A series of novel thiazolo derivatives 2–17 were synthesized by initial condensation of methyl2-(thiazol-2-ylcarbamoyl)acetate 1 with phenyl isothiocyanate and further reactions using different organic reagents. The structures of newly synthesized compounds were confirmed by IR, 1H NMR, EIMS spectral data and elemental analysis. Initially the acute toxicity of the compounds was assayed via the determination
一系列新颖的噻唑并衍生物2 - 17由2-(噻唑-2-基氨基甲酰基)乙酸酯的初始缩合合成1用不同的有机试剂异硫氰酸苯酯和进一步的反应。通过IR,1 H NMR,EIMS光谱数据和元素分析确认了新合成的化合物的结构。最初,化合物的急性毒性是通过确定其LD 50来测定的。筛选所有化合物的抗心律不齐和抗凝活性,与普鲁卡因酰胺和利多卡因作为阳性对照相比,它们显示出较高的抗心律不齐活性。详细的合成,光谱数据,LD 50 并报道了合成化合物的药理活性。
