Pancreatic stellate cells . The cells in the lower frame are under the action of WIN 55,212-2. They are thought to assume a more "quiescent " phenotype. From Michalski et al., 2008.[ 2]
WIN 55,212-2 is a chemical described as an aminoalkylindole derivative, which produces effects similar to those of cannabinoids such as tetrahydrocannabinol (THC) but has an entirely different chemical structure .[ 3] [ 4] [ 5]
WIN 55,212-2 is a potent cannabinoid receptor agonist [ 6] that has been found to be a potent analgesic[ 7] in a rat model of neuropathic pain.[ 8] It activates p42 and p44 MAP kinase via receptor-mediated signaling.[ 9]
At 5 μM WIN 55,212-2 inhibits ATP production in sperm in a CB1 receptor -dependent fashion.[ 10]
WIN 55,212-2, along with HU-210 and JWH-133, may prevent the inflammation caused by amyloid beta proteins involved in Alzheimer's disease , in addition to preventing cognitive impairment and loss of neuronal markers . This anti-inflammatory action is induced through agonist action at cannabinoid receptors , which prevents microglial activation that elicits the inflammation.
WIN 55,212-2 is a full agonist at the CB1 cannabinoid receptor (K i = 1.9 nM) and has much higher affinity than THC (K i = 41 nM) for this receptor.[ 11] WIN 55,212-2 is also an agonist of the PPARα and PPARγ nuclear receptors.[ 12]
WIN 55,212-2 reduces voluntary wheel running in laboratory mice, but with effects that depend on both genetic background and sex.[ 13]
In the United States, all CB1 receptor agonists of the 3-(1-naphthoyl)indole class such as WIN 55,212-2 are Schedule I Controlled Substances .[ 14] WIN 55,212-2 is illegal in the UK.[ 15]
WIN 55,212-2 is also a CB2 receptor agonist and thereby, like other cannabinoid CB2 agonists, found to significantly improve cardiac recovery after ischaemia /reperfusion (I/R) in the hearts of diabetic fatty rats, by restoring coronary perfusion pressure and heart rate to pre-ischaemic levels, by the restoration of the inducible nitric oxide synthase (iNOS)/endothelial nitric oxide synthase (eNOS) cardiac equilibrium .[ 16] [ 17]
