Abstract
PURPOSE Gallic acid (GA) is a polyphenolic compound with proven efficacy against hepatic fibrosis in experimental animals. However, it suffers from poor bioavailability and rapid clearance that hinders its clinical investigation. Accordingly, we designed and optimized reverse micelle-loaded lipid nanocapsules (RMLNC) using Box-Behnken design that can deliver GA directly into activated-hepatic stellate cells (aHSCs) aiming to suppress hepatic fibrosis progression. METHODS GA-RMLNC was prepared using soft energy, solvent free phase inversion temperature method. Effects of formulation variables on particle size, zeta potential, entrapment efficiency (EE%) and GA release were studied. In-vivo biodistribution of GA-RMLNC in rats and in-vitro activities on aHSCs were also explored. RESULTS Nano-sized GA-RMLNCs (30.35 ± 2.34 nm) were formulated with high GA-EE% (63.95 ± 2.98% w/w) and physical stability (9 months). The formulated system showed burst GA release in the first 2 h followed by sustained release profile. In-vivo biodistribution imaging revealed that RMLNC-loaded with rhodamine-B accumulated mainly in rats' livers. Relative to GA; GA-RMLNC displayed higher anti-proliferative activities, effective internalization into aHSCs, marked down-regulation in pro-fibrogenic biomarkers' expressions and elevated HSCs' apoptosis. CONCLUSIONS These findings emphasize the promising application of RMLNC as a delivery system in hepatic fibrosis treatment, where successful delivery of GA into aHSCs was ensured via increased cellular uptake and antifibrotic activities.

Abstract
Acanthamoeba, a genus that contains at least 24 species of free-living protozoa, is ubiquitous in nature. Successful treatment of Acanthamoeba infections is always very difficult and not always effective. More effective drugs must be developed, and medicinal plants may have a pivotal part in the future of drug discovery. Our research focused on investigating the in vitro anti- acanthamoebic potential of Leea indica and its constituent gallic acid in different concentrations. Water and butanol fractions exhibited significant amoebicidal activity against trophozoites and cysts. Gallic acid (100 µg/mL) revealed 83% inhibition of trophozoites and 69% inhibition of cysts. The butanol fraction induced apoptosis in trophozoites, which was observed using tunnel assay. The cytotoxicity of the fractions and gallic acid was investigated against MRC-5 and no adverse effects were observed. Gallic acid was successfully loaded within poly (D,L-lactide-co-glycolide) (PLGA) nanoparticles with 82.86% encapsulation efficiency, while gallic acid showed 98.24% in vitro release at 48 hours. Moreover, the gallic acid encapsulated in the PLGA nanoparticles exhibited 90% inhibition against trophozoites. In addition, gallic acid encapsulated nanoparticles showed reduced cytotoxicity towards MRC-5 compared to gallic acid, which evidenced that natural product nanoencapsulation in polymeric nanoparticles could play an important role in the delivery of natural products.

Abstract
Diabetes mellitus is a life-threatening metabolic syndrome. Over the past few decades, the incidence of diabetes has climbed exponentially. Several therapeutic approaches have been undertaken, but the occurrence and risk still remain unabated. Several plant-derived small molecules have been proposed to be effective against diabetes and associated vascular complications via acting on several therapeutic targets. In addition, the biocompatibility of these phytochemicals increasingly enhances the interest of exploiting them as therapeutic negotiators. However, poor pharmacokinetic and biopharmaceutical attributes of these phytochemicals largely restrict their clinical usefulness as therapeutic agents. Several pharmaceutical attempts have been undertaken to enhance their compliance and therapeutic efficacy. In this regard, the application of nanotechnology has been proven to be the best approach to improve the compliance and clinical efficacy by overturning the pharmacokinetic and biopharmaceutical obstacles associated with the plant-derived antidiabetic agents. This review gives a comprehensive and up-to-date overview of the nanoformulations of phytochemicals in the management of diabetes and associated complications. The effects of nanosizing on pharmacokinetic, biopharmaceutical and therapeutic profiles of plant-derived small molecules, such as curcumin, resveratrol, naringenin, quercetin, apigenin, baicalin, luteolin, rosmarinic acid, berberine, gymnemic acid, emodin, scutellarin, catechins, thymoquinone, ferulic acid, stevioside, and others have been discussed comprehensively in this review.

