cell permeability, we designed and synthesized methoxylated 4-(1-hydroxy-naphthalen-2-yl)-2-phenyl-2,3-dihydro-1,5-benzothiazepine derivatives (Fig. 1(D)). However, flavonoids bearing a benzothiazepine skeleton have rarely been reported, even though their design and synthesis are of interest because of their biological diversity. Furthermore, because the 1H and 13C NMR, and high resolution mass spectrometric
苯并噻嗪是一种含氮和硫的杂环化合物。通过改变双键和苯环的位置,可以设计出多种衍生物。2,3-Dihydro1,5-benzothiazepine(也称为 2,3-dihydro[b][1,4]thiazepine)衍生物具有多种生物活性,包括对 α-葡萄糖苷酶、脲酶、胆碱酯酶和丁酰胆碱酯酶的抑制作用,以及对瞬时受体电位锚蛋白 1 (TRPA1) 受体的激动活性(图 1(A))。当两个苯环连接在 C-2 和 C-4 位置时,可以衍生出含有 C6-C3-C6 骨架的 2,4-diphenyl2,3-dihydro-1,5-benzothiazepine(图 1(B) )。黄酮类化合物作为次生代谢物存在于各种植物中,由 C6-C3-C6 骨架组成(图 1(C))。由于甲氧基化和萘基可以增加细胞区室化和细胞通透性,我们设计并合成了甲氧基化 4-(1-hydroxy-naphthalen-2-yl)-2-phenyl-2
