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.

Paclitaxel, bropirimine and linomide therapy was evaluated in a murine prostate cancer model. All drugs were effective in impeding tumor growth but the mechanisms of action varied. Paclitaxel inhibited bcl-2 expression suggesting an apoptotic mechanism. Bropirimine, while inhibiting bcl-2 expression

Radiotherapy can convert malignant cells into an in situ anticancer vaccine, but is often inadequate at generating sufficient pro-inflammatory signals to optimally activate innate and adaptive immune responses. Topical imiquimod is a powerful pro-inflammatory agent with clinical activity against superficial
