Animal experiment: |
In experiment 1, different doses of WIN 55,212-2 (0.5, 1, 3, 5, 10 and 15 mg/kg) are injected 60 min prior to the determination of clonic seizure threshold induced by intravenous administration of PTZ solution. Control animals receive the same volume of the vehicle (1% aqueous solution of DMSO). The doses and time point are chosen on the basis of pilot studies. In experiment 2, in order to confirm the anticonvulsant effects of pioglitazone, different doses (10, 20, 40 and 80 mg/kg) are administered 4 h prior to PTZ in distinct groups of mice. The corresponding control groupreceive the appropriate vehicle (CMC 1%) at the same time point. In experiment 3, The additive anti epileptic effects of WIN 55,212-2 and pioglitazone are examined; mice receive acute administration of pioglitazone (10 or 20 mg/kg) 3 h before WIN 55,212-2 (0.5 or 1 mg/kg) and 4 h before PTZ. |

(+)-WIN 55,212-2 (mesylate) is a potent aminoalkylindole cannabinoid (CB) receptor agonist with Ki values of 62.3 and 3.3 nM for human recombinant CB1 and CB2 receptors, respectively.1 In primary cultures of rat cerebral cortex neurons, (+)-WIN 55,212-2 (mesylate) (0.01-100 nM) increases extracellular glutamate levels, displaying a bell-shaped concentration-response curve.2 This effect is fully counteracted by rimonabant at a concentration of 10 nM, by decreasing Ca2+ concentrations below 0.2 mM, or by the IP3 receptor antagonist xestospongin C at a concentration of 1 ?M. (+)-WIN 55,212-2 (mesylate) induces release of the proinflammatory neuropeptide CGRP from trigeminal ganglion (TG) neurons in a calcium-dependent manner with an EC50 value of 26 ?M.3

Transdermal permeation of WIN 55,212-2 and CP 55,940 in human skin in vitro
Int J Pharm 2004 Jun 18;278(1):173-80.PMID:15158959DOI:10.1016/j.ijpharm.2004.03.009.
Synthetic cannabinoids have a promising future as treatments for nausea, appetite modulation, pain, and many neurological disorders. Transdermal delivery is a convenient and desirable dosage form for these drugs and health conditions. The aim of the present study was to investigate the in vitro transdermal permeation of two synthetic cannabinoids, WIN 55,212-2 and CP 55,940. Transdermal flux, drug content in the skin, and lag times were measured in split-thickness human abdominal skin in flow-through diffusion cells with receiver solutions of 4% bovine serum albumin (BSA) or 0.5% Brij 98. Differential thermal analysis (DSC) was performed in order to determine heats of fusion, melting points, and relative thermodynamic activities. The in vitro diffusion studies in 0.5% Brij 98 indicated that WIN 55,212-2 diffuses across human skin faster than CP 55,940. The WIN 55,212-2 skin disposition concentration levels were also significantly higher than that of CP 55,940. Correspondingly, CP 55,940 was significantly metabolized in the skin. WIN 55,212-2 flux and skin disposition were significantly lower into 4% BSA than into 0.5% Brij 98 receiver solutions. There was no significant difference in the flux, lag time, and drug content in the skin of CP 55,940 in 4% BSA versus 0.5% Brij 98 receiver solutions. The DSC studies showed that CP 55,940 had a significantly lower melting point, smaller heat of fusion, and corresponding higher calculated thermodynamic activity than the more crystalline WIN 55,212-2 Mesylate salt. The permeation results indicated that WIN 55,212-2 Mesylate, CP 55,940, and other potent synthetic cannabinoids with these physicochemical properties could be ideal candidates for the development of a transdermal therapeutic system.
Influence of WIN 55,212-2 on the anticonvulsant and acute neurotoxic potential of clobazam and lacosamide in the maximal electroshock-induced seizure model and chimney test in mice
Epilepsy Res 2014 Dec;108(10):1728-33.PMID:25458536DOI:10.1016/j.eplepsyres.2014.10.004.
The influence of WIN 55,212-2 Mesylate (WIN) on the anticonvulsant activity and acute neurotoxic potential of clobazam (CLB) and lacosamide (LCM) was studied in the maximal electroshock-induced seizure (MES) model and chimney test in mice. Results: indicate that WIN administered intraperitoneally, at doses of 2.5 and 5 mg/kg significantly enhanced the anticonvulsant action of CLB in the MES test by reducing its median effective dose (ED50) from 20.80 mg/kg to 12.05 mg/kg (P<0.05), and 8.22 mg/kg (P<0.001), respectively. In contrast, WIN (1.25 mg/kg) did not significantly potentiate the anticonvulsant activity of CLB against MES-induced seizures. Similarly, WIN at doses of 1.25, 2.5 and 5 mg/kg had no significant impact on the anticonvulsant action of LCM in the MES test. On the other hand, WIN (5 mg/kg) had no impact on the acute neurotoxic effects of CLB and LCM in the chimney test and the median toxic doses (TD50) for CLB and LCM were almost unchanged. Thus, WIN (5 mg/kg) elevated the protective index values for CLB (from 1.41 to 3.07) and LCM (from 3.60 to 4.91). In conclusion, WIN potentiates suppression of tonic-clonic seizures produced by CLB in the mouse MES model, without affecting acute neurotoxic adverse effects of CLB in the chimney test in mice, which is favorable from a preclinical point of view.
Permeation of WIN 55,212-2, a potent cannabinoid receptor agonist, across human tracheo-bronchial tissue in vitro and rat nasal epithelium in vivo
J Pharm Pharmacol 2006 Nov;58(11):1459-65.PMID:17132208DOI:10.1211/jpp.58.11.0006.
