Anti-TNFSF11 (Denosumab)-MC-Vc-PAB-DMEA-(PEG2)-duocarmycin SA ADC
Anti-TNFSF11 (Denosumab)-MC-Vc-PAB-DMEA-(PEG2)-duocarmycin SA ADC (ADC-W-2239)
This ADC product is comprised of an anti-TNFSF11 monoclonal antibody conjugated via a MC-Vc-PAB-DMEA-(PEG2) linker to duocarmycin SA. The duocarmycin SA is targeted to certain cancers by immunerecognition and delivered into cancer cells via receptor mediated endocytosis. Within the cell, duocarmycin SA binds to DNA, causes DNA damage.

This gene encodes a member of the tumor necrosis factor (TNF) cytokine family which is a ligand for osteoprotegerin and functions as a key factor for osteoclast differentiation and activation. This protein was shown to be a dentritic cell survival factor and is involved in the regulation of T cell-dependent immune response. T cell activation was reported to induce expression of this gene and lead to an increase of osteoclastogenesis and bone loss. This protein was shown to activate antiapoptotic kinase AKT/PKB through a signaling complex involving SRC kinase and tumor necrosis factor receptor-associated factor (TRAF) 6, which indicated this protein may have a role in the regulation of cell apoptosis. Targeted disruption of the related gene in mice led to severe osteopetrosis and a lack of osteoclasts. The deficient mice exhibited defects in early differentiation of T and B lymphocytes, and failed to form lobulo-alveolar mammary structures during pregnancy. Two alternatively spliced transcript variants have been found.

Overview
Human Anti-TNFSF11 IgG2 antibody, Denosumab
Generic name
Denosumab
Host animal
Human
ADC Linker
Name
MC-Vc-PAB-DMEA-(PEG2)
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
duocarmycin SA
Description
Duocarmycins SA belong to the minor-groove-binding DNA-alkylating agents (DNA MGBA). The natural duocarmycins are isolated from the culture broth of Streptmyces sp and a series of derivatives has also been synthesized.
