Abstract
Phytochemicals, such as resveratrol, curcumin, and quercetin, have many benefits for health, but most of them have a low bioavailability due to their poor water solubility and stability, quick metabolism, and clearance, which restricts the scope of their potential applications. To overcome these issues, different types of nanoparticles (NPs), especially biocompatible and biodegradable NPs, have been developed. NPs can carry phytochemicals and increase their solubility, stability, target specificity, and oral bioavailability. However, NPs are prone to irreversible aggregation, which leads to NP instability and loss of functions. To remedy this shortcoming, stabilizers like polymers and surfactants are incorporated on NPs. Stabilizers not only increase the stability of NPs, but also improve their characteristics. The current review focused on discussing the state of the art in research on synthesizing phytochemical-based NPs and their commonly employed stabilizers. Furthermore, stabilizers in these NPs were also discussed in terms of their applications, effects, and underlying mechanisms. This review aimed to provide more references for developing stabilizers and NPs for future research.

Abstract
Herbal medicines have gained recognition among physicians and patients due to their lower adverse effects compared to modern medicines. They are extensively used to treat various diseases, including cancer, cardiovascular issues, chronic inflammation, microbial contamination, diabetes, obesity, and hepatic disorders, among others. Unfortunately, the clinical application of herbal medicines is limited by their low solubility and inadequate bioavailability. Utilizing herbal medicines in the form of nanocrystals (herbal medicine nanocrystals) has shown potential in enhancing solubility and bioavailability by reducing the particle size, increasing the specific surface area, and modifying the absorption mechanisms. Multiple studies have demonstrated that these nanocrystals significantly improve drug efficacy by reducing toxicity and increasing bioavailability. This review comprehensively examines therapeutic approaches based on herbal medicine nanocrystals. It covers the preparation principles, key factors influencing nucleation and polymorphism control, applications, and limitations. The review underscores the importance of optimizing delivery systems for successful herbal medicine nanocrystal therapeutics. Furthermore, it discusses the main challenges and opportunities in developing herbal medicine nanocrystals for the purpose of treating conditions such as cancer, inflammatory diseases, cardiovascular disorders, mental and nervous diseases, and antimicrobial infections. In conclusion, we have deliberated regarding the hurdles and forthcoming outlook in the realm of nanotoxicity, in vivo kinetics, herbal ingredients as stabilizers of nanocrystals, and the potential for surmounting drug resistance through the utilization of nanocrystalline formulations in herbal medicine. We anticipate that this review will offer innovative insights into the development of herbal medicine nanocrystals as a promising and novel therapeutic strategy.

Abstract
Drug nanocrystals, which are comprised of active pharmaceutical ingredients and only a small amount of essential stabilizers, have the ability to improve the solubility, dissolution and bioavailability of poorly water-soluble drugs; in turn, drug nanocrystal technology can be utilized to develop novel formulations of chemotherapeutic drugs. Compared with passive targeting strategy, active tumor-targeted drug delivery, typically enabled by specific targeting ligands or molecules modified onto the surface of nanomedicines, circumvents the weak and heterogeneous enhanced permeability and retention (EPR) effect in human tumors and overcomes the disadvantages of nonspecific drug distribution, high administration dosage and undesired side effects, thereby contributing to improving the efficacy and safety of conventional nanomedicines for chemotherapy. Continuous efforts have been made in the development of active tumor-targeted drug nanocrystals delivery systems in recent years, most of which are encouraging and also enlightening for further investigation and clinical translation.

