which is an inhibitor of spleen tyrosine kinase (Syk) and therefore potentially of use in treating diseases resulting from inappropriate activation of mast cells, macrophages, and B-cells and related inflammatory responses and tissue damage, for instance inflammatory disease and/or allergic disorders, and in cancer therapy, specifically heme malignancies, and autoimmune conditions.
that led to the discovery of the clinical-staged Syk inhibitor sovleplenib (41) via a structure–activity relationship investigation and pharmacokinetics (PK) optimization of a pyrido[3,4-b]pyrazine scaffold. Sovleplenib is a potent and selective Syk inhibitor with favorablepreclinical PK profiles and robust anti-inflammation efficacy in a preclinical collagen-induced arthritis model. Sovleplenib is now
