found to have in general poor inhibitory activity against most enzymes. The 10-nor analogues however, showed 50–54% inhibition of α-L-rhamnosidase from Penicillium decumbens while one of these, 10-nor-steviamine, showed 51% inhibition of N-acetyl-β-D-glucosaminidase (from Jack bean) at the same concentration (760 μM).
报道了(-)-甜菊胺的简明合成及其类似物10-或-steviamine,10-或-ent - steviamine和5 -epi-ent- steviamine的合成。对这些化合物针对十二种糖苷酶(在143μgmL -1浓度下)进行了测试,发现它们对大多数酶的抑制活性通常较差。然而,10-或类似物对枯草青霉显示50-54%的α- L-鼠李糖苷酶抑制作用,而其中10-或-甜菊胺其中之一对N-乙酰基-β - D-氨基葡萄糖苷酶显示51%抑制作用(来自Jack豆)浓度相同(760μM)。
