Effects of curcumin, a biologically active ingredient of turmeric, were tested on the Ca2+transients induced by the activation of α7 subunit of the human nicotinic acetylcholine (α7nACh) receptor expressed in SH-EP1 cells. Curcumin caused a significant potentiation of choline (1 mM)-induced Ca2+ transients with an EC50 value of 133 nM. The potentiating effect of curcumin was not observed in Ca2+ transients induced by high K+ (60 mM) containing solutions or activation of α4β2 nACh receptors and the extent of curcumin potentiation was not altered in the presence of …

Cannabidiol (CBD), a major nonpsychotropic cannabinoid found in Cannabis plant, has been shown to influence cardiovascular functions under various physiological and pathological conditions. In the present study, the effects of CBD on contractility and electrophysiological properties of rat ventricular myocytes were investigated. Video edge detection was used to measure myocyte shortening. Intracellular Ca2+ was measured in cells loaded with the Ca2+ sensitive fluorescent indicator fura-2 AM. Whole-cell patch clamp was used to measure action potential and Ca2+ currents. Radioligand binding was employed to study pharmacological characteristics of CBD binding. CBD (1 μM) caused a significant decrease in the amplitudes of …
