在本研究中,我们着手基于吡唑并[3,4- d ]嘧啶支架合理优化PKD抑制剂。本研究的先导化合物是 1-NM-PP1,我们和其他人之前发现它可以抑制 PKD。在我们的筛选中,我们鉴定出一种化合物 (3-IN-PP1),其效力比 1-NM-PP1 提高 10 倍,为对吡唑并显示敏感性的激酶的特定蛋白激酶抑制剂开辟了新的可能性[3,4- d ]嘧啶衍生的化合物。有趣的是,观察到的 SAR 与通常观察到的结合模式并不完全一致,其中吡唑并[3,4- d ]嘧啶化合物以与 PKD 天然配体 ATP 类似的方式结合。因此,我们建议采用另一种结合模式,其中化合物翻转 180 度。这种基于吡唑并[3,4- d ]嘧啶的化合物的可能的替代结合模式可以为用于对吡唑并[3,4- d ]嘧啶敏感的激酶的新型特异性蛋白激酶抑制剂铺平道路。
Phospholipase D enzymes cleave lipid substrates to produce phosphatidic acid, an important precursor for many essential cellular molecules. Phospholipase D is a target to modulate cancer‐cell invasiveness. This study reports synthesis of a new class of phospholipase D inhibitors based on 1,3‐disubstituted‐4‐amino‐pyrazolopyrimidine core structure. These molecules were synthesized and used to perform initial
