Anti-C. diff toxin B (Bezlotoxumab)-MC-Vc-PAB-SN38 ADC (CAT#: ADC-W-2064)

This ADC product is comprised of an anti-C. diff toxin B monoclonal antibody conjugated via a MC-Vc-PAB linker to SN38. The SN-38 is targeted to certain cancers by immunerecognition and delivered into cancer cells via receptor mediated endocytosis. Within the cell, SN-38 binds to DNA, causes DNA damage.

  • Name
  • C. diff toxin B
  • Alternative Names
  • C. diff toxin B, Clostridium difficile Toxin B
  • Overview
  • Clostridium difficile Toxin B (tcdB or ToxB) is a glucosyltranferase which is known to innactivate Rho, Cdc42 and Rac within target cells. This toxin is encoded on a pathogenicity region of the C. difficile chromossome and is expressed during the log and stationary phases of growth in response to a variety of environmental stimuli.
  • Overview
  • Human Anti-C. diff toxin B IgG1-kappa antibody, Bezlotoxumab
  • Generic name
  • Bezlotoxumab
  • Host animal
  • Human
  • Name
  • MC-Vc-PAB (maleimidocaproyl-valine-citrulline-p-aminobenzoyloxycarbonyl)
  • Description
  • Peptide linkers, belonging to Enzymatically cleavable linkers, combine greater systemic stability with rapid enzymatic release of the drug in the target cell. The scission of peptidic bonds relies on lysosomal proteolytic enzymes, which have very low activities in blood due to endogenous inhibitors and the unfavorably high pH value of blood.
  • Name
  • SN-38 (7-ethyl-10-hydroxycamptothecin)
  • Description
  • SN38 (7-ethyl-10-hydroxy camptothecin) is an active metabolite of the cancer prodrug, irinotecan, with the ability of inhibiting Topoisomerase I, which is belong to the camptothecin family. SN-38 is formed via hydrolysis of irinotecan by carboxylesterases and metabolized via glucuronidation by UGT1A1.
