SBI-581（Cat No.:I043632）is a selective small molecule inhibitor designed to target and inhibit the activity of histone deacetylases (HDACs), enzymes that play a key role in regulating gene expression through chromatin remodeling. By inhibiting HDACs, SBI-581 aims to alter gene expression patterns that control cell growth, differentiation, and survival. This compound is being explored for its potential therapeutic applications in cancer and other diseases where abnormal gene expression contributes to disease progression. SBI-581’s ability to modify epigenetic regulation makes it a promising candidate for treating cancers and certain neurological disorders.
