Abstract
Breviscapine is one of the extracts of several flavonoids of Erigeron breviscapus. Scutellarin is the main active component of breviscapine, and the qualitative or quantitative criteria as well. Scutellarin and its analogs share a similar skeleton of the flavonoids. Breviscapine has been widely used in the treatment of cerebral infarction and its sequelae, cerebral thrombus, coronary heart disease (CHD), and angina pectoris. Breviscapine has a broad spectrum of pharmacological activities, such as increasing blood flow, improving microcirculation, dilating blood vessels, decreasing blood viscosity, promoting fibrinolysis, inhibiting platelet aggregation, and thrombosis formation, etc. In addition, breviscapine and its analogs have significant value for drug research and development because of the superiority of those significant bioactivities. Furthermore, an increasing number of pharmacokinetic studies have explored the mechanism of scutellarin and its analogs. To provide a comprehensive understanding of the current research on breviscapine, scutellarin, and the analogs, the structural features, distribution situation, preparation method, content determination method, clinical applications, pharmacological action as well as pharmacokinetics are summarized in the present review.

Abstract
Berberine hydrochloride (Brb) is a well-known herbal drug that holds a great promise in the recent years thanks to its various pharmacological actions. Currently, Brb is extensively researched as a natural surrogate with evidenced potentiality against numerous types of skin diseases including skin cancer. However, Brb's high aqueous solubility and limited permeability hinder its clinical topical application. In the current work, to enhance Brb's dermal availability, hydrophobic ion pairing approach was implemented combining the privileges of altering the solubility characteristics of Brb and the nanometric size that is usually gained during the ion pairing precipitation process. Sodium oleate (SO) was selected as the complexing agent due to its low toxicity and skin penetrating characteristics. Ion paired berberine oleate complex (Brb-OL) was prepared by simple precipitation technique. Brb-OL complex formation was confirmed by differential scanning calorimetry (DSC), infrared spectroscopy (IR), X-ray powder diffraction (XRD) and saturation solubility studies. It was found that Brb-OL complex formed at stoichiometric binding between oleate and Brb had an average particle size of 195.9 nm and zeta potential of -53.6 mV. The proposed Brb-OL showed 251-fold increase in saturation solubility in n-octanol which confirmed the augmented lipid solubility of the complex compared with free drug. Comparative in-vitro release study showed that Brb-OL complex had much slow and sustained release profile compared to that of free Brb. Furthermore, ex-vivo permeation study using rat skin revealed the enhanced skin permeation of ion-paired Brb-OL complex compared with free Brb. In-vivo study on healthy rats confirmed that topical application of hydrogels enriched with Brb-OL had superior skin penetration and deposition than free Brb as revealed by confocal microscope. Conclusively, ion pair formation between Brb and oleate lead to the formation of more lipophilic Brb-OL complex with nanometric particle size which is expected to be a major progressive step towards the development of a topical berberine formulation.

Abstract
The Biopharmaceutics Classification System (BCS) classifies pharmaceutical compounds based on their aqueous solubility and intestinal permeability. The BCS Class III compounds are hydrophilic molecules (high aqueous solubility) with low permeability across the biological membranes. While these compounds are pharmacologically effective, poor absorption due to low permeability becomes the rate-limiting step in achieving adequate bioavailability. Several approaches have been explored and utilized for improving the permeability profiles of these compounds. The approaches include traditional methods such as prodrugs, permeation enhancers, ion-pairing, etc., as well as relatively modern approaches such as nanoencapsulation and nanosizing. The most recent approaches include a combination/hybridization of one or more traditional approaches to improve drug permeability. While some of these approaches have been extremely successful, i.e. drug products utilizing the approach have progressed through the USFDA approval for marketing; others require further investigation to be applicable. This article discusses the commonly studied approaches for improving the permeability of BCS Class III compounds.

The molecular assembly of the ionic liquid/aliphatic carboxylic acid/aliphatic amine as effective and safety transdermal permeation enhancers. Eur J Pharm Sci 2016; 86:75-83.

