Glucoraphanin 是一种硫代葡萄糖苷，存在于十字花科蔬菜中，是 Nrf2 诱导剂 sulforaphane 的前体，sulforaphane有抗氧化、抗炎、抗癌作用。

Glucoraphanin, the precursor of the widely extolled chemopreventive agent sulforaphane found in broccoli, has antioxidant activity.

Glucoraphanin reduces weight gain and increases energy expenditure in HFD-fed mice. Glucoraphanin can improve insulin sensitivity and glucose tolerance in HFD-fed mice. However, Glucoraphanin does not exert antiobesity and insulin-sensitizing effects in Nrf2?/? Mice. Glucoraphanin blocks HFD-induced reduction of Ucp1 protein levels in white adipose depots of wild-type mice but not in Nrf2?/? mice. Glucoraphanin alleviates HFD-induced hepatic steatosis and oxidative stress. Glucoraphanin suppresses HFD-induced proinflammatory activation of macrophages in the liver and adipose tissue [1]. Mice with pellets including 0.1% Glucoraphanin (GF) significantly attenuates the decreased social avoidance time in stressed mice. In the 1% sucrose preference test (SPT), treatment with pellets including 0.1% GF significantly attenuates the decreased sucrose preference of stressed mice [2].

Male C57BL/6JSlc mice are 7 weeks of age. The Nrf2 knockout (Nrf2?/?) mouse strain is used in the assay. After 1 week of acclimation, mice are fed normal chow (NC) (containing 2.2% dextrinized cornstarch, 10% kcal from fat), NC containing 0.3% glucoraphanin (NC-GR) (containing 2.2% extract powder), an HFD (containing 2.2% dextrinized cornstarch, 60% kcal from fat), or an HFD containing 0.3% glucoraphanin (HFD-GR) (containing 2.2% extract powder) for 14 weeks. Both the NC and the HFD containing cornstarch or glucoraphanin are prepared. All mice studied are maintained on a 12-h light/dark cycle at 24-26°C with free access to water and food [1].
