Summary: https://www.creative-biolabs.com/adc/target-ms4a1-68.htm This ADC product is comprised of an anti-MS4A1 monoclonal antibody (Veltuzumab) conjugated via a SPP linker to DM1. The DM1 is targeted to certain cancers by immunerecognition and delivered into cancer cells via receptor mediated endocytosis. Within the cell, DM1 binds to tubulins, interrupts microtubule dynamics, and subsequently, induces cell death. Disulfide Linkers, are extensively exploited as a chemically labile linkage. Since the release of disulfide-linked drugs requires a cytoplasmic thiol cofactor, such as glutathione (GSH). Disulfides maintain stable at physiological pH and only when ADCs are internalized inside cells, the cytosol provides reducing environment including intracellular enzyme protein disulfide isomerase, or similar enzymes, drugs can be released. "Derived from Maytansinoid,a group of cytotoxins structurally similar to rifamycin, geldanamycin, and ansatrienin. The eponymous natural cytotoxic
Description: https://www.creative-biolabs.com/adc/target-ms4a1-68.htm This ADC product is comprised of an anti-MS4A1 monoclonal antibody (clone 2H7) conjugated via a MCC linker to a DM1. The DM1 is targeted to certain cancers by immunerecognition and delivered into cancer cells via receptor mediated endocytosis. Within the cell, DM1 binds to tubulins, interrupts microtubule dynamics, and subsequently, induces cell death. Noncleavable linkers, is considered noncleavable-meaning linker cleavage, and payload release does not depend on the differential properties between the plasma and some cytoplasmic compartments. Instead, the release of the cytotoxic drug is postulated to occur after internalization of the ADC via antigen-mediated endocytosis and delivery to lysosomal compartment, where the antibody is degraded to the level of amino acids through intracellular proteolytic degradation. "Derived from Maytansinoid,a group of cytotoxins structurally similar to rifamycin, geldanamycin, and ansatrienin. The eponymous natural cytotoxic agent maytansine is a 19-member lactam (ansa macrolide) structure originally isolated from the Ethiopian shrub Maytenus ovatus. Maytansinoids can bind to tubulin at or near the vinblastine-binding site, which interfere the formation of microtubules and depolymerize already formed microtubules, inducing mitotic arrest in the intoxicated cells."
