| Hazard Information | Back Directory | [Description]
LY249543, the S-isomer of lometrexol, is a Methylenetetrahydrofolate Dehydrogenase/Cycl inhibitor. Lometrexol is a folate analog antimetabolite with antineoplastic activity. | [Uses]
LY243246 ((6S)-DDATHF), the 6S diastereomer of DDATHF, is a potent competitive inhibitor of 5’-phosphoribosylglycinamide formyltransferase (GAR transformylase). 6R- and 6S-diastereomers of DDATHF are remarkably similar and equiactive antimetabolites inhibitory to de novo purine synthesis[1]. | [References]
