Anti-FCER2 (Gomiliximab)-SMCC-DM1 ADC (ADC-W-1142)

This ADC product is comprised of an anti-FCER2 monoclonal antibody conjugated via a SMCC 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.

 ADC Target

  • Name
  • FCER2
  • Alternative Names
  • FCER2; Fc fragment of IgE, low affinity II, receptor for (CD23); CD23A, Fc fragment of IgE, low affinity II, receptor for (CD23A) , FCE2; low affinity immunoglobulin epsilon Fc receptor; CD23; CLEC4J; BLAST-2; CD23 antigen; fc-epsilon-RII; lymphocyte IgE receptor; immunoglobulin E-binding factor; C-type lectin domain family 4, member J; FCE2; CD23A; IGEBF;
  • Target Entrez Gene ID
  • 2208
  • Overview
  • The protein encoded by this gene is a B-cell specific antigen, and a low-affinity receptor for IgE. It has essential roles in B cell growth and differentiation, and the regulation of IgE production. This protein also exists as a soluble secreted form, then functioning as a potent mitogenic growth factor. Alternatively spliced transcript variants encoding different isoforms have been described for this gene.

 ADC Linker

  • Name
  • SMCC (N-succinimidyl 4-(Nmaleimidomethyl)cyclohexane-1-carboxylate)
  • 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
  • DM1 (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.
