The HIV-1 central nervous system infection leads to the onset of neurological impairments called AIDS dementia complex (ADC). PAF plays an important role in this pathology, as it is an HIV-1-induced neurotoxin produced by infected or activated macrophages and microglia, in the brain. We previously reported that PAF-antagonists bearing a trisubstituted piperazine presented in vitro anti-HIV-1 activity
HIV-1中枢神经系统感染导致称为AIDS痴呆综合症(ADC)的神经功能障碍的发作。PAF在这种病理学中起着重要作用,因为它是由HIV-1诱导的神经毒素,它是由感染或激活的巨噬细胞和小胶质细胞在大脑中产生的。我们以前报道过,带有三取代哌嗪的PAF拮抗剂在人巨噬细胞中具有体外抗HIV-1活性。为了改善我们的先导化合物1a的药理活性,我们修改了其氨基甲酸酯功能并评估了其抗逆转录病毒和抗PAF活性。一种氨基甲酸酯衍生物(10c)具有相似的抗病毒活性,但具有更高的抗PAF效力,而具有酰脲功能的4a具有增强的抗病毒活性,可以视为纯的抗逆转录病毒药物,因为它不表现出PAF拮抗作用。此外,我们使用原位小鼠脑灌注方法及其静脉内和口服给药后的血浆浓度,测量了1a穿过血脑屏障的能力。测得的转运参数(K(in))证明1a能够穿越该生物屏障,但是药代动力学研究表明其在大鼠体内的生物利用度较弱。
