Alzheimer's disease. A set of 39 compounds was synthesized and evaluated in kinase activity assays for their ability to inhibit both target kinases. Among the synthesized compounds, potent dual-target-directed inhibitors showing IC50 values down to the low double-digit nanomolar range, were identified. One of the best balanced dual inhibitors presented in here is N-(4-(2-ethyl-4-(4-fluorophenyl)-1H-imidazol
同时抑制参与同一复杂疾病进展的两个靶标的化合物可能会表现出累加甚至协同的治疗作用。在这里,我们介绍了2,4,5-三取代的咪唑类化合物,作为p38α丝裂原活化蛋白激酶和糖原合酶激酶3β(GSK3β)的双重抑制剂。两种酶都是神经退行性疾病(例如阿尔茨海默氏病)的潜在治疗靶标。合成了39种化合物,并在激酶活性测定中评估了它们抑制两种靶激酶的能力。在合成的化合物中,鉴定出了显示出低至两位数纳摩尔范围低的IC 50值的有效的双靶标抑制剂。这里介绍的最佳平衡双重抑制剂之一是N-(4-(2-乙基-4-(4-氟苯基)-1 H-咪唑-5-基)吡啶-2-基)环丙烷甲酰胺(20c)(p38α,IC 50 = 16 nM;GSK3β,IC 50 = 35 nM)具有优异的代谢稳定性和比密切相关的GSK3α明显的同工型选择性。我们的发现通过基于先前发布的X射线结构的计算机对接研究得到了合理化。
