Marimastat (BB2516) is a broad spectrum and orally bioavailable inhibitor of MMPs, with potent activity against MMP-9 (IC₅₀=3 nM), MMP-1 (IC₅₀=5 nM), MMP-2 (IC₅₀=6 nM), MMP-14 (IC₅₀=9 nM) and MMP-7 (IC₅₀=13 nM), used in the treatment of cancer. Marimastat (BB2516) is an angiogenesis and metastasis inhibitor, which limits the growth and production of blood vessels. As an antimetatstatic agent it prevents malignant cells from breaching the basement membranes^[1][2]. IC50 & Target: IC50: 3 nM (MMP-9), 5 nM (MMP-1), 6 nM (MMP-2), 9 nM (MMP-14), 13 nM (MMP-7) In Vitro: Marimastat (BB2516) (1 uM) shows inhibition of vascular outgrowth, and selectively affects angiogenesis^[3]. In Vivo: Animals receiving chemoradiation + Marimastat (BB2516) (8.7 mg/kg) have statistically significant delayed growth, compared to animals receiving chemoradiation alone. Marimastat (BB2516) may work in combination with chemotherapy and radiation to inhibit tumor growth^[4].
