Description

WIN-55212-2 mesylate is a CB1 agonist (cannabinoid receptor agonist). WIN-55212-2 impairs contextual fear conditioning through the activation of CB1 cannabinoid receptors. Win-55212-2 attenuates leukocyte/endothelial interactions in an experimental autoimmune encephalomyelitis model. WIN-55212-2 inhibits neurogenic inflammations in airway tissues.

How to use

In Vitro:

WIN-55212-2 mesylate is more potent in CHO-CB2 cells than in CHO-CB1 cells by a factor of 6O. WIN-55212-2 mesylate has no effect on arachidonic acid release in CHO-CB2 or control CHO cells. WIN-55212-2 mesylate fails to stimulate any increase in intracellular Ca2+ up to 10 μM. In primary cultures of rat cerebral cortex neurons, WIN-55212-2 mesylate (0.01--100 nM) increases extracellular glutamate levels, displaying a bell-shaped concentration-response curve. The facilitatory effect of WIN-55212-2 mesylate (1 nM) is fully counteracted by SR141716A (10 nM), by the replacement of the normal Krebs Ringer-bicarbonate buffer with a low Ca2+ medium (0.2 mM) and by the IP(3) receptor antagonist xestospongin C (1 μM). WIN-55212-2 mesylate evokes CGRP release from TG neurons in vitro (EC50=26 μM) in a concentration- and calcium-dependent manner. WIN-55212-2 mesylate-2 neither inhibits capsaicin-evokes CGRP release nor does it inhibit forskolin-, isoproteranol- or prostaglandin E2-stimulated cAMP accumulation. WIN-55212-2 mesylate significantly inhibits (EC50=1.7 μM) 50 mm K+-evoked CGRP release by approximately 70%. WIN-55212-2 mesylate inhibition of 50 mm K+-evoked CGRP release is not reversed by antagonists of cannabinoid type 1 (CB1) receptor, but is mimicks in magnitude and potency (EC50=2.7 μM) by its cannabinoid-inactive enantiomer WIN-55212-2 mesylate-3.

In Vivo:

In the prefrontal cortex WIN-55212-2 mesylate (0.1 and 1 mg/kg i.p.) increases dialysate glutamate levels from of the awake rat, while the lower (0.01 mg/kg) and the higher (2 mg/kg) doses are ineffective. Furthermore, the WIN-55212-2 mesylate (0.1 mg/kg)- induced increase of dialysate glutamate levels is counteracted by pretreatment with the selective CB(1) receptor antagonist SR141716A (0.1 mg/kg, i.p.) and by the local perfusion with a low-calcium Ringer solution (Ca2+ 0.2 mM)[2]. WIN-55212-2 mesylate (0.5, 1, 3, 5, 10 and 15 mg/kg, i.p.) does not alter the seizure threshold at low doses, while higher doses of the drug significantly increases the threshold in a dose-dependent manner. The anticonvulsant effect of WIN-55212-2 mesylate, which is observed with doses as high as 5 mg/kg, can be observed with doses as low as 0.5 mg/kg in groups pre-treated with 20 mg/kg of pioglitazone.
