We designed hexavalent antagonists of the fucose-binding protein FleA from the pathogenic fungi A. fumigatus. An optimized chemical probe further evidenced the role of FleA in a fungistatic process mediated by epithelial cells.
Triazole-Containing Dendrimer-like Core Cross-Linked Micelles that Stabilize Pd Nanoparticles as Heterogenized Homogeneous Catalysts for Room-Temperature Suzuki-Miyaura Reactions in Water
catalysts (e.g., dendrimer‐stabilized metal nanoparticles) have received much attention in recent years. Here, we develop a new triazole‐containing dendrimer‐like corecross‐linkedmicelle (DCCM) stabilized Pd nanoparticles as a highly efficient heterogenized homogeneous catalyst for the Suzuki–Miyaura reaction. Both arylboronic acids and iodobenzenes with diverse electronic properties performed with excellent
Intramolecular allylboration of γ-(ω-formylalkoxy)allylboronates for syntheses of trans- or cis-2-(ethenyl)tetrahydropyran-3-ol and 2-(ethenyl)oxepan-3-ol
give 3-alkoxy-1-alkenylboronates 5. The latter gave (E)-3-alkoxyallylboronates (8: (E)-(MeO)2CHCH2(CH2)nCH2OCHCHCH2Bpin, n=1–3) when they were subjected to iridium-catalyzed isomerization of the double bond. The corresponding (Z)-isomers 10 were synthesized by nickel-catalyzed isomerization of 5. Both allylboronates underwent intramolecular allylboration leading to the formation of trans-2-(ethen

The present invention relates to a compound bearing at least two fucose moieties for its use as a drug in the prevention or treatment of infections caused by Aspergillus spp, said compound having a molecular weight comprised from 0.6 to 340 kDa, in particular from 0.6 to 2 kDa or from 1 to 7 kDa or from 2 to 10 kDa or from 5 to 340 kDa.
Escherichia coli DNAtopoisomeraseIinhibition, binding to B-DNA duplex, and antibacterial activity has been evaluated. Bisbenzimidazoles with alkynyl side chains display excellent E. coli DNAtopoisomeraseIinhibition properties with IC50 values <5.0 μM. Several bisbenzimidazoles (3, 6, 7, 8) also inhibit RNA topoisomerase activity of E. coli DNAtopoisomeraseI. Bisbenzimidazoles inhibit bacterial growth
