Anti-CD19 (B496)-MCC-DM1 ADC (ADC-W-614)

This ADC product is comprised of an anti-CD19 monoclonal antibody (B496) conjugated via a MCC linker to DM1. The DM1 is targeted to certain cancers by immunerecognition and delivered into cancer cells via receptor mediated endocytosis. Within the cell, DM1 binds to tubulins, interrupts microtubule dynamics, and subsequently, induces cell death.

 ADC Target

  • Name
  • CD19
  • Alternative Names
  • CD19; CD19 molecule; B4; CVID3; B-lymphocyte antigen CD19; differentiation antigen CD19; T-cell surface antigen Leu-12; B-lymphocyte surface antigen B4;
  • Target Entrez Gene ID
  • 930
  • Overview
  • Lymphocytes proliferate and differentiate in response to various concentrations of different antigens. The ability of the B cell to respond in a specific, yet sensitive manner to the various antigens is achieved with the use of low-affinity antigen receptors. This gene encodes a cell surface molecule which assembles with the antigen receptor of B lymphocytes in order to decrease the threshold for antigen receptor-dependent stimulation.

 ADC Linker

  • Name
  • MCC (Maleimidomethyl cyclohexane-1-carboxylate)
  • Description
  • Noncleavable linkers, is considered noncleavable-meaning linker cleavage, and payload release does not depend on the differential properties between the plasma and some cytoplasmic compartments. Instead, the release of the cytotoxic drug is postulated to occur after internalization of the ADC via antigen-mediated endocytosis and delivery to lysosomal compartment, where the antibody is degraded to the level of amino acids through intracellular proteolytic degradation.

 ADC payload drug

  • Name
  • DM1 (N2’-Deacetyl-N2’-(3-mercapto-1-oxopropyl)maytansine)
  • Description
  • Derived from Maytansinoid,a group of cytotoxins structurally similar to rifamycin, geldanamycin, and ansatrienin. The eponymous natural cytotoxic agent maytansine is a 19-member lactam (ansa
    macrolide) structure originally isolated from the Ethiopian shrub Maytenus ovatus. Maytansinoids can bind to tubulin at or near the vinblastine-binding site, which interfere the formation of microtubules and depolymerize already formed microtubules, inducing mitotic arrest in the intoxicated cells.
