Abstract
Melanoma is a highly lethal type of cancer that has had an increase in incidence in the last decades. Nevertheless, current therapies lack effectiveness and have highly disabling side effects, which calls for new therapeutic strategies. Norcantharidin (NCTD) is an acid derivative with potential antitumor activity isolated from natural blister beetles. However, its solubility limitations restrict its use. To address this issue, we developed an oil-in-water nanoemulsion using commonly available cosmetic ingredients, which increased NCTD solubility 10-fold compared to water. The developed nanoemulsion showed a good droplet size and homogeneity, with adequate pH and viscosity for skin application. In vitro drug release studies showed a sustained release profile, ideal for prolonged therapeutic effects. Accelerated stability studies proved that the formulation was reasonably stable under stress conditions, with particle separation fingerprints, instability index, particle size, and sedimentation velocity analyses being conducted. To assess the therapeutic potential of the developed formulation, in vitro studies were conducted on melanoma B16F1 cells; results showed an IC50 of 1.026 +/− 0.370 mg/kg, and the cells’ metabolic activity decreased after exposure to the NCTD nanoemulsion. Hence, a new “easy-to-make” nanoformulation with therapeutic potential on melanoma cells was developed, as a possible adjuvant for future melanoma treatment.

Strategies for Solubility and Bioavailability Enhancement and Toxicity Reduction of Norcantharidin. Molecules 2022; 27:molecules27227740. [PMID: 36431851 PMCID: PMC9693198 DOI: 10.3390/molecules27227740] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2022] [Revised: 11/01/2022] [Accepted: 11/06/2022] [Indexed: 11/12/2022] Open
Abstract
Cantharidin (CTD) is the main active ingredient isolated from Mylabris, and norcantharidin (NCTD) is a demethylated derivative of CTD, which has similar antitumor activity to CTD and lower toxicity than CTD. However, the clinical use of NCTD is limited due to its poor solubility, low bioavailability, and toxic effects on normal cells. To overcome these shortcomings, researchers have explored a number of strategies, such as chemical structural modifications, microsphere dispersion systems, and nanodrug delivery systems. This review summarizes the structure-activity relationship of NCTD and novel strategies to improve the solubility and bioavailability of NCTD as well as reduce the toxicity. This review can provide evidence for further research of NCTD.

Abstract
BACKGROUND Norcantharidin (NCTD) has a certain degree of hydrophilicity and poor lipophilicity, and has some side-effects, including short t1/2, vascular irritation, cardiotoxicity and nephrotoxicity, which bring difficulties for formulation research. In this study, we aim to develop a novel nanocarrier to improve encapsulation efficiency, increase sterilization stability and enhance antitumor activity. METHODS Phospholipid complexes methods were used for increasing the lipophilicity of norcantharidin (NCTD), then NCTD phospholipid complexes were not only loaded in the oil phase and oil-water interface surface, but also encapsulated in phospholipid bilayers to obtain NCTD liposome-emulsion hybrid (NLEH) delivery system. The in vitro cytotoxicity and apoptosis, in vivo tissue distribution, tumor penetration, heterotopic and orthotopic antitumor studies were conducted to evaluate therapeutic effect. RESULTS NLEH exhibited an improved encapsulation efficiency (89.3%) and a better sterilization stability, compared to NCTD liposomes and NCTD emulsions. NLEH can achieve a better antitumor activity by promoting absorption (1.93-fold), prolonging blood circulation (2.08-fold), enhancing tumor-targeting accumulation (1.19 times), improving tumor penetration, and increasing antitumor immunity. CONCLUSIONS The liposome-emulsion hybrid (LEH) delivery system was potential carrier for NCTD delivery, and LEH could open opportunities for delivery of poorly soluble anticancer drugs, especially drugs that are more hydrophilicity than lipophilicity.

