quinoline derivatives for their antiproliferative activities. Preliminary docking studies indicated that these ligands had the ability to bind to two of the serotonin receptors, 5-HT1B and 5-HT2B. The results of the in silico experiments were validated by performing in vitro studies on MCF-7 breast cancer cell line. The ethylpiperazine derivatives showed maximum toxicity against this cancer cell line. The
信号受体的拮抗剂通常是有效的无毒治疗剂。多年来,已有证据描述5-羟色胺或5-羟色胺(5-HT)在癌症发展中的作用。尽管有关于某些5-羟色胺受体拮抗剂的抗增殖作用的报道,但很少有与了解它们的结构-活性关系有关的研究。在这项研究中,我们报告了针对其抗增殖活性的4-苯基喹啉衍生物文库的筛选。初步的对接研究表明,这些配体具有结合5-羟色胺受体中的两种的能力,即5-HT 1B和5-HT 2B。通过体外验证来验证计算机模拟实验的结果MCF-7乳腺癌细胞系的研究。乙基哌嗪衍生物显示出对该癌细胞系最大的毒性。该化合物抑制钙离子外流(由5-羟色胺诱导)和ERK活化。活性最高的4-苯基喹啉衍生物(H3a)之一也诱导凋亡,从而表明该支架可用作潜在的抗癌药物。
