ObjectivesThe relationship between polyphenol constituents, antioxidant properties of aqueous and methanol extracts of green tea (Camellia sinensis), the herbal teas, rooibos (Aspalathus linearis) and honeybush (Cyclopia spp.), against skin cell viability was investigated in vitro.
MethodsThe effect of extracts, characterised in terms of polyphenol content and antioxidant properties, on cell viability...
A disaccharide analogue (A4 = 13c) of moenomycin A lacking the OH group in the 4-position of the uronic acid moiety has been synthesized using the Saito deoxygenation reaction as key step. 13c does not inhibit the transglycosylase (PBP 1b), a key enzyme in the biosynthesis of bacterial peptidoglycan. The result demonstrates the importance of this OH group for the binding of disaccharide moenomycin...