Abstract
Antioxidants interact with free radicals, terminating the adverse chain reactions and converting them to harmless products. Antioxidants thus minimize the oxidative stress and play a crucial role in the treatment of free radicals-induced diseases. However, the effectiveness of natural and/or synthetic antioxidants is limited due to their poor absorption, difficulties to cross the cell membranes, and degradation during delivery, hence contributing to their limited bioavailability. To address these issues, antioxidants covalently linked with nanoparticles, entrapped in nanogel, hollow particles, or encapsulated into nanoparticles of diverse origin have been used to provide better stability, gradual and sustained release, biocompatibility, and targeted delivery of the antioxidants with superior antioxidant profiles. This review aims to critically evaluate the recent scientific evaluations of nanoparticles as the antioxidant delivery vehicles, as well as their contribution in efficient and enhanced antioxidant activities.

Abstract
Vulvovaginal candidiasis (VVC) is a widely spread fungal infection that causes itching, pain and inflammation at the vaginal site. Although common, currently available treatment suffers from limited efficacy and high recurrence. In addition, the growing problem of resistance to azole drugs used in current treatments emphasizes the need for superior treatment options. Antimicrobial polyphenols are an attractive approach offering multitargeting therapy. We aimed to develop novel liposomes for simultaneous delivery of two polyphenols (quercetin, Q, and gallic acid, GA) that, when released within the vaginal cavity, act in synergy to eradicate infection while alleviating the symptoms of VVC. Q was selected for its anti-itching and anti-inflammatory properties, while GA for its reported activity against Candida. Novel liposomes containing only Q (LP-Q), only GA (LP-GA) or both polyphenols (LP-Q+GA) were in the size range around 200 nm. Q was efficiently entrapped in both LP-Q and in LP-Q+GA (85%) while the entrapment of GA was higher in LP-Q+GA (30%) than in LP-GA (25%). Liposomes, especially LP-Q+GA, promoted sustained release of both polyphenols. Q and GA acted in synergy, increasing the antioxidant activities of a single polyphenol. Polyphenol-liposomes were not cytotoxic and displayed stronger anti-inflammatory effects than free polyphenols. Finally, LP-GA and LP-Q+GA considerably reduced C. albicans growth.

Abstract
Mangiferin is an important xanthone compound presenting various biological activities. The objective of this study was to develop, characterize physicochemical properties, and evaluate the anti-topoisomerase activity of poly(lactic-co-glycolic acid) (PLGA) nanoparticles containing mangiferin. The nanoparticles were developed by the emulsion solvent evaporation method and the optimal formulation was obtained with a response surface methodology (RSM); this formulation showed a mean size of 176.7 ± 1.021 nm with a 0.153 polydispersibility index (PDI) value, and mangiferin encapsulation efficiency was about 55%. The optimal conditions (6000 rpm, 10 min, and 300 μg of mangiferin) obtained 77% and the highest entrapment efficiency (97%). The in vitro release profile demonstrated a gradual release of mangiferin from 15 to 180 min in acidic conditions (pH 1.5). The fingerprint showed a modification in the maximum absorption wavelength of both the polymer and the mangiferin. Results of anti-toposiomerase assay showed that the optimal formulation (MG4, 25 µg/mL) had antiproliferative activity. High concentrations (2500 µg/mL) of MG4 showed non-in vitro cytotoxic effect on BEAS 2B and HEPG2. Finally, this study showed an encapsulation process with in vitro gastric digestion resistance (1.5 h) and without interfering with the metabolism of healthy cells and their biological activity.

