Abstract

Chlorothiazide (6-chloro-2H-1,2,4-benzothiadiazine-7-sulfonamide 1,1-dioxide) is diuretic drug normally used within a hospital setting to manage excess fluid associated with congestive heart failure and as an antihypertensive drug. The goal of this experiment was to define the effects of Chlorothiazide on muscarinic receptors. We determined the effects of Chlorothiazide on calcium signaling by using ratiometric fluorescent dye on Chinese hamster ovary (CHO) cells, which have the human M3 muscarinic receptors, and imaging the amounts of intracellular calcium concentrations released. Based on the results of the experiment conducted, Chlorothiazide has no legitimate inhibitory effect on store operated calcium entry (SOCE) that was induced by activation of the M3 receptors. Chlorothiazide most likely acts as a stimulant to the uptake of calcium.