Intratumoral Administration of Thermosensitive Hydrogel Co-Loaded with Norcantharidin Nanoparticles and Doxorubicin for the Treatment of Hepatocellular Carcinoma. Int J Nanomedicine 2021; 16:4073-4085. [PMID: 34163160 PMCID: PMC8214546 DOI: 10.2147/ijn.s308057] [Citation(s) in RCA: 38] [Impact Index Per Article: 12.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2021] [Accepted: 05/19/2021] [Indexed: 02/06/2023] Open
Abstract
Background The efficacy of systemic chemotherapy for hepatocellular carcinoma (HCC) is predominantly hampered by low accumulation in tumor tissue and the high systemic toxicity of anticancer drugs. In this study, we designed an in situ drug-loaded injectable thermosensitive hydrogel system for the simultaneous delivery of norcantharidin-loaded nanoparticles (NCTD-NPs) and doxorubicin (Dox) via intratumoral administration to HCC tumors. Methods NCTD-NPs were prepared by the thin film dispersion method using PCEC polymers as the carrier. Then, NCTD-NPs and Dox were co-encapsulated in a thermosensitive hydrogel based on Pluronic F127 (PF127) to construct a dual drug-loaded hydrogel system. The rheological properties of the drug-loaded hydrogel were studied using a rheometer. Drug release of the drug-loaded hydrogel and cytotoxicity in HepG2 cells were evaluated in vitro. An H22 tumor-bearing mice model was used to assess the in vivo antitumor activity of the drug-loaded hydrogel via intratumoral administration. Results The prepared drug-loaded hydrogel exhibited good thermal-sensitive properties, which remained liquid at room temperature and rapidly transformed into a non-flowing gel at body temperature, and released the drugs in a sustained manner. In vitro studies revealed that the drug-loaded hydrogel exhibited remarkable antiproliferative activity in HepG2 cells compared to free drugs. In vivo antitumor efficacy experiments showed that the drug-loaded hydrogel significantly suppressed tumor growth, alleviated side effects, and prolonged the survival time of mice bearing H22 tumors compared to the other groups. Moreover, immunohistochemical staining revealed that the expression of Ki-67 and CD31 in the drug-loaded hydrogel group was significantly lower than that in the other groups (P < 0.05), indicating that the drug-loaded hydrogel effectively inhibited tumor proliferation and angiogenesis. Conclusion The formulated hybrid thermosensitive hydrogel system with sustained drug release and enhanced therapeutic efficacy was demonstrated to be a promising strategy for the local-regional treatment of HCC via intratumoral administration.

Docetaxel-Loaded Poly(3HB- co-4HB) Biodegradable Nanoparticles: Impact of Copolymer Composition. NANOMATERIALS 2020; 10:nano10112123.

Abstract
Polyhydroxyalkanoate (PHA) copolymers show a relatively higher in vivo degradation rate compared to other PHAs, thus, they receive a great deal of attention for a wide range of medical applications. Nanoparticles (NPs) loaded with poorly water-soluble anticancer drug docetaxel (DCX) were produced using poly(3-hydroxybutyrate-co-4-hydroxybutyrate), P(3HB-co-4HB), copolymers biosynthesised from Cupriavidus malaysiensis USMAA1020 isolated from the Malaysian environment. Three copolymers with different molar proportions of 4-hydroxybutirate (4HB) were used: 16% (PHB16), 30% (PHB30) and 70% (PHB70) 4HB-containing P(3HB-co-4HB). Blank and DCX-loaded nanoparticles were then characterized for their size and size distribution, surface charge, encapsulation efficiency and drug release. Preformulation studies showed that an optimised formulation could be achieved through the emulsification/solvent evaporation method using PHB70 with the addition of 1.0% PVA, as stabilizer and 0.03% VitE-TPGS, as surfactant. DCX-loaded PHB70 nanoparticles (DCX-PHB70) gave the desired particle size distribution in terms of average particle size around 150 nm and narrow particle size distribution (polydispersity index (PDI) below 0.100). The encapsulation efficiency result showed that at 30% w/w drug-to-polymer ratio: DCX- PHB16 NPs were able to encapsulate up to 42% of DCX; DCX-PHB30 NPs encapsulated up to 46% of DCX and DCX-PHB70 NPs encapsulated up to 50% of DCX within the nanoparticle system. Approximately 60% of DCX was released from the DCX-PHB70 NPs within 7 days for 5%, 10% and 20% of drug-to-polymer ratio while for the 30% and 40% drug-to-polymer ratios, an almost complete drug release (98%) after 7 days of incubation was observed.

