Biomed Pharmacother 2023; 164:114668. [PMID: 37321057 DOI: 10.1016/j.biopha.2023.114668] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2023] [Revised: 04/02/2023] [Accepted: 04/06/2023] [Indexed: 06/17/2023] Open
Abstract
BACKGROUND Chiral drugs generally exhibit differences in activity because they bind differently to their target receptor. The Chinese medicine borneol ('Bing Pian' in Chinese) is a bicyclic monoterpenoid with a wide range of biological activities. Three kinds of Chinese medicines comprising borneol are used clinically, namely, L-Borneolum ('Ai Pian' in Chinese), Borneolum ('Tian Ran Bing Pian' in Chinese), and synthetic borneol ('He Cheng Bing Pian' in Chinese). The three kinds of borneol have different stereochemical configurations, but their clinical uses are nearly identical, and their prices vary widely. However, there is no clear rational basis for the selection of these kinds of borneol in clinical applications. PURPOSE The purpose of this study was to clarify differences in the biological activity, safety, and structure-activity relationship of the three kinds of borneol. METHODS 'borneol', 'Bing Pian', 'Ai Pian', 'Tian Ran Bing Pian', and 'He Cheng Bing Pian' were selected as keywords to search for and extract relevant literature in the CNKI, PubMed, and Google Scholar databases up to November 2022. RESULTS L-borneol has better potential in cerebrovascular diseases. The three kinds of borneol have stronger penetration-promoting effects on hydrophilic drugs. L-borneol and isoborneol promote intestinal mucosal absorption of drugs via bidirectional regulation of P-glycoprotein. D-borneol exhibits better antitumour sensitizing effects than L-borneol. L-borneol exhibits better inhibition of bacterial adhesion because of its C2 chiral centre. Synthetic borneol is less safe. CONCLUSION L-borneol has excellent potential in many aspects, has various sources, and can effectively replace expensive D-borneol in some applications.

Abstract
Skin's effectiveness as a barrier to permeation of water and other chemicals rests almost entirely in the outermost layer of the epidermis, the stratum corneum (SC), which consists of layers of corneocytes surrounded by highly organized lipid lamellae. As the only continuous path through the SC, transdermal permeation necessarily involves diffusion through these lipid layers. The role of the SC as a protective barrier is supported by its exceptional lipid composition consisting of ceramides (CERs), cholesterol (CHOL), and free fatty acids (FFAs) and the complete absence of phospholipids, which are present in most biological membranes. Molecular simulation, which provides molecular level detail of lipid configurations that can be connected with barrier function, has become a popular tool for studying SC lipid systems. We review this ever-increasing body of literature with the goals of (1) enabling the experimental skin community to understand, interpret and use the information generated from the simulations, (2) providing simulation experts with a solid background in the chemistry of SC lipids including the composition, structure and organization, and barrier function, and (3) presenting a state of the art picture of the field of SC lipid simulations, highlighting the difficulties and best practices for studying these systems, to encourage the generation of robust reproducible studies in the future. This review describes molecular simulation methodology and then critically examines results derived from simulations using atomistic and then coarse-grained models.

Int J Pharm 2022; 612:121377.

Abstract
At present, how the release kinetics of permeation enhancers affected their enhancement efficacy on drug skin absorption and its molecular mechanisms remained unclear. Herein, the release kinetics of permeation enhancer (Plurol Oleique CC (POCC)) which involved release percent (PR), release duration (RD) and release kinetic constant (k) and its enhancement efficacy on drug skin absorption were investigated with in vitro skin retention study and in vitro skin permeation study, respectively. POCC released from the acidic-drug loading patches followed with the Higuchi release model and had short RD (8-16 h), resulting in its unsustainable enhancement efficiency for acidic drugs. However, POCC released from the basic-drug loading patches followed with zero-order model with long RD (12-24 h), inducing a sustainable and efficient enhancement efficiency for basic drugs. The lower variance of an innovative parameter permeation enhancement coefficient (CPE) represented the relatively sustainable and effective enhancement effect and was listed as followed: 0.20 (Zaltoprofen (ZPF)), 0.31 (Diclofenac (DCF)), 0.27 (Indomethacin (IMC)), 0.07 (Azasetron (AST)), 0.11 (Oxybutynin (OBN)) and 0.06 (Donepezil (DNP)). According to the results of FT-IR, MTDSC, 13C NMR spectra, molecular dynamics simulation, SAXS and Raman imaging, the Higuchi release model was caused by strong interaction between the acid drugs and pressure sensitive adhesive (PSA). This strong interaction induced faster diffusion speed of POCC from acidic-drug loading patches and make the swell degree of long periodicity phase (LPP) of stratum corneum (SC) lipids reached plateau early. The zero-order release model was because the weak interaction between basic drugs and PSA making most of POCC was still bound to PSA, which in turn lead to LPP swelled at a slow but sustainable process. In conclusion, zero-order release kinetic of POCC lead to sustainable and efficient penetration enhancement efficiency on basic drug, while the Higuchi release kinetic showed opposite effect for acidic drugs. A deep understanding of release kinetics of enhancer and its enhancement efficiency may drive the ideal selection of permeation enhancers and rational optimization of transdermal patches.

