target for the treatment of non-small cell lung cancer. As an emerging element in medicinal chemistry, boron has achieved great success in the discovery of antitumor drugs and antibacterial agents. Through construction of a BCC (boron-containing compound) compound library and broad kinase screening, we found the ALK inhibitor hit compound 10a. Structural optimization by CADD and isosterism revealed that
ALK 是治疗非小细胞肺癌的一个有吸引力的治疗靶点。硼作为药物化学的新兴元素,在抗肿瘤药物和抗菌药物的发现方面取得了巨大成功。通过构建BCC(含硼化合物)化合物库和广泛的激酶筛选,我们发现了ALK抑制剂命中化合物10a 。通过 CADD 和等排现象进行的结构优化表明,先导化合物10k具有更高的活性(ALK L1196M IC 50 = 8.4 nM,NCI-H2228 细胞 IC 50 = 520 nM)和更好的体外代谢稳定性(人肝微粒体,T 1/2 = 238)分钟)。化合物10k在裸鼠NCI-H2228肺癌异种移植模型中表现出良好的体内疗效,TGI为52%。分子模拟分析结果表明,氧杂硼杂环戊烯上的羟基与Asn1254或Asp1270形成关键的氢键,该结合位点为药物设计提供了新的思路。这是第一个公开报道的含硼 ALK 抑制剂的先导化合物。
