The In Vivo Effects of the CB1-Positive Allosteric Modulator GAT229 on Intraocular Pressure in Ocular Normotensive and Hypertensive Mice.

PURPOSE: Orthosteric cannabinoid receptor 1 (CB1) activation leads to decreases in intraocular pressure (IOP). However, use of orthosteric CB1 agonists chronically has several disadvantages, limiting their usefulness as clinically relevant drugs.…

Neuroprotection by (endo)Cannabinoids in Glaucoma and Retinal Neurodegenerative Diseases.

BACKGROUND: Emerging neuroprotective strategies are being explored to preserve the retina from degeneration, that occurs in eye pathologies like glaucoma, diabetic retinopathy, age-related macular degeneration, and retinitis pigmentosa. Incidentally, neuroprotection…

Controlled-Deactivation CB1 Receptor Ligands as a Novel Strategy to Lower Intraocular Pressure

Abstract : Nearly half a century has passed since the demonstration that cannabis and its chief psychoactive component Δ9-THC lowers intraocular pressure (IOP). Elevated IOP remains the chief hallmark and therapeutic…

Cannabinoids in glaucoma II: The effect of different cannabinoids on intraocular pressure of the rabbit

Thirty-two different cannabinoids were tested for their ability to reduce intraocular pressure (IOP) in the rabbit. These included many of Δ9-and Δ8 -THC derivatives and metabolites along with other natural and…

Cannabinoids for gastrointestinal diseases: potential therapeutic applications

Δ9-Tetrahydrocannabinol (the active ingredient of marijuana), as well as endogenous and synthetic cannabinoids, exert many biological functions by activating two types of cannabinoid receptors, CB1 and CB2 receptors. CB1 receptors have been detected…

Cannabidiol reduces airway inflammation and fibrosis in experimental allergic asthma

Asthma is characterized by chronic lung inflammation and airway hyperresponsiveness. Asthma remains a major public health problem and, at present, there are no effective interventions capable of reversing airway remodelling. Cannabidiol (CBD) is known to exert…