Abstract
Borneol, a traditional Chinese medicine, can enhance therapeutic efficacy by guiding the active ingredients to the target site. Reportedly, borneol improves the penetration capacity of the nasal, cornea, transdermal, intestinal, and blood-brain barriers. Although nanotechnology dramatically changed the face of oncology by targeting tumor sites, the efficiency of nanoparticles delivered to tumor sites is very low, with only 0.7% of the total particles delivered. Thus, based on the penetration ability and the inhibition drug efflux of borneol, it was expected to increase the targeting and detention efficacy of drugs into tumor sites in nanocarriers with borneol modification. Borneol modified nanocarriers used to improve drug-targeting has become a research focus in recent years, but few studies in this area, especially in the antitumor application. Hence, this review summarizes the recent development of nanocarriers with borneol modification. We focus on the updated works of improving therapeutic efficacy, reducing toxicity, inhibiting tumor metastasis, reversing multidrug resistance, and enhancing brain targeting to expand their application and provide a reference for further exploration of targeting drug delivery systems for solid tumor treatment.

Abstract
Efficient delivery of brain-targeted drugs is highly important for the success of therapies in neurodegenerative diseases. Borneol has several biological activities, such as anti-inflammatory and cell penetration enhancing effect, and can regulate processes in the neurovascular unit (NVU), such as protein toxic stress, autophagosome/lysosomal system, oxidative stress, programmed cell death and neuroinflammation. However, the influence of borneol on NVU in neurodegenerative diseases has not been fully explained. This study searched the keywords 'borneol', 'neurovascular unit', 'endothelial cell', 'astrocyte', 'neuron', 'blood-brain barrier', 'neurodegenerative diseases' and 'brain disease', in PubMed, BioMed Central, China National Knowledge Infrastructure (CNKI), and Bing search engines to explore the influence of borneol on NVU. In addition to the principle and mechanism of penetration of borneol in the brain, this study also showed its multiple regulation effects on NVU. Borneol was able to penetrate the blood-brain barrier (BBB), affecting the signal transmission between BBB and the microenvironment of the brain, down-regulating the expression of inflammatory and oxidative stress proteins in NVU, especially in microglia and astrocytes. In summary, borneol is a potential drug delivery agent for drugs against neurodegenerative diseases.

Abstract
Chemical penetration enhancer (CPE) is a preferred approach to improve drug permeability through the skin, due to its unique advantages of simple use and high compatibility. However, CPEs efficiency and safety problems frequently arise, which greatly restrains the further application in transdermal drug delivery systems (TDDS). To get access to the root of problems, the efficiency and safety of CPEs are reviewed especially from molecular perspectives, which include (1) the possible factors of CPEs low efficiency; (2) the possible contribution of CPEs in the evolution of safety problems such as skin irritation and allergic reaction; (3) the interactive relationship between CPEs efficiency and safety, as well as the bottlenecks of achieving their balance. More importantly, based on these, recent advances are summarized in improving efficiency or safety of CPEs, which offers a guidance of rationally selecting CPEs in future research.

