  • We have examined the stacking interactions of N(2)-dimethyl-guanosine with the nucleosides, e.g., adenosine and cytidine, found adjacent to it in certain tRNA's, by the use of model compounds in which the trimethylene bridge was substituted for the ribose-phosphate-ribose linkage. From the hypochromism exhibited by synthetic 9-[3-(aden-9-yl)propyl]-2-dimethylaminopurine-6-one (IV) and by 9-[3-(cytos-1-yl)propyl]2-dimethylaminopurin-6-one in aqueous solution (VI) it is appearent that the… CONTINUE READING
