A new series of acridine-9-carboxamide-1,2,3-triazole derivatives I [R = H, 2-Me, 4-O₂N, etc.] were designed, synthesized and evaluated as novel α-glucosidase inhibitors. Compounds I were designed by combination of effective moieties from potent α-glucosidase inhibitors. Most of the synthesized compounds I were more potent than standard inhibitor acarbose. Among the synthesized compounds, the most potent compounds were I [R = 3-Br, 4-Br, H] with IC₅₀ values of 120.2 ± 1.0, 151.1 ± 1.4, and 157.6 ± 1.6μM, resp. (IC₅₀ value of acarbose = 750.0 ± 10.0μM). Docking study of the most potent compounds I [R = H, 3-Br, 4-Br] reported that these compounds formed stable complexes with α-glucosidase active site. Anti-α-amylase assay of compounds I [R = H, 3-Br, 4-Br] was performed and no activity was observed, meanwhile in-vitro cytotoxicity assay of the latter compounds revealed that these compounds were not cytotoxic toward human normal (HDF) and cancer (MCF-7) cell lines.

A new series of 1,2,3-triazole-(thio)barbituric acid hybrids 8a-n was designed and synthesized on the basis of potent pharmacophores with urease inhibitory activity. Therefore, these compounds were evaluated against Helicobacter pylori urease. The obtained result demonstrated that all the synthesized compounds, 8a-n, were more potent than the standard urease inhibitor, hydroxyurea. Moreover, among them, compounds 8a, 8c-e, 8g,h, and 8k,l exhibited higher urease inhibitory activities than the other standard inhibitor used: thiourea. Docking studies were performed with the synthesized compounds Furthermore, mol. dynamic simulation of the most potent compounds, 8e and 8l, showed that these compounds interacted with the conserved residues Cys592 and His593, which belong to the active site flap and are essential for enzymic activity. These interactions have two consequences: (a) blocking the movement of a flap at the entrance of the active site channel and (b) stabilizing the closed active site flap conformation, which significantly reduces the catalytic activity of urease. Calculation of the physicochem. and topol. properties of the synthesized compounds 8a-n predicted that all these compounds can be orally active. The ADME prediction of compounds 8a-n was also performed.

Andrews, Mary Katherine;Liu, Xinyu;Gellman, Samuel H. research published 《 Tailoring Reaction Selectivity by Modulating a Catalytic Diad on a Foldamer Scaffold》, the research content is summarized as follows. Use of a tunable mol. scaffold to align a reactive diad for bifunctional catalysis can reveal relationships between functional group identity and reactivity that might otherwise be impossible to identify. Here we use an α/β-peptide helix to show that an aligned pair of primary amine groups is uniquely competent to catalyze crossed aldol condensations with an aryl aldehyde as the electrophile. Geometrically similar diads in which one amine group is secondary, or both are secondary, are good catalysts for other types of aldol condensations but not those involving an aryl aldehyde. Catalytic efficacy requires β-amino acid residues that are preorganized for helix formation via cyclic constraint. Conventional peptides (exclusively α-amino acid residues) that display the primary amine diad are poor catalysts, which highlights the critical role of the foldamer scaffold.
