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.

The dynamic regulation of signal transduction at plasma membrane microdomains remains poorly understood due to limitations in current experimental approaches. Genetically encoded biosensors based on fluorescent resonance energy transfer (FRET) can provide high spatiotemporal resolution for imaging cell signaling networks.
