The fundamental role that receptor tyrosine kinases play in cancer and other proliferative diseases has provided the impetus for an extensive effort on the part of both academic and pharmaceutical laboratories to develop highly specific inhibitors. In this study, inhibitory activity of previously synthesized arylacetic and arylcarboxylic acid derivatives were examined against substrate of tyrosine kinase. It can be assumed that the activity of compounds becomes higher when the –CH2 linkage exist between aromatic ring and the amide group of the side chain. In addition, when the R1 and R2 substitutents are methyl group in both series, the higher activity observed. The data obtained from docking study (DOCK4.0) indicated that compounds 2, 4, 7, 8, 11 render satisfactory interaction with the active site of enzyme, Lys295 of p60c-Src tyrosine kinase. Comparison of this interaction and the evaluation of biological data showed that compound 4 is the most active among the entire derivatives.
受体酪氨酸激酶在癌症和其他增殖性疾病中扮演着重要角色,这推动了学术界和制药实验室开发高度特异性抑制剂的广泛努力。本研究考察了以前合成的芳基乙酸和芳基羧酸衍生物对酪氨酸激酶底物的抑制活性。可以推测,当芳香环和侧链的酰胺基之间存在 -CH2 连接时,化合物的活性会更高。此外,当两个系列中的 R1 和 R2 取代基都是甲基时,观察到的活性也更高。对接研究(DOCK4.0)获得的数据表明,化合物 2、4、7、8 和 11 与 p60c-Src 酪氨酸激酶的 Lys295 酶活性位点的相互作用令人满意。这种相互作用与生物数据评估的比较表明,化合物 4 是所有衍生物中活性最高的。
