previously unobserved inhibitor/activator activity profile against protein acetyltransferases. Herein, we report that manipulation of the carbonyl functions of a series of analogues of SPV106 yielded different activity profiles against KAT2B and KAT3B (pure KAT2B activator, pan‐inhibitor, or mixed KAT2B activator/KAT3B inhibitor). Among the novel compounds, a few derivatives may be useful chemical tools
赖氨酸乙酰基转移酶(KATs)活性的异常调节与多种疾病和/或病理性细胞状态有关。但是,它们的作用仍不清楚。因此,开发这些酶的选择性调节剂至关重要,因为这些分子可能是评估KAT在几种病理中的重要性的宝贵工具。我们最近发现,戊二烯丙二酸二乙酯(SPV106)具有以前未观察到的针对蛋白质乙酰转移酶的抑制剂/活化剂活性特征。在本文中,我们报道了一系列SPV106类似物的羰基功能操纵产生了针对KAT2B和KAT3B(纯KAT2B激活剂,泛抑制剂或混合的KAT2B激活剂/ KAT3B抑制剂)的不同活性谱。在新化合物中,
