NCIt definition : An orally available 5-fluorouracil (5-FU) prodrug with potential antineoplastic activity.
Upon administration, galocitabine is converted into 5'-deoxy-5-fluorocytidine, 5'-deoxy-fluorouridine,
and 5-FU. 5-FU is further metabolized into other cytotoxic metabolites that interfere
with RNA and DNA synthesis via inhibition of thymidylate synthase. As a result, this
agent eventually inhibits tumor cell growth.;
