Mechanisms underlying vasorelaxation induced in rat aorta by galetin 3,6-dimethyl ether, a flavonoid from Piptadenia stipulacea (Benth.) Ducke.
In this study, we investigated the relaxant action of galetin 3,6-dimethyl ether (FGAL) on rat aorta. The flavonoid relaxed both PMA‑ and phenylephrine (Phe)-induced contractions (pD2 = 5.36 ± 0.11 and 4.17 ± 0.10, respectively), suggesting the involvement of PKC and Phe pathways or α1 adrenergic receptor blockade. FGAL inhibited and rightward shifted Phe-induced cumulative contraction‑response...
متن کاملMechanisms underlying the relaxant effect of Galetin 3,6- dimethyl ether, from Piptadenia stipulacea (Benth.) Ducke, on guinea-pig trachea.
Galetin 3,6-dimethyl ether (FGAL), a flavonoid from the aerial parts of Piptadenia stipulacea (Benth.) Ducke, was found to exert a relaxant effect on carbachol (CCh)-pre-contracted guinea-pig trachea. Based on cumulative concentration-response curves to CCh, FGAL antagonized muscarinic receptors pseudo-irreversibly and noncompetitively, since it inhibited and shifted these curves towards higher...
متن کاملPhysiological Quality of Soybean Seeds Affected by Water and Light Deficits
In order to determine the best developmental stage of soybean at which maximum seed quality is attained under different shadings (S1, S2, S3: 0, 35 and 75% shade, respectively) and irrigation treatments (I1, I2, I3, I4: irrigation after 60, 90, 120 and 150 mm evaporation from class A pan, respectively), two split plot experiments using randomized complete block design with three replications we...
متن کاملMinerals and nutritional composition of radhuni (Carum roxburghianum Benth.) seeds
Radhuni (Carum roxburghianum Benth.) seeds of three indigenous cultivars grown in Bangladesh have been studied for minerals and various compositional properties as well as assess their role in human nutrition. Variability was observed among investigated cultivars in terms of physical characteristics (e.g. seed volume, seed density, hydration capacity, hydration index, swelling capacity and swel...
