A series of N-(3-(4-(pyridin-3-yl)-1H-imidazol-2-ylamino)phenyl)amides were synthesized and tested for inhibition of PDGFR and FLT3 autophosphorylation. The novel N-(3-(4-(pyridin-3-yl)-1H-imidazol-2-ylamino)phenyl)amides, obtained by replacement of the pyrimidine system in Imatinib (1) with an imidazole ring, exhibit potent inhibitory activity on PDGFR, similar to the parent compound (IC(50) (9e)=0
合成了一系列N-(3-(4-(吡啶-3-基)-1H-咪唑-2-基氨基)苯基)酰胺,并测试了其对PDGFR和FLT3自磷酸化的抑制作用。通过用咪唑环取代伊马替尼(1)中的嘧啶系统而获得的新型N-(3-(4-(吡啶-3-基)-1H-咪唑-2-基氨基)苯基)酰胺具有强抑制作用与母体化合物相似(IC(50)(9e)= 0.2 microM; IC(50)伊马替尼(1)= 0.3 microM)。如对FLT3(一种密切相关的III类受体酪氨酸激酶)没有活性所显示的,其似乎似乎是保守的,其不受母体化合物伊马替尼的影响。
