CHARACTERIZATIONS AND SOME CHEMICAL REACTIONS OF PERIODATE-OXIDIZED NUCLEOSIDES
Phenylhydrazine reacts with the periodate oxidation products of adenosine, guanosine, uridine, and cytidine to form bisphenylhy-drazones, which were isolated and characterized. These substances react further with phenylhydrazine to form adenine, guanine, uracil, and cytosine and 2- and 3- carbon fragments. Sodium borohydride reduces both aldehyde groups of the oxidized nucleosides when the reaction is carried out under alkaline conditions, but selective reduction of the aldehyde group distal to the purine or pyrimidine ring occurs under slightly acidic conditions. Ion exchange and paper chromatographic methods were developed for the examination of the dialdehydes and the corresponding reduction products were obtained from them. Evidence is presented indicating that the acid hydrolysis of the completely reduced products. the tri-alcohols, is probably initiated at the glycosidic linkage. A new micro method for measuring and removing periodate and iodate essentially in one step was developed. (auth)
