Abstract

This paper describes the design and synthesis of potential inhibitors of Trypanosoma cruzi dihydrofolate reductase using a structure-based approach. A model of the structure of the T. cruzi enzyme was compared with the structure of the human enzyme. The differences were used to design modifications of methotrexate to produce compounds which should be selective for the parasite enzyme. The derivatives of methotrexate were synthesised and tested against the enzyme and intact parasites.
