The successful treatment of Helicobacter pylori infections is becoming increasingly difficult due to the rise of resistance against current broad spectrum triple therapy regimens. In the search for narrow-spectrum agents against H. pylori, a high-throughp

The clinical evidence for the success of tyrosine kinase inhibitors in combination with microtubule-targeting agents prompted us to design and develop single agents that possess both epidermal growth factor receptor (EGFR) kinase and tubulin polymerization inhibitory properties. A series of 6-aryl/heteroaryl-4-(3′,4′,5′-trimethoxyanilino)thieno[3,2-d]pyrimidine derivatives were discovered as novel dual tubulin polymerization and EGFR kinase inhibitors. The 4-(3′,4′,5′-trimethoxyanilino)-6-(p-tolyl)thieno[3,2-d]pyrimidine derivative 6g was the most potent compound of the series as an antiproliferative agent, with half-maximal inhibitory concentration (IC50) values in the single- or double-digit nanomolar range. Compound 6g bound to tubulin in the colchicine site and inhibited tubulin assembly with an IC50 value of 0.71 μM, and 6g inhibited EGFR activity with an IC50 value of 30 nM. Our data suggested that the excellent in vitro and in vivo profile of 6g may be derived from its dual inhibition of tubulin polymerization and EGFR kinase.

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.
