Definitions
- TITLE Inhibitors of the interaction between ROCK and PDK1 protein kinases
- the present invention relates to inhibitors of the interaction between ROCK and PDK1 protein kinases and their uses as anti-inflammatory and anti-interferon agents.
- the present invention also relates to a pharmaceutical composition comprising an inhibitor of the interaction between ROCK and PDK1 protein kinases and its use in the prevention and/or treatment of inflammatory diseases, viral and/or bacterial infections and autoimmune diseases. .
- Inflammation is a beneficial physiological process for the body insofar as it is transient. For example, it helps fight bacterial or viral infections. Nevertheless, many pathologies affecting several organs such as the intestine, the central nervous system, the osteo-articular system, the skin, the lungs, etc. are associated with chronic tissue inflammation. Chronic inflammation alters tissue homeostasis, leading to functional abnormalities such as digestive disorders, amplification of neurological or neurodegenerative diseases, motor disability, skin lesions, respiratory failure... Chronic inflammation damage results from the continuous production of inflammatory cytokines (TNFa, interleukins, interferons) by immune cells or related cells (microglia cells in the central nervous system) which leads to the deterioration of cells sensitive to inflammatory factors. Very few drugs (steroidal and non-steroidal) currently make it possible to contain the inflammatory response (aspirin, ibuprofen, paracetamol, corticosteroids), some of which generate significant side effects in humans.
