Trap-101 hydrochloride is a potent, selective and competitive antagonist of NOP receptors over classical opioid receptors. Trap-101 stimulates GTPγ35S binding to CHOhNOP membranes with pKi values of 8.65, 6.60, 6.14 and <5 for NOP, μ-, κ-, and δ-opioid receptors, respectively. Trap-101 attenuates motor deficits in a rat model of parkinson's disease and can be used for the research of nervous system diseases[1].

IC50 & Target

pKi: 8.65 (NOP receptor); 6.60 (μ-opioid receptor); 6.14 (κ-opioid receptor); < 5 (δ-opioid receptor)[1]

In Vitro

Trap-101 hydrochloride (3, 30, and 300 nM) is inactive per se up to 10 μM, while in the range 3-300 nM, it produces a concentration dependent rightward shift of the concentration-response curve to N/OFQ without modifications of the maximal response to the agonist. Receptor binding affinities of Trap101 (pKi values) at recombinant human NOP, and classical opioid receptors expressed in CHO cell membranes are 8.65, 6.60, 6.14 and < 5 for NOP, μ-, κ-, and δ-opioid receptors respectively[1].

In Vivo

Trap-101 hydrochloride (10-30 mg/kg; detected after 90 min) changes motor activity in naïve rats, it causes a delayed increase in the immobility time in the bar test at 30 mg/kg, Moreover, it increased stepping activity and rotarod performance at 10 mg/kg and reduces them at 30 mg/kg[1].
6-OHDA lesioning produces motor asymmetry mostly affecting the contralateral paw and overall reduced motor performance. Trap-101 hydrochloride (intraperitoneal injection; 10-30 mg/kg; detected after 90 min) alleviates akinesia/bradykinesia and improves overall gait ability in hemiparkinsonian rats, being effective starting at 1 mg/kg and without worsening motor deficit at 30 mg/kg[1].

Animal Model: 6-OHDA hemilesioned rats[1]
Dosage: 10-30 mg/kg
Administration: Intraperitoneal injection; 10-30 mg/kg; detected after 90 min
Result: Attenuated parkinsonian-like motor deficits in rat.
