Multicomponent Approach to Homo-and Hetero-Multivalent Glycomimetics Bearing Rare Monosaccharides

We applied a multicomponent approach to access a library of densely functionalized homo-and hetero-multivalent glycomimetics comprising aldehyde, amine, and isocyanide components related to isopropylidene-protected d-fructose, l-sorbose, d-galactose, and d-Allose. Passerini products were obtained in very good yields (up to 78%) and high diastereoselectivities (up to 98:2). Three types of products were obtained by the Ugi reaction; along with the "classical" four-component product, α-Acylaminoamides, a three-component α-Aminoamides, and a four-component α-Aminoacylamides were isolated. The presence of multiple pathways is rationalized by the structure of the imidate intermediate, mainly influenced by the amine component.

Comparison of sulfamate and sulfamide groups for the inhibition of carbonic anhydrase-II by using topiramate as a structural platform

This paper examines the relative effectiveness of sulfamate and sulfamide groups for the inhibition of carbonic anhydrase-II (CA-II). Topiramate (1) and its sulfamide analogue 4, and 4,5-cyclic sulfate 6 and its sulfamide analogue 5, were compared for inhibition of human CA-II. A colorimetric assay, based on the pH shift that accompanies hydration of carbon dioxide, and an esterase assay were used. For these bioisosteric pairs, 1/4 and 6/5, the sulfamate compound was markedly more potent than its sulfamide counterpart. A similar, large difference in potency was also observed for the sulfamate/sulfamide pairs 14/15 and 16/17. These results indicate that the sulfamide moiety is not particularly suitable for obtaining potent carbonic anhydrase inhibition. A discussion of this structure-activity relationship with respect to the interactions of 1 and 6 with CA-II from published X-ray data is presented. A metabolic acidosis study was performed in rats with 1, 4, 6, and 2, and the results are discussed with respect to the degree of inhibition of CA-II in vivo.
