Novel 2,4-Dianilinopyrimidine-based Aurora-A kinase (AURKA) degraders are disclosed. The present AURKA degraders are proteolysis targeting chimeras (PROTACs) that recruit AURKA protein into optimized CRBN E3 ubiquitin ligase via linkers. The compounds may induce selective AURKA degradation and may be utilized for the treatment of cancer.

compound 10a. Flow cytometric analysis on both MCV-7 and PC-3 cancer cells revealed that it induced cell-cycle arrest in the G0-G1phase and reinforced apoptosis via activation of caspase-3. Furthermore, molecular modeling studies have been carried out to gain further understanding of the binding mode in the active site of VEGFR-2 enzyme and predict pharmacokinetic properties of all the synthesized inhibitors
设计,合成和评价了不同系列的新型噻吩并[2,3- d ]嘧啶衍生物(9a-d,10a-f,l,m和15a-m)在体外抑制VEGFR-2酶的能力。而且,通过NCI对60种不同的人类癌细胞系进行了测试,以测试最终化合物的细胞毒性。VEGFR-2酶的抑制结果表明,化合物10d,15d和15 g是活性最高的抑制剂,IC 50值分别为2.5、5.48和2.27 µM,而化合物10a显着显示出最高的细胞生长抑制率,平均生长抑制率(GI)为31.57%。它对几种NCI细胞系表现出广谱的抗增殖活性,特别是对人乳腺癌(T7-47D)和肾癌(A498)细胞系分别具有85.5%和77.65%的抑制作用。为了研究该活性的机制,对化合物10a进行了进一步的生物学研究,例如流式细胞术细胞周期与caspase-3比色测定。对MCV-7和PC-3癌细胞的流式细胞仪分析表明,它诱导了G0-G1期的细胞周期停滞,并通过激活c

oquinazoline derivatives bearing diarylamide moiety were designed, synthesized and evaluated as potent inhibitors of VEGFR-2kinase. Their in vitro antiproliferation activities against two human cancer cell lines Hep-G2 and MCF-7 have also been determined. Among them, compound 14b exhibited the most potent inhibitory activity against VEGFR-2 with IC50 value of 0.016 ± 0.002 µM and it showed the most