Abstract
The objectives of the present investigations are (1) to envisage a risk assessment plan for nonphospholipid-based topical ophthalmic emulsions with the help of failure mode and effect analysis (FMEA), (2) to screen the risky formulation and process variables by the Taguchi design, (3) to optimize systematically an emulsion formula by face-centered central composite design (CCD), (4) to incorporate cyclosporin A (0.05 or 0.1% w/w) into the optimized emulsions and predict the in vitro drug release kinetic via a particle diffusion-controlled mathematical model equation, and (5) to assess the emulsion's toxicity using in vitro hemolysis study. Through the risk priority number (RPN) scores of FMEA, half-normal and Pareto charts of the Taguchi design, 3D-response surface graphs, and overlay plots of CCD, the emulsion formula was systematically optimized. Irrespective of the two different drug loadings into optimized emulsions, the drug entrapment efficiency values ranged from 73.20 ± 0.13 to 74.42 ± 0.15%. The film diffusion or ion-exchange process fails to interpret the in vitro drug release kinetic profile. A permissible percentage hemolysis value of above 10% but below 25% guidance was observed for emulsions with or without cyclosporin A. The systematically optimized phospholipidless ophthalmic emulsions could further be exploited commercially for managing dry-eye syndrome.

Abstract
Ginger (GIN) powder-loaded oil-in-water (o/w) macroemulsions were prepared based on olive-and silicone-oils. The dispersed oil droplets with paired-beans structure were evident and thus the final emulsion can be termed as Janus macroemulsions. The objectives of the present study are (1) to identify the marker compound present in GIN powder via HPLC analysis, (2) to process the GIN powder via anti-solvent precipitation technique, (3) to see the solubility of GIN powder in various single oils or oil combination, (4) to optimize the GIN-loaded o/w macroemulsions using the central composite design (CCD) with respect to mean particle size of dispersed oil droplets and highest percentage drug entrapment efficiency values (DEE) and (5) to evaluate the pain reducing activity of optimized GIN-loaded macroemulsion via in vivo primary dysmenorrhea (PD) mice model. Both predicted and obtained values of percentage DEE (76.29 Vs.76.09) and mean particle size (245.99 Vs. 272.51 μm) were almost the same indicating the CCD statistical design applicability. The optimized Janus macroemulsion was stable at 4 °C for over a period of 90 days. Using the PD mice model, the counting of writhing reaction produced by the tested GIN-loaded macroemulsions at low and high doses did not reveal significant difference in comparison to the positive control (aspirin treated). Only the high dose of GIN-loaded macroemulsion was able to restore the uterine tissue's normal histomorphological structure after the H & E staining. Nevertheless, the paired beans structure should be tested for entrapping the plant-derived drugs having dissimilar physicochemical characteristics but similar therapeutic activity.

