| In Vitro | Opioid drugs exert a wide spectrum of physiological and behavioral effects. These effects are mediated via membrane-bound receptors, of which the best characterized are the kappa, delta, and mu receptors[1]. Naltrindole inhibits the proliferation of cultured human U266 MM cells in a time- and dose-dependent manner with an EC50 of 16 μM. Treatment of U266 cells with naltrindole significantly decreases the level of the active, phosphorylated form of the kinases, extracellular signal-regulated kinase and Akt, which may be related to its antiproliferative activity[2]. Naltrindole inhibits growth and induces apoptosis in the three characteristic SCLC cell lines, NCI-H69, NCI-H345, and NCI-H510. Naltrindole treatment reduces constitutive phosphorylation of Akt/PKB on serine 473 and threonine 308 in cells and also its downstream effectors glycogen synthase kinase-3β and the Forkhead transcription factors AFX and FKHR[3]. |
| In Vivo | Naltrindole significantly decreases tumor cell volumes in human MM cell xenografts in severe combined immunodeficient mice[2]. In mice, naltrindole at 20 mg/kg s.c. antagonizes the δ-selective agonist effect of [D- Ser, Leu, Thr]enkephalin (DSLET) without blocking the antinociceptive effect of morphine or U50488H. Naltrindole is the only highly selective δ antagonist that is active upon peripheral administration[4]. Acute naltrindole induces significant decreases in external and total ambulation (horizontal activity) and rearing behaviour (vertical activity), as well as a significant increase in grooming frequency. In animals chronically treated with naltrindole there is an increase in total ambulation one day after the discontinuation of the treatment[5]. |
| Cell Assay | U266 cells are plated in 96-well plates at 2000 cells per well in 100 μL of RPMI 1640 medium, supplemented with 10% fetal bovine serum, 100 U/mL penicillin, and 100 μg/mL streptomycin sulfate. Cells are incubated in quadruplicate in the presence of the various antineoplastic agents to construct dose-response curves, alone or in combination with various doses of naltrindole. At the end of the incubation 10 μL of WST-1 cell proliferation reagent is added to each well, and the plates are returned to the incubator for 1 h. Absorbance is then measured[2]. |
| Animal Admin | Rats: Effects of neonatal naltrindole treatments on open field activity is tested in 20-day old rats. The animals are injected chronically with saline or naltrindole (1 mg/kg, s.c.) (from birth to day 19), and 1 day after the discontinuation of this treatment are studied for the acute effects of naltrindole (1 mg/kg, i.p.)[5]. Mice: Naltrindole is dissolved in distilled water to make a 3 mg/mL solution, and mice are injected with 10 mL/kg daily. Human RPMI 8226 multiple myeloma cells are inoculated subcutaneously into both flanks of SCID mice (10 million cells per flank). After 8 days, 12 mice are divided into two groups of six mice each: vehicle-injected and naltrindole-injected (30 mg/kg). Animals are dosed daily for 36 days, and body weights and xenograft tumors are measured twice a week with a digital caliper[2]. |