Abstract
Objective: In this study, we investigated the in vivo antitumor activity and pharmacokinetic characteristics of encapsulated GA-NC (gallic acid nanocomposite) in normal and hepatocellular carcinoma (HCC)-induced rats. Methods: Rats were distributed into 4 groups; negative control, HCC, gallic acid (GA), and GA-NC. Serum levels of alpha-fetoprotein (AFP), endoglin (ENG), heat shock protein-70 (HSP-70), pro-caspase 3, lipocalin-2 (LCN-2) and β-cell leukemia/lymphoma 2 (Bcl-2) were assayed by ELISA. The pharmacokinetic parameters for GA or GA-NC were determined by means of non-compartmental approach based on the serum– concentration profiles of free GA and GA-NC after oral administration. Also, histological procedures were used for examination of liver tissue sections. Results: Anaplastic changes in liver tissues were observed in untreated HCC group, as well as a significant increase in the serum AFP level. In addition, significant elevation in the serum ENG level as an angiogenic marker and the serum levels of the apoptotic mediators; HSP-70, Bcl-2 and pro-caspase 3 beside significant amplification in the serum inflammatory modulator, LCN-2 were recorded. Treatment with free GA or GA-NC markedly recovered the anaplastic changes in the rat liver tissues. In addition, they restored serum levels of AFP, ENG, HSP-70, Bcl-2, pro-caspase-3, and LCN-2. Pharmacokinetic analysis revealed that GA–NC displayed a characteristic sustained release profile with 4-fold increase in bioavailability in normal and HCC-induced rats. Conclusions: The results of this study suggest that encapsulation of GA into PLGA-CS-PEG enhances its oral bioavailability and anti-cancer activity. GA-NC may be a new therapeutic candidate for the mitigation of hepatocarcinogenesis.

Abstract
Chitosan, possessing excellent properties, has been drawing broad attention. For the further utilization of chitosan, chemical modification is performed in improving its water solubility and the bioactivities. In the current study, four N,N,N-trimethyl chitosan salts, including N,N,N-trimethyl chitosan citrate (TMCSCi), N,N,N-trimethyl chitosan acetylsalicylate (TMCSAc), N,N,N-trimethyl chitosan ascorbate (TMCSAs), and N,N,N-trimethyl chitosan gallate (TMCSGa), were prepared via N,N,N-trimethyl chitosan iodide (TMCSI). The as-prepared products were characterized by FT-IR and 1H NMR. Meanwhile, the degrees of substitution were calculated by elemental analysis results. Furthermore, scavenging activities (against DPPH radicals and superoxide radicals) test and reducing power test were selected to evaluate the antioxidant property of N,N,N-trimethyl chitosan salts in vitro. The results indicated that TMCSAs and TMCSGa displayed excellent activity, probably due to the enhancement of ascorbate and gallate in antioxidant activity. However, because of the weak antioxidant property of citrate and acetylsalicylate, the activity was lower for TMCSCi and TMCSAc. For example, in the DPPH radicals scavenging assay, the scavenging rates of chitosan, TMCSI, TMCSCi, TMCSAc, TMCSAs, and TMCSGa were 25.22, 84.11, 6.90, 2.70, 94.92, and 96.75% at 0.4 mg/mL, respectively. Generally, TMCSAs and TMCSGa could be regarded as a potential source of antioxidants.

Abstract
Gallic acid (GA) is a naturally occurring compound with valuable antioxidant activity. Its oral bioavailability is limited by its high metabolism and rapid clearance. In this paper, GA was conjugated with two different materials, phosphatidylcholine (PC) and polyamidoamine (PAMAM) dendrimer. The prepared conjugates were characterized by FTIR, DSC, and SEM. Also, they were tested for drug content and in vitro drug release. It was found that GA conjugation with both materials have significantly prolonged its release up to 12 h. In vivo hepatoprotective activity of free and conjugated GA was studied in rats after carbon tetrachloride (CCl4)-induced oxidative damage in rat liver through measurement of different liver marker enzymes (aspartate aminotransferase (AST), alanine aminotransferase (ALT)), in addition to the total protein and albumin level in rat serum. Also, histopathological examination of liver cell of all rat groups was done. Results showed that both prepared conjugates have significantly reduced the hepatic marker enzymes accompanied by normalizing total protein and albumin levels in rat serum and with respect to CCl4-induced group (p < .05). Histopathological examination showed that pretreatment of rats with GA-PC or GA-PAMAM before CCL4 could reduce the induced cellular histopathological changes. It appears that conjugation of GA could enhance its bioavailability and increase its hepatoprotective effect.

