Short oligomers of arginine, either alone or when conjugated to therapeutic agents or large biopolymers, have been shown to cross readily a variety of biological barriers (e.g., lipid bilayers and epithelial tissue). Molecular modeling suggests that only a subset of the side chain guanidinium groups of these transporters might be required for transport… (More)
Molecular transporters have the ability to deliver drugs and probe molecules into cells and tissues irrespective of their physical properties. We now report the design, synthesis, and biological evaluation of a new family of molecular transporters, guanidinylated oligocarbamates that enable exceptionally efficient uptake into cells and tissues. The… (More)
A new diterpenoid, tolypodiol (1), has been isolated from the terrestrial cyanobacterium Tolypothrix nodosa (HT-58-2) and identified by NMR and mass spectral analysis. The monoacetate derivative 2 was prepared. Tolypodiol (1) and its monoacetate derivative 2 show potent antiinflammatory activity in the mouse ear edema assay.
