Popis: | Flavonoids have shown beneficial effects in various disease conditions as reported by various previous studies. Biochanin-A is a flavonoid present in various plants in nature. Present investigation was done to assess the vasorelaxant potential of biochanin-A on isolated coronary artery of goat and its possible mechanism of action. Vascular reactivity experiments were done on circumflex coronary artery of goats using the tension experiments. Goat coronary arterial rings were relaxed with biochanin-A in concentration (0.1–100 μM)-dependent manner. Endothelium had no effect on biochanin-A-induced relaxation. Maximum relaxation induced by biochanin-A was 116.54 ± 12.21% in endothelium-intact artery and it was not significantly different with maximal relaxation (108.22 ± 1.88%) of endothelium-denuded vessel. L-NAME (100 μM) did not show any effect on biochanin-A-induced relaxation. TEA (BKCa channel blocker), and BaCl2 (KIR blocker) had no effect on biochanin-A-induced relaxation. However, biochanin-A-induced maximal relaxation (71.72 ± 4.50%) was reduced significantly (P |
