Structure-activity relationship studies of (E)-3,4-dihydroxystyryl alkyl sulfones as novel neuroprotective agents based on improved antioxidant, anti-inflammatory activities and BBB permeability
摘要:
(E)-3,4-双羟基苯基甲基硫醚作为神经退行性疾病药的新类同代物被设计并合成。生物测试结果表明,在清除自由基以及抗炎性反应中,大多数目标化合物保持了抗氧化和抗炎活性,从而保护神经细胞免受H2O2、6-羟基多巴胺和其他抗生物素药物等神经毒剂的侵害,并抑制了脂多糖(LPS)诱导的NO过度产生。其中,化合物6.22具有在低浓度下(2.5μM)表现出强烈抗氧化活性(细胞存活率=94.5%)特点。此外,化合物6.22(IC50=1.6μM)的抗炎活性略强于基准化合物1(IC50=13.4μM)。鉴于6.22在性能上的突出表现,检测了H2O2损伤的PC12细胞的凋亡率,通过附着抑制器V-FITC/PI试剂,结果表明在低浓度(2.5μM)下,6.22的抗凋亡活性比基准化合物1更高,这与抗氧化和抗炎作用类似。此外,基于计算预测其中枢神经系统的(+)和血脑屏障(BBB)通透性(P-e=6.84×10(-6) cm s(-1)),具有较低的细胞毒性以及良好的物化性质,因此,化合物6.22可以进一步开发为一种潜在多功能神经保护剂。(C)2019 Elsevier Masson SAS. 版权所有。

Pre-treatment with &agr;,&bgr; unsaturated aryl sulfones protects normal cells from the cytotoxic side effects of two classes of anticancer chemotherapeutics. Administration of a cytoprotective sulfone compound to a patient prior to anticancer chemotherapy with a mitotic phase cell cycle inhibitor or topoisomerase inhibitor reduces or eliminates the cytotoxic side effects of the anticancer agent on normal cells. The cytoprotective effect of the &agr;,&bgr; unsaturated aryl sulfone allows the clinician to safely increasing the dosage of the anticancer chemotherapeutic.

Pre-treatment with &agr;,&bgr; unsaturated aryl sulfones protects normal cells from the toxic side effects of ionizing radiation. Administration of a radioprotective &agr;,&bgr; unsaturated aryl sulfone compound to a patient prior to anticancer radiotherapy reduces the cytotoxic side effects of the radiation on normal cells. The radioprotective effect of the &agr;,&bgr; unsaturated aryl sulfone allows the clinician to safely increase the dosage of anticancer radiation. In some instances, amelioration of toxicity following inadvertent radiation exposure may be mitigated with administration of &agr;,&bgr; unsaturated arylsulfone.
