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。

A compound of formula (I):
compositions and medicaments containing the same as well as processes for the preparation and use of such compounds, compositions and medicaments, particularly in diseases associated with inappropriate Aurora activity.
A novel cancer cell and lysosome dual-targeted photosensitizer (PS) termed by BMP was developed for fluorescenceimaging and photodynamictherapy (PDT). BMP consists of a porphyrin(Zn) core with appropriate singlet-triplet state distribution enables it to function as an imaging agent as well as a PS, a biotin moiety that can target cancer cells, and a morpholine group specific to lysosomes.

一种新型癌细胞和溶酶体双靶向光敏剂(PS)(称为BMP )被开发用于荧光成像和光动力治疗(PDT)。BMP由具有适当单线态-三线态分布的卟啉 (Zn) 核心组成,使其能够充当显像剂以及 PS、可靶向癌细胞的生物素部分和溶酶体特异性的吗啉基团。细胞内实验表明,双靶向光敏剂BMP可以更好地在癌细胞中积累,并随后定位在溶酶体细胞器内。照射后,BMP可以产生红色荧光发射(Φ em = 6.3%)和单线态氧(1 O 2,Φ Δ = 55%),分别用于细胞成像和 PDT 的双重功能。值得注意的是,与正常细胞(BEAS-2B 细胞)相比,BMP对癌细胞(A549 细胞)表现出更高的光细胞毒性。重要的是,BMP产生的1 O 2诱导溶酶体氧化损伤,随后引发 A549 细胞的细胞死亡,表现为形态完整性的丧失和细胞破裂。
