This ADC product is comprised of an anti-IL6R 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.

- Target Entrez Gene ID
- 3570
- Overview
- This gene encodes a subunit of the interleukin 6 (IL6) receptor complex. Interleukin 6 is a potent pleiotropic cytokine that regulates cell growth and differentiation and plays an important role in the immune response. The IL6 receptor is a protein complex consisting of this protein and interleukin 6 signal transducer (IL6ST/GP130/IL6-beta), a receptor subunit also shared by many other cytokines. Dysregulated production of IL6 and this receptor are implicated in the pathogenesis of many diseases, such as multiple myeloma, autoimmune diseases and prostate cancer. Alternatively spliced transcript variants encoding distinct isoforms have been reported. A pseudogene of this gene is found on chromosome 9.
ADC Antibody
- Overview
- Humanized Anti-IL6R IgG1-kappa antibody, Tocilizumab
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.