Martins LG, Khalil NM, Mainardes RM. Application of a validated HPLC-PDA method for the determination of melatonin content and its release from poly(lactic acid) nanoparticles. J Pharm Anal 2017; 7:388-393. [PMID: 29404064 PMCID: PMC5790749 DOI: 10.1016/j.jpha.2017.05.007] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2016] [Revised: 04/06/2017] [Accepted: 05/19/2017] [Indexed: 01/16/2023] Open
Abstract
Melatonin is a natural hormone and with the advancement of age its production declines and thereby may result in some neurological disorders. Exogenous administration of melatonin has been suggested as a neuroprotective agent. Due to its low oral bioavailability, the loading of melatonin in polymeric nanoparticles could be an important tool to effectively use exogenous melatonin. The quantification of the incorporated drug within polymeric nanoparticles is an important step in nanoparticles characterization. An analytical method using high performance liquid chromatography equipped with photodiode array detector (HPLC-PDA) was developed and validated for melatonin determination in poly (lactic acid) nanoparticles obtained by a single emulsion-solvent evaporation technique. The melatonin in vitro release profile also was determined by the HPLC method. Mobile phase consisted of acetonitrile: water (65:35, v/v) pumped at a flow rate of 0.9 mL/min, in the isocratic mode and PDA detector was set at 220 nm. The method was validated in terms of the selectivity, linearity, precision, accuracy, robustness, limits of detection and quantification. Analytical curve was linear over the concentration range of 10–100 μg/mL, and limits of detection and quantification were 25.9 ng/mL and 78.7 ng/mL, respectively. The mean recovery for melatonin was 100.47% (RSD = 1.25%, n = 9). In the intra- and inter-assay, the coefficient of variation was less than 2%. Robustness was proved performing changes in mobile phase, column temperature and flow rate. The method was suitable for the determination of melatonin encapsulation efficiency in poly(lactic acid) nanoparticles and for the evaluation of melatonin in vitro release profile.

Abstract
In this work is reported a novel and promising approach for the preparation of C-glycosylflavonoid enriched fraction of Cecropia glaziovii (EFF-Cg) loaded PLGA nanoparticles (NP) with antiherpes properties. The purpose of this study was to evaluate and to compare the effect of two nonionic surfactants (poloxamer 188 (PLU) and polyvinyl alcohol (PVA)), and also an emulsion stabilized by solid particles of cellulose nanocrystal (CNC) in place of surfactants. The characterization of these nanoparticles was in terms of size, polydispersity index, zeta potential, morphology, thermogravimetric analysis (TGA), loading capacity and percent yield. Since TGA analysis revealed thermo stability especially for NP-PLU, this formulation was selected for the evaluation of drug release profile, cytotoxicity and antiherpes activity. The drug delivery profile demonstrated a sustained release through the polymer structure and a significant reduction of the polymer molecular weight at 21-day period. The cytotoxicity of these nanoparticles was determined on Vero cells, and the selected formulation did not exhibit cytotoxicity even at the highest tested concentration. The results demonstrated a potential antiherpetic effect of the EFF-Cg loaded NP at 48h of testing. In summary, EFF-Cg loaded NP exhibited a promising system for the effective drug delivery in the treatment of herpes infections.

Enhanced photostability, radical scavenging and antitumor activity of indole-3-carbinol-loaded rose hip oil nanocapsules. MATERIALS SCIENCE & ENGINEERING.

