This ADC product is comprised of an anti-NCAM1 monoclonal antibody (clone huN901) conjugated via a SPDB linker to [3H]DM1. The [3H]DM1 is targeted to certain cancers by immunerecognition and delivered into cancer cells via receptor mediated endocytosis. Within the cell, [3H]DM1 binds to tubulins, interrupts microtubule dynamics, and subsequently, induces cell death.
ADC Target
- Alternative Names
- NCAM1; neural cell adhesion molecule 1; CD56; NCAM; MSK39; neural cell adhesion molecule, NCAM; antigen recognized by monoclonal antibody 5.1H11;
- Target Entrez Gene ID
- 4684
- Overview
- This gene encodes a cell adhesion protein which is a member of the immunoglobulin superfamily. The encoded protein is involved in cell-to-cell interactions as well as cell-matrix interactions during development and differentiation. The encoded protein has been shown to be involved in development of the nervous system, and for cells involved in the expansion of T cells and dendritic cells which play an important role in immune surveillance. Alternative splicing results in multiple transcript variants.
ADC Antibody
- Overview
- Humanized Anti-NCAM1 Antibody, clone # huN901
ADC Linker
- Name
- SPDB (N-succinimidyl-4-(2-pyridyldithio)butyrate)
- Description
- 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.
ADC payload drug
- Name
- [3H]DM1([3H]N2'-deacetyl-N2'-(3-mercapto-1-oxopropyl)-maytansine)
- Description
- 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.
