Abstract: An extension of our previous research work has resulted in a number of new ATP-competitive CK2 inhibitors that have been identified among 4-aminothieno[2,3-d]pyrimidine derivatives. The most active compounds obtained in the course of the research are 3-(5-p-tolyl-thieno[2,3-d]pyrimidin-4-ylamino)-benzoic acid, 5e (NHTP23, IC50 = 0.01 μM), 3-(5-phenyl-thieno[2,3-d]pyrimidin-4-ylamino)-benzoic acid, 5g (NHTP25, IC50 = 0.065 μM) and 3-(6-methyl-5-phenyl-thieno[2,3-d]pyrimidin-4-ylamino)-benzoic acid, 5n (NHTP33, IC50 = 0.008 μM). Structure-activity relationships of the tested 4-aminothieno[2,3-d]pyrimidine derivatives have been studied and their binding mode with ATP-acceptor site of CK2 has been proposed. A negative effect of intramolecular hydrogen bonding in the compounds' structure is discussed.
