- Abstract
- Zonula occludens toxin has been shown to reversibly open tight junctions in endothelial and epithelial cells.
The purpose of this study was to evaluate the permeation activity of C-terminal amidated fragment of Zonula occludens toxin and co-administration with a fructose polymer on enhancing the nasal and duodenal administration of atenolol. The C-terminal amidated peptide (Phe-Cys-Ile-Gly-Arg-Leu-NH2) resulted in statistically significant improvement in permeation of atenolol compared to the control in both nasal and duodenal administration. Also, the permeability enhancing effect of the C-terminal amidated peptide was significantly promoted by the fructose polymer, levan. C-terminal amidated peptide together with the addition of levan may be promising as a tight junction modulated permeation enhancer, and allow the development of the mucosal drug delivery of low bioavailability therapeutic agents.
