Mutant activin receptor-like kinase-2 (ALK2) was reported to be closely associated with the pathogenesis of fibrodysplasia ossificans progressiva (FOP) and diffuse intrinsic pontine glioma (DIPG), and therefore presents an attractive target for therapeutic intervention. Through in silico virtual screenings and structure–activity relationship studies assisted by X-ray crystallographic analyses, a novel series of bis-heteroaryl pyrazole was identified as potent inhibitors of ALK2 (R206H). Derived from in silico hit compound RK-59638 (6a), compound 18p was identified as a potent inhibitor of ALK2 (R206H) with good aqueous solubility, liver microsomal stability, and oral bioavailability.
The present invention relates to novel and excellent small-molecule-corn pounds that specifically antagonize BMP signal pathways, and these compounds can be used to modulate cell growth, differentiation, proliferation, and apoptosis, and thus can be used to treat diseases or pathological symptoms related to BMP signal pathway including inflammation, cardiovascular diseases, hematopoietic diseases, cancer, osteodystrophia, or the like, particularly, fibrodysplasia ossificans progressiva, and the present invention relates to provision of a pharmaceutical and pharmacological agent used for specifically antagonizing the BMP signal pathways and acting on the BMP signal pathways in the prevention and treatment or experimental application since the compounds can be beneficial for regulating cell differentiation and/or cell proliferation.
