TRK-851
RK-851 is a highly selective and orally active δ-opioid receptor antagonist, with a negative logarithm of the antagonist concentration (pA2) of 8.84. TRK-851 exhibits the selectivity for the δ receptor of more than 100 times higher than that for the μ or κ receptors. TRK-851 exhibits a potent antitussive effect in a rat model of capsaicin-induced cough. TRK-851 can be used for research on antitussive effects[1].
