Abstract
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 .beta.-glucosidase and sucrase and 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.
