A two-component initiator system having accelerators for curing polymerizable materials comprising the following components: (a) a hydroperoxide compound containing one or more hydroperoxide groups that are bound to a tertiary carbon; (b) a thiourea derivative; and (c) as accelerator, a copper compound which is soluble in the preparation is preferably free of amine and is particularly suited for polymerizable dental compositions.

Ureido and thioureido derivatives of 2-acetamido-2-deoxy-beta-D-glucose, 1-amino-1-deoxy-D-glucitol and 2-(2-aminoethoxy)ethanol were prepared as N-acetyl-beta-D-hexosaminidase (NAHase) inhibitors and were evaluated on Trichomonas vaginalis NAHase. Although none showed complete inhibition of the enzyme at 100 microM, 1-amino-1-deoxy-D-glucitol derivatives acted as competitive inhibitors of the NAHase
