Synthesis and in vitro inhibition properties of oligonucleotide conjugates carrying amphipathic proline-rich peptide derivatives of the sweet arrow peptide (SAP).

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
In this study, a series of derivatives of the amphipathic proline-rich sweet arrow peptide (SAP) were covalently linked to antisense oligonucleotides designed to inhibit Renilla luciferase gene. Oligonucleotide-peptide conjugates carrying lysine (Lys) and ornithine (Orn) residues were prepared using the stepwise approach by assembling first the peptide sequence followed by the assembly of the DNA molecule. The resulting Lys, Orn-conjugates were transformed to the corresponding arginine and homoarginine oligonucleotide-peptide conjugates by reaction with O-methylisourea. The introduction of the SAP at 3'-termini of a phosphorothioate oligonucleotide did not affect the ability to inhibit gene expression when transfected with lipofectamine. However, these conjugates were not able to enter cells without transfecting agent. Further studies using SAP as a transfection agent showed promising results for the conjugates carrying the Orn-SAP. All conjugates showed high duplex stabilities.
