Abstract

1,188,030. 1H-Pyrazolo-(3,4-d)pyrimidine-1- #-D-ribofuranosides. KYOWA HAKKO KOGYO CO. Ltd. 14 Sept., 1967 [16 Sept., 1966], No. 41998/67. Heading C2C. 1-#-D-Ribofuranosides of the formula wherein R 1 and R 2 represent H, OH or NH 2 , are obtained by culturing a micro-organism which is a yeast or a bacterium of the class Schizomycetes in a culture medium containing a compound of the formula The culture medium may also contain a carbon source, e.g. a carbohydrate, phosphoric acid compounds, a nitrogen source and inorganic salts. Conventional culturing and isolation techniques are employed. Examples describe the preparation of 4-hydroxy-4-amino and 6- amino - 4 - hydroxy - 1H - pyrazolo (3,4 - d)- pyrimidine - 1 - # - D - ribofuranosides using various bacteria.
