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.

A series of new 2-ary loxymethy loxiranes prepared from epichlorohydrin and substituted phenols was subjected to nucleophilic opening of the oxirane ring. A comparison of regioselectivity and product yield for oxirane cleavage by means of aqueous hydrohalogenic acids or lithium tetrahalogenocuprates under anhydrous conditions was performed. The latter method provided very high regioselectivity for 3-aryloxy-l-halo-genopropan-2-ols as well as excellent yields.
