The synthetic preparation of the glucuronide adduct of Trocade(TM), a selec
tive inhibitor of the MMP collagenase, is described. This was achieved by p
reparation of the protected O-glucuronsyl hydroxylamine (9) and subsequent
coupling to the available carboxylic acid (7), followed by deprotection. Th
e synthetic material was identical to authentic isolated metabolite, which
confirmed that glucuronidation of Trocade(TM) occurs on the oxygen of the h
ydroxamic acid. (C) 2000 Published by Elsevier Science Ltd.
