This chemotherapy agent is considered to have application in skincare products for its antiaging properties.

Ilomastat is a member of the hydroxamic acid class of reversible metallopeptidase inhibitors. The anionic state of the hydroxamic acid group forms a bidentate complex with the active site zinc.[5]

Examples of enzymes that ilomastat inhibit include rabbit MMP9,[6] thermolysin,[2] peptide deformylase,[7] and anthrax lethal factor endopeptidase (LF) produced by the bacterium Bacillus anthracis.[8][9]
