Pharmacokinetic comparison of leucovorin and levoleucovorin

European Journal of Clinical Pharmacology, 1993
The pharmacokinetic values of d,l-leucovorin and l-leucovorin were compared in eight healthy volunteers following oral administration of 25 mg d,l-leucovorin and 12.5 mg l-leucovorin. Serum levels of l-5-formyltetrahydrofolate, l-5-methyltetrahydrofolate, and total reduced folates were measured by an established microbiological method.

Leucovorin as a Prodrug

1993
To exert its antitumor effects, leucovorin must ultimately become activated by conversion to CH2FH4.* Elevation of this reduced folate cofactor stabilizes the inhibitory ternary complex formed between the FU active metabolite, FdUMP and thymidylate synthase, resulting in suppression of DNA synthesis or repair.1–4 It has been demonstrated both in animal

The metabolic role of leucovorin

Trends in Biochemical Sciences, 1993
Interest in determining if leucovorin, known chemically as 5-formyltetra-hydrofolate, plays a role in one-carbon metabolism is reemerging. While investigations in the 1940s suggested it was an important donor of one-carbon units in folate-mediated biosynthetic reactions, studies between the 1950s and 1980s disproved this hypothesis and dismissed its ...
