Anti-FOLH1 (Capromab)-MC-Vc-PAB-DMEA-(PEG2)-duocarmycin SA ADC
Anti-FOLH1 (Capromab)-MC-Vc-PAB-DMEA-(PEG2)-duocarmycin SA ADC (ADC-W-1165)
This ADC product is comprised of an anti-FOLH1 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 type II transmembrane glycoprotein belonging to the M28 peptidase family. The protein acts as a glutamate carboxypeptidase on different alternative substrates, including the nutrient folate and the neuropeptide N-acetyl-l-aspartyl-l-glutamate and is expressed in a number of tissues such as prostate, central and peripheral nervous system and kidney. A mutation in this gene may be associated with impaired intestinal absorption of dietary folates, resulting in low blood folate levels and consequent hyperhomocysteinemia. Expression of this protein in the brain may be involved in a number of pathological conditions associated with glutamate excitotoxicity. In the prostate the protein is up-regulated in cancerous cells and is used as an effective diagnostic and prognostic indicator of prostate cancer. This gene likely arose from a duplication event of a nearby chromosomal region. Alternative splicing gives rise to multiple transcript variants encoding several different isoforms.
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.
