56741-95-8 structure
  • Name: Bropirimine
  • Chemical Name: 2-Amino-5-bromo-4-hydroxy-6-phenylpyrimidine
  • CAS Number: 56741-95-8
  • Molecular Formula: C10H8BrN3O
  • Molecular Weight: 266.094
  • Catalog: Signaling Pathways Immunology/Inflammation Toll-like Receptor (TLR)
  • Create Date: 2018-11-30 18:00:20

  • Bropirimine is a synthetic agonist for toll-like receptor 7 (TLR7). Bropirimine inhibits differentiation of osteoclast precursor cells into osteoclasts via TLR7-mediated production of IFN-β. Bropirimine is an orally active immunomodulator that has demonstrated anticancer activity in transitional cell carcinoma in situ (CIS) in both the bladder and upper urinary tract[1][2].
