Structural highlights
DiseaseBMP1_HUMAN Defects in BMP1 are the cause of osteogenesis imperfecta 13 (OI13) [MIM:614856. An autosomal recessive form of osteogenesis imperfecta, a connective tissue disorder characterized by bone fragility, low bone mass, and recurrent fractures. OI13 is characterized by normal teeth, faint blue sclerae, severe growth deficiency, borderline osteoporosis, severe bone deformity, and recurrent fractures affecting both upper and lower limbs.[1] [2] FunctionBMP1_HUMAN Cleaves the C-terminal propeptides of procollagen I, II and III. Induces cartilage and bone formation. May participate in dorsoventral patterning during early development by cleaving chordin (CHRD). Responsible for the proteolytic activation of lysyl oxidase LOX. Publication Abstract from PubMedBone Morphogenetic Protein 1 (BMP1) inhibition is a potential method for treating fibrosis because BMP1, a member of the zinc metalloprotease family, is required to convert pro-collagen to collagen. A novel class of reverse hydroxamate BMP1 inhibitors was discovered, and cocrystal structures with BMP1 were obtained. The observed binding mode is unique in that the small molecule occupies the nonprime side of the metalloprotease pocket providing an opportunity to build in metalloprotease selectivity. Structure-guided modification of the initial hit led to the identification of an oral in vivo tool compound with selectivity over other metalloproteases. Due to irreversible inhibition of cytochrome P450 3A4 for this chemical class, the risk of potential drug-drug interactions was managed by optimizing the series for subcutaneous injection.
