Biological Activity

Description MMAE (Monomethyl auristatin E) is a synthetic antineoplastic agent. It is also a microtubule-disrupting agent .
In vitro

When coupled to cAC10, MMAE shows selective cytotoxicity in CD30+ cells, and induces G2/M-phase growth arrest and cell death through the induction of apoptosis. [1]

When coupled to anti-CD79b antibody, anti–CD79b-vcMMAE has very potent and broad activity across a large panel of NHL cell lines in vitro. [2]

When coupled to anti-HER2 antibody, hertuzumab-vc-MMAE can also be effectively internalized and potently kill HER2 over-expressing tumor cells. [3]

In vivo

In the Karpas 299 ALCL model, cAC10-vcMMAE (1 mg/kg, i.v.) induces complete, durable tumor regression, while free MMAE (0.36 mg/kg) doesn’t produce detectable antitumor activity. [1]

In mouse xenograft models of NHL, anti–CD79b-vcMMAE (7 mg/kg, p.o.) strikingly results in sustained complete tumor remission. [2]

Protocol (from reference)

Cell Assay:

[1]

  • Cell lines

    CD30+ Karpas 299 cells

  • Concentrations

    ~1000 ng/mL

  • Incubation Time

    96 h

  • Method

    Cytotoxicity is measured using Alamar Blue dye reduction assay according to the manufacturer's directions. Briefly, a 40% solution (wt/vol) of Alamar Blue is freshly prepared in complete media just before cultures are added. Ninety-two hours after drug exposure, Alamar Blue solution is added to cells to constitute 10% culture volume. Cells are incubated for 4 hours, and dye reduction is measured on a Fusion HT fluorescent plate reader (Packard Instruments, Meriden, CT).
