RB 101 hydrochloride
Based on 1 Customer Validation
RB 101 hydrochloride is a blood-brain barrier-crossing prodrug as well as aminopeptidase N and neutral endopeptidase-24.11 inhibitor. RB 101 hydrochloride blocks enkephalin breakdown, elevates extracellular enkephalin levels and activate δ-opioid receptor and dopamine D1 receptor. RB 101 hydrochloride can be used for the research of pain, depressive syndromes, and diabetic neuropathy.

体外実験
体内実験
RB 101 (5-20 mg/kg; i.v.; single administration) hydrochloride potentiates stress-induced analgesia in mice, reaching 85% analgesia at 5 mg/kg when combined with warm-water swim stress[1].
RB 101 (1.25-10 mg/kg; i.v.; single slow injection) hydrochloride induces a dose-dependent, long-lasting increase in spontaneous motor activity in mice via δ opioid and dopamine D1 receptor stimulation[2].
RB 101 (2.5-10 mg/kg; i.v.; single slow injection) hydrochloride dose-dependently attenuates conditioned suppression of motility in shocked mice and increases striatal dopamine turnover, via δ opioid and dopamine D1 receptor stimulation[2].
RB 101 (2.5-10 mg/kg; i.v.; single slow injection (20 s); 10 min before testing) hydrochloride significantly reduces immobility time in the mouse forced swim test via δ opioid and dopamine D1 receptor stimulation[2].
RB 101 (5-40 mg/kg; i.v.) hydrochloride produces dose-dependent, μ- and δ-opioid receptor-mediated antinociception in Streptozocin (HY-13753)-induced diabetic rats with neuropathic pain, completely suppressing mechanical hyperalgesia at doses of 20 and 40 mg/kg i.v.[3].

-
Animal Model:Male albino mice (Depre, France; 20-22 g)[1]
-
Dosage:2.5 mg/kg; 5 mg/kg; 10 mg/kg; 20 mg/kg; 40 mg/kg
-
Administration:i.v.; single administration
-
Result:Induced a dose-dependent reduction in [3H]diprenorphine binding: 5 mg/kg caused 20% displacement, 10 mg/kg caused 30% displacement (plateau effect), with no additional displacement at 20 mg/kg.
Induced a non-significant increase in jump latency at 5 mg/kg.
Produced statistically significant analgesia relative to controls at 10 mg/kg, 20 mg/kg, and 40 mg/kg, with analgesia percentages increasing with dose.
-
Animal Model:Male albino mice (Depre, France; 20-22 g; forced warm-water swim stress model)[1]
-
Dosage:5 mg/kg; 20 mg/kg
-
Administration:i.v.; single administration
-
Result:Combined with stress induced 85% analgesia at 5 mg/kg (vs. 48% analgesia from stress alone), and this combined analgesia was blocked by naloxone but not by naltrindole.
Combined with stress caused 45% displacement of [3H]diprenorphine relative to unstressed controls at 5 mg/kg, while 20 mg/kg combined with stress caused 43% displacement relative to unstressed controls.
-
Animal Model:Swiss albino mice (male, 20-22 g for spontaneous motor activity and forced swim tests; ~30 g, 8 weeks old for conditioned suppression of motility test)[2]
-
Dosage:1.25 mg/kg; 2.5 mg/kg; 5 mg/kg; 10 mg/kg
-
Administration:i.v.; single slow injection
-
Result:Induced a dose-dependent increase in locomotor activity, with effects peaking between 5-10 min post-injection.
Remained significant at 15 and 20 min post-injection at 10 mg/kg.
Produced a significant cumulative increase in motor activity (linear locomotion + rears) over 10 and 20 min at 5 mg/kg, which was antagonized by pre-treatment with naltrindole (0.1 mg/kg s.c.) and SCH 23390 (0.07 mg/kg s.c.), but not sulpiride (25 mg/kg i.p.).

Animal Model:Swiss albino mice (male, ~30 g, 8 weeks old)[2]
-
Dosage:2.5 mg/kg; 5 mg/kg; 10 mg/kg
-
Administration:i.v.; single slow injection
-
Result:Did not alter locomotor activity at 2.5 and 5 mg/kg, but increased activity at 10 mg/kg in non-shocked mice.
Dose-dependently reduced conditioned motility suppression at 5 and 10 mg/kg in shocked mice.
Effect of 5 mg/kg was antagonized by pre-treatment with naltrindole (0.1 mg/kg s.c.) and SCH 23390 (0.07 mg/kg s.c.), but not sulpiride (25 mg/kg i.p.).
Significantly increased striatal DOPAC/DA and HVA/DA ratios to 0.108 and 0.100, respectively, in shocked mice treated with 5 mg/kg, an effect blocked by naltrindole.

-
Dosage:2.5 mg/kg; 5 mg/kg; 10 mg/kg
-
Administration:i.v.; single slow injection
-
Result:Significantly shortened the duration of immobility in the forced swim test at 5 and 10 mg/kg.
Effect of 5 mg/kg was antagonized by pre-treatment with naltrindole (0.1 mg/kg s.c.) and SCH 23390 (0.07 mg/kg s.c.), but not sulpiride (25 mg/kg i.p.).

Animal Model:Sprague-Dawley (male, 300 g, Streptozocin-induced neuropathic pain)[3]
-
Dosage:5 mg/kg; 10 mg/kg; 20 mg/kg; 40 mg/kg
-
Administration:i.v.
-
Result:Produced a dose-dependent antinociceptive effect on mechanical hyperalgesia, with 20 and 40 mg/kg doses completely suppressing diabetes-induced hyperalgesia (P<0.001).
Achieved a maximal vocalization threshold elevation of +294 g (+178% of predrug score) at 20 minutes with 40 mg/kg dose, which was not significantly different from the maximal effect of 20 mg/kg.
Had a short duration of action (20 minutes) with 5 mg/kg dose, while 10, 20, and 40 mg/kg doses lasted 60 minutes.
Showed a ceiling effect at 40 mg/kg confirmed by AUC values.
Produced a significant increase in withdrawal threshold for mechanical allodynia only with 40 mg/kg dose, with a maximal increase of +8.3 g at 20 minutes (P<0.01), lasting 20 minutes.
Did not significantly affect tail immersion reaction time for thermal allodynia at any dose.
Had its antinociceptive effect at 20 mg/kg completely abolished by pretreatment with 0.5 mg/kg i.v. naloxone or 1 μg/rat i.t. naltrindole.