Abstract
Incorporation of permeation enhancers is one of the most widely employed approaches for delivering drugs across biological membranes. Permeation enhancers aid in delivering drugs across various physiological barriers such as brain capillary endothelium, stratum corneum, corneal epithelium, and mucosal membranes that pose resistance to the entry of a majority of drugs. Borneol is a natural, plant-derived, lipophilic, volatile, bicyclic monoterpenoid belonging to the class of camphene. It has been used under the names "Bing Pian" or "Long Nao" in Traditional Chinese Medicine for more than 1000 years. Borneol has been incorporated predominantly as an adjuvant in the traditional Chinese formulations of centrally acting drugs to improve drug delivery to the brain. This background knowledge and anecdotal evidence have led to extensive research in establishing borneol as a permeation enhancer across the blood-brain barrier. Alteration in cell membrane lipid structures and modulation of multiple ATP binding cassette transporters as well as tight junction proteins are the major contributing factors to blood-brain barrier opening functions of borneol. Owing to these mechanisms of altering membrane properties, borneol has also shown promising potential to improve drug delivery across other physiological barriers as well. The current review focuses on the role of borneol as a permeation enhancer across the blood-brain barrier, mucosal barriers including nasal and gastrointestinal linings, transdermal, transcorneal, and blood optic nerve barrier.

Abstract
![]()
Transient
permeability enhancers (PEs), such as caprylate, caprate,
and salcaprozate sodium (SNAC), improve the bioavailability of poorly
permeable macromolecular drugs. However, the effects are variable
across individuals and classes of macromolecular drugs and biologics.
Here, we examined the influence of bile compositions on the ability
of membrane incorporation of three transient PEs—caprylate,
caprate, and SNAC—using coarse-grained molecular dynamics (CG-MD).
The availability of free PE monomers, which are important near the
absorption site, to become incorporated into the membrane was higher
in fasted-state fluids than that in fed-state fluids. The simulations
also showed that transmembrane perturbation, i.e.,
insertion of PEs into the membrane, is a key mechanism by which caprylate
and caprate increase permeability. In contrast, SNAC was mainly adsorbed
onto the membrane surface, indicating a different mode of action.
Membrane incorporation of caprylate and caprate was also influenced
by bile composition, with more incorporation into fasted- than fed-state
fluids. The simulations of transient PE interaction with membranes
were further evaluated using two experimental techniques: the quartz
crystal microbalance with dissipation technique and total internal
reflection fluorescence microscopy. The experimental results were
in good agreement with the computational simulations. Finally, the
kinetics of membrane insertion was studied with CG-MD. Variation in
micelle composition affected the insertion rates of caprate monomer
insertion and expulsion from the micelle surface. In conclusion, this
study suggests that the bile composition and the luminal composition
of the intestinal fluid are important factors contributing to the
interindividual variability in the absorption of macromolecular drugs
administered with transient PEs.

Abstract
Background Skin pharmacokinetics is an indispensable indication for studying the drug fate after administration of transdermal drug delivery systems (TDDS). However, the heterogeneity and complex skin structured with stratum corneum, viable epidermis, dermis, and subcutaneous tissue inevitably leads the drug diffusion coefficient (Kp) to vary depending on the skin depth, which seriously limits the development of TDDS pharmacokinetics in full thickness skin. Methods A multilayer geometry skin model was established and the Kp of drug in SC, viable epidermis, and dermis was obtained using the technologies of molecular dynamics simulation, in vitro permeation experiments, and in vivo microdialysis, respectively. Besides, finite element analysis (FEA) based on drug Kps in different skin layers was applied to simulate the paeonol nanoemulsion (PAE-NEs) percutaneous dynamic penetration process in two and three dimensions. In addition, PAE-NEs skin pharmacokinetics profile obtained by the simulation was verified by in vivo experiment. Results Coarse-grained modeling of molecular dynamic simulation was successfully established and the Kp of PAE in SC was 2.00×10−6 cm2/h. The Kp of PAE-NE in viable epidermis and in dermis detected using penetration test and microdialysis probe technology, was 1.58×10−5 cm2/h and 3.20×10−5 cm2/h, respectively. In addition, the results of verification indicated that PAE-NEs skin pharmacokinetics profile obtained by the simulation was consistent with that by in vivo experiment. Discussion This study demonstrated that the FEA combined with the established multilayer geometry skin model could accurately predict the skin pharmacokinetics of TDDS.

