95058-81-4 - Application:

Gemcitabine (CAS: 95058-81-4) is a chemotherapy medication used to treat a number of types of cancer. This includes breast cancer, non-small cell lung cancer, pancreatic cancer, bladder cancer, and biliary tract cancer. Gemcitabine is being investigated for use in esophageal cancer, and is used experimentally in lymphomas and various other tumor types. Gemcitabine is administered by the intravenous route, since it is extensively metabolized by the gastrointestinal tract.
Gemcitabine is a nucleotide analogue, which belongs to the anti-metabolic class of anticancer drugs. It mainly acts on DNA synthesis phase, that is, S phase. Under certain conditions, it can prevent G1 phase from progressing to S phase. It has the characteristics of wide anticancer spectrum, unique mechanism of action, low toxicity, no cross-resistance to other chemotherapy drugs and no superposition of toxicity. Chemicalbook, gemcitabine, is now approved for use in more than 90 countries, making it the first-line treatment for non-small cell lung cancer and the "gold standard" for pancreatic cancer.
In 1999, CFDA approved gemcitabine for the treatment of locally advanced or metastatic NSCLC, locally advanced or metastatic pancreatic cancer; In 2010, CChemicalbookFDA approved gemcitabine in combination with paclitaxel for the treatment of unresectable, locally recurrent or metastatic breast cancer that has recurred after adjuvant/neoadjuvant chemotherapy.
Gemcitabine is a broad-spectrum antimetabolite and deoxycytidine analogue with antineoplastic activity. Upon administration, gemcitabine is converted into the active metabolites difluorodeoxycytidine diphosphate (dFdCDP) and difluorodeoxycytidine triphosphate (dFdCTP) by deoxycytidine kinase. dFdCTP competes with deoxycytidine triphosphate (dCTP) and is incorporated into DNA. This locks DNA polymerase thereby resulting in masked termination during DNA replication. On the other hand, dFdCDP inhibits ribonucleotide reductase, thereby decreasing the deoxynucleotide pool available for DNA synthesis. The reduction in the intracellular concentration of dCTP potentiates the incorporation of dFdCTP into DNA.
