Seeking for new anticancer drugs with strong antiproliferative activity and simple molecular structure, we designed a novel series of compounds based on our previous reported pharmacophore model composed of five moieties. Antiproliferative assays on four tumoral cell lines and evaluation of Human Choline Kinase CKα1 enzymatic activity was performed for these compounds. Among tested molecules, those
为了寻找具有强抗增殖活性和简单分子结构的新抗癌药物,我们根据先前报道的由五个部分组成的药效团模型设计了一系列新型化合物。对这些化合物进行了四种肿瘤细胞系的抗增殖测定和人胆碱激酶CKα1酶活性的评估。在测试的分子中,那些具有联苯间隔基的分子表现出更好的酶促和抗增殖活性(nv)。对接和结晶研究验证了该假设并确认了结果。最活跃的化合物(吨)诱导了G0 / G1期细胞周期的明显停滞,最终导致了线粒体途径后的细胞凋亡,正如其他胆碱激酶抑制剂所证明的那样。然而,另外的测定表明,胆碱摄取的抑制也可能与这类化合物的抗增殖结果有关。
