Monomethyl auristatin E (also known as MMAE; SGD-1010), a dolastatin 10 derivative, is a novel, synthetic and potent antimitotic/antitubulin agent which blocks the polymerization of tubulin, due to its high toxicity, it cannot be used as a drug itself; instead, it is linked to a monoclonal antibody (MAB) which directs it to the cancer cells. Vedotin, as used in the commercial drug Brentuximab vedotin, is MMAE plus the structure that connects it to the antibody (Brentuximab). In preclinical studies, both in vitro and in vivo, dolastatins—peptides found in the marine shell-less mollusc Dolabella auricularia—show strong activity against a variety of lymphomas, leukemia, and solid tumors. These peptides are the source of MMAE, a powerful antimitotic medication. When MMAE is used to treat Hodgkin lymphoma and other cancers, its potency can reach 200 times that of vinblastine, another antimitotic medication.

| ln Vitro |
In CD30+ cells, MMAE exhibits selective cytotoxicity when combined with cAC10. It also causes apoptosis, which results in G2/M-phase growth arrest and cell death. [1]
Anti-CD79b-vcMMAE exhibits strong and extensive activity on a wide range of NHL cell lines when combined with anti-CD79b antibody in vitro.[2] Hertuzumab-vc-MMAE can also be efficiently internalized and significantly kill tumor cells that overexpress HER2 when combined with anti-HER2 antibody.[3] |
| ln Vivo |
While free MMAE (0.36 mg/kg) does not exhibit any discernible antitumor activity, cAC10-vcMMAE (1 mg/kg, i.v.) causes total, long-lasting tumor regression in the Karpas 299 ALCL model.[1]
Anti-CD79b-vcMMAE (7 mg/kg, p.o.) notably causes a sustained total tumor remission in mouse xenograft models of NHL. [/2] |
| Cell Assay |
As directed by the manufacturer, the Alamar Blue dye reduction assay is used to quantify cytotoxicity. In short, right before cultures are added, a freshly prepared 40% (wt/vol) solution of Alamar Blue is added to complete media. Alamar Blue solution is added to cells to make up 10% of the culture volume ninety-two hours after the drug is exposed. A Fusion HT fluorescent plate reader (Packard Instruments, Meriden, CT) is used to measure dye reduction after 4 hours of incubation of the cells.

| Animal Protocol |
Mice: Female athymic nu/nu mice aged 6-8 weeks are given a 1:1 Matrigel and PBS solution subcutaneously injected into their thighs, containing 5×106 HCT-116 or PANC-1 cells. After administering ACPP-cRGD-MMAE intravenously (IV) or orally (IR) (6 nmoles/day, totaling 18 nmoles), the mice are given the treatment. Tumor tissue is then removed, paraffin embedded, formalin fixed, and stained with the appropriate antibodies. Using the UltraMap system, DAB is used as a chromagen and the primary antibody is used at a 1:250 dilution for visualization.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
