tyrosine kinase 3 (FLT3) is always overexpressed in many cases of acute leukemia. This paper studies the structure-based synthesis and biological evaluation of diaryl urea derivatives as FLT3 inhibitors. Encouragingly, compounds 15b, 16b, 24a, and 24c showed excellent biological activities in a low nanomolar range. In particular, compound 16b demonstrated significant inhibitory potency against FLT3-ITD
作为III类受体
酪氨酸激酶(RTK),
FMS样
酪氨酸激酶3(FLT3)在许多急性白血病病例中总是过表达。本文研究了二芳基
脲衍
生物作为FLT3
抑制剂的结构化合成和
生物学评价。令人鼓舞的是,化合物15b,16b,24a和24c在低纳摩尔范围内显示出出色的
生物活性。特别地,化合物16b表现出对FLT3-ITD的显着抑制作用(IC 50= 5.60nM),并且比奎扎替尼对MV4-11
细胞系具有更好的抗增殖活性(IC 50=0.176nM )。表明化合物16b 对于急性髓细胞白血病的治疗可能非常有前途。
