In vitro	Ilomastat (GM6001) inhibits human skin fibroblast collagenase with K_i 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. This compound (0.1 nM - 10 nM) inhibits gelatinase A and gelatinase B produced by T-cells, thus inhibits T-cell homing.
Kinase Assay	Collagenase assay
Kinase Assay	Ilomastat (GM6001) is assayed using 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. K_m is found to vary between 1.5 and 4 mM.
In vivo	Topical application of Ilomastat (GM6001) (400 μg/ml) prevents corneal ulceration after severe alkali injury. In rabbit model after stenting, it significantly inhibits intimal hyperplasia and intimalcollagen content, and increases lumen area in stented arteries without effects on proliferation rates.
