Notes: Panobinostat-d4 (hydrochloride) is intended for use as an internal standard for the quantification of panobinostat (Item No. 13280) by GC- or LC-MS. Panobinostat is a pan-inhibitor of histone deacetylases (HDACs; Kis = 0.6-31 nM for HDAC1-11).{19767} It inhibits growth in a panel of 37 human or mouse lung cancer cell lines, including small cell lung cancer (SCLC), non-small cell lung cancer (NSCLC), and mesothelioma cancer cells (IC50s = 4-175, 5-310, and 5-470 nM, respectively), but not NCI H661 mouse NSCLC cells (IC50 = >800 nM).{59793} Panobinostat (20 mg/kg, i.p.) induces tumor regression in BK-T and RG-1 SCLC mouse xenograft models.
