Discovery of N -(5-((5-chloro-4-((2-(isopropylsulfonyl)phenyl)amino)pyrimidin-2-yl)amino)-4-methoxy-2-(4-methyl-1,4-diazepan-1-yl)phenyl)acrylamide (CHMFL-ALK/EGFR-050) as a potent ALK/EGFR dual kinase inhibitor capable of overcoming a variety of ALK/EGFR associated drug resistant mutants in NSCLC
摘要:
Recently, more and more concomitant EGFR mutations and ALK rearrangement are observed from the clinic, which still lacks effective single-agent therapy, Starting from ALK inhibitor 14 (TAE684), we have developed a highly potent EGFR/ALK dual kinase inhibitor compound 18 (CHMFL-ALK/EGFR-050), which potently inhibited EGFR L858R, del 19 and T790M mutants as well as EML4-ALK, R1275Q L1196M, F1174L and C1156Y mutants biochemically. Compound 18 significantly inhibited the proliferation of EGFR mutant and EML4-ALK driven NSCLC cell lines. In the cellular context it strongly affected EGFR and ALK mediated signaling pathways, induced apoptosis and arrested cell cycle at G0/G1 phase. In the in vivo studies, 18 significantly suppressed the tumor growth in H1975 cell inoculated xenograft model (40 mg/kg/d, TGI: 99%) and H3122 cell inoculated xenograft model (40 mg/kg/d, TGI: 78%). Compound 18 might be a potential drug candidate for EGFR- or ALK-individual as well as concomitant EGFR/ALK NSCLC. (C) 2017 Elsevier Masson SAS. All rights reserved.
组织蛋白酶 C (Cat C) 通过影响中性粒细胞丝氨酸蛋白酶 (NSP) 的激活参与炎症和免疫调节。因此,组织蛋白酶 C 是治疗 NSP 相关炎症性疾病的一个有吸引力的靶点。在此,从命中发现、结构优化和先导化合物发现三个方面描述了第一个强效“非肽基非共价组织蛋白酶C抑制剂”的完整发现过程。从hit 14开始,全面开展了基于结构的优化和构效关系研究,发现先导化合物54在体内和体外均是一种有效的类药组织蛋白酶C抑制剂。此外,化合物54 (与组织蛋白酶 C Enz IC 50 = 57.4 nM)在慢性阻塞性肺病动物模型中表现出有效的抗炎活性。这些结果证实了非肽基和非共价衍生物可以用作有效的组织蛋白酶C抑制剂,并鼓励我们在此发现的基础上继续进一步的药物发现。
