Description:

WARNING: This product is for research use only, not for human or veterinary use.

Raltitrexed, also known as ZD 1694, is an antimetabolite drug used in treatment of colorectal cancer since 1998. It may also be used in the treatment of malignant mesothelioma. It is an inhibitor of thymidylate synthase, and is manufactured by AstraZeneca. Raltitrexed is a quinazoline folate analogue with antineoplastic activity. After transport into cells via the reduced folate carrier, raltitrexed undergoes intracellular polyglutamation and blocks the folate-binding site of thymidylate synthase, thereby inhibiting tetrahydrofolate activity and DNA replication and repair and resulting in cytotoxicity.

More Info
Raltitrexed is chemically similar to folic acid and is in the class of chemotherapy drugs called folate antimetabolites, which inhibit one or more of three enzymes that use folate and deriavtives as substrates: DHFR, GARFT and Thymidine synthase. Raltitrexed is fully active after polyglutamylation, which allows cellular retention of the drug.  By inhibiting Thymidine synthase (TS), thus formation of precursor pyrimidine nucleotides, raltitrexed prevents the formation of DNA and RNA, which are required for the growth and survival of both normal cells and cancer cells. Inhibition of L1210 cell growth in culture IC50 = 9 nM, is one of the strongest antimetabolites in use. [source: http://en.wikipedia.org/wiki/Raltitrexed).      
Product Data
Biological target:
Raltitrexed is a thymidylate synthase inhibitor with an IC50 of 9 nM for the inhibition of L1210 cell growth. After transport into cells via the reduced folate carrier, raltitrexed undergoes intracellular polyglutamation and blocks the folate-binding site of thymidylate synthase, thereby inhibiting tetrahydrofolate activity and DNA replication and repair, resulting in cytotoxicity.
In vitro activity:
Raltitrexed enhanced the antitumor effects of anlotinib on human esophageal squamous cell carcinoma cells by down-regulating phosphorylation of Akt and Erk. Reference: BMC Cancer. 2023 Mar 4;23(1):207. https://pubmed.ncbi.nlm.nih.gov/36870981/
In vivo activity:
Raltitrexed was able to prevent mortality and reduce the number of tachyzoites in the peritoneal fluid and liver imprints of mice infected with Toxoplasma gondii. Raltitrexed has important protective activities against the T. gondii RH strain. Reference: Parasitol Res. 2018 May;117(5):1465-1471. https://pubmed.ncbi.nlm.nih.gov/29550996/
