背景:CDK2作为细胞生长的控制者显示出基本的作用,这使其成为抗癌抑制剂的目标之一。 方法:目前的研究参与了设计(对接和结合能)研究,该研究用于选择有希望的拟议化合物,合成多种新颖的14种吡啶并[2,3-d]嘧啶衍生物,并对制备的化合物作为有前途的抗癌药进行生物学研究。瞄准CDK2。扫描所有新鲜产生的化合物对MCF-7和CaCO2的抗癌活性,发现14种化合物具有活性。化合物6c和8d在MCF-7上显示出IC50分别为7.4和5.5的表达活性。将产生的化合物进行酶检查(CDK2),以指定其抑制活性。 结果:初步结果表明,化合物8d具有很强的抑瘤活性,对CDK2酶有很强的抑制作用(89%抑制作用),可以用作候选化合物。产物通过IR,1 H NMR,13 C NMR和MS表征。 结论:初步生物测定表明,大多数化合物具有很好的抗肿瘤活性和对CDK2酶的强抑制作用。
Tyrphostins I: synthesis and biological activity of protein tyrosine kinase inhibitors
摘要:
A novel class of low molecular weight protein tyrosine kinase inhibitors is described. These compounds constitute a systematic series of molecules with a progressive increase in affinity toward the substrate site of the EGF receptor kinase domain. These competitive inhibitors also effectively block the EGF-dependent autophosphorylation of the receptor. The potent EGF receptor kinase blockers examined were found to competitively inhibit the homologous insulin receptor kinase at 10(2)-10(3) higher inhibitor concentrations in spite of the significant homology between these protein tyrosine kinases. These results demonstrate the ability to synthesize selective tyrosine kinase inhibitors. The most potent EGF receptor kinase inhibitors also inhibit the EGF-dependent proliferation of A431/clone 15 cells with little or no effect on EGF independent cell growth. These results demonstrate the potential use of protein tyrosine kinase inhibitors as selective antiproliferative agents for proliferative diseases caused by the hyperactivity of protein tyrosine kinases. We have suggested the name "tyrphostins" for this class of antiproliferative compounds which act as protein tyrosine kinase blockers.
