| Description | Marimastat (BB2516) (BB-2516) is a potent, broad spectrum matrix metalloprotease (MMP) inhibitor. 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). |
| Targets & IC50 | MMP2:6 nM, MMP14:9 nM, MMP9:3 nM, MMP1:5 nM, MMP7:13 nM |
| In vitro | Marimastat (BB-2516) is a broad-spectrum MMPI with an enzyme inhibitory spectrum very similar to batimastat. [1] Marimastat inhibits CD30 shedding in Karpas 299 cells with an IC50 of 1 microM [2] and also inhibits LPS-induced soluble TNF-alpha production in a dose-dependent manner. The enzyme, tumor necrosis factor alpha convertase (TACE), reported to be closely related to matrix metalloproteinases, is responsible for the processing of pro-TNFalpha to TNFalpha and is specifically inhibited by Marimastat with an IC50 of 3.8 nM.[3] |
| In vivo | Marimastat has a favorable pharmacokinetic profile in humans, as it is almost completely absorbed after oral administration, with a high and predictable bioavailability and a half-life of approximately 15 hr (justifying twice a day dosing), making it a much more palatable treatment option for Clinicalal trials than batimastat. Marimastat is rapidly metabolized in rodents, undergoing a very high first-pass effect, making testing of marimastat in rodents difficult, as sustained plasma concentrations in this species are difficult to obtain.

| Kinase Assay | Compounds 1, 2, 7-9 and 11-16 are pre-incubated with MMP-1 or MMP-3 (10 nM) at different concentrations (0-10 μM) in a mixture of Tris-HCl (50 mM, pH 7.5), NaCl (150 mM), CaCl2 (10 mM), NaN3 (0.02%) and Brij-35 (0.05%) for 1 hour at 37°C. Residual activity is measured using the fluorogenic MMP substrate (2 μM) by fluorescence increase (emission at 393 nm and excitation at 325 nm) on a fluorescence plate reader. The data are fitted to the tight binding inhibitor equation: v=[(E-I-k+[(E-I-k)2+4Ek]1/2)/(2E)], where v is the velocity of the reaction, E is the enzyme concentration, I is the initial inhibitor concentration, and k is the apparent inhibition constant, using the software Prism. |

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 
10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH2O , the resulting working solution concentration would be 2 mg/mL.Dissolve 2 mg of the compound in 100 μL DMSO to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
1) Add 100 μL of the DMSO stock solution to 400 µL PEG300 and mix thoroughly until the solution becomes clear.
2) Add 50 µL Tween 80 and mix well until fully clarified.
3) Add 450 µL Saline,PBS or ddH2O and mix thoroughly until a homogeneous solution is obtained.
