Tetramines containing the tetramethylene or benzene-1,4-dimethylene linkers are more potent amannosidase inhibitors than simple (2R, 3R, 4S)-2-aminomethylpyrrolidine- 3,4-diols. Triamines such as (2S, 3R, 4S)-bis(3,4-dihydroxy-pyrrolidin-2-ethyl) amine were also prepared and shown to be better alpha-mannosidase inhibitors than (2S, 3R, 4S)- 2-(2-aminoethyl) pyrrolidin-3,4-diol.3 deoxy derivativesglycosidase inhibitorsmannostatin-abiologicalevaluationn-butyldeoxynojirimycinadvanced malignanciesprocessinginhibitorpotentswainsoninegalactosidasetext::journal::journal article::research article
