摘要：

设计合成了一系列以嘧啶联苯为中心结构的潜在激酶变构抑制剂. 以2,4-二氯-5-甲基嘧啶为起始原料, 通过Suzuki偶联一锅法合成了中心药效团嘧啶联苯, 通过X射线单晶衍射分析确认结构, 并在此基础上衍生化合成了19个化合物. 采用噻唑蓝(MTT)法对所得化合物用人乳腺癌细胞(MCF-7)进行体外抗肿瘤活性初步筛选, 并找到2个具有潜在应用价值的化合物8c(IC₅₀=0.224 μmol/L)和9c(IC₅₀=0.113 μmol/L).

Abstract:

Allosteric kinase inhibitors modulate kinase activities by inducing and stabilizing the inactive conformations of the targets. In comparison to ATP competitive inhibitors, this type inhibitors exhibit better selectivity and higher efficacy, and have shown to be safe and effective treatments for various forms of cancers in the clinics. Based on the X-ray co-crystal structures of reported allosteric kinase inhibitors bound to thecorresponding protein kinases, a bi-cyclic pharmacophore model was proposed. 19 new phenylpyrimidine derivatives were designed and synthesized from 2,4-diamino-5-methylpyrimidine. The inhibitory effects of these compounds against human breast cancer cell(MCF-7) proliferation were evaluated using MTT method. The leader compounds, 8c and 9c, were identified showing IC₅₀ of 0.224 and 0.113 μmol/L, respectively.
