Darifenacin hydrobromide is a selective and orally active M3 muscarinic receptor (M3R) antagonist. It is used in the study of urinary incontinence and other symptoms of overactive bladder, and has demonstrated anti-tumor effects by inhibiting tumor growth in colorectal cancer cells. In vitro, it inhibits Kv currents and the phosphorylation of p38, ERK1/2, and Akt. In vivo studies showed antitumor effects in xenograft mouse models and decreased afferent activity in rat bladders.