Abstract
The objective of this study was to develop novel herpetrione (HPE) nanosuspensions stabilized by glycyrrhizin (HPE NSs/GL) for enhancing bioavailability and hepatoprotective effect of HPE. HPE NSs/GL were prepared by wet media milling method and then systemically evaluated by particle size analysis, scanning electronic microscopy (SEM), X-ray powder diffraction (XRPD), dissolution test, pharmacokinetics, and hepatoprotective effect. HPE-NSs stabilized by poloxamer 407 (HPE NSs/P407) were also prepared and used as a reference for comparison. HPE NSs/GL and HPE-NSs/P407 with similar particle sizes around 450 nm and PDI less than 0.2 were successfully prepared and both of them appeared to be spherical under SEM. The XRPD results demonstrated that HPE in both HPE NSs/GL and HPE NSs/P407 was presented in the amorphous state and the addition of GL or P407 and the milling process didn't alter the physical state of HPE. The dissolution and pharmacokinetic studies demonstrated that HPE NSs/GL exhibited significant enhancement in drug dissolution (72.44% within 24 h) and AUC0-t (24.91 ± 3.3 mg/L·h) as compared to HPE coarse suspensions (HPE CS, 34.19% & 13.07 ± 1.02 mg/L·h), but was similar with those of HPE NSs/P407 (80.06% & 26.75 ± 4.06 mg/L•h). Moreover, HPE NSs/GL exhibited significantly better hepatoprotective effect as compared to HPE CS and HPE NSs/P407 as indicated by the lowering of the elevated serum ALT and AST levels and the improvement of the hepatic morphology and architecture, which might be attributed to the improved bioavailability of HPE, and synergistic hepatoprotective effect of GL via alleviating inflammation evidenced by the significant decreased hepatic levels of inflammatory cytokines IL-1β, IL-6 and TNF-α. It could be concluded that GL might be an effective stabilizer for preparing HPE NSs, and HPE NSs/GL is a potential formulation strategy for improving oral bioavailability and hepatoprotective effect of HPE.

Abstract
Andrographis paniculata (Burm. f.) Wall. ex Nees, a renowned herb medicine in China, is broadly utilized in traditional Chinese medicine (TCM) for the treatment of cold and fever, sore throat, sore tongue, snake bite with its excellent functions of clearing heat and toxin, cooling blood and detumescence from times immemorial. Modern pharmacological research corroborates that andrographolide, the major ingredient in this traditional herb, is the fundamental material basis for its efficacy. As the main component of Andrographis paniculata (Burm. f.) Wall. ex Nees, andrographolide reveals numerous therapeutic actions, such as antiinflammatory, antioxidant, anticancer, antimicrobial, antihyperglycemic and so on. However, there are scarcely systematic summaries on the specific mechanism of disease treatment and pharmacokinetics. Moreover, it is also found that it possesses easily ignored security issues in clinical application, such as nephrotoxicity and reproductive toxicity. Thereby it should be kept a lookout over in clinical. Besides, the relationship between the efficacy and security issues of andrographolide should be investigated and evaluated scientifically. In this review, special emphasis is given to andrographolide, a multifunctional natural terpenoids, including its pharmacology, pharmacokinetics, toxicity and pharmaceutical researches. A brief overview of its clinical trials is also presented. This review intends to systematically and comprehensively summarize the current researches of andrographolide, which is of great significance for the development of andrographolide clinical products. Noteworthy, those un-cracked issues such as specific pharmacological mechanisms, security issues, as well as the bottleneck in clinical transformation, which detailed exploration and excavation are still not to be ignored before achieving integration into clinical practice. In addition, given that current extensive clinical data do not have sufficient rigor and documented details, more high-quality investigations in this field are needed to validate the efficacy and/or safety of many herbal products.

