A novel series of substituted (thieno[2,3-d]pyrimidin-4-ylthio)carboxylic acids has been synthesized and tested in vitro towards human protein kinase CK2. It was revealed that the most active compounds inhibiting CK2 are 3-{[5-(4-methylphenyl)thieno[2,3-d]pyrimidin-4-yl]thio}propanoic acid and 3-{[5-(4-ethoxyphenyl)thieno[2,3-d]pyrimidin-4-yl]thio}propanoic acid (IC(50) values are 0.1 μM and 0.125 μM, respectively). Structure-activity relationships of 28 tested thienopyrimidine derivatives have been studied and binding mode of this chemical class has been predicted. Evaluation of the inhibitors on seven protein kinases revealed considerable selectivity towards CK2.
