D8-MMAF hydrochloride is a deuterated form of MMAF hydrochloride, which is a microtubule disrupting agent.

MMAF shows in vitro cytotoxicity against a panel of cell lines. The IC₅₀ values for Karpas 299, H3396, 786-O and Caki-1 are 119, 105, 257, and 200 nM, respectively. Targeted MMAF is much more potent than the free drug, and that cAC10 conjugates of MMAF display pronounced activities. On a molar basis, the cAC10-L1-MMAF₄ is an average of over 2200-fold more potent than free MMAF and is active on all the CD30-positive cell lines tested^[1].

The maximum tolerated dose in mice of MMAF (>16 mg/kg) is much higher than MMAE (1 mg/kg). cAC10-L1-MMAF₄ has an MTD of 50 mg/kg in mice and 15 mg/kg in rats. The corresponding cAC10-L4-MMAF₄ ADC was much less toxic, having MTDs in mice and rats of >150 mg/ kg and 90 mg/kg in rats, respectively^[1].

Cells are treated with serial dilutions of test molecules and incubated 4-6 days depending on cell line. Assessment of cellular growth and data reduction to generate IC₅₀ values is done using Alamar Blue dye reduction assay^[1].

Mice: When subcutaneous Karpas 299 tumor size reaches 300 mm³, three animals per group receives one injection of 10 mg antibody component/kg body weight of either cAC10-L1-MMAF₄ or cBR96-L1-MMAF₄ intravenously. Tumors are then removed and placed in optimal cutting temperature compound, and 5 μm-thin frozen tissue sections are stained using immunohistochemistry evaluation^[1].
