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.{{cite web | url = http://merops.sanger.ac.uk/cgi-bin/smi_summary?mid=J16.402 | archive-url = https://archive.today/20121223040118/http://merops.sanger.ac.uk/cgi-bin/smi_summary?mid=J16.402 | url-status = dead | archive-date = December 23, 2012 | title = Small-molecule inhibitor J16.402: galardin | publisher = Wellcome Trust Sanger Institute | work = MEROPS - the Peptidase Database | date = 2010-09-07 | access-date = 2010-10-04 }}
