抑制沉默调节蛋白2脱乙酰酶介导帕金森病和亨廷顿病(HD)的细胞和无脊椎动物模型中的保护作用。在这里,我们报告了在两个遗传性HD小鼠模型的脑渗透性sirtuin 2抑制剂的体内疗效。化合物治疗导致运动功能改善、生存期延长和脑萎缩减少,并与聚集的突变亨廷顿蛋白(HD病理学的标志)显著减少相关。我们的研究结果提供了SIRT2抑制作为HD潜在治疗靶点的临床前验证,并支持进一步开发SIRT2抑制剂用于人体测试。
Inhibition of sirtuin 2 deacetylase mediates protective effects in cell and invertebrate models of Parkinson’s disease and Huntington’s disease (HD). Here we report the in vivo efficacy of a brain-permeable sirtuin 2 inhibitor in two genetic mouse models of HD. Compound treatment resulted in improved motor function, extended survival, and reduced brain atrophy and is associated with marked reduction of aggregated mutant huntingtin, a hallmark of HD pathology. Our results provide preclinical validation of SIRT2 inhibition as a potential therapeutic target for HD and support the further development of SIRT2 inhibitors for testing in humans.