Abstract
Purpose Asiaticoside (ASI), a compound of triterpene pentacyclic saponins, has apparently therapeutic efficacy on human hypertrophic scar. However, the characteristics of large molecular weight, low water solubility and poor lipophilicity do not favor the diffusion through the stratum corneum (SC). Therefore, it is expected that the development of a transdermally delivered formulation may enhance the permeability ratio (Qn) of ASI for its clinical application. In this study, we designed asiaticoside-loaded nanoemulsions (ASI-NEs) and nanoemulsions-based gels (ASI-NBGs) and studied their mechanism for transdermal delivery. Methods The preparation of ASI-NEs was optimized by simplex lattice design (SLD). The ex vivo transdermal penetration and the in vivo pharmacokinetics studies were studied, respectively. The skin irritation of ASI-NEs and ASI-NBGs was measured on normal and damaged skin in rabbits, and the transcutaneous mechanisms of ASI-NEs and ASI-NBGs were determined by HE stained and confocal laser scanning microscopy (CLSM). Results The mean particle size of ASI-NEs was 132±5.84nm. The ex vivo skin permeation study verified that the Qn of the optimized ASI-NEs and ASI-NBGs was about 13.65 times and 5.05 times higher than that of the ordinary ASI-G group. In vivo, the pharmacokinetics studies showed that ASI-NEs and ASI-NBGs reached the peak value in the skin quickly and maintained stable release for a long time with high bioavailability. ASI-NEs and ASI-NBGs were proved to be safe when applied for topical skin usage, and they could play a therapeutic role through the skin mainly by acting on the microstructure of the SC and by means of the skin adnexal pathways. Conclusion ASI-NEs and ASI-NBGs were effectively developed to overcome the barrier properties of the skin and show high drug penetration through the transdermal route. In addition, we found that ASI-NEs and ASI-NBGs are safe when applied through transdermal delivery system.

Abstract
Transfersomes (TRS) can provide sustained drug delivery and themselves are biocompatible, biodegradable and nontoxic. Edge activators (EAs) are key factors for increasing the deformability of TRS, and this active deformation mechanism is of commercial interest, especially at the molecular level. Accordingly, in this paper, the deformability of pure dipalmitoyl phosphatidylcholine (DPPC) vesicles, TRS with sodium cholate as an EA, and DPPC vesicles containing pogostone (POG) were compared via umbrella sampling technology. The DPPC conformation and membrane fluidity of these three types of bilayer systems were evaluated, and the changes in the membrane properties of vesicles caused by EAs were studied. EAs could increase the deformability of TRS by decreasing the deformation energy barrier due to their amphiphilic structures, which was similar to those of DPPC molecules. The membrane properties also changed via treatment with EAs including altering the tail chain angle, disturbing the ordered tail chain arrangement and prompting lateral diffusion of DPPC molecules. In addition, the impact of EAs on DPPC bilayers was further demonstrated to be concentration dependent. An ideal concentration was identified for the lowest amount of EA that offered a gel-liquid-crystalline phase transition of DPPC bilayers. Importantly, POG, a lipophobic transdermal drug, can also affect the skin permeation behavior of vesicles but had weaker effects than EA.

Abstract
This Review illustrates the evaluation of permeability of lipid membranes from molecular dynamics (MD) simulation primarily using water and oxygen as examples. Membrane entrance, translocation, and exit of these simple permeants (one hydrophilic and one hydrophobic) can be simulated by conventional MD, and permeabilities can be evaluated directly by Fick's First Law, transition rates, and a global Bayesian analysis of the inhomogeneous solubility-diffusion model. The assorted results, many of which are applicable to simulations of nonbiological membranes, highlight the limitations of the homogeneous solubility diffusion model; support the utility of inhomogeneous solubility diffusion and compartmental models; underscore the need for comparison with experiment for both simple solvent systems (such as water/hexadecane) and well-characterized membranes; and demonstrate the need for microsecond simulations for even simple permeants like water and oxygen. Undulations, subdiffusion, fractional viscosity dependence, periodic boundary conditions, and recent developments in the field are also discussed. Last, while enhanced sampling methods and increasingly sophisticated treatments of diffusion add substantially to the repertoire of simulation-based approaches, they do not address directly the critical need for force fields with polarizability and multipoles, and constant pH methods.

