In vitro GM6001 inhibits human skin fibroblast collagenase with Ki of 0.4 nM when assayed with a synthetic thio ester substrate at pH 6.5, with 50-fold selectivity over two bacterial enzymes, thermolysin and Pseudomonas aeruginosa elastase. [1] GM 6001 (0.1 nM - 10 nM) inhibits gelatinase A and gelatinase B produced by T-cells, thus inhibits T-cell homing. [2]
In vivo Topical application of GM6001 (400 μg/ml) prevents corneal ulceration after severe alkali injury. [3] In rabbit model after stenting, GM6001 significantly inhibits intimal hyperplasia and intimalcollagen content, and it increases lumen area in stented arteries without effects on proliferation rates.

Protocol(Only for Reference)

Kinase Assay:


Collagenase assay Collagenase assay uses the synthetic thiol ester substrate Ac-Pro-Leu-Gly-SCH(i-Bu)CO-Leu-Gly-OEt at pH 6.5. The collagenase concentration is 1-2 nM, and the substrate concentrations are from 0.1 to 0.7 nM. Km is found to vary between 1.5 and 4 mM.

Animal Study:

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
