GM6001 MMP Inhibitor Powder

specificity:GM6001 MMP inhibitor, also known as Ilomastat or N-[(2R)-2-(hydroxamidocarbonylmethyl)-4-methylpentanoyl]-L-tryptophan methylamide, is a potent inhibitor of collagenases. Molecular weight: 388.47

Reported Ki values are as follows (see Galardy Ref):

Human MMP-1 (Fibroblast collagenase): 0.4 nM

Human MMP-3 (Stromelysin): 27 nM

Human MMP-2 (72 kDa gelatinase): 0.5 nM

Human MMP-8 (Neutrophil collagenase): 0.1 nM

Human MMP-9 (92 kDa gelatinase): 0.2 nM

Typical working dilution for use in cultured cells is 10-25 μM. {1mg/ml solution in DMSO equals 2.57 mM}. GM6001 will precipitate from aqueous solutions exceeding 100μM. Aqueous dilutions should be performed using low salt buffers to prevent precipitation of GM6001 from solution (Recommended dilution buffer: 50 mM Tris pH7.5, 150 mM NaCl, and 20 mM CaCl2.2H20). It is recommended that the concentration of GM6001 in aqueous working solutions is determined upon dilution and confirmed prior to each use. Additional Application information:
Use in vivo
Typical dosage for GM6001 in animals is 50-100mg/kg body weight. It is generally administered IP every day or every other day. It is thought to cross the blood brain barrier since studies have shown it effectiveness in MS models.

If delivered by I.V. the half life in an animal is approximate an hour so it will have to be administered quite often. Thus the preferred way is to deliver the drug by I.P as a suspension in water or saline. The half life does not change but because it is dissolving in the animal′s system slowly, administration is not done as frequently. It has to be redelivered every other day or so. It can also be delivered subcutaneously in a saline suspension. The drug will precipitate as stay as a mass within the tissue, but surprisingly enough does get into the animal system to be effective.

Solubility
Soluble up to at least 400 mg/mL in DMSO. It can then be diluted in water and must be mixed very quickly to avoid precipitation.

Stability
At a concentration of 1mM (0.1mM is preferred), GM6001 decomposes at the rate of 1% per month at 4°C. At 37°C this increases to 1% per day. At -20°C it is quite stable, and as a solid very highly stable
Low salt buffers are recommended as diluents to reduce precipitation. Diluted solutions should never be frozen.

Concentration of the stock solution should be periodically determined by absorbance at 280 nm.

The GM6001 MMP Inhibitor Powder controls the biological activity of MMP. This small molecule/inhibitor is primarily used for Biochemicals applications.

Inhibitor Type: Protease Inhibitors

Protein Target: Interstitial collagenase

Lyophilized, reconstitute in DMSO (1-5 mg/ml). Other organic solvents (ethanol) have also been used (Galardy et al., 1994).

some batches can be brown when hydrated; brown color does not influence inhibition ability; in solution GM6001 ranges from clear to brown

Maintain lyophilized form at 2-8º C for up to one year from date of receipt. If reconstitution is in DMSO, material is soluble to at least 400 mg/mL and storage is recommended in usable aliquots at -20 º C. Avoid repeated freeze/thaw cycles. If reconstituting in aqueous solution, store short term in undiluted aliquots at 2-8º C. See stability information for further detail.
