Description: Pyroxamide is a synthetic derivative of hydroxamic acid with antineoplastic properties, Pyroxamide inhibits histone deacetylases involved in transcription; induces hyperacetylation of core histones, modulating chromatin structure and affecting transcription of some genes that inhibit tumor growth; and induces growth arrest and apoptosis. Pyroxamide is used in clinical studies for cancer chemotherapy.
