naturally occurring sulfonium ion salacinol (1), a potent alpha-glucosidase inhibitor isolated from the Ayruvedic medicine Salacia reticulata, was synthesized and its inhibitory activity against alpha-glucosidase tested. Substitution of the sulfur atom in 1 with a nitrogen reduced the activity considerably. The solid-state stereostructure of the related compound (5) was determined on the basis of single crystal
合成了天然sulf离子水杨醇(1)的氮类似物4(一种从Ayruvedic药Salacia reticulata中分离出的有效α-葡萄糖苷酶抑制剂),并测试了其对α-葡萄糖苷酶的抑制活性。用氮取代1中的硫原子会大大降低活性。根据单晶X射线测量确定相关化合物(5)的固态立体结构。
