A number of cyclic peptides containing a positively charged ring composed of arginine residues attached to hydrophobic tail made of tryptophan residues through a lysine linker namely [R5K]W5, [R6K]W5, [R5K]W6, [R7K]W5, [R5K]W7, [R6K]W6, and [R7K]W7 were synthesized and evaluated as molecular transporters. The peptides were evaluated for their ability to deliver, fluorescence-labeled cell-impermeable negatively charged phosphopeptide (F′-GpYEEI), and fluorescent labeled anti-HIV drugs (F′-FTC and F′-d4T). The results indicated that the presence of positively …

The field of RNA therapeutics is currently undergoing both transformation and expansion. Specifically, research in lipid nanoparticle (LNP) based RNA therapeutics is gaining significant traction. Other research into mechanisms of gene regulation and manipulation, including siRNA and the CRISPR/Cas9 system have demonstrated the potential of RNA-based disease treatment. This work identifies a delivery system which can regulate expression of green fluorescent protein (GFP) in human embryonic kidney cells (HEK293) stably expressing GFP.
Analysis of siRNA-induced gene knockdown demonstrates that the current siRNA-LNP formulation is equally as effective as a commercially available transfection reagent, Lipofectamine RNAiMAX (RNAiMAX), which is designed specifically …

A number of amphiphilic cyclic peptides—[FR]4, [WR]5, and [WK]5—containing hydrophobic and positively-charged amino acids were synthesized by Fmoc/tBu solid-phase peptide methods and evaluated for their efficiency in intracellular delivery of siRNA to triple-negative breast cancer cell lines, MDA-MB-231 and MDA-MB-468, in the presence and absence of 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine (DOPE). Among the peptides, [WR]5, which contains alternate tryptophan (W) and arginine (R) residues, was found to be the most efficient in the delivery of siRNA by improving the delivery by more than 3-fold when compared to other synthesized cyclic peptides that were not efficient. The data also showed that co-formulation of [WR]5 …
