New N-substituted amides of 3-(3-ethylthio-1,2,4-triazol-5-yl)propenoic acid (2–12) were designed and prepared by the condensation reaction of exo-S-ethyl-7-oxabicyclo-[2.2.1]-hept-5-ene-2,3-dicarbonyl isothiosemicarbazide (1) with primary amines. The chemical structure of all compounds was confirmed by IR, 1H NMR, 13C NMR spectra, the X-ray crystallography (for compounds 8, 11, 12) and elemental analysis
新Ñ取代的酰胺3-(3-乙硫基-1,2,4-三唑-5-基)丙烯酸(2 - 12),设计并通过的缩合反应制备的外切-小号-乙基-7-氧杂双环-[2.2.1]-庚-5-烯-2,3-二羰基异硫代氨基脲(1)与伯胺。所有化合物的化学结构用IR确认,1 H NMR,13 C NMR光谱,X-射线晶体学(对于化合物8,11,12)和元素分析。 此外,化合物9 - 11筛选了抗癌活性。发现化合物9(浓度为0.32 mM和0.16 mM),化合物10(浓度为0.28 mM和0.14 mM)和11(浓度为0.35 mM和0.17 mM)在体外对肺细胞系有效( IC50)。确定了化合物9和10在体外乳腺癌细胞中具有明显标记的抗增殖作用。此外,浓度为0.16 mM和0.03 mM的化合物9对正常皮肤成纤维细胞系和乳腺癌细胞的最低细胞毒性在这项研究中,在孵育24小时和48小时后,我们发现了在体外。
