Abstract
Anxiety disorders are the most common mental diseases and can greatly disrupt everyday life. Although there has been substantial research on anxiety disorders, novel therapeutics are needed. Neuropeptide S (NPS) is a potential therapeutic candidate owing to its strong anxiolytic activity; however, some disadvantages, such as its poor metabolic stability and inability to cross the blood-brain barrier (BBB), limit its use in the clinic. Herein, inspired by nose-to-brain drug delivery strategies, an endogenous 20-amino-acid-long mNPS peptide was modified by incorporating palmitic acid into its functional Lys12 side chain (M-3), which was expected to facilitate nose-to-brain penetration and exert a prolonged anxiolytic-like effect compared to mNPS. We found that M-3 assembled into nanofibers that retained the bioactivity of NPS and exhibited obvious improvements in metabolic stability. Notably, as expected, self-assembled M-3 was able to penetrate into the brain and exert anxiolytic effects. The elevated plus-maze (EPM) results further revealed that M-3 could produce prolonged anxiolytic-like effects in mice. In vivo imaging studies revealed that self-assembled M-3 could be efficiently transported from the nasal cavity to the brain. Furthermore, when intranasally administered, this molecule exhibited a significantly prolonged anxiolytic-like effect, which further illustrated that this molecule has a potent nose-to-brain penetration in vivo. Overall, this self-assembled nanofiber showed potent nose-to-brain penetration ability and prolonged bioactivity.

Abstract
In the present study, we examined the potential of cell-penetrating peptide (CPP)-based intranasal drug delivery for the treatment of localized nasal diseases. Many charged or non-hydrophobic drugs have difficulty penetrating into the nasal epithelium due to intrinsic membrane impermeability and rapid mucociliary clearance in the nasal cavity. To treat chronic rhinosinusitis with nasal polyps (CRSwNP), one of the most common localized nasal diseases, we conjugated resveratrol (RSV) to an amphiphilic α-helical leucine (L)- and lysine (K)-rich CPP (LK) and intranasally delivered it to the interior of nasal epithelial cells for inhibiting epithelial-to-mesenchymal transition (EMT) caused by hypoxia-inducible factor 1α. The RSV-LK conjugate could penetrate into the nasal epithelium and efficiently inhibit EMT, nasal polyp formation, epithelial disruption, and related inflammation in an eosinophilic CRSwNP mouse model, at 10-fold lower doses and with 3-fold less frequent administration than free RSV. Due to the rapid penetration into the nasal epithelium and the therapeutic effect of the RSV-LK conjugate at much lower doses than free RSV, this CPP-based delivery system, with the ability to overcome the tight nasal epithelial barrier, may provide a new strategy for the treatment of localized nasal diseases without the systemic side effects of cargo drugs.

Intranasal Coadministration of a Diazepam Prodrug with a Converting Enzyme Results in Rapid Absorption of Diazepam in Rats. J Pharmacol Exp Ther 2019; 370:796-805.

Abstract
Intranasal administration is an attractive route for systemic delivery of small, lipophilic drugs because they are rapidly absorbed through the nasal mucosa into systemic circulation. However, the low solubility of lipophilic drugs often precludes aqueous nasal spray formulations. A unique approach to circumvent solubility issues involves coadministration of a hydrophilic prodrug with an exogenous converting enzyme. This strategy not only addresses poor solubility but also leads to an increase in the chemical activity gradient driving drug absorption. Herein, we report plasma and brain concentrations in rats following coadministration of a hydrophilic diazepam prodrug, avizafone, with the converting enzyme human aminopeptidase B Single doses of avizafone equivalent to diazepam at 0.500, 1.00, and 1.50 mg/kg were administered intranasally, resulting in 77.8% ± 6.0%, 112% ± 10%, and 114% ± 7% bioavailability; maximum plasma concentrations 71.5 ± 9.3, 388 ± 31, and 355 ± 187 ng/ml; and times to peak plasma concentration 5, 8, and 5 minutes for each dose level, respectively. Both diazepam and a transient intermediate were absorbed. Enzyme kinetics incorporated into a physiologically based pharmacokinetic model enabled estimation of the first-order absorption rate constants: 0.0689 ± 0.0080 minutes-1 for diazepam and 0.122 ± 0.022 minutes-1 for the intermediate. Our results demonstrate that diazepam, which is practically insoluble, can be delivered intranasally with rapid and complete absorption by coadministering avizafone with aminopeptidase B. Furthermore, even faster rates of absorption might be attained simply by increasing the enzyme concentration, potentially supplanting intravenous diazepam or lorazepam or intramuscular midazolam in the treatment of seizure emergencies.
