previously reported that thieno[2,3-d]pyrimidine derivative compound 1 exhibited better antiproliferative activity against MV4-11 cells which harbor mutant FLT3 than AC220, which is a well-known FLT3 inhibitor, and has good microsomal stability. However, compound 1 had poor solubility. We then carried out further structural modification at the C2 and the C6 positions of thieno[2,3-d]pyrimidine scaffold
急性髓细胞性白血病(AML)是造血祖细胞的克隆性疾病。在AML中,通常会发生FLT3突变,并与不良预后相关。先前我们已经报道了噻吩并[2,3- d ]嘧啶衍生物化合物1对具有突变型FLT3的MV4-11细胞表现出比AC220更好的抗增殖活性,AC220是众所周知的FLT3抑制剂,并且具有良好的微粒体稳定性。但是,化合物1的溶解性差。然后,我们在噻吩并[2,3- d ]嘧啶骨架的C 2和C 6位置进行了进一步的结构修饰。化合物13b在化合物C 2位置具有噻唑部分的化合物,比化合物1表现出更好的抗增殖活性,并显示出更高的溶解度和适度的微粒体稳定性。这些结果表明,化合物13b可能是用于AML化学疗法的有前途的潜在FLT抑制剂。
