摘要
Bisubstrate-type compound Lys-CoA has been shown to inhibit the p300 histone acetyl transferase activity efficiently and may constitute a lead compound for a novel class of anticancer therapeutics. Based on this strategy, we synthesized a series of CoA derivatives and evaluated these molecules for their activity as p300 histone acetyltransferases inhibitor. The best activity was obtained with compound 3 bearing a C-5 spacing linker that connects the CoA moiety to a tert-butyloxycarbonyl (Boc) group. Based on docking simulations, this inhibitor exhibits favorable interactions with two binding areas, namely pockets P1 and P2, within the active site.
