nervous system (CNS)-penetrant ROCK inhibitor. Identifying a compound that could be dosed orally in mice with selectivity against other AGC kinases, including protein kinase G (PKG), whose inhibition could potentially activate the ROCK pathway, was paramount for the program. We describe the optimization of published ligands to identify a novel series of ROCK inhibitors based on a piperazine core. Morphing
Rho 激酶 (ROCK) 通路涉及多种疾病的发病机制,包括神经系统疾病。在亨廷顿病 (HD) 中,ROCK 与突变亨廷顿 (HTT) 聚集和神经毒性有关,并且 ROCK 通路的成员在 HD 小鼠模型和患者中增加。为了验证这种作用模式作为 HD 的潜在治疗方法,我们寻求一种有效的、选择性的、中枢神经系统 (CNS) 渗透性 ROCK 抑制剂。确定一种可以在小鼠中口服给药的化合物,该化合物对其他 AGC 激酶具有选择性,包括蛋白激酶 G (PKG),其抑制作用可能会激活 ROCK 通路,对于该计划至关重要。我们描述了已发表的配体的优化,以识别基于哌嗪核心的一系列新型 ROCK 抑制剂。
