The core histone tail domains are critical regulators of chromatin structure and function and modifications such as acetylation of lysine residues within the tails are central to this regulation. Studies have shown that the removal of core histone tail domains by trypsinization in which one-half to two-thirds of each core histone tail domain are removed in gross aspects mimics the acetylation of core...
Quinazolinone derivatives I and their methyl esters were synthesized and evaluated as nonclassical lipophilic inhibitors of thymidylate synthase. Compounds Ib and Ic containing OH and CO 2 H as R substituents, respectively, were most effective, indicating that hydrogen bonding may contribute to the increased inhibitory activity. These compounds further showed high cytotoxic activity against...
