  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.

  A sensitive amine-responsive disassembly of self-assembled AuI -CuI double salts was observed and its utilization for the synergistic catalysis was enlightened. Investigation of the disassembly of [Au(NHC)2 ][CuI2 ] revealed the contribution of Cu-assisted ligand exchange of N-heterocyclic carbene (NHC) by amine in [Au(NHC)2 ]+ and the capacity of [CuI2 ]- on the oxidative step.