Abstract
In spite of numerous advantages, transdermal drug delivery systems are unfeasible for most drugs because of the barrier effect of the stratum corneum. Ionic liquids were recently used to enhance transdermal drug delivery by improving drug solubility. In the present study, safe and effective ionic liquids for transdermal absorption were obtained as salts generated by a neutralization reaction between highly biocompatible aliphatic carboxylic acids (octanoic acid or isostearic acid) and aliphatic amines (diisopropanolamine or triisopropanolamine) (Medrx Co., Ltd., 2009). The mechanism of skin permeability enhancement by ionic liquids was investigated by hydrophilic phenol red and hydrophobic tulobuterol. Further, the skin permeation enhancing effect was remarkably superior in the acid excess state rather than the neutralization state. Infrared absorption spectrum analysis confirmed that ionic liquids/aliphatic carboxylic acid/aliphatic amine are coexisting at all mixing states. In the acid excess state, ionic liquids interact with aliphatic carboxylic acids via hydrogen bonds. Thus, the skin permeation enhancing effect is not caused by the ionic liquid alone. The "liquid salt mixture," referred to as a complex of ingredients coexisting with ionic liquids, forms a molecular assembly incorporating hydrophilic drug. This molecular assembly was considered an effective and safety enhancer of transdermal drug permeation.

Abstract
Ion paired solutions of methotrexate in L-arginine/water/propylene glycol systems were evaluated for their potential to enhance the permeation of methotrexate across rabbit nasal mucosa in vitro. The partition coefficient of methotrexate in the methotrexate: L-arginine ion paired systems was observed to be 24 times greater than that of the methotrexate system without L-arginine. The ion pair formation between methotrexate and L-arginine was confirmed by a decrease in the conductivity of the systems in the presence of propylene glycol, a dielectric constant reducing agent. The permeation of methotrexate across the rabbit nasal mucosa from the ion paired systems was observed to be significantly greater (p < 0.05) as compared to control systems of methotrexate solution in water and a sodium salt. Furthermore, a threefold increase in the flux of methotrexate was observed when propylene glycol was added to the ion paired systems. These results suggest that methotrexate: L-arginine ion paired systems have potential in improving the permeation of methotrexate across rabbit nasal mucosa and may form the basis for further development of an intranasal therapeutic system of methotrexate.

Abstract
The purpose of the present study was to investigate the permeation of glipizide (GP) and observe the effect of an interaction with amines as counter ions, including diethylamine, triethylamine, ethanolamine, diethanolamine, triethanolamine, N-(2-hydroxylethyl) piperidine. Permeation experiments were performed in vitro, using rat abdominal skin as a barrier. The lipophilic donor system consisting of isopropyl myristate (IPM) and ethanol (EtOH; EI system, 8:2) produced a marked enhancement of GP flux through rat skin. All the amines investigated in this study had performed an enhancing effect on GP flux, and triethylamine had the most potent enhancing effect on GP in the vehicle IPM:EtOH = 8:2(w/w). In the presence of counter ions, the solubility of GP in the donor solution (IPM:EtOH = 8:2) was increased and the log K (o/w) of GP was decreased, which may due to higher solubility of the GP in the IPM:EtOH = 8:2(w/w). (13)C NMR spectroscopy was used to identify the ion-pairing formation between GP and the respective counter ion. It was surprising that all the four enhancers examined, such as isopropyl myristate, propylene glycol, N-methyl-2-pyrrolidone, azone, and oleic acid, had no enhancing effect on the percutaneous permeation of GP. This study showed that the formation of ion-pairs between GP and counter ions is a useful method to promote the skin permeation of GP.

Abstract
A vast number of biologically active compounds await efficient delivery to become therapeutic agents. Lipidation has been demonstrated to be a convenient and useful approach to improve the stability and transport across biological membranes of potential drug molecules. The lipid core peptide (LCP) system has emerged as a promising lipidation tool because of its versatile features. This review discusses the progress in the development of the LCP system to improve cell permeability of nucleotides, physicochemical properties of potential drugs, and vaccine immunogenicity. Emphasis was put on the application of the LCP system to deliver antigens for the prevention of group A streptococcus infection, novel techniques of conjugation of target molecules to the LCP, and new alterations of the LCP system itself.
