Org 27569 是一种有效的、选择性的、大麻素 CB1 受体变构调节剂。

Org 27569 is a potent, selective, allosteric modulator of cannabinoid CB1 receptor, significantly increases the binding of the CB1 receptor agonist [3H]CP 55,940 with pKb of 5.67; reduces food consumption in rats, produces CB1-independent hypophagic effects and does not affect the discriminative stimulus effects of anandamide (AEA).

Org 27569 enhances agonist (CP55940) binding, promotes agonist binding to CB1 yet inhibits agonist-induced G protein activation and blocks the agonist-induced conformational changes in TM6. Org 27569 inhibits agonist-induced TM6 movement in CB1 detected by a fluorescent probe on site 342. Org 27569 produces a significant, but saturable, increase in the level of specific [3H]CP 55,940 binding. Org 27569 (1 μM) inhibits electrically evoked contractions of the mouse vas deferens with the pEC50 and Emax being 8.66±0.11 and 77% (95% confidence limits, 70.6-82.7), respectively. In hCB1R cells, Org 27569 (1 and 10 μM) behaves as a weak inverse agonist producing a small but significant decrease in basal [35S]GTPγS binding. Org 27569 is less effective as an inhibitor of WIN55212-mediated inhibition of forskolin-stimulated cAMP production. Org 27569 induces a small but significant level of ERK1/2 phosphorylation with an Emax of 19% and pEC50 value of 8.55±0.99.

ORG 27569 (3.2 and 5.6 mg/kg, i.p.) significantly attenuates cocaine associated cue-induced reinstatement, cocaine priming-induced reinstatement, methamphetamine associated cue-induced reinstatement and methamphetamine priming-induced reinstatement in rat. Org27569 (30 mg/kg, i.p.) produces CB1-independent hypophagic effects and does not affect the discriminative stimulus effects of anandamide (AEA). Org27569 (100 μg intracerebroventricularly) does not affect the pharmacologic effects of systemically administered CP55,940 compared with vehicle.
