'''Sulforaphane''' is an [[organosulfur compound]] that exhibits anti[[cancer]], [[antidiabetic]], and [[antimicrobial]] properties. It is obtained from [[cruciferous vegetables]] such as [[broccoli]]. 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.

Sulforafane is an organosulfur compound that exhibits anticancer, antidiabetic, and antimicrobial properties. It is obtained from cruciferous vegetables such as broccoli. The enzyme myrosinase transforms glucorafanin, a glucosinolate, into sulforafane upon damage to the plant (such as from chewing). Young sprouts of broccoli and cauliflower are particularly rich in glucorafanin.

Occurrence and isolation

Sulforafane was identified in broccoli sprouts, which, of the cruciferous vegetables, have the highest concentration of sulforafane.[1] It is also found in brussel sprouts, cabbage, cauliflower, bok choy, kale, collards, chinese broccoli, broccoli raab, kohlrabi, mustard, turnip, radish, arugula, and watercress.

Possible medicinal properties

Consumption of broccoli sprouts has shown to be potentially effective at inhibiting Helicobacter pylori growth,[2][3] with sulforafane being at least one of the active agents.[4][5]

Sulforafane and dietary consumption of cruciferous vegetables are known to affect the action of drug-metabolizing enzymes in vitro and in preliminary human studies.[6] Although no side effects or direct drug interactions have been reported as of 2008, people taking prescription drugs are advised to consult a doctor before taking sulforafane or broccoli-sprout extracts.

The possible anticancer activity of sulforafane may be related to the induction of fase-II enzymes of xenobiotic transformation (such as quinone reductase and glutathione S-transferase), and enhancing the transcription of tumor suppressor proteins, possibly via inhibitory effects on histone deacetylase.[citation needed]

Sulforafane and diindolylmethane (another compound from Brassica vegetables) inhibit cancer growth in vitro and in experimental animals.[citation needed]

When applied topically, sulforafane may protect skin against UV radiation damage, and thus potentially against cancer.[7] Sulforafane may inhibit histone deacetylase (HDAC) activity.[8]

Sulforafane may protect the heart from inflammation that can lead to atherosclerosis.[9]
