Design, synthesis and biological evaluation of 2-arylaminopyrimidine derivatives bearing 1,3,8-triazaspiro[4,5]decan-4-one or piperidine-3-carboxamide moiety as novel Type-I1/2 ALK inhibitors
摘要:
Aiming to develop novel Type -I-1/2 inhibitors of ALK to overcome extensive resistance mutations, especially the L1196M mutation surrounding the ATP pocket, two series of 2-arylaminopyrimidine derivatives (11a-f and 22at) were designed based on scaffold hopping. The extensive structural elaboration discovered compound 22o which possessed excellent IC50 values of 0.06 and 0.23 mu M against ALK-positive Karpas299 and H2228 cell lines, respectively. Meanwhile, 22o displayed encouraging inhibitory potency in the ALK(WT) (2.5 nM) and ALK(L1196m )(6.5 nM) enzymatic assays. Furthermore, the AO/EB and Hoechst 33258 assays illustrated 22o could induce cell apoptosis in a dose-dependent manner. Eventually, the molecular docking of 22o with ALK clearly presented the vital interactions within the active site, which was in accordance with Type -I-1/2 inhibitor binding mode.

The present invention relates to compounds comprising an interleukin-1 receptor-associated kinase 1 (IRAK1) protein binding moiety and a Von Hippel-Lindau (VHL) E3 ubiquitin ligase binding moiety, and associated methods of use. The compounds are useful as modulators of targeted ubiquitination, especially with respect to IRAK1, which is degraded by the compounds according to the invention.
The present invention relates to compounds of formula (I), wherein R, R, Ar, W, X and Z are all as defined herein. The compounds of the present invention are known to inhibit the spindle checkpoint function of Monospindle 1 (Mps1 – also known as TTK) kinases either directly or indirectly via interaction with the Mps1 kinase itself. In particular, the present invention relates to the use of these compounds as therapeutic agents for the treatment and/or prevention of proliferative diseases, such as cancer. The present invention also relates to processes for the preparation of these compounds, and to pharmaceutical compositions comprising them.
myeloid leukemia (AML) cases and confer a poor prognosis. Optimization of the screening hit 1 from our in-house compound library led to the discovery of a series of pyrazolo[1,5-a]pyrimidine derivatives as potent and selective FLT3-ITD inhibitors. Compounds 17 and 19 displayed potent FLT3-ITD activities both with IC50 values of 0.4 nM and excellent antiproliferative activities against AML cell lines. Especially
FLT3 的内部串联重复 (FLT3-ITD) 发生在大约 25% 的所有急性髓性白血病 (AML) 病例中,并且预后不良。我们内部化合物库中筛选命中1的优化导致发现了一系列吡唑并[1,5 - a ]嘧啶衍生物作为有效和选择性的 FLT3-ITD 抑制剂。化合物17和19显示出有效的 FLT3-ITD 活性,IC 50值为 0.4 nM,并且对 AML 细胞系具有优异的抗增殖活性。特别是化合物17和19抑制了 quizartinib 的耐药性—— 赋予突变FLT3 D835Y,两者都具有0.3 nM的IC 50值。此外,蛋白质印迹分析表明化合物17和19有效抑制了 FLT3 的磷酸化并减弱了 AML 细胞中的下游信号传导。这些结果表明吡唑并[1,5 - a ]嘧啶衍生物可能是治疗AML的有前途的FLT3-ITD抑制剂。
