Selective inhibitors of death in mutant huntingtin cells

Huntington disease (HD) is an inherited neurodegenerative disorder with unclear pathophysiology. We developed a high-throughput assay in a neuronal cell culture model of HD, screened 43,685 compounds and identified 29 novel selective inhibitors of cell death in mutant huntingtin-expressing cells. Four compounds were active in diverse HD models, which suggests a role for cell death in HD; these compounds are mechanistic probes and potential drug leads for HD.
