CPI-1189是一种促细胞凋亡细胞因子肿瘤坏死因子(TNF)α的抑制剂。
AIDS痴呆综合征的特征在于CNS中神经胶质增生、细胞凋亡和氧化应激的增加,以及血脑屏障受损。据报道,TNF-α在AIDS痴呆综合征脑中升高并且可能有助于AIDS痴呆综合征。
体外:CPI-1189可以有效抑制p38-MAPK磷酸化,显示出对肿瘤坏死因子-α(TNFα)诱导的神经变性的保护作用。此外,在用白细胞介素1β处理的原代星形胶质细胞中,CPI-1189在低浓度下抑制p38-MAPK磷酸化[1]。
体内研究:为了模拟AIDS痴呆综合征中TNF-α的升高,将TNF-α输注到大鼠中。结果显示,与CPI-1189共给药防止TNF-α诱导的细胞凋亡。 TNF-α和CPI-1189治疗均可抑制胶质纤维酸性蛋白染色。TNF-α单独给药不显著影响血脑屏障的完整性,但是CPI-1189治疗增加了血脑屏障的完整性[2]。
临床试验:先前的临床研究显示,CPI-1189耐受性良好,其中91%接受CPI-1189治疗的受试者和76%接受安慰剂治疗的受试者完成试验。皮疹在安慰剂和药物治疗的手臂中同样存在。一名CPI-1189受试者发展为白内障。所有组中的 CD4淋巴细胞计数和血浆HIV病毒载量在整个试验期间保持稳定[3]。
