| Hazard Information | Back Directory | [Uses]
3,5,7,3’,4’-Pentamethoxyflavone is a Ca2+ channel inhibitor. 3,5,7,3’,4’-Pentamethoxyflavone can protect DNA from oxidative damage. 3,5,7,3’,4’-Pentamethoxyflavone can induce relaxation of the human corpus cavernosum through calcium mobilization-related mechanisms. 3,5,7,3’,4’-Pentamethoxyflavone can promote the expression of eNOS and cystathionine gamma lyase CSE proteins in middle-aged male rats and regulate vascular function. 3,5,7,3’,4’-Pentamethoxyflavone can be used in research related to diabetes and cardiovascular diseases[1][2][4]. | [in vivo]
3,5,7,3’,4’-Pentamethoxyflavone (22 mg/kg; twice daily; 6 weeks; p.o.) can promote the expression of eNOS and CSE proteins in middle-aged male rats, and regulate vascular function by antagonizing the contraction of phenylephrine and enhancing the vasodilation of acetylcholine[4]. | Animal Model: | Middle-aged (12–14 month old) Wistar male rats[4]. | | Dosage: | 22 mg/kg | | Administration: | Oral gavage (p.o.); twice daily; 6 weeks | | Result: | Caused a decrease in plasma glucose and an increase in plasma HDL cholesterol levels of the rats. |
