  Synthesis and antiproliferative activity of benzo[d]isothiazole hydrazones

  摘要：

  Several benzo[d]isothiazole hydrazones have been evaluated for their potential antiretroviral activity. Since a number of these compounds were found to be inactive against viruses, but showed cytotoxicity at micromolar concentrations against the human CD4(+) lymphocytes (MT-4) that were used to support HIV-1 growth, they were further tested for antiproliferative activity. The compounds resulted as being cytotoxic for MT-4 cells and new derivatives which were rationally designed and synthesized, were tested for antiproliferative activity against several leukaemia and solid, tumour cell lines. In addition, these compounds were evaluated against "normal" cell lines. Compound 2h proved to be the most active compound and the fragment -CO-NH-N=CH-2-hydroxyphenyl was identified as being very important for biological activity, suggesting intramolecular, hydrogen bond formation or favourable mutual disposition between two important centres in the pharmacophore. H-1-NMR spectra have been explained with the support of a conformational analysis. (c) 2006 Elsevier SAS. All rights reserved.

  具有潜在抗菌活性的新型 1,2-苯异噻唑衍生物的实验和计算亲脂性指数的合成和相关性

  摘要：

  由环状（1和4）或非环状（2、3和5）1合成了具有潜在抗菌活性的五个系列新型腙（1a-m、2a-m、3a-m、4a-m、5a-m）， 2-苯并异噻唑基酰肼和表征。适当的酰肼与醛缩合得到设计的化合物。使用带有不同疏水取代基的醛，并设计了五个系列，以便同系物之间的疏水性也不同。保留参数通过 HPLC 测量，使用去活的烷基键合硅胶柱和不同的洗脱液系统（甲醇 - 水性缓冲液，乙腈 - 水）。将疏水性色谱参数 (log k') 与通过测量正辛醇和水之间的溶质分配 (log P) 提供的参数以及理论分配系数进行比较，由碎片法计算并根据实验值进行缩放。报告和讨论了不同疏水性指数之间的相关性

  The synthesis and the anti-HIV-1 activity of novel benzo[d]isothiazole hydrazones are reported. Target compounds tested in MT-4 cells cultures for their anti-HIV properties against wild type HIV-1 and HIV strains carrying clinically relevant mutations (EFV(R), Y181C and K103/Y181C) showed good activity against wild type HIV-1 and against the EFVR mutant. In terms of SAR the relevant result was that, in the class of benzisothiazole hydrazones, the benzo[d]isothiazol-3(2H)-one moiety (compounds 1 and 4) is an essential structural requirement for the anti-retroviral activity.
