P-glycoprotein (P-gp) is an important factor in the development of multidrug resistance (MDR) in cancer cells. In literature reports, a thieno[2,3-d]pyrimidine (QB13) was described as P-gp modulator and opposed effects on the cell accumulation of distinct

The reaction of 2-benzoylthioureidothiophene-3-carbonitriles D/8,9 with diluted NaOH yields 4-amino-thienopyrimidin-2(1H)-thiones E/10,11.Compounds D react in alkaline solution with various alkyl halides in one step to give 2-alkylthio-4-amino-thie
