Synthesis and antibacterial activities of amphiphilic neomycin B-based bilipid conjugates and fluorinated neomycin B-based lipids.
Investigating the effect of lipid hydrophobicity on the activity of amphiphilic neomycin B conjugates, six polycationic amphiphiles (PAs) were created. Four of the new compounds incorporated either palmitic or arachidic di-lipid lysine tails, while two had single fluorinated undecanoic acid tails. The basicity of half of the compounds was increased through the incorporation of six guanidine moi...
متن کاملTotal synthesis of largamide B.
Total synthesis of the cyanobacterial metabolite largamide B and the disproval of its originally assigned stereochemistry as well as confirmation of the revised stereochemistry are reported.
متن کاملTotal Synthesis of Paecilomycin B.
Starting from the glucose-derived δ-lactone and the functionalized aryl bromide, the first total synthesis of naturally occurring paecilomycin B was achieved via functionalized aryl-β-C-glycoside synthesis using 2,4,6-triisopropylphenyllithium under Barbier-type reaction conditions and ring-closing metathesis as the key steps.
متن کاملTotal synthesis of (+/-)-neovibsanin B.
(+/-)-Neovibsanin B was synthesized based on a DMI-accelerated intramolecular Diels-Alder reaction followed by oxy-Michael addition-lactonization. The synthetic (+/-)-neovibsanin B induced similar morphological changes in NGF-mediated PC12 cells compared with natural (+)-neovibsanin B.
متن کاملTotal Synthesis of Propolisbenzofuran B.
The first total synthesis of propolisbenzofuran B, a bioactive natural product isolated from honeybee propolis resin, is reported. The convergent synthesis makes use of a silicon-tether controlled oxidative ketone-ketone cross-coupling and a novel benzofuran-generating cascade reaction to deliver the core structure of the natural product from readily prepared precursors.
