A histone deacetylase inhibitor used (as its lactate salt) in combination with bortezomib and dexamethasone for the treatment of multiple myeloma. It has a role as an EC 3.5.1.98 (histone deacetylase) inhibitor, an antineoplastic agent and an angiogenesis modulating agent. It is a hydroxamic acid, a member of cinnamamides, a secondary amino compound and a methylindole. It is a conjugate base of a panobinostat(1+)."}]
