Fibrodysplasia ossificans progressiva (FOP) and diffuse intrinsic pontine glioma (DIPG) are diseases that typically manifest in childhood and are associated with severely reduced life expectancy. However, there are currently no effective therapies for these diseases, which remain incurable. Activin receptor-like kinase-2 (ALK2), encoded by the ACVR1 gene, is a bone morphogenetic protein (BMP) type-I receptor subtype that plays an important physiological role in the development of bones, muscles, brain, and other organs. Constitutively active mutants of ALK2 have been identified as causative of FOP and involved in the tumorigenesis of DIPG owing to abnormal activation of BMP signaling, and therefore have emerged as promising treatment targets. Here, we describe these two diseases, along with the link to ALK2 signal transduction, and highlight potential ALK2 inhibitors that are under development to offer new hope for patients with FOP and DIPG.

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.
