The goal of this study was to develop novel radioprotective agents targeting the intrinsic apoptotic pathway and thus decreasing the radiation-induced damage. For that purpose, we designed, synthesized and analyzed ten new compounds based on the 1-(4-(2-hydroxyethyl)piperazin-1-yl)-3-phenoxypropan-2-ol leading structure. The cytotoxicity of the newly synthesized substances was tested in vitro on cell lines derived from different progenitor cells by WST-1 proliferation assay. MTT test was utilized to assess half-maximal inhibitory concentrations and maximum tolerated concentrations of novel compounds in A-549 cells. Screening for radioprotective properties was performed using flow-cytometry in MOLT-4 cells exposed to 60Co ionizing gamma radiation. Selected candidates underwent in vivo testing in C57Bl/6 J mice having a positive impact on their immunological status. In summary, we report here promising compounds with radioprotective effect in vivo.

具有辐射防护性质的新型小分子抑制剂。

这项研究的目的是开发针对内在的细胞凋亡途径的新型放射防护剂,从而减少辐射引起的损害。为此,我们设计,合成和分析了基于1-(4-(2-羟乙基)哌嗪-1-基)-3-苯氧基丙烷-2-醇前导结构的十个新化合物。通过WST-1增殖试验,在不同祖细胞衍生的细胞系上体外测试了新合成物质的细胞毒性。使用MTT试验评估A-549细胞中新化合物的半数最大抑制浓度和最大耐受浓度。使用流式细胞仪在暴露于60Co电离γ射线的MOLT-4细胞中进行放射防护性能的筛选。选定的候选者在C57Bl / 6 J小鼠中进行了体内测试,对其免疫状况产生了积极影响。总而言之,我们在这里报告了在体内具有放射防护作用的有前途的化合物。
