  Structure−Activity Relationships in Platelet-Activating Factor (PAF). 10. From PAF Antagonism to Inhibition of HIV-1 Replication

  摘要：

  Excessive levels of PAF and cells of macrophage lineage appear to play an important role in neuronal cell injury, inflammatory syndrome, and HIV replication in CNS resulting in AIDS dementia complex (ADC). The beneficial effects of PAF receptor antagonists are evident and give rise to expected therapeutic strategies for neurotrauma. Piperazine derivatives bearing a "cache-oreilles" (ear-muff) electronic distribution are able to inhibit in vitro PAF effects and, thus, could be used in pathologies where this mediator is involved. Therefore, their potential anti-HIV activity was investigated, and we find that (i) these PAF antagonists are effectively active in HIV-infected monocyte-derived macrophages (MDM) but there is no correlation between both anti-HIV and anti-PAF activities; (ii) the presence of a carbamate function (compounds 1a-d) is favorable to the antiviral activity; (iii) the lipophilicity of the substituent on the piperazinic cycle seems to be less important for the anti-PAF activity than for the antiviral one. Our leading compound, PMS 601 (compound la), presents a dual activity with IC50 of 8 and 11 mu M for anti-PAF and anti-HIV activity, respectively, without cytotoxic events at 1000 mu M in MDM. Although its mode of action is not clearly defined, these data suggest that PMS 601, which displays no effect on acellular reverse transcriptase or protease tests, deserves further investigation in the treatment of HIV-1-associated dementia.

  设计，合成和评价吡咯嗪衍生物作为二环酪氨酸（cYY）模拟物的结核分枝杆菌

  摘要：

  三个系列唑哌嗪衍生物的模拟dicyclotyrosine（CYY），必需的天然底物的结核分枝杆菌的细胞色素P450 CYP121A1，制备并评价针对结合亲和力和抑制活性（MIC）的结核分枝杆菌。系列A替代了一个酚基团CYY的与C3-咪唑部分，系列B包括在系列A咪唑之前的烃链上的酮基，而C系列探索用CH替换CYY的哌啶酮环的酮基2 -咪唑或CH 2-三唑部分，以增强与CYP121A1血红素的结合相互作用。除B 10a系列外，该系列对CYP121A1显示中等至弱II型结合亲和力，其中显示了混合的I型绑定。在这三个系列中，系列C咪唑衍生物显示出对结核分枝杆菌的最佳抑制作用，尽管抑制作用适中（17d MIC = 12.5μg/ mL，17a 50μg/ mL）。确定了与系列A化合物6a和6b结合的CYP121A1的晶体结构，这些化合物显示，咪唑基团位于血红素铁的正上方，并且两个化合物的血红素铁和咪唑氮之间的键合距离为2

  6-fluoro-7-substituted-1,4-dihydro-4-oxoquinoline-3-carboxylic acids have been prepared. At the N-1 position "standard" substitution was employed with the ethyl, cyclopropyl, and p-fluorophenyl groups being used. At C-7 the introduction of some novel piperazines was made. Most notably, 2-(fluoromethyl)piperazine (10) and hexahydro-6-fluoro-1H-1,4-diazepine (16, fluorohomopiperazine) at the quinolone C-7 position
