Biological Activity for Doxazosin mesylate

Scientific Data

Cell Viability Reduced viability of differentiated cardiomyocytes exposed to cardiotoxic small molecules View Larger

Reduced viability of differentiated cardiomyocytes exposed to cardiotoxic small molecules. The viability of differentiated cardiomyocytes was assessed using a Resazurin metabolism assay. A) Untreated cells metabolize Resazurin (Catalog # AR002) to produce resorufin, a fluorescent molecule that can be measured using a fluorometric plate reader. Resorufin fluorescence accumulated in untreated cardiomyocytes. Cells treated with the cardiotoxic small molecules Staurosporine (blue; Catalog # 1285), a non-selective protein kinase inhibitor, or Doxazosin (tan; Catalog # 2964), an alpha 1 antagonist, did not metabolize Resazurin, as shown by lack of fluorescence accumulation, indicating a loss of viability upon treatment. B) Cell morphology of untreated, Staurosporine-treated, and Doxazosin-treated cardiomyocytes was assessed by brightfield microscopy.
