Definitions
- the present invention relates to 2-aminothiadiazole derivatives, to processes for their preparation and to pharmaceutical compositions containing them.
- These compounds are potent agonists of S1P1 receptors and thus, they are useful in the treatment, prevention or suppression of diseases and disorders known to be susceptible to improvement by sphingosine-1 -phosphate receptors agonists (S1 P1), such as autoimmune diseases, chronic immune and inflammatory diseases, transplant rejection, malignant neoplastic diseases, angiogenic-related disorders, pain, neurological diseases, viral and infectious diseases.
- S1 P1 sphingosine-1 -phosphate receptors agonists
- Sphingosine -1 phosphate is a pleiotropic lipid mediator that exhibits a broad spectrum of biological activities, including cell proliferation, survival, lymphocyte trafficking, cytoskeletal organization, and morphogenesis.
- S1P is generated from endogenous sphingosine through phosphorylation by specific kinases, named sphingosine kinases 1 and 2.
- the levels of S1 P in biological fluids and tissues are tightly regulated by the balance between its synthesis by sphingosine kinases and its degradation by S1 P lyase. This tight control is important since an excessive production of S1 P has been associated to various pathological conditions, such as angiogenesis and vascular permeability changes in cancer, inflammation, myocardial infarction or transplant rejection.
- S1 P1 to S1 P5 G-protein coupled receptor subtypes
- S1 P1 to S1 P5 G-protein coupled receptor subtypes
