MMAF

SKU: orb1304379

Description

MonoMethyl auristatin F (MMAF) is a potent antimitotic agent that disrupts microtubule dynamics by inhibiting tubulin polymerization, thereby arresting cell division. This mechanism makes it a valuable payload in antibody-drug conjugates (ADCs) for cancer research, with applications in both in vitro cytotoxicity assays and in vivo xenograft studies.

Bioactivity

• Target IC50:
  H3397 cells:105 nM.
• In Vivo:
  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.

• In Vitro:
  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.

• Cell Research:
  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.
