The reactions of 2-bromobenzimidazole, 2-bromo-5-chlorobenzimidazole or 6-bromopyridin-2(1H)-one as the starting heterocyclic compounds with the aminomethyloxiranes were performed. The following amines: indoline, morpholine, and N-phenylpiperazine derivatives were chosen. The final products contained oxazole ring fused to an appropriate heterocyclic compound. The cyclic amide pyridin-2(1H)-one is subjected to lactam-lactim tautomerism, whereby an additional product containing 2-hydroxypropoxy fragment was formed. For the final compounds, pharmacological tests were performed to determine their inhibition of the phosphodiesterase activity, the affinity towards adrenergic and serotoninergic receptors. Additionally, anti/mutagenic and hypotensive activity for selected compounds with the best α1-adrenoceptor affinity (Ki < 160 nM) was tested. The results have shown that the studied compounds characterized antimutagenic properties in the Vibrio harveyi test and hypotensive activity in normotensive rats. Furthermore, the lipophilicity of the investigated compounds was assessed experimentally and in silico.}, title={Synthesis and studies of reaction products of oxirane derivatives with heterocycles containing −NH−(C=)−Br functionality as potential cardiovascular agents}, type={Praca doktorska}, keywords={N-arylpiperazine derivatives, pyridin-2(1H)-one, alfa1-adrenoceptors, benzimidazole, phosphodiesterase}, }
