Chemische Eigenschaften
Tan Solid
Verwenden
Antifolate thymidylate synthase inhibitor. Antineoplastic.
Biologische Aktivität
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
1.0, 0.81 and 1.0 μm for l1210, ccrf-cem and gc3/m tk- cell lines, respectively
