Thiourea and vinyl sulfoxide derivatives were designed based on the structures of sulforaphane and gallic acid, prepared and tested for HO-1 inducing activity as a measure of Nrf2 activation, and inhibitory effect on NO production as a measure of anti-inflammatory activity. Both series of compounds showed moderate activity on HO-1 induction, and no inhibitory effect on NO production. Interestingly the thiourea compound 6d showed better HO-1 induction (71% SFN) than the corresponding isothiocyanate compound 6a (55% SFN). Overall, it seemed that more efficient electrophile is needed to get more effective Nrf2 activator.
根据莱菔硫烷和没食子酸的结构设计了硫脲和乙烯基亚砜衍生物,制备并测试了作为 Nrf2 活化指标的 HO-1 诱导活性和作为抗炎指标的 NO 生成抑制作用。这两个系列的化合物对 HO-1 的诱导都表现出适度的活性,而对 NO 的产生没有抑制作用。有趣的是,硫脲化合物 6d 对 HO-1 的诱导作用(71% SFN)优于相应的异硫氰酸盐化合物 6a(55% SFN)。总之,要获得更有效的 Nrf2 激活剂,似乎需要更高效的亲电子体。
