Abstract

Antifolate drugs are molecules directed to interfere with the folate metabolic pathway at some level. They can be recognized among the first rationally designed compounds applying the principle of structural analogy with the substrate developing the antimetabolite strategy. This strategy has taken advantage of the basic different features of the microbial and human folate metabolism and therefore allows targeting the pathway at different steps generating a specificity tools for Medicinal Chemists. Two main problems are giving renewed importance to such targets and therefore improving the efforts to discover new targets in the folate metabolism area. The first one is the increasing resistance to the present drugs due to different mechanisms such as the enzyme modification and the increased production of enzymes with not well recognized importance. The second one is the development of techniques directed to highlight the interference at genetic level of molecular probes as antifolate drug to develop new enzymes previously unknown. This approach is defined as genetic approach to drug discovery, from gene to drugs. The present article describes the importance in drug design and discovery of some antifolate targets among the best known at the present status of research such as thymidylate synthase (TS), dhydrofolate reductases, (DHFR) serine hydroxymethyltransferase (SHMT), folyilpolyglutamyl synthetase (FPGS), gamma-glutamyl hydrolase (gamma-GH), glycinamide-ribonucleotide transformylase (GARTfase), amino-imidazole-carboxamide-ribonucleotide transformylase (AICARTfase) and Folate transporters. Discovery, known functions, structure/function studies and inhibition will be described
