Abstract: Trypanosoma cruzi trans sialidase (TcTS) has been identified as a potential therapeutic target for treatment of Chagas disease. Thus, rational inhibitor design and screening approaches have been carried out to identify improved trans-sialidase inhibitors. A library of C9-modified difluorosialic acid analogues has been synthesized to evaluate efficacy of these mechanism based inhibitors towards TcTS activity. In search of new inhibitor motifs, screening of nearly 1000 marine sponge extracts was employed, leading to the identification of low µM inhibitors of the  target enzyme.
