Trisaccharide mimetics of the aminoglycoside antibiotic neomycin.

A highly convergent approach for the chemical synthesis of eight structurally related trisaccharides that contain 3 to 5 amino groups has been described. Fourier-transformation ion cyclotron resonance mass spectrometry (FT-ICR MS) has been employed to determine the dissociation constants (Kd) for the binding of the trisaccharides to a prototypical fragment of 16S ribosomal RNA. A compound that contained a 4,6-dideoxy-4-amino-beta-D-glucopyranoside moiety at C-3 displayed binding in the low micromolar range. It was found that small structural changes of the saccharides resulted in large differences in affinity. The described structure-activity relationship is expected to be valuable for the development of novel antibiotics that target rRNA.

[The effect of Solcoseryl eye gel in combination with neomycin and bacitracin on the healing of corneal lesions after foreign body removal].

The effect of Solcoseryl on the healing rate of corneal lesions after foreign body removal was assessed in a double-blind study. Solcoseryl is a protein-free hemodialysate which is widely used to stimulate tissue repair processes. The healing rate was determined by means of photodocumentation which was complete in 82 out of 92 cases. The Solcoseryl group showed in significantly faster healing rate and a lower tendency to development of corneal opacities than the control group. No side-effects were observed which could be attributed to either of the drugs used in the study.
