Application

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.

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.

The role of bropirimine in prostate cancer remains unexplored. To address the efficacy of this immune modulator as neoadjuvant therapy we utilized the orthotopic placement of the Dunning AT-3 tumor. 2.4-2.6 x 10(6) Dunning AT-3 cells were injected into the

Bropirimine (2-amino-5-bromo-6-phenyl-4-pyrimidinone) is a member of a class of antineoplastic agents known as aryl pyrimidinones. In human liver microsomal incubations, bropirimine oxidative metabolism is characterized by the formation of three metabolites. Mass spectrometric analysis of the incubation mixture revealed three

We showed previously that a 5-halo-6-phenyl-pyrimidinone, bropirimine (PNU-54461), inhibited progression of severe experimental autoimmune encephalomyelitis (EAE), an animal model of human multiple sclerosis. In the work presented here, we examined the activity of a group of chemically-related bropirimine analogues. First

A rapid and simple high-performance liquid chromatography (HPLC) method incorporating automated solid-phase extraction (SPE) is described for the determination of bropirimine, 2-amino-5-bromo-6-phenyl-4(3H)-pyrimidinone, in plasma samples from various species. Using an automated sample processor, plasma samples were loaded onto C18 SPE
