilomilast。相比CGS15943,CGH 2466对于抑制A1、A2B和A3腺苷受体显示相似的效力。与CGS15943相比,CGH2466对A 2A受体没有活性。与其它上述化合物相比,在基于白细胞的测定法中,CGH2466是抑制特定酶或受体的最高效抑制剂[1]。
过敏原攻击48小时后,支气管肺泡灌洗回收嗜酸性粒细胞。在致敏小鼠中,卵清蛋白气溶胶攻击能够增加这些嗜酸性粒细胞数目。在哮喘的炎症动物模型中,攻击前15分钟和攻击后24小时,当鼻内给药剂量为3和10 mg/kg的CGH2466会剂量依赖性地抑制由卵清蛋白诱导的气道嗜酸粒细胞增多,并达到显著水平[1]。