Permeation-enhancing effects and mechanisms of borneol and menthol on ligustrazine: A multiscale study using in vitro and coarse-grained molecular dynamics simulation methods. Chem Biol Drug Des 2018; 92:1830-1837.

Abstract
Borneol (BO) and menthol (MEN) are two widely used natural permeation enhancers in the transdermal drug delivery system. In previous studies, their permeation enhancement effects and mechanisms of action on the hydrophobic drug osthole (logP = 3.8) and hydrophilic drug 5-fluorouracil (logP = -0.9) have been studied. In this study, ligustrazine (LTZ), whose logP is 1.3, was used as a model drug to provide a comprehensive understanding of the influence of its logP on the permeation-enhancing effects of BO and MEN. Both BO and MEN enhanced the permeation of LTZ through the skin stratum corneum, as determined using the modified Franz diffusion cell experiment. The enhancement mechanisms were illustrated by coarse-grained molecular dynamics simulations as follows: at low concentrations, the enhancing ratio of MEN was higher than that of BO because of the stronger perturbation effects of MEN on the lipid bilayer, making it looser and facilitating LTZ diffusion. However, at high concentrations, in addition to the diffusion mechanism, BO induced the formation of water channels to improve the permeation of LTZ; however, MEN had no significant effects through this mechanism. Their results were different from those found with osthole and 5-fluorouracil and have been discussed in this study.

A Molecular Interpretation on the Different Penetration Enhancement Effect of Borneol and Menthol towards 5-Fluorouracil. Int J Mol Sci 2017; 18:ijms18122747. [PMID: 29258240 PMCID: PMC5751346 DOI: 10.3390/ijms18122747] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2017] [Revised: 11/29/2017] [Accepted: 12/12/2017] [Indexed: 01/23/2023] Open
Abstract
Borneol and menthol are terpenes that are widely used as penetration enhancers in transdermal drug delivery. To explore their penetration-enhancement effects on hydrophilic drugs, 5-fluorouracil (5-FU) was selected as a model drug. An approach that combined in vitro permeation studies and coarse-grained molecular dynamics was used to investigate their penetration-enhancement effect on 5-FU. The results showed that although both borneol and menthol imparted penetration-enhancement effects on 5-FU, these differed in terms of their mechanism, which may account for the observed variations in penetration-enhancement effects. The main mechanism of action of menthol involves the disruption of the stratum corneum (SC) bilayer, whereas borneol involves multiple mechanisms, including the disruption of the SC bilayer, increasing the diffusion coefficient of 5-FU, and inducing the formation of transient pores. The findings of the present study improve our understanding of the molecular mechanism that is underlying 5-FU penetration-enhancement by borneol and menthol, which may be utilized in future investigations and applications.

Influence of Temperature on Transdermal Penetration Enhancing Mechanism of Borneol: A Multi-Scale Study. Int J Mol Sci 2017; 18:ijms18010195. [PMID: 28106833 PMCID: PMC5297826 DOI: 10.3390/ijms18010195] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2016] [Revised: 12/26/2016] [Accepted: 01/07/2017] [Indexed: 01/30/2023] Open
Abstract
The influence of temperature on the transdermal permeation enhancing mechanism of borneol (BO) was investigated using a multi-scale method, containing a coarse-grained molecular dynamic (CG-MD) simulation, an in vitro permeation experiment, and a transmission electron microscope (TEM) study. The results showed that BO has the potential to be used as a transdermal penetration enhancer to help osthole (OST) penetrate into the bilayer. With the increasing temperature, the stratum corneum (SC) becomes more flexible, proving to be synergistic with the permeation enhancement of BO, and the lag time (TLag) of BO and OST are shortened. However, when the temperature increased too much, with the effect of BO, the structure of SC was destroyed; for example, a water pore was formed and the micelle reversed. Though there were a number of drugs coming into the SC, the normal bilayer structure was absent. In addition, through comparing the simulation, in vitro experiment, and TEM study, we concluded that the computer simulation provided some visually detailed information, and the method plays an important role in related studies of permeation.