Abstract
This study aimed to develop poly(ε-caprolactone) nanocapsules loaded with indole-3-cabinol (I3C) using rose hip oil (RHO) or medium chain triglycerides (MCT) as oil core. In vitro radical scavenging activity (DPPH method), hemolysis, and antitumor effects on breast (MCF-7) and glioma (C6) cells were conducted. Preformulation evaluations revealed that RHO is suitable to prepare the nanocapsules considering the log P determination and dissolution/swelling experiments of polymer films. The nanocapsules were prepared and presented adequate physicochemical characteristics as mean size around 250nm, polydispersity index values <0.2, zeta potential negative values and I3C encapsulation efficiency around 42%, without any influence of the oil core (RHO or MCT) on these parameters. However, the photodegradation study demonstrated that RHO nanocapsules showed less degree of I3C degradation in comparison to MCT nanocapsules. The in vitro release profile showed that both nanocapsule suspensions demonstrated an initial burst effect followed by a prolonged I3C release. In addition, the formulations were considered hemocompatibles at 10μg/mL and showed an enhanced radical scavenging activity in comparison to free I3C. Moreover, nanocapsules prepared with RHO increased about two times the antitumor effect of I3C on MCF-7 and C6 cells without significant reduction of astrocyte cell viability. In conclusion, nanocapsule formulations developed in this study might be considered promising for cancer treatment.

Increased cellular uptake of lauryl gallate loaded in superparamagnetic poly(methyl methacrylate) nanoparticles due to surface modification with folic acid. JOURNAL OF MATERIALS SCIENCE. MATERIALS IN MEDICINE 2016; 27:185. [PMID: 27787810 DOI: 10.1007/s10856-016-5796-0] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/20/2016] [Accepted: 10/13/2016] [Indexed: 06/06/2023]
Abstract
Lauryl gallate loaded in superparamagnetic poly(methyl methacrylate) nanoparticles surface modified with folic acid were synthesized by miniemulsion polymerization in just one step. In vitro biocompatibility and cytotoxicity assays on L929 (murine fibroblast), human red blood, and HeLa (uterine colon cancer) cells were performed. The effect of folic acid at the nanoparticles surface was evaluated through cellular uptake assays in HeLa cells. Results showed that the presence of folic acid did not affect substantially the polymer particle size (~120 nm), the superparamagnetic behavior, the encapsulation efficiency of lauryl gallate (~87 %), the Zeta potential (~38 mV) of the polymeric nanoparticles or the release profile of lauryl gallate. The release profile of lauryl gallate from superparamagnetic poly(methyl methacrylate) nanoparticles presented an initial burst effect (0-1 h) followed by a slow and sustained release, indicating a biphasic release system. Lauryl gallate loaded in superparamagnetic poly(methyl methacrylate) nanoparticles with folic acid did not present cytotoxicity effects on L929 and human red blood cells. However, free lauryl gallate presented significant cytotoxic effects on L929 and human red blood cells at all tested concentrations. The presence of folic acid increased the cytotoxicity of lauryl gallate loaded in nanoparticles on HeLa cells due to a higher cellular uptake when HeLa cells were incubated at 37 °C. On the other hand, when the nanoparticles were incubated at low temperature (4 °C) cellular uptake was not observed, suggesting that the uptake occurred by folate receptor mediated energy-dependent endocytosis. Based on presented results our work suggests that this carrier system can be an excellent alternative in targeted drug delivery by folate receptor.

Abstract
Poly(lactic acid) (PLA) nanoparticles containing vanillin were prepared using an emulsion-solvent evaporation technique and were characterized and assessed for their in vitro antioxidant potential. Physicochemical properties of the nanoparticles were characterized by size, polydispersity index, zeta potential, encapsulation efficiency and stability. Solid state and thermal properties were assessed using X-ray diffraction and differential scanning calorimetry, while in vitro drug release profile was also evaluated. Results showed PLA nanoparticles having a characteristic amorphous structure, sizes in the range of 240 nm with high homogeneity in size distribution, zeta potential of -22 mV and vanillin encapsulation efficiency of 41%. In vitro release study showed a slow and sustained release of vanillin governed by diffusion. Nanoparticles were stable over a period of three months. Antioxidant ability of the vanillin-loaded PLA nanoparticles in scavenging the radical 2,2-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) was inferior to free vanillin and due to its prolonged release showed a profile that was both time and concentration dependent, while free vanillin showed concentration-dependent activity. The study concluded that PLA nanoparticles are potential carriers for vanillin delivery.