Abstract
Background Norcantharidin (NCTD), a demethylated derivative of cantharidin (defensive toxin of blister beetles), has been reported to exhibit insecticidal activity against various types of agricultural pests. However, NCTD applications are limited by its poor water solubility and high dosage requirement. Nanoemulsions have attracted much attentions due to the transparent or translucence appearance, physical stability, high bioavailability and non-irritant in nature. In general, nanoemulsions with small droplet size can enhance the bioavailability of drugs, whereas this phenomenon is likely system dependent. In present study, NCTD nanoemulsions were developed and optimized to evaluate and improve the insecticidal activity of NCTD against Plutella xylostella (Lepidotera: Plutellidae) by a spontaneous emulsification method. Results Triacetin, Cremophor EL and butanol were selected as the constituents of NCTD nanoemulsions via solubility determination, emulsification efficiency and ternary phase diagram construction. Insecticidal activity of NCTD nanoemulsion was associated with the content of surfactant and cosurfactant: (1) Higher effective toxicity exhibited at Smix (surfactant to cosurfactant mass ratio) = 3:1 that may be associated with the changes in interfacial tension; (2) NCTD nanoemulsion at 3:7 < SOR (surfactant to oil mass ratio) < 6:4 was more effective at lower surfactant level, which was attributed to the relatively slow diffusion rate of NCTD hindering by excess surfactant. Interestingly, nanoemulsions with smaller droplets were not found to be more effective in our study. Conclusions The optimized NCTD nanoemulsion (triacetin/Cremophor EL/butanol (60/20/20, w/w)) exhibited effective insecticidal activity (LC50 60.414 mg/l, LC90 185.530 mg/l, 48 h) than the NCTD acetone solution (LC50 175.602 mg/L, LC90 303.050 mg/L, 48 h). Spontaneous emulsifying nanoemulsion employed to formulate this poor water-soluble pesticide is a potential system for agriculture application.

Abstract
This report demonstrated a one-step assembly for co-delivering chemotherapeutics and therapeutic nucleic acids, constructed by integrating drug molecules into a nucleic acid condensing polymeric prodrug through degradable linkages. Demethylcantharate was selected as the model drug and pre-modified by esterifying its two carboxylic groups with 2-hydroxyethyl acrylate. The synthesized demethylcantharate diacrylate was then used to polymerize with linear polyethyleneimine (PEI 423) through a one-step Michael-addition reaction. The obtained cationic polymeric demethylcantharate prodrug was used to pack Akt1 shRNA into complexes through a one-step assembly. The formed complexes could release the parent drug demethylcantharate and Akt1 shRNA through the hydrolysis of ester bonds. Cellular assays involving cell uptake, cytotoxicity, and cell migration indicated that demethylcantharate and Akt1 shRNA co-delivered in the present form significantly and synergistically suppress the growth and metastasis of three human cancer cells. This work suggests that incorporating drug molecules into a nucleic acid-packing cationic polymer as a polymeric prodrug in a degradable form is a highly convenient and efficient way to co-deliver drugs and nucleic acids for cancer therapy.

Abstract
The objectives of the current investigation are (1) to prepare and characterize (particle size, surface charge (potential zeta), surface morphology by transmission electron microscopy, drug content, and drug release) the azithromycin (AZM, 100 mg)-loaded oil-in-water (o/w) macroemulsion, (2) to assess the toxicity of macroemulsion with or without AZM using RBC lysis test in comparison with AZM in phosphate buffer solution of pH 7.4, (3) to compare the in vitro antimicrobial activity (in Escherichia coli using zone inhibition assay) of AZM-loaded macroemulsion with its aqueous solution, and (4) to assess the in vitro anti-inflammatory effect (using egg albumin denaturation bioassay) of the AZM-loaded macroemulsion in comparison with diclofenac sodium in phosphate buffer solution of pH 7.4. The AZM-loaded macroemulsion possessed the dispersed oil droplets with a mean diameter value of 52.40 ± 1.55 μm. A reversal in the zeta potential value from negative (-2.16 ± 0.75 mV) to positive (+6.52 ± 0.96 mV) was noticed when AZM was added into the macroemulsion. At a 1:5 dilution ratio, 2.06 ± 0.03 mg of drug was released from macroemulsion followed by 1.01 ± 0.01 and 0.25 ± 0.08 mg, respectively, for 1:10 and 1:40 dilution ratios. Antimicrobial activity maintenance and significant reduction of RBC lysis property were noticed for AZM after loaded in the macroemulsion. However, an increment in the absorbance values for emulsion-treated samples in comparison to the control samples was noticed in the anti-inflammatory test. This speculates the potential of the AZM-loaded emulsion to manage inflammatory conditions produced at Acne vulgaris.

