With ceritinib as the lead, a series of novel compounds containing the sulfoxide structure were synthesized and evaluated as anaplastic lymphoma kinase inhibitors. Among them, compounds 18a–d exhibited excellent anti-proliferation activities on H2228 EML4-ALK cancer cell lines with 14–28 nM of the IC50 values. In xenograft mouse models, 18a–d inhibited tumor growth with an excellent inhibitory rate
以色瑞替尼为主导,合成了一系列含有亚砜结构的新型化合物,并对其作为间变性淋巴瘤激酶抑制剂进行了评价。其中,化合物18a-d对H2228 EML4-ALK癌细胞系表现出优异的抗增殖活性,IC 50值为14-28 nM。在异种移植小鼠模型中, 18a-d在 20 mg kg -1剂量下抑制肿瘤生长,抑制率为 75.0% 至 86.0%,而参考色瑞替尼的抑制率为 72.0%。以体内效果最好的18d为代表,我们开展了抗集落形成、诱导肿瘤细胞凋亡、H2228肿瘤细胞中ALK激酶蛋白磷酸化、分子对接等机制研究。所有这些结果表明化合物18d是一种良好的抗肿瘤先导化合物,值得进一步研究。
