Gemcitabine elaidate (CP-4126), is a lipophilic, unsaturated fatty acid ester derivative of gemcitabine (dFdC), an antimetabolite deoxynucleoside analogue, with potential antineoplastic activity. Upon hydrolysis intracellularly by esterases, the prodrug gemcitabine is converted into the active metabolites difluorodeoxycytidine di- and tri-phosphate (dFdCDP and dFdCTP) by deoxycytidine kinase. dFdCDP inhibits ribonucleotide reductase, thereby decreasing the deoxynucleotide pool available for DNA synthesis; dFdCTP is incorporated into DNA, resulting in DNA strand termination and apoptosis.

Gemcitabine elaidate (CP-4126) hydrochloride is lipophilic pro-drug of Gemcitabine. Gemcitabine elaidate hydrochloride is converted to Gemcitabine by esterases in order to be phosphorylated. In contrast to gemcitabine, Gemcitabine elaidate hydrochloride could be administered orally, with a schedule and dose dependent toxicity and antitumor activity.
