Four collections of Gal alpha1-4Gal derivatives were synthesised and evaluated as inhibitors of the PapG class II adhesin of uropathogenic Escherichia coli and of the P(N) and P(O) adhesins of Streptococcus suis strains. Galabiosides carrying aromatic structures at C1, methoxyphenyl O-galabiosides in particular, were identified as potent inhibitors of the PapG adhesin. Phenylurea derivatisation...

a mild, efficient and fast method for the trimethylsilyl (tms), tetrahydropyranyl (thp) and methoxymethyl (mom) protection of alcohols and phenols in the presence of sulfonated rice husk ash (rha-so3h) is reported. all reactions were performed at room temperature in high to excellent yields. all the products are separated and compared with authentic samples and/ or identified using different ty...
