Anti-IGHE (Ligelizumab)-MC-Vc-PAB-DMEA-(PEG2)-duocarmycin SA ADC
Anti-IGHE (Ligelizumab)-MC-Vc-PAB-DMEA-(PEG2)-duocarmycin SA ADC (ADC-W-1285)
This ADC product is comprised of an anti-IGHE 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.
Constant region of immunoglobulin heavy chains. Immunoglobulins, also known as antibodies, are membrane-bound or secreted glycoproteins produced by B lymphocytes.
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
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.
