approach utilizing readily accessible building blocks and (b) a divergent approach based on a microwave heating assisted Suzuki coupling. We established a chromatography-free purification method to generate products with sufficient purity for the biological assays. The structure–activity relationship of the library provided the rationale for the synthesis of the benzothiazolylurea 66 (IC50 = 140 nM) and the
糖原合酶激酶3(GSK-3)参与多个细胞过程,并已与阿尔茨海默氏病(AD)的发病机理有关。在我们的研究主题过程中,我们合成了有效的GSK-3抑制剂库。我们利用了有效且高度选择性的GSK-3抑制剂AR-A014418(AstraZeneca)中存在的尿素支架。该部分既适合(a)利用易于获得的构件的收敛方法,又适合(b)基于微波加热辅助的Suzuki耦合的发散方法。我们建立了无色谱纯化方法,以产生具有足够纯度的生物测定产物。文库的构效关系为合成苯并噻唑基脲66(IC 50 在我们的测定中 ,其活性为 140 nM)和吡啶基脲62(IC 50 = 98 nM),与参考化合物18(AR-A014418:IC 50 = 330 nM)相比,其活性提高了2到3倍。
