We have identified chemical probes that act as dual phosphodiesterase 5 (PDE5) and histone deacetylase 6 (HDAC6)-selective inhibitors (>1 log unit difference versus class I HDACs) to decipher the contribution of HDAC isoforms to the positive impact of dual-acting PDE5 and HDAC inhibitors on mouse models of Alzheimer's disease (AD) and fine-tune this systems therapeutics approach. Structure- and knowledge-based
我们已经鉴定出可以用作双磷酸二酯酶5(PDE5)和组蛋白脱乙酰基酶6(HDAC6)选择性抑制剂的化学探针(与I类HDAC的对数差异大于1 log单位),以破译HDAC同工型对双作用的积极影响PDE5和HDAC抑制剂可用于阿尔茨海默氏病(AD)小鼠模型,并微调该系统治疗方法。基于结构和知识的方法导致设计出具有所需目标化合物特征的同类分子:双重PDE5和HDAC6选择性抑制剂。满足生化,功能和ADME-Tox分析要求并表现出足够药代动力学特性的化合物44b被选作药理学工具化合物,并在AD小鼠模型(Tg2576)中进行了体内测试。
