Polyglutamine Aggregation Inhibitor III, C2-8 is a cell-permeable amidosulfonamide compound that potently and effectively inhibits polyglutamine (polyQ) aggregation in Huntington′s disease (HD) CA1 neuronal hippocampal sections at a range of 0.1 muM - 10 muM, and in PC12 Htt-103Q-EGFP cells with an IC50 of 50 nM. In addition, Polyglutamine Aggregation Inhibitor III, C2-8 alleviates progressive neurodegeneration in Drosophila expressing Httex1 93QP in a dose-dependent manner. Polyglutamine Aggregation Inhibitor III, C2-8 is a synthetic compound classified as a sulfonamide.
