This ADC product is comprised of an anti-Fibrin II-beta chain Fab' fragment conjugated via a SPDB linker to DM4. The DM4 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.
ADC Target
- Name
- Fibrin II-beta chain
- Alternative Names
- Fibrin II-beta chain
- Overview
- Fibrin (also called Factor Ia) is a fibrous, non-globular protein involved in the clotting of blood. It is formed from fibrinogen by the protease thrombin, and is then polymerised to form a "mesh" that forms a hemostatic plug or clot (in conjunction with platelets) over a wound site.Fibrin is involved in signal transduction, blood coagulation, and platelet activation.

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
- DM4 (N2'-Deacetyl-N2'-(4-mercapto-4-methyl-1-oxopentyl)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.
