The compound “2-((4-nitrophenyl)amino)-7,8,9,10-tetrahydro cyclohepta[4,5]thieno[2,3-d][1,3,4]thiadiazolo[3,2-a]pyrimidin-11(6H)-one” and method of synthesizing it, wherein the compound is effective to inhibit the growth and proliferation of human liver cancer cells HepG2. The compound has a higher efficiency to inhibit the growth and proliferation of these cells as it has an inhibitory concentration value (IC
50
) of 0.7 μg, compared to reference medication Doxorubicin that has an (IC
50
) value of 1.2 μg. It further surpasses that reference medication at all tested concentrations. The method includes the steps of: preparing a first compound of cycloheptanone, ethylcyanoacetate, sulfur, ethanol and diethylamine; preparing a second compound by heating of the first compound with excess of hydrazine hydrate in absolute ethanol as solvent; preparing a third compound by heating the second compound with carbon disulphide in dry pyridine; and preparing the compound of the invention by reacting the third compound with 4-nitrophenylisothiocyanate in dry N,N-methylformamide as solvent.
这个化合物是“2-((4-硝基苯基)氨基)-7,8,9,10-四氢环庚并[4,5]噻吩[2,3-d][1,3,4]噻二唑并[3,2-a]嘧啶-11(6H)-酮”,以及合成它的方法,其中这个化合物有效地抑制人类肝癌细胞HepG2的生长和增殖。与参考药物多柔比星(Doxorubicin)的IC50值为1.2μg相比,该化合物具有更高的效率来抑制这些细胞的生长和增殖,其IC50值为0.7μg。它在所有测试浓度下进一步超越了参考药物。该方法包括以下步骤:制备环庚酮、乙基氰乙酸酯、硫、乙醇和二乙胺的第一化合物;通过在绝对乙醇中用过量的水合肼加热第一化合物制备第二化合物;通过在干燥吡啶中用二硫化碳加热第二化合物制备第三化合物;通过在干燥N,N-甲基甲酰胺中用4-硝基苯基异硫氰酸酯与第三化合物反应制备该发明的化合物。
