Description: Tenifatecan, also known as SN2310, is an injectable emulsion composed of 7-ethyl-10-hydroxycamptothecin (SN-38) conjugate with vitamin E through a succinate linker. SN-38 is the active metabolite of irinotecan. SN-38 binds to and inhibits topoisomerase I by stabilizing the cleavable complex between topoisomerase I and DNA, resulting in DNA breaks, inhibition of DNA replication, and apoptosis. SN-38 has been reported to exhibit up to 1,000-fold more cytotoxic activity against various cancer cells in vitro than irinotecan.

Price and Availability




Tenifatecan is not in stock, may be available through custom synthesis. For cost-effective reason, minimum 1 gram order is requested. The product will be characterized by NMR, HPLC and MS analysis. Purity (HPLC) is usually >98%. CoA, QC data, MSDS will be provided when product is successfully made. The estimated lead time is 2-3 months. Please send email to sales@medkoo.com to inquire quote.

Additional Information

SN2310 is a novel camptothecin for the treatment of cancer. Camptothecins are potent anticancer agents that belong to the family of drugs called topoisomerase I inhibitors that bind reversibly to the TOPO-I-DNA complex causing breaks in the DNA strands during replication resulting in cell death.  SN2310 Injectable Emulsion is an oil-and-water emulsion that incorporates a new derivative of SN-38, SN2310. The conjugation of SN-38 to Vitamin E succinate enables increased solubility in a vitamin E-based, oil-in-water emulsion that can be administered without dilution. The difference in the structure is shown in the right sidebar. SN2310 Injectable Emulsion is being developed with the objective of demonstrating improved anti-tumor activity as a result of increased exposure to SN-38 based on a longer half-life. In addition, the product is more convenient, with a shorter duration of administration and no requirement for reconstitution. (from: http://www.oncogenex.ca/products/SN2310.html).
