Quercetin and ferulic acid are two phytochemicals extensively represented in the plant kingdom daily consumed considerable amounts through diets. Due to a common phenolic structure, these molecules share several pharmacological properties, e.g., antioxidant free radical scavenging, anti-cancer, anti-inflammatory, anti-arrhythmic, vasorelaxant. The aim of present work was combination single chem...
BACKGROUND Prunus yedoensis Matsum. is used as traditional medicine-'Yaeng-Pi' or 'Hua-Pi'-in Japan and Korea. However, no studies have examined the pharmacological activities of the P. yedoensis bark. Only the antioxidant and antiviral activities of P. yedoensis fruit and the anti-hyperglycaemic effect of P. yedoensis leaf have been investigated. While studying the antihypertensive effects of ...
atp-sensitive potassium (katp) channel openers have a relaxation effect due to the lower cellular membrane potential and inhibit calcium influx. there has been considerable interest in exploring katp channel openers in the treatment of various diseases such as cardiovascular, cerebrovascular, and urinary system disease and premature labor. the purpose of this study was to synthesize 3,3,6,6-tet...
OBJECTIVES The aim of this paper is to investigate the activities of Malaysian local herbs (Clinacanthus nutans Lindau, Strobilanthes crispus, Murdannia bracteata, Elephantopus scaber Linn., Pereskia bleo, Pereskia grandifolia Haw., Vernonia amygdalina, and Swietenia macrophylla King) for anti-hypertensive and vasorelaxant activity. An infrared (IR) macro-fingerprinting technique consisting of ...
INTRODUCTION Perivascular adipose tissue (PVAT) surrounds most vessels in the human body. Healthy PVAT has a vasorelaxant effect which is not observed in obesity. We assessed the contribution of nitric oxide (NO), inflammation and endothelium to obesity-induced PVAT damage. METHODS Rats were fed a high-fat diet or normal chow. PVAT function was assessed using wire myography. Skeletonised and ...
Intraperitoneal injection of all-trans-retinoic acid (ATRA) results in a reduction of blood pressure in spontaneously hypertensive rats. However, the mechanisms involved in this effect are not clear. We hypothesized that ATRA may relax resistance arteries. In this study, we found that ATRA relaxed phenylephrine-preconstricted mesenteric arterial rings, which were abrogated by the removal of the...
Objective—Although C-reactive protein (CRP) is increasingly recognized as an independent risk factor for acute myocardial events, recent evidence suggests that it can directly induce vasorelaxation. This study aimed to investigate the mechanism of this CRP-induced response. Methods and Results—Isometric tension recordings were used to measure endothelium-dependent and endotheliumindependent vas...

In this study, the possible involvement of L-type voltage-operated calcium channels in the vasorelaxant effect of the flavonoid quercetin was investigated, using the isolated aortic rings from normal male rats. Addition of quercetin (0.1 µM-1 mM) caused a significant dose-dependent relaxation of noradrenaline (NA)- and KCl-preconstricted rings and nifedipine attenuated this response, especially...