Abstract
Lentinan is a natural β-glucan with various bioactivities and is combined with chemotherapy drugs for cancer treatment. Regorafenib is an oral multi-kinase inhibitor approved by FDA for treatment of metastatic colorectal cancer, advanced hepatocellular carcinoma, and metastatic gastrointestinal stromal tumors. Regorafenib has poor water solubility and multiple toxicities. We report drug-drug nanosuspensions of regorafenib and lentinan. Results of dynamic light scattering and scanning electron microscopy showed that the mean particle size of the regorafenib-lentinan nanosuspensions was approximately 200 nm and was uniformly distributed. Transmission electron microscopy findings indicated that lentinan stabilized the nanosuspensions by steric manner. Hydrogen bonds and hydrophobic interactions were found between regorafenib and lentinan by molecular dynamics simulation. The results of cytotoxicity assay and pharmacokinetics study in rats showed that the regorafenib-lentinan nanosuspensions reduced the toxicity and enhanced the in vitro anticancer activity and oral bioavailability of regorafenib. Lentinan as a natural stabilizer has the potential using for drug nanosuspensions. Drug-drug nanosuspensions are a new form of combination therapies that can reduce the number of drugs taken by patients and improve their compliance.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Synthetic drugs used for cancer treatment have side effects that may be immunosupressive, can cause liver, kidney and cardiac toxicity, and infertility and ovarian failure, among others. Thus, herbal drugs could be used in the cancer treatment as an adjuvant therapy. Andrographis paniculata (Burm.f.) Nees (AP) is one of the traditional herbs used in different alternative medicinal systems such as Ayurveda, Unani, Chinese, Malayi, Siddha, etc. for the treatment of various disorders and diseases including cancer. AIM OF THE STUDY The aim of writing this review is to highlight the medicinal importance of AP and its main phytoconstituent andrographolide (AG). The main emphasis was given on the anticancer activity of AG, its proposed mechanisms of action, novel approaches used to improve its biopharmaceutical properties with the perspective of evidence-based research, and its development as an adjuvant therapy for cancer treatment in future. MATERIALS AND METHODS Literature survey was conducted and research papers were retrieved from different databases such as Pubmed, Google Scholar, ACS, Wiley online library, ScienceDirect, Springer, and Scopus during 1970-2020. Research articles, review articles, and short communications, etc. were used for this purpose. The papers were selected on the basis of exclusion and inclusion criteria. RESULTS Different anticancer mechanisms of AG have been reportedly proven such as cell cycle arrest, apoptosis, NF-κβ inhibition, antiangiogenesis, cytokine inhibition, etc. whereas its pharmacokinetic properties showed its highly protein bound nature, Cyt P400 (CYP) inhibition, low aqueous solubility, poor oral bioavailability, etc. Different novel formulations of AG have been investigated to increase its bioavailability for better efficacy. CONCLUSION This review can provide knowledge about the potential applicability of AP or AG as an adjuvant therapy in cancer treatment. Further research is needed before making any conclusion about the efficacy in humans as an adjuvant therapy in cancer.

Abstract
The objective of this study is to use a carbohydrate polymer deacetylated gellan gum (DGG) as matrix to design nanocrystals based intranasal in situ gel (IG) for nose-to -brain delivery of drug. The harmine nanocrystals (HAR-NC) as model drug were prepared by coupling homogenization and spray-drying technology. The HAR-NC was redispersed in the (DGG) solutions and formed the ionic-triggered harmine nanocrystals based in situ gel (HAR-NC-IG). The crystal state of HAR remained unchanged during the homogenization and spray-drying. And the HAR-NC-IG with 0.5% DGG exhibited excellent in situ-gelation ability, water retention property and in vitro release behavior. The bioavailability in brain of intranasal HAR-NC-IG were 25-fold higher than that of oral HAR-NC, which could be attributed to nanosizing effect of HAR-NC and bioadhesive property of DGG triggered by nasal fluid. And the HAR-NC-IG could significantly inhibit the expression of acetylcholinesterase (AchE) and increase the content of acetylcholin (ACh) in brain compared with those of reference formulations (p < 0.01). The DGG based nanocrystals-in situ gel was a promising carrier for nose-to-brain delivery of poorly soluble drug, which could prolong the residence time and improve the bioavailability of poorly soluble drugs in brain.

Abstract
Tea saponins (TS), a novel multifunctional stabilizer, were explored to stabilize the nanosuspensions. The purpose of this study was to investigate the effect of TS on the stability and redispersibility of nanosuspensions. In present work, hesperidin (HDN), a poorly soluble drug, was used as a model drug. HDN nanosuspensions (HDN-NS) with particle size of 250-270 nm were prepared by high-speed shearing and high-pressure homogenization. The zeta potential of HDN-NS was -23.16 ± 1.12 mV. Compared with traditional stabilizers, TS were superior in stabilization efficiency at low concentrations. Nanosuspensions freeze-dried powder using TS and lactose as cryoprotectants had good redispersibility, and the average particle size was 266.5 ± 9.0 nm after reconstitution. TS and lactose can effectively prevent the irreversible agglomeration of HDN-NS during freeze-drying. The dissolution was enhanced owing to particle size reduction. Transmission electron microscopy (TEM) and Scanning electron microscopy (SEM) results showed that HDN nanocrystals were irregularly lumpy. The chemical structure and crystal state of HDN had not significantly changed during production. In conclusion, TS have the potential to stabilize and disperse nanosuspensions and provide a promising strategy for the development of poorly soluble drugs.

