7,4'-二羟基黄酮 TN1273

Product Introduction
Bioactivity


英文名: 7,4'-Dihydroxyflavone

描述: 7,4'-Dihydroxyflavone (4',7-Dihydroxyflavone) 是从甘草中分离的类黄酮，是 eotaxin/CCL11抑制剂，抑制嗜酸性粒细胞趋化因子产生。它通过调节 NF-κB、STAT6 和 HDAC2，抑制 MUC5A 基因表达和粘液产生。

体外活性: Root exudate from 3-day-old alfalfa seedlings was purified and then assayed for biological activity with a nodABC-lacZ fusion in R. meliloti. Indentities of major nod inducers were established by spectroscopic analyses (ultraviolet/visible, proton nuclear magnetic resonance, and mass spectroscopy) and comparison with authentic standards. Major nod inducers, which were identified as 4',7-Dihydroxyflavone, 4'-7-dihydroxyflavanone, and 4,4'-dihydroxy-2'-methoxychalcone, were released from seedling roots at 54, 22, and 20 picomole.plant(-1).day(-1), respectively. Luteolin was not found in these root exudates.

存储条件: Powder: -20°C for 3 years | In solvent: -80°C for 1 year

溶解度: DMSO : 250 mg/mL (983.32 mM)
