General description

A cell-permeable and water soluble hydrazinobenzoylcurcumin (HBC) compound that acts as a selective, reversible and mixed mode inhibitor of p300/CBP and PCAF histone acetyltransferases (IC₅₀ ≤ 25 and 50 µM, respectively) with minimal activity towards other histone modifying enzymes like, G9a, CARM1, HDAC1, SIRT2 and TIP60 (IC₅₀ >100 µM). Blocks the autoacetylation of p300 and PCAF and histone acetylation, downregulates cyclin E expression and induces senescence-like growth arrest at 100 µM in KB cells. Further, suppresses tumor growth in xenograft oral tumor nude mouse model (100 mg/kg, i.p., b.i.d.) and reduces H3K14 and H3K9 acetylation levels. Reported to potently inhibit bFGF-induced bovine aortic endothelial cells (BAECs) invasion and tube formation with an IC₅₀ of 0.93 µM and binds to Ca²⁺/calmodulin with high-affinity (K_d = 8.11 µM) and antagonize its functions in HCT15 cells.
