Description: Sulforaphane, also known as BroccoPhane; Sulphoraphane; Detoxophane, is a naturally-occurring phytochemical belonging to the class of isothiocyanates. As the aglycone metabolite of glucosinolate glucoraphanin (sulforaphane glucosinolate), sulforaphane acts as an antioxidant and potent stimulator of endogenous detoxifying enzymes. This agent displays anticarcinogenic properties due to its ability to induce phase II detoxification enzymes, such as glutathione S-transferase and quinone reductase, thereby providing protection against certain carcinogens and toxic, reactive oxygen species. Broccoli sprouts contain large amounts of sulforaphane, which is also found in other cruciferous vegetables including cabbage and kale.

Biological target: Sulforaphane is an inducer of Nrf2 and is also an inhibitor of histone deacetylase (HDAC) and NF-κB.
In vitro activity: H9c2 rat myoblasts were pre-treated with sulforaphane and its effects on cardiotoxicity were then examined. The results revealed that the pre-treatment of H9c2 rat myoblasts with sulforaphane decreased the apoptotic cell number (as shown by trypan blue exclusion assay) and the expression of pro-apoptotic proteins (Bax, caspase-3 and cytochrome c; as shown by western blot analysis and immunostaining), as well as the doxorubicin-induced increase in mitochondrial membrane potential (measured by JC-1 assay). Furthermore, sulforaphane increased the mRNA and protein expression of heme oxygenase-1 (HO-1, measured by RT-qPCR), which consequently reduced the levels of reactive oxygen species (ROS, measured using MitoSOX Red reagent) in the mitochondria which were induced by doxorubicin. The cardioprotective effects of sulforaphane were found to be mediated by the activation of the Kelch-like ECH-associated protein 1 (Keap1)/NF-E2-related factor-2 (Nrf2)/antioxidant-responsive element (ARE) pathway, which in turn mediates the induction of HO-1. Taken together, the findings of this study demonstrate that sulforaphane prevents doxorubicin-induced oxidative stress and cell death in H9c2 cells through the induction of HO-1 expression.

In vivo activity: N-butyl-N-(4-hydroxybutyl)-nitrosamine is used to induce bladder cancer in male C57BL/6 mice, with or without sulforaphane (SFN) for 23 weeks. SFN ameliorates the histological changes characteristic of bladder cancer, resulting in fewer submucosal capillaries. SFN normalizes gut microbiota dysbiosis in mice with BBN-induced bladder cancer with a significant increase in Bacteroides fragilis and Clostridium cluster I. SFN also increases butyric acid levels in the mouse colon, and repairs the injury to the mucosal epithelium of the colon and cecum through the upregulation of the expression of tight junction proteins and GLP2. SFN greatly decreases the release of cytokines (IL-6) and secretory immunoglobulin A in the mice with bladder cancer. Reference: Mol Nutr Food Res. 2018 Dec;62(24):e1800427.

Additional Information

Sulforaphane exhibits anticancer, antidiabetic, and antimicrobial properties in experimental models. It is obtained from cruciferous vegetables such as broccoli, Brussels sprouts or cabbages. The enzyme myrosinase transforms glucoraphanin, a glucosinolate, into sulforaphane upon damage to the plant (such as from chewing). Young sprouts of broccoli and cauliflower are particularly rich in glucoraphanin. [source:]