The aim of this study was to investigate the intranasal absorption of R-(+)-WIN 55,212-2 mesylate in vivo and in vitro. Permeation experiments of R-(+)-WIN 55,212-2 formulations with 2% dimethyl-beta-cyclodextrin (DMbetaCD), 2% trimethyl-beta-cyclodextrin (TMbetaCD) or 2% randomly methylated-beta-cyclodextrin (RAMbetaCD) in 1:1 propylene glycol/saline and 1.5% propylene glycol +3% Tween 80 in saline were conducted using EpiAirway tissue and an anesthetized rat nasal absorption model, respectively. Samples were analysed by liquid chromatography-mass spectrometry. Mucosal tolerance was screened using paracellular marker permeation and tissue viability as indices. Nasal absorption of WIN 55,212-2 was rapid, with a t(max) (time of peak concentration) of 0.17 to 0.35 h in vivo. Relative to 1.5% propylene glycol +3% Tween 80 (control), 1:1 propylene glycol/saline, RAMbetaCD, DMbetaCD and TMbetaCD resulted in 24-, 20-, 17- and 10-fold WIN 55,212-2 permeation increases in vitro, respectively. The in vivo absolute bioavailabilities were also increased with 1:1 propylene glycol/saline, RAMbetaCD, DMbetaCD and TMbetaCD compared to 1.5% propylene glycol +3% Tween 80 (0.15 vs. 0.66-0.77). The viability of the EpiAirway tissues was significantly reduced by DMbetaCD and TMbetaCD formulations. This study showed that WIN 55,212-2 Mesylate can be delivered via the nasal route. Absorption of R-(+)-WIN 55,212-2 was rapid and bioavailability was significantly improved using methylated cyclodextrins and propylene glycol-based cosolvent.
Effects of WIN 55,212-2 Mesylate on the anticonvulsant action of lamotrigine, oxcarbazepine, pregabalin and topiramate against maximal electroshock-induced seizures in mice
Eur J Pharmacol 2013 Nov 15;720(1-3):247-54.PMID:24161913DOI:10.1016/j.ejphar.2013.10.020.
The aim of this study was to determine the effect of WIN 55,212-2 Mesylate (WIN - a non-selective cannabinoid CB1 and CB2 receptor agonist) on the protective action of four second-generation antiepileptic drugs (lamotrigine, oxcarbazepine, pregabalin and topiramate) in the mouse maximal electroshock seizure model. Tonic hind limb extension (seizure activity) was evoked in adult male albino Swiss mice by a current (sine-wave, 25 mA, 500 V, 50 Hz, 0.2s stimulus duration) delivered via auricular electrodes. Drug-related adverse effects were ascertained by use of the chimney test (evaluating motor performance), the step-through passive avoidance task (assessing long-term memory) and the grip-strength test (evaluating skeletal muscular strength). Total brain concentrations of antiepileptic drugs were measured by high-pressure liquid chromatography to ascertain any pharmacokinetic contribution to the observed antiseizure effect. Results indicate that WIN (5mg/kg, i.p.) significantly enhanced the anticonvulsant action of lamotrigine (P<0.05), pregabalin (P<0.001) and topiramate (P<0.05), but not that of oxcarbazepine in the maximal electroshock-induced tonic seizure test in mice. Furthermore, none of the investigated combinations of WIN with antiepileptic drugs were associated with any concurrent adverse effects with regards to motor performance, long-term memory or muscular strength. Pharmacokinetic characterization revealed that WIN had no impact on total brain concentrations of lamotrigine, oxcarbazepine, pregabalin and topiramate in mice. These preclinical data would suggest that WIN in combination with lamotrigine, pregabalin and topiramate is associated with beneficial anticonvulsant pharmacodynamic interactions in the maximal electroshock-induced tonic seizure test.
Effects of WIN 55,212-2 (a synthetic cannabinoid CB1 and CB2 receptor agonist) on the anticonvulsant activity of various novel antiepileptic drugs against 6 Hz-induced psychomotor seizures in mice
Pharmacol Biochem Behav 2015 Mar;130:53-8.PMID:25592741DOI:10.1016/j.pbb.2015.01.003.
The purpose of this study was to determine the influence of WIN 55,212-2 Mesylate (WIN-a non-selective cannabinoid CB1 and CB2 receptor agonist) on the anticonvulsant activity of various second- and third-generation antiepileptic drugs (i.e., gabapentin, lacosamide, levetiracetam, oxcarbazepine, pregabalin and tiagabine) in the mouse 6 Hz-induced psychomotor seizure model. Psychomotor seizures were evoked in albino Swiss mice by a current (32 mA, 6 Hz, 3s stimulus duration) delivered via ocular electrodes. Additionally, total brain antiepileptic drug concentrations were measured. Results indicate that WIN (5 mg/kg, administered i.p.) significantly potentiated the anticonvulsant action of gabapentin (P < 0.05) and levetiracetam (P < 0.01), but not that of lacosamide, oxcarbazepine, pregabalin or tiagabine in the mouse psychomotor seizure model. Moreover, WIN (2.5 mg/kg) had no significant effect on the anticonvulsant activity of all tested antiepileptic drugs in the 6 Hz test in mice. Measurement of total brain antiepileptic drug concentrations revealed that WIN (5 mg/kg) had no impact on gabapentin or levetiracetam total brain concentrations, indicating the pharmacodynamic nature of interaction between these antiepileptic drugs in the mouse 6Hz model. In conclusion, WIN in combination with gabapentin and levetiracetam exerts beneficial anticonvulsant pharmacodynamic interactions in the mouse psychomotor seizure model.
