Definitions
- the present application relates to new pyrimidinone derivatives. These products have good affinity for certain cannabinoid receptor subtypes, particularly CB2 receptors. They are particularly useful for treating disease states and diseases in which one or more cannabinoid receptors are involved.
- the invention also relates to pharmaceutical compositions containing said products and their use for the preparation of a medicament.
- Cannabinoids are psychoactive components found in Indian cannabis (Cannabis sativa) including nearly 6 different molecules, the most represented being delta-9-tetrahydrocannabinol.
- Indian cannabis Crobis sativa
- the knowledge of the therapeutic activity of cannabis goes back to the ancient Chinese dynasties in which, 5,000 years ago, cannabis was used for the treatment of asthma, migraines and gynecological disorders. It was in 1850 that cannabis extracts were recognized and included in the American pharmacopoeia.
- Cannabinoids are known to have different effects on many functions and organs, the most important being the central nervous system and the cardiovascular system. These effects include impaired memory, euphoria, and sedation. Cannabinoids also increase the pulse rate and change the systemic blood pressure. Peripheral effects related to bronchial constriction, immunomodulation and inflammation were also observed. More recently, cannabinoids have been shown to suppress cellular and humoral immune responses and have anti-inflammatory properties. Despite all these properties, the therapeutic use of cannabinoids is controversial for its psychoactive effects (cause of dependence) but also for its multiple side effects not yet fully characterized.
- CB1 and CB2 Two cannabinoid receptors have been identified and cloned, CB1 and CB2.
- CB1 is expressed predominantly in the central nervous system while CB2 is expressed in peripheral tissues, mainly in the immune system.
- These 2 receptors are members of the family of G-protein coupled receptors and their inhibition is related to the activity of adenylate cyclase.
- CB2 modulators offer a unique approach to pharmacotherapy against immune disorders, inflammation, osteoporosis, renal ischemia and other disease states.
- cannabinoid analogs having a high affinity for the CB2 receptor.
- Cannabinoid analogs that specifically modulate the CB2 receptor directly or indirectly can produce clinically useful effects without affecting the central nervous system thereby providing a rational therapeutic approach for a wide variety of disease states.
- novel compounds of this invention modulate CB2 activity and are therefore useful for the treatment and prevention of disease states and diseases associated with cannabinoid receptor activity such as, but not limited to, proliferative disorders. such as cancer, immune disorders, inflammation, pain, osteoporosis, epilepsy, nausea associated with chemotherapy, fibrosis, gastrointestinal disorders, neurodegenerative diseases including multiple sclerosis and dyskinesia, Parkinson's disease, Huntington's chorea, Alzheimer's disease but also to prevent or cure diseases associated with motor function such as Tourette's syndrome, to provide neuroprotection.
