Src kinase mutations and/or overexpression have been implicated in the development of a number of human cancers including colon, breast, and lung cancers. Thus, designing potent and selective Src kinase inhibitors as anticancer agents is a subject of major interest. A series of 4-aryl substituted derivatives of 2-amino-7-dimethylamino-4H-chromene- 3-carbonitrile were synthesized using one-pot reaction of appropriate substituted aromatic aldehydes, malononitrile, and 3-(dimethylamino)phenol in the presence of piperidine. All 23 compounds were evaluated for inhibition of Src kinase and cell proliferation in human colon adenocarcinoma (HT-29) and leukemia (CCRF-CEM) cell lines. Among the tested compounds, 2-chlorophenyl- (4c), 3-nitrophenyl- (4h), 4-trifluoromethyphenyl- (4i), and 2,3-dichlorophenyl- (4k) substituted chromenes showed Src kinase inhibitory effect with IC50 values of 11.1-18.3 μM. Compound 4c was relatively selective against Src (IC50 = 11.1 μM), when compared with selected kinases, epidermal growth factor receptor (EGFR, IC50 300 μM), C-terminal Src kinase (Csk, IC50 = 101.7 μM), and lymphocyte-specific protein tyrosine kinase (Lck, IC50 = 46.8 μM). 3-Chlorophenyl substituted thiazole (4v) and 2-chlorophenylsubstituted thiazole (4u) chromene derivatives inhibited the cell proliferation of HT-29 and CCRF-CEM by 80% and 50%, respectively, at a concentration of 50 μM. The data indicate that 4H-chromene-3-carbonitrile scaffold has the potential to be optimized further for designing more potent Src kinase inhibitors and/or anticancer lead compounds.
Src 激酶突变和/或过度表达与结肠癌、乳腺癌和肺癌等多种人类癌症的发病有关。因此,设计强效且具有选择性的 Src 激酶抑制剂作为抗癌药物是一个备受关注的课题。在哌啶的存在下,利用适当取代的芳香醛、丙二腈和 3-(二甲基氨基)苯酚的一锅反应,合成了一系列 2-amino-7-dimethylamino-4H-chromene- 3-carbonitrile 的 4-芳基取代衍生物。对所有 23 种化合物在人结肠腺癌(HT-29)和白血病(CCRF-CEM)细胞系中对 Src 激酶和细胞增殖的抑制作用进行了评估。在测试的化合物中,2-氯苯基(4c)、3-硝基苯基(4h)、4-三氟甲基苯基(4i)和 2,3-二氯苯基(4k)取代的色烯类化合物具有抑制 Src 激酶的作用,IC50 值为 11.1-18.3 μM。与选定的激酶、表皮生长因子受体(EGFR,IC50 300 μM)、C-末端 Src 激酶(Csk,IC50 = 101.7 μM)和淋巴细胞特异性蛋白酪氨酸激酶(Lck,IC50 = 46.8 μM)相比,化合物 4c 对 Src 具有相对的选择性(IC50 = 11.1 μM)。3-氯苯基取代的噻唑(4v)和 2-氯苯基取代的噻唑(4u)色烯衍生物在 50 μM 浓度下分别抑制 HT-29 和 CCRF-CEM 细胞增殖 80% 和 50%。这些数据表明,4H-色烯-3-甲腈支架具有进一步优化的潜力,可用于设计更有效的 Src 激酶抑制剂和/或抗癌先导化合物。
