一般描述
A bioavailable, moderately toxic, deoxyctytidine analog with anti-metabolite and anti-tumor properties. Shown to be effective against a variety of tumors and blocks the growth of cancer cells in culture (IC 50 = 8.7, 57, 3.7, and 36 nM for L1210, CEM, Caco2, and HeLa cells, respectively). Following its uptake into cells by nucleoside transporters it is phosphorylated to its mono (dFdCMP), di (dFdCDP), and triphosphorylated (dFdCTP) forms by deoxycytidine kinase. dFdCDP and dFdCTP are reported to inhibit the activity of ribonucleotide reductase and impede DNA synthesis and repair mechanisms and induce cell death. Blocks the progression of cells through the G1/S phase. The dFdCTP is shown to compete with endogenous deoxycytidine triphosphate (dCTP) for incorporation into DNA and against CTP into RNA. Gemcitabine is also shown to block mitochondrial DNA polymerase γ. Works synergistically with other chemotherapeutic agents to enhance their cytotoxicity. Its half life is reported to be 42 to 94 min (depending upon the age and sex of the individual).

Most patients with advanced pancreas cancer experience pain and must limit their daily activities because of tumor-related symptoms. To date, no treatment has had a significant impact on the disease. In early studies with gemcitabine, patients with pancreas cancer experienced

Gemcitabine (2',2'-difluorodeoxycytidine) is a novel pyrimidine nucleoside drug with clinical efficacy in several common epithelial cancers. We have proposed that gemcitabine requires nucleoside transporter (NT) proteins to permeate the plasma membrane and to exhibit pharmacological activity. In humans, there are

Clinical refractoriness to nucleoside analogs (e.g., gemcitabine, capecitabine) is a major scientific problem and is one of the main reasons underlying the extremely poor prognostic state of pancreatic cancer. The drugs' effects are suboptimal partly due to cellular mechanisms limiting

We showed that the efficacy of the new 2'-deoxycytidine (2'-dCyd) analogue antimetabolite 2'-deoxy-2'-methylidenecytidine (DMDC) correlates well with tumor levels of cytidine (Cyd) deaminase in human cancer xenograft models. DMDC was highly effective in tumors with higher levels of Cyd deaminase

Gemcitabine, 2'-deoxy-2', 2'-difluorocytidine (dFdC), is a drug approved for use against various solid tumors. Clinically, this moderately toxic nucleoside analog causes peripheral neuropathy, hematological dysfunction, and pulmonary toxicity in cancer patients. Although these side effects closely mimic symptoms of mitochondrial
