Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: Remibrutinib (LOU064) is one of the examples claimed in Novartis' patent WO2015079417A1 [2], for novel amino pyrimidine derivatives that act as Bruton's tyrosine kinase (BTK) inhibitors and which claims their potential to treat autoimmune disorders, inflammatory/allergic diseases, transplant rejection and cancers of hematopoietic origin or solid tumours. The formal chemical name (LOU064; remibrutinib) to structure disclosure was published in February 2020 [1]. LOU064 is a covalent BTK inhibitor that binds the inactive conformation of the enzyme. This improves its selectivity compared to currently marketed covalent BTK inhibitors, and renders it more suitable for use in non-oncology indications.
