Application

Naltriben methanesulfonate hydrate has been used in the assessment of parasite growth and evaluation of growth inhibition. It has also been used to understand the action of deltorphin-II in exhibiting its antimalarial effect.

Biochem/physiol Actions

Naltriben methanesulfonate is a highly selective δ2 opioid receptor antagonist. The relative ability of the delta antagonists benzylidenenaltrexone and naltriben to inhibit DPDPE-stimulated [35S]GTPgammaS binding suggests that the opioid receptor is of the delta-2 subtype. Ligand binding assays demonstrates biphasic binding of the antagonist to the single receptor type. [35S]GTPgammaS binding is also stimulated by [D-Ser2,Leu5,Thr6]enkephalin > deltorphin II = DPDPE = etorphine > levallorphan = diprenorphine = nalorphine = naltrindole.
