Sulforaphane is a cruciferous vegetable-derived isothiocyanate with promising antitumor, chemopreventive and therapeutic activities, it inhibits TPA-induced NF-κB activation and COX-2 expression in MCF-10A cells by blocking two distinct signaling pathways mediated by ERK1/2-IKKα and NAK-IKKβ. Sulforaphane may exert a significant neuroprotective effect on cholinergic deficit and cognitive impairment, it also has anti-inflammatory effect, at least ,in part,associated with interfering with the NF-κB pathway. (R)-sulforaphane is a sulforaphane in which the sulfinyl group has R configuration. Naturally occurring compound found in brocolli that acts as a potent inducer of phase II detoxification enzymes. It is an enantiomer of a (S)-sulforaphane.
