lung squamous cell carcinoma to design multi-target inhibitors represents a potential strategy for the medical treatment. In this study, through screening an in-house focused library, we identified an interesting indazole scaffold. And following with binding analysis, we elaborated the structure-activity relationship of this hit compound by optimizing four parts guided by the DDR2 enzymatic assay, which
尽管肺腺癌患者受益于靶向治疗的发展,但肺鳞癌(SqCC)患者由于该疾病的复杂性和异质性而无法有效治疗。因此,基于对肺鳞状细胞癌突变的遗传分析以设计多靶点抑制剂代表了一种潜在的治疗策略。在这项研究中,通过筛选内部聚焦库,我们确定了一种有趣的吲唑支架。然后进行结合分析,我们通过优化DDR2酶测定法指导的四个部分,详细阐述了这种命中化合物的结构-活性关系,从而得到了有效的先导化合物10a。。我们进一步优化了针对肺鳞状细胞癌中两个重要激酶FGFR1和DDR2的双重酶促抑制作用。最后,从细胞抗增殖活性测试和体内药代动力学测试中,发现3-取代的吲唑衍生物11k是很有前途的候选者,并通过小鼠异种移植模型进行了体内药理学研究,证明了其强大的抗肿瘤功效。额外的体外药物样评估进一步证明了化合物11k对于SqCC药物开发可能是有价值的。
