The sublingual frenulum area, the thin, vascular tissue connecting the underside of the tongue to the floor of the mouth, is the target
Schoenenberger and Monnier reported in the Proceedings of the National Academy of Sciences USA the isolation, sequence determination and synthesis of the active material, identified as the nonapeptide Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu, and demonstrated that intraventricular infusion of the synthetic compound in rabbits reproduced delta- and spindle-EEG enhancement under double-blind conditions (Schoenenberger & Monnier, 1977)

Based on the sequence requirements in penetratin for transduction, such as hydrophobicity, amphipathicity, basicity, and the chain length (Khafagy et al., 2010a), a modified peptide designated as shuffle (R,K fix) 2 (RWFKIQMQIRRWKNKK) that exhibits safe and enhanced insulin delivery was developed (Khafagy et al., 2010a)
