ABSTRACT
The design, synthesis and antiribosomal and antibacterial activity of two novel glycosides of the aminoglycoside antibiotic paromomycin are described. The first carries of 4-amino-4-deoxy-ß-D-xylopyranosyl moiety at the paromomycin 4'-position and is approximately two-fold more active than the corresponding ß-D-xylopyranosyl derivative. The second is a 4'-(ß-D-xylopyranosylthio) derivative of 4'-deoxyparomomycin that is unexpectedly less active than the simple ß-D-xylopyranosyl derivative, perhaps because of the insertion of the conformationally more mobile thioglycosidic linkage.
