5-Amino-1-(hydroxymethyl)cyclopentane-1,2,3,4-tetraol and 2-amino-4-(hydroxymethyl)-3a,5,6,6a-tetrahydro-4H-cyclopent[d]oxazole-4,5,6-triol, which have the ability to inhibit the activity of sugar hydrolases, especially β-glucosidase and sucrase, and which can thus be used for the treatment and prophylaxis of tumorous conditions, AIDS, diabetes and obesity, can be prepared by hydrolysis of trehazolin. 2-Amino-4-(hydroxymethyl)-3a,5,6,6a-tetrahydro-4H-cyclopent[d]oxazole-4,5,6-triol can also be prepared by fermentation using newly isolated strains Micromonospora sp. SANK 62390, FERM BP-3521 and Amycolatopsis sp. SANK 60791, FERM BP-3513.
5-氨基-1-(羟甲基)环戊烷-1,2,3,4-四醇和 2-氨基-4-(羟甲基)-3a,5,6,6a-四氢-4H-环戊并[d]恶唑-4,5,6-三醇具有抑制糖水解酶活性的能力、通过水解曲唑啉可以制备 2-氨基-4-(羟基)-4H-环戊并[d]恶唑-4,5,6-三醇,它具有抑制糖水解酶活性的能力,特别是β-葡萄糖苷酶和蔗糖酶,因此可用于治疗和预防肿瘤、艾滋病、糖尿病和肥胖症。2-Amino-4-(hydroxymethyl)-3a,5,6,6a-tetrahydro-4H-cyclopent[d]oxazole-4,5,6-triol 也可以使用新分离的菌株 Micromonospora sp.
