TILIDINE is a low to medium potency opioid analgesic. It is metabolized to its active metabolites, nortilidine and bisnortilidine. Its analgesic activity is largely exerted through nortilidine which is a potent agonist at Mu opioid receptors.

Sample Use Guides

In Vitro Use Guide

The selectivity of tilidine and nortilidine for human opioid and opioid-like receptors stably expressed in CHO-K1 cells, using the inhibition of the forskolin (FK)-induced accumulation of cAMP as the endpoint was measured. In cells expressing the Mu opioid receptor, tilidine and nortilidine inhibited cAMP accumulation with IC50 of 11 microM and 110 nM, respectively.
