MedKoo CAT#: 406571

CAS#: 5690-03-9

Description: Splitomicin is a cell-permeable lactone derived from naphthol and known to be a potent selective inhibitor of Sir2 (silent information regulator 2) and HDAC. Splitomicin inhibits the NAD+-dependent deacetylase activity of Sir2 in vitro. It increases the levels of cyclic AMP by inhibiting the activity of cyclic AMP phosphodiesterase, interferes with mobilization of intracellular Ca+2 and ATP release.
