  Pyrimidine-2,4,6-trione Derivatives and Their Inhibition of Mutant SOD1-Dependent Protein Aggregation. Toward a Treatment for Amyotrophic Lateral Sclerosis

  摘要：

  Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by the progressive loss of motor neurons, leading to muscle weakness, paralysis, and death, most often from respiratory failure. The only FDA-approved drug for the treatment of ALS, riluzole, only extends the median survival in patients by 2-3 months. There is an urgent need for novel therapeutic strategies for this devastating disease. Using a high-throughput screening assay targeting an ALS cultured cell model (PC12-G93A-YFP cell line), we previously identified three chemotypes that were neuroprotective. We present a further detailed analysis of one promising scaffold from that group, pyrimidine-2,4,6-triones (PYTs), characterizing a number of PYT analogues using SAR and ADME. The PYT compounds show good potency, superior ADME data, low toxicity, brain penetration, and excellent oral bioavailability. Compounds from this series show 100% efficacy in the protection assay with a good correlation in activity between the protection and protein aggregation assays. The modifications of the PYT scaffold presented here suggest that this chemical structure may be a novel drug candidate scaffold for use in clinical trials in ALS.

  The reactions are rapid, efficient, selective, and versatile, and can be performed in benign solvents, giving products in excellent yields with minimal efforts for purification. The characteristics of the reactions meet the requirements of a click reaction. The use of trifluoromethyl trifluoromethanesulfonate as a click reagent is advantageous over other "CO" sources (e.g., TsOCF3 , PhCO2 CF3 , CsOCF3

  已证明三氟甲基三氟甲磺酸盐是二氟光气的极佳储存库，并且在无金属和无添加剂条件下制备尿素衍生物，杂环和氨基甲酰氟时，很有希望实现胺的点击连接。该反应快速，高效，选择性和通用，并且可以在良性溶剂中进行，从而以极少的纯化工作即可获得高收率的产物。反应的特征满足点击反应的要求。与其他“ CO”源（例如TsO ，PhCO2 CF3，CsO ，AgO 和三光气）相比，使用三氟甲基三氟甲磺酸盐作为点击试剂是有利的。易于扩展；甚至在无金属和无添加剂的条件下也具有高反应活性。
