Anti-E. coli Stx2B (Urtoxazumab)-MC-Vc-PAB-SN38 ADC (CAT#: ADC-W-2142)

This ADC product is comprised of an anti-E. coli Stx2B 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.

  • Overview
  • Shiga toxins are a family of related toxins with two major groups, Stx1 and Stx2, expressed by genes considered to be part of the genome of lambdoid prophages. The toxin has two subunits—designated A(mol. wt. 32000 D) and B(mol. wt. 7700 D)—and is one of the AB5 toxins. The B subunit is a pentamer that binds to specific glycolipids on the host cell, specifically globotriaosylceramide (Gb3). Following this, the A subunit is internalised and cleaved into two parts. The A1 component then binds to the ribosome, disrupting protein synthesis.

  • 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.