Novel breviscapine nanocrystals modified by panax notoginseng saponins for enhancing bioavailability and synergistic anti-platelet aggregation effect. Colloids Surf B Biointerfaces 2018; 175:333-342. [PMID: 30554011 DOI: 10.1016/j.colsurfb.2018.11.067] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2018] [Revised: 11/07/2018] [Accepted: 11/26/2018] [Indexed: 12/16/2022]
Abstract
Breviscapine (BVP) is a flavonoid compound with strong neuroprotective and anti-platelet aggregation effect. The objective of this study is to design novel BVP nanocrystals modified by natural panax notoginseng saponins (PNS) for enhancing dissolution and anti-platelet aggregation effect of BVP. BVP nanocrystals modified by PNS (BVP-NC/PNS) were firstly prepared by coupling homogenization technology and freeze-drying technology, and BVP nanocrystals modified by RH40 (BVP-NC/RH40) as reference for comparison. The morphology, crystals characterization, dissolution behavior and anti-platelet aggregation effect of BVP-NC/PNS was systemically evaluated. The results demonstrated that the PNS could effectively maintain stability of BVP-NC at suspensions state dependent of its surface activity and the electrostatic repulsion effect. Combination of PNS and trehalose could prevent the aggregation of BVP-NC/PNS during freeze-drying. The PXRD and DSC results demonstrated that the BVP crystal state in BVP-NC/PNS was not changed owing to PNS modification and homogenization treatment. And the freeze-dried BVP-NC could easily recover back to BVP-NS and significantly improve the dissolution of BVP. The AUC(0-∞) of the BVP-NC/PNS was 4.54 times as high as that of the coarse BVP, but not significantly different compared to that of BVP-NC/RH40 (p < 0.05). The anti-platelet aggregation results demonstrated that, BVP-NC/PNS group showed more effective inhibition on PAF-induced platelet aggregation compared with corresponding control groups, which might attribute to the enhanced bioavailability of BVP and synergistic effect of PNS with BVP. In conclusion, PNS could be used as an alternative stabilizer for preparation of BVP-NC, and BVP-NC modified by PNS is a promising formulation strategy for enhancing oral bioavailability and anti-platelet aggregation of BVP.

Bioavailability Enhancement of Poorly Water-Soluble Drugs via Nanocomposites: Formulation⁻Processing Aspects and Challenges. Pharmaceutics 2018; 10:pharmaceutics10030086. [PMID: 29986543 PMCID: PMC6160929 DOI: 10.3390/pharmaceutics10030086] [Citation(s) in RCA: 100] [Impact Index Per Article: 16.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2018] [Revised: 07/01/2018] [Accepted: 07/01/2018] [Indexed: 11/16/2022] Open
Abstract
Drug nanoparticles embedded in a dispersant matrix as a secondary phase, i.e., drug-laden nanocomposites, offer a versatile delivery platform for enhancing the dissolution rate and bioavailability of poorly water-soluble drugs. Drug nanoparticles are prepared by top-down, bottom-up, or combinative approaches in the form of nanosuspensions, which are subsequently dried to prepare drug-laden nanocomposites. In this comprehensive review paper, the term “nanocomposites” is used in a broad context to cover drug nanoparticle-laden intermediate products in the form of powders, cakes, and extrudates, which can be incorporated into final oral solid dosages via standard pharmaceutical unit operations, as well as drug nanoparticle-laden strip films. The objective of this paper is to review studies from 2012⁻2017 in the field of drug-laden nanocomposites. After a brief overview of the various approaches used for preparing drug nanoparticles, the review covers drying processes and dispersant formulations used for the production of drug-laden nanocomposites, as well as various characterization methods including quiescent and agitated redispersion tests. Traditional dispersants such as soluble polymers, surfactants, other water-soluble dispersants, and water-insoluble dispersants, as well as novel dispersants such as wet-milled superdisintegrants, are covered. They exhibit various functionalities such as drug nanoparticle stabilization, mitigation of aggregation, formation of nanocomposite matrix⁻film, wettability enhancement, and matrix erosion/disintegration. Major challenges such as nanoparticle aggregation and poor redispersibility that cause inferior dissolution performance of the drug-laden nanocomposites are highlighted. Literature data are analyzed in terms of usage frequency of various drying processes and dispersant classes. We provide some engineering considerations in comparing drying processes, which could account for some of the diverging trends in academia vs. industrial practice. Overall, this review provides rationale and guidance for drying process selection and robust nanocomposite formulation development, with insights into the roles of various classes of dispersants.
