N-[ 4 - (1H-pyrazolo [3,4-b] pyrazin-6-yl)-phenyl]-sulfamide and their use as medicaments

The invention relates to N-[4-(1H-pyrazolo[3,4-b] pyrazine-6-yl)-phenyl]-sulfonamides of a formula I. In the formula I, Ar, R1, R2 and n have meanings as shown in the claims. The compounds of the formula I are compounds which are valuable, have pharmacological activity and can adjust the activity of protein kinase, particularly the activity of serum and glucocorticoid induced kinase (SGK), and more particularly the activity of serum and glucocorticoid induced kinase isoform (SGK-1, SGK1). The compounds are suitable for treating diseases with inappropriate activity of the SGK, such as degenerative joint diseases or inflammatory process such as osteoarthritis or rheumatism. The invention also relates to a method for preparing the compounds of the formula I, an application of the compounds serving as the medicines and medicine compositions containing the compounds.

Discovery of N-[4-(1H-pyrazolo[3,4-b]pyrazin-6-yl)-phenyl]-sulfonamides as highly active and selective SGK1 inhibitors

From a virtual screening starting point, inhibitors of the serum and glucocorticoid regulated kinase 1 were developed through a combination of classical medicinal chemistry and library approaches. This resulted in highly active small molecules with nanomolar activity and a good overall in vitro and ADME profile. Furthermore, the compounds exhibited unusually high kinase and off-target selectivity due to their rigid structure. (Chemical Presented).

N-[ 4-(1H-pypazolo [3, 4-b] aminopyrazine-6-yl)-phenyl]-and its use as a chemical acylsulfonamide

PROBLEM TO BE SOLVED: To provide a compound effective for the treatment of diseases due to the inadequacy of serum and glucocorticoid adjustment kinase (SGK) activities, for instance, degenerative arthropathy or inflammatory process, e.g., osteoarthritis or rheumatism, to provide its use as a drug, and to provide a pharmaceutical composition containing the same. SOLUTION: The compound is represented by formula I ( wherein, Ar is selected from the group consisting of phenyl and five- or six-membered monocyclic aromatic heterocyclic rings each containing a ring heteroatom selected from the group consisting of nitrogen, oxygen and sulfur; R1 is H, amino or the like; R2 is a halogen atom, alkyl or the like; and n is 0, 1 or 2).
