基于强大的K v 7激动剂RL-81,我们制备了新的铅结构,在相关钾通道上对K v 7.2 / K v 7.3的选择性大大提高,即K v 7.3 / K v 7.5,K v 7.4和K v 7.4 / 7.5。RL-36和RL-12保持的激动剂EC 2 X约的 在自动电生理平台上的HEK293细胞中的高通量测定中,在K v 7.2 / K v 7.3上为1μM,但在K v 7.3 / K v 7.5,K v 7.4和K v上没有活性7.4 / 7.5,导致选择性指数SI> 10。RL-56非常有效,EC 2 x 0.11±0.02μM,仍然显示SI = 2.5。我们还确定了对K v 7.4 / K v 7.5相对于K v 7.2 / K v 7.3具有显着选择性的类似物。氟在迭代核心结构修饰中的广泛使用突显了这些取代基(包括F,CF 3和SF 5)的多功能性,可跨越药物化学铅优化中效价和选择性的数量级。
Selective potassium channel agonists and methods of use thereof are disclosed. A compound, or a pharmaceutically acceptable salt thereof, having a formula (I) wherein R1 is H or optionally-substituted alkyl; R2 is optionally-substituted C1-C6 alkyl or optionally- substituted cyclopropyl; R3 and R4 are each independently H or optionally- substituted alkyl; R5 is H, optionally-substituted alkyl, acyl, or alkoxycarbonyl; R6 and R7 are each independently H, optionally- substituted alkyl, or R6 and R7 together form a carbocycle; R8 is substituted phenyl or optionally-substituted pyridinyl, provided that if R8 is substituted phenyl, then R2 is optionally-substituted cyclopropyl; and R9, R10 and R11 are each independently H, halo, or optionally- substituted alkyl.

structures with greatly improved selectivity for Kv7.2/Kv7.3 over related potassium channels, i.e., Kv7.3/Kv7.5, Kv7.4, and Kv7.4/7.5. RL-36 and RL-12 maintain an agonist EC2x of ca. 1 μM on Kv7.2/Kv7.3 in a high-throughput assay on an automated electrophysiology platform in HEK293 cells but lack activity on Kv7.3/Kv7.5, Kv7.4, and Kv7.4/7.5, resulting in a selectivity index SI > 10. RL-56 is remarkably
