The present study investigated the vascular effects of 5,7‐dimethoxyflavone (DMF), isolated from the rhizomes of Kaempferia parviflora (KP), on rat isolated aortic rings and its possible mechanisms. DMF (1–100 μm) caused concentration‐dependent relaxations in aortic rings precontracted with methoxamine. This effect was significantly reduced by removal of the endothelium, and after pretreatment with NG‐nitro‐L‐arginine methyl ester (L‐NAME, 300 μm), indomethacin (10 μm) and 1H‐[1,2,4]oxadiazolo… 
Vasorelaxant effects of 3 , 5 , 7 , 3 ' , 4 '-pentamethoxyflavone isolated from Kaempferia parviflora : partly stimulating the release of NO and H 2 S by rat thoracic aorta
Results revealed that PMF caused a relaxation of thoracic aortic rings by stimulating the release of nitric oxide and H2S, that act as an adenylyl cyclase stimulator, and an inhibitor of intracellular calcium mobilization.
Vasodilatory Effect of Wogonin on the Rat Aorta and Its Mechanism Study.
Findings suggest that wogonin-induced responses are mainly due to the inhibition of both intracellular Ca(2+) release and extracellular Ca (2+) influx.
Effects of Phikud Navakot extract on vascular reactivity in the isolated rat aorta.
It is suggested that NVKE decreased vasorelaxation to carbachol in the rat aorta, which may exert at least against muscarinic receptors, which support the use of Phikud Navakot, a major ingredient of Yahom Navakots against dizziness and fainting.
Effects of Kaempferia parviflora Wall. Ex. Baker and Sildenafil Citrate on cGMP Level, Cardiac Function, and Intracellular Ca2+ Regulation in Rat Hearts
KPE has positive effect on NO signaling in the heart, resulting in an increased cGMP level, similar to that of sildenafil citrate, which was found to influence the physiology of normal heart via the attenuation of cardiac function and the reduction of Ca2+ transient in ventricular myocytes.
Vasodilator Activity of Compounds Isolated from Plants Used in Mexican Traditional Medicine
Arterial hypertension is one of the main risk factors in the development of cardiovascular diseases. Therefore, it is important to look for new drugs to treat hypertension. In this study, we carried
A 5,7-Dimethoxyflavone/Hydroxypropyl-β-Cyclodextrin Inclusion Complex with Anti-Butyrylcholinesterase Activity
The water solubility of 5,7-DMF was increased 361.8-fold by complexation with HPβ-CD and overcame the precipitation problem observed in aqueous buffers, such as during in vitro anti-butyrylcholinesterase activity assays.
Relaxant effects of lippia microphylla cham. (Verbenaceae) on isolated rat aorta and trachea
The aerial parts of Lippia microphylla have smooth muscle relaxant properties supporting its use in folk medicine against respiratory disease and the extract induced relaxation of both organs contracted by KCl is indicative of Ca influx blockade.
Pharmacokinetics, Bioavailability, Tissue Distribution, Excretion, and Metabolite Identification of Methoxyflavones in Kaempferia parviflora Extract in Rats
The present study was designed to characterize the pharmacokinetics of KP extract, including bioavailability, distribution, excretion, and identification of metabolites after administration of a KP ethanolic extract to provide the information on blood and tissue levels.


Mechanisms of Kaempferia parviflora extract (KPE)- induced vasorelaxation in the rat aorta
KPE had a vasodilator effect in the rat isolated aortic rings and support the traditional use of KPE as an antihypertensive agent.
Anticholinesterase activity of 7‐methoxyflavones isolated from Kaempferia parviflora
Interestingly, 5,7‐dimethoxyflavone (7) exhibited strong selectivity for BChE over AChE which may be of great interest to modify as a treatment agent for Alzheimer's disease.
