Other Forms of Darifenacin:

    Darifenacin purchased from MCE. Usage Cited in: Oncotarget. 2016 Apr 5;7(14):18085-94.  [Abstract]

    MACC1 is up-regulated by ACh through p-AMPK. A. ACh stimulates AMPK phosphorylation via M3R. B. Inhibition of AMPK activity by Dorsomorphin (8 μM) suppresses the induction of MACC1 expression by ACh. p-AMPK levels increase after ACh stimulation, and pretreatment of Darifenacin attenuates the ACh-induced increase of p-AMPK.

    生物活性

    Darifenacin (UK-88525) is a selective and orally active M3 muscarinic receptor (M3R) antagonist with a pKi of 8.9. Darifenacin binds >20-fold more specifically to M3R than to other muscarinic receptors. Darifenacin can be used in the study of urinary incontinence and other symptoms of overactive bladder. Darifenacin inhibits tumor growth in colorectal cancer cells and has anti-tumor effects[1][2][3][4][5][6].

    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
