Description

Description générale

A cell-permeable chlorophenylethynylsulfonamide compound that binds directly to the substrate-binding domain of heat shock protein 70 (HSP70) and disrupts its interaction with client proteins. Impairs the activity of the anaphase promoting complex/cyclosome (APC/C) in cell-free extracts. Arrests cell cycle at G2/M phase and preferentially induces genomic instability in cancer cells (IC₅₀ = 2 to 5 µM in melanoma cell lines). Exhibits much reduced toxicity in non-transformed cells (IC₅₀ >100 µM in primary melanocytes). Induces apoptosis and inhibits autophagy as evidenced by increased p62SQSTM1 and LC3 accumulation. Also, shown to extend life in murine models of pre-B cell lymphoma.
