Synthesis of 4-O-(4-Amino-4-deoxy-β-D-xylopyranosyl)paromomycin and 4-S-(β-D-Xylopyranosyl)-4-deoxy-4'-thio-paromomycin and Evaluation of their Antiribosomal and Antibacterial Activity.


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-β-D-xylopyranosyl moiety at the paromomycin 4'-position and is approximately two-fold more active than the corresponding β-D-xylopyranosyl derivative. The second is a 4'-(β-D-xylopyranosylthio) derivative of 4'-deoxyparomomycin that is unexpectedly less active than the simple β-D-xylopyranosyl derivative, perhaps because of the insertion of the conformationally more mobile thioglycosidic linkage.
