Anti-PDCD1 (Pidilizumab)-MC-Vc-PAB-SN38 ADC (ADC-W-1704)

This ADC product is comprised of an anti-PDCD1 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.

 ADC Target

  • Name
  • PDCD1
  • Alternative Names
  • PDCD1; programmed cell death 1; programmed cell death protein 1; CD279; PD1; protein PD-1; PD-1; SLEB2; hPD-1; hPD-l;
  • Target Entrez Gene ID
  • 5133
  • Overview
  • This gene encodes a cell surface membrane protein of the immunoglobulin superfamily. This protein is expressed in pro-B-cells and is thought to play a role in their differentiation. In mice, expression of this gene is induced in the thymus when anti-CD3 antibodies are injected and large numbers of thymocytes undergo apoptosis. Mice deficient for this gene bred on a BALB/c background developed dilated cardiomyopathy and died from congestive heart failure. These studies suggest that this gene product may also be important in T cell function and contribute to the prevention of autoimmune diseases.

 ADC Antibody

  • Overview
  • Humanized Anti-PDCD1 IgG1-kappa antibody, Pidilizumab
  • Generic name
  • Pidilizumab
  • Host animal
  • Mouse

 ADC Linker

  • 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.

 ADC payload drug

  • 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.
