This ADC product is comprised of an anti-CEACAM6 monoclonal antibody conjugated via a MC-Vc-PAB linker to SN38. The SN-38 is targeted to certain cancers by immunerecognition and delivered into cancer cells via receptor mediated endocytosis. Within the cell, SN-38 binds to DNA, causes DNA damage.
This gene encodes a protein that belongs to the carcinoembryonic antigen (CEA) family whose members are glycosyl phosphatidyl inositol (GPI) anchored cell surface glycoproteins. Members of this family play a role in cell adhesion and are widely used as tumor markers in serum immunoassay determinations of carcinoma. This gene affects the sensitivity of tumor cells to adenovirus infection. The protein encoded by this gene acts as a receptor for adherent-invasive E. coli adhesion to the surface of ileal epithelial cells in patients with Crohn's disease. This gene is clustered with genes and pseudogenes of the cell adhesion molecules subgroup of the CEA family on chromosome 19.
Peptide linkers, belonging to Enzymatically cleavable linkers, combine greater systemic stability with rapid enzymatic release of the drug in the target cell. The scission of peptidic bonds relies on lysosomal proteolytic enzymes, which have very low activities in blood due to endogenous inhibitors and the unfavorably high pH value of blood.
ADC payload drug
Name
SN-38 (7-ethyl-10-hydroxycamptothecin)
Description
SN38 (7-ethyl-10-hydroxy camptothecin) is an active metabolite of the cancer prodrug, irinotecan, with the ability of inhibiting Topoisomerase I, which is belong to the camptothecin family. SN-38 is formed via hydrolysis of irinotecan by carboxylesterases and metabolized via glucuronidation by UGT1A1.
