Anti-IL23A (Tildrakizumab)-SPDB-DM4 ADC (CAT#: ADC-W-1353)

This ADC product is comprised of an anti-IL23A monoclonal antibody 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.

  • Target Entrez Gene ID
  • 51561
  • Overview
  • This gene encodes a subunit of the heterodimeric cytokine interleukin 23 (IL23). IL23 is composed of this protein and the p40 subunit of interleukin 12 (IL12B). The receptor of IL23 is formed by the beta 1 subunit of IL12 (IL12RB1) and an IL23 specific subunit, IL23R. Both IL23 and IL12 can activate the transcription activator STAT4, and stimulate the production of interferon-gamma (IFNG). In contrast to IL12, which acts mainly on naive CD4(+) T cells, IL23 preferentially acts on memory CD4(+) T cells.
  • Overview
  • Humanized Anti-IL23A IgG1-kappa antibody, Tildrakizumab
  • Generic name
  • Tildrakizumab
  • Host animal
  • Mouse
  • 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.
  • 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.
