  摘要：

  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。

  To further investigate our hypothesis on the structure of the platelet-activating factor (PAF) receptor, 35 compounds derived from 1,4-bis(3',4',5'-trimethoxybenzoyl)piperazine were synthesized and their in vitro antagonistic effect was measured. Substitution of the compounds in position 2, by ester or carbamate groups, giving increased steric hindrance and hydrophobicity, increased the platelet aggregation inhibitory activity from 2 muM (without substitution, compound 2) to 0.07 muM (compound 1h) arid gave a maximum displacement of [H-3]PAF from platelet membrane of 0.05 muM (compound 1k). It appears that the PAF antagonistic effect is only weakly enantiospecific, as observed in many cases including antagonists structurally related or not to PAF. 3D electrostatic potential maps (calculated at -10 kcal/mol) of such compounds revealed a double ''Cache-oreilles'' (ear-muffs) system. One of these systems has been previously described (distance between atoms generating negative wells, 11-14 angstrom). The second shorter ''Cache-oreilles'' (6-7 angstrom) system appears to be required for increased PAF antagonistic activity. This short distance between groups generating the negative wells is present in the gingkolides, a series of naturally occurring PAF antagonists. The present study indicates that the structure of the PAF receptor may be more complicated than our initial hypothesis and may be a tetrapolarized structure, with alternants of electropositive and hydrophobic areas. This modified hypothesis is in agreement with recent publications concerning PAF antagonists bearing a cationic moiety.

  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
