title: Synthesis of certain puromycin analogues and their use in studying the peptidyl synthetase enzyme of e. coli and rat liver ribosomes.
abstract: The beta-alanyl and L-histidyl analogues of puromycin were synthesized chemically and tested for their ability to release [3H] N-acetylphenylalanine from its tRNA carrier in the rat liver and E. Coli ribosomal systems. Both analogues were found to be inactive in releasing [3H] N-acetylphenylalanine. Reasons for the inactivity of these compounds are discussed in relation to the structure of the puromycin molecule and the requirements for puromycin-like activity.
