2-AMINO-5-BROMO-4-HYDROXY-6-PHENYLPYRIMIDINE Usage And Synthesis

Description

Bropirimine is an immunomodulator with diverse biological activities. It is a toll-like receptor 7 (TLR7) agonist that inhibits RANKL-induced osteoclast differentiation of murine bone marrow-derived macrophages (BMDMs) in a concentration-dependent manner, an effect that is reversed by an anti-IFN-β antibody. Dietary administration of bropirimine (200 mg/kg twice per week) prevents development of transitional cell carcinomas (TCCs) in a mouse model of carcinogen-induced bladder carcinoma. Bropirimine (100 mg/kg) reduces pulmonary collagen accumulation and bronchoalveolar lavage fluid (BALF) monocyte and eosinophil infiltration in a hamster model of bleomycin-induced lung fibrosis. It also delays disease onset and progression and increases plasma IFN levels in a mouse model of experimental autoimmune encephalomyelitis (EAE).

Uses

Bropirimine is an orally active immunostimulant; anticancer agent. Bropirimine is an interferon inducer that is a potentially useful in the the treatment of superficial bladder cancer (transitional cell carcinoma). Studies suggest that Bropirimine has direct antitumor activity rather than a cytokine-mediated antitumor effect.

Uses

Bropirimine, an immunostimulating agent and toll like receptor (TLR7) agonist, is used in comparison with other TLR7 agonists such as imiquimod, R-848, loxoribine in interferon cell signaling research. Bropirimine may be used in experimental autoimmune encephalomyelitis (EAE) and bladder cancer research.

Definition

ChEBI: Bropirimine is a member of pyrimidines.

Biochem/physiol Actions

Bropirimine is an immunostimulating agent. The compound induces production of α and β interferons and enhances NK cell function. Bropirimine has antiproliferative effects in cancer cell lines and tumor growth in in vivo models.

storage

Desiccate at RT

Toxics Screening Level

The initial threshold screening level (ITSL) for bropirimine is 15 μg/m3 based on an annual averaging time.
