Abstract: A Rhodotorula rubra strain which reduces pentoxifylline 100% to the S-alcohol has been found. It is furthermore possible also to convert other oxoalkylxanthine derivatives into the corresponding S-alcohol. The microbiologically obtained S-(+) enantiomers can then be converted stereoselectively into the relevant R-(-) enantiomers. The corresponding S-alcohols and the R-alcohols obtained by enantioselective inversion of configuration bring about an increase in cerebral blood flow.

Abstract: The invention relates to MA of the formula I in which R , R , R and R independently of one another are a hydroxyl group or hydrogen and R is hydrogen, the bond between the C atom carrying the substituent R and the C atom carrying the substituent R being a single bond, or R and R independently of one another are a hydroxyl group or hydrogen and R is hydrogen, the bond between the C atom carrying the substituent R and the C atom carrying the substituent R being a double bond or R , R and R independently of one another are a hydroxyl group or hydrogen and R and R together are an oxo group. MA is hydroxylated or oxidised in the lipid side chain by microorganisms of the genus Cryptococcus and in this form is a starting compound for the preparation of moenomycin analogues which can be employed as medicaments. The moenomycin analogues have the following chemical structure: in which R to R have the abovementioned meanings.A

Abstract: Yeasts of the genus cryptococcus, preferably of the species C. Laurentii, form, in the presence of aminoacids, an L-aminoacid oxidase which stereospecifically converts L-aminoacids and their derivatives into the corresponding alpha -ketoacids. The immobilized cells are advantageously used for this conversion, which can also be used to resolve racemates.
