Herein we report that combined inhibition of transglutaminase 2 (TG2) and histone deacetylases (HDACs) synergistically protects against toxic stimuli mediated by glutamate. Based on these findings, we designed and synthesized a series of novel dual TG2–HDAC binding agents. Compound 3 [(E)‐N‐hydroxy‐5‐(3‐(4‐(3‐oxo‐3‐(pyridin‐3‐yl)prop‐1‐en‐1‐yl)phenyl)thioureido)pentanamide] emerged as the most interesting
近年来,已经有一个明确的共识,即通过同时调节不同的靶标可以更好地治疗神经退行性疾病。本文中我们报道转谷氨酰胺酶2(TG2)和组蛋白脱乙酰基酶(HDACs)的组合抑制协同保护免受谷氨酸介导的毒性刺激。基于这些发现,我们设计并合成了一系列新颖的双重TG2-HDAC结合剂。化合物3 [(E)‐ N‐羟基‐5‐(3‐(4‐(3‐oxo‐3‐(吡啶基‐3‐基)丙-1-烯‐基‐苯基)苯硫脲基)戊酰胺]出现了作为该系列中最有趣的,能够抑制TG2和HDAC的在体外(TG2 IC 50 = 13.3±1.5μ米,HDAC1 IC 50 = 3.38±0.14μ米,HDAC6 IC 50 = 4.10±0.13μ米),并在基于细胞的测定。此外,化合物3不施加在皮层神经元的任何毒性作用可达50μ米,并保护神经元免于由谷氨酸(5米诱导毒性损伤米)与EC 50为3.7±0.5μ值米。
