Antifolate thymidylate synthase inhibitor. Antineoplastic. | [Biological Activity]
thymidylate synthase (ts) is a crucial enzyme in the synthesis of 2'-deoxythymidine-5'-monophosphate, an essential precursor for dna biosynthesis. thus, this enzyme is a critical target in cancer chemotherapy. nolatrexed (ag-337) is a non-classical thymidylate synthase inhibitor. | [in vitro]
nolatrexed was designed using x-ray crystallographic data from the ts molecular modeling and folate binding site. it is a non-classical ts inhibitor in that it lacks a terminal glutamate side chain and is uncharged at physiological ph. nolatrexed does not require a specific transport mechanism to enter into cells and, once within the cell, is not a substrate for the enzyme folyl polyglutamate synthetase [1]. | [in vivo]
when nolatrexed was administered to nude mice bearing bu25tk- tumor xenografts, a time-dependent increase in antitumor activity was observed [1]. | [IC 50]
