title: Synthesis of some novel sulfur containing triazolothienopyrimidines and biscompounds as possible antitumor and radioprotective agents.
abstract: The syntheses of novel 1,2,4-triazolothienopyrimidine derivatives (4a,b), thiourea derivatives (5-8) and biscompounds having a thieno[2,3-d]pyrimidine nucleus (13-16) utilizing the 2-isothiocyanato derivatives 2a,b are reported. The structures of these compounds were confirmed by microanalysis, IR, 1H-NMR and mass spectrometry. Preliminary biological studies of some synthesized compounds showed promising antitumor and radioprotective activities.
