L002 is a novel potent, specific acetyltransferase p300 (KAT3B) inhibitor with an IC50 of 1.98 uM. L002 has weak inhibitory effects against PCAF and GCN5 (IC50s =35 and 34 µM, respectively) and is specific for p300 over a panel of additional acetyltransferases, deacetylases, and methyltransferases[1]. L002 blocks histone acetylation and p53 acetylation, and inhibits STAT3 activation[2].