The diacid metabolite of norcantharidin (DM-NCTD) is clinically effective against hepatocellular carcinoma (HCC), but is limited by its short half-life and high incidence of adverse effects at high doses. We developed a DM-NCTD-loaded, folic acid (FA)-modified, polyethylene glycolated (DM-NCTD/FA-PEG) liposome system to enhance the targeting effect and antitumor potency for HCC at a moderate dose based on our previous study. The DM-NCTD/FA-PEG liposome system produced liposomes with regular spherical morphology, with mean particle size approximately 200 nm, and an encapsulation efficiency >80%. MTT cytotoxicity assays demonstrated that the DM-NCTD/FA-PEG liposomes showed significantly stronger cytotoxicity effects on the H22 hepatoma cell line than did PEG liposomes without the FA modification (P<0.01). We used liquid chromatography–mass spectrometry for determination of DM-NCTD in tissues and tumors, and found it to be sensitive, rapid, and reliable. In addition, the biodistribution study showed that DM-NCTD liposomes improved tumor-targeting efficiency, and DM-NCTD/FA-PEG liposomes exhibited the highest efficiency of the treatments (P<0.01). Meanwhile, the results indicated that although the active liposome group had an apparently increased tumor-targeting efficiency of DM-NCTD, the risk to the kidney was higher than in the normal liposome group. With regard to in vivo antitumor activity, DM-NCTD/FA-PEG liposomes inhibited tumors in H22 tumor-bearing mice better than either free DM-NCTD or DM-NCTD/PEG liposomes (P<0.01), and induced considerably more significant cellular apoptosis in the tumors, with no obvious toxicity to the tissues of model mice or the liver tissue of normal mice, as shown by histopathological examination. All these results demonstrate that DM-NCTD-loaded FA-modified liposomes might have potential application for HCC-targeting therapy.

Abstract
Disulfiram (DSF) has been used to treat alcoholism for many years and it has been suggested to play a key role in combatting many kinds of tumors. However, disulfiram has complex pharmacokinetics and is rapidly eliminated which limits its use as a tumor treatment. Therefore, a rapid and sensitive analytical method based on ultra performance liquid chromatography coupled to electrospray ionization-tandem mass spectrometry (UPLC-ESI-MS/MS) was developed and validated for the determination of disulfiram in rat plasma. Blood samples were pre-stabilized with a stabilizing agent and then plasma was obtained and subjected to solid phase extraction (SPE), and chromatographed on a Phenomenex Kinetex(®) XB C18 column with gradient elution using a mobile phase consisting of acetonitrile-water (containing 0.1% formic acid and 1mM ammonium acetate) at a flow rate of 0.2mL/min for 3min. Multiple reactions monitoring in positive mode was carried out with disulfiram at 296.95/115.94 and diphenhydramine (internal standard, IS) at 256.14/167.02 over a linear range from 0.6 to 1200ng/mL. The extraction recovery of disulfiram for different concentrations ranged from 75.7% to 78.3%. The intra- and inter-day precision was less than 8.93% and 12.39%, respectively, and the accuracy was within ±7.75%. The validated method was successfully applied to a pharmacokinetic study of disulfiram in rat plasma after oral administration of a dose of 180mg/kg.

Abstract
CONTEXT Celecoxib (CXB, 0.2 g)-loaded anionic and cationic nanosized emulsions were prepared by a well-established combined emulsification method. OBJECTIVES To investigate the effect of non-phospholipid-based cationic and phospholipid-based anionic emulsions on skin retention and anti-inflammatory activity of CXB. METHODS Using Keshary-Chien diffusion cells with cellulose acetate membrane or excised rat skin, in vitro release and skin retention of CXB from solution and emulsions were studied. The anti-inflammatory activity was evaluated by the carrageenan-induced hind paw edema method in Wistar rats. RESULTS The amount of drug released through artificial membrane has decreased from 122.00 ± 0.70 μg/cm(2) for the CXB solution to 55.80 ± 0.70 μg/cm(2) for anionic emulsion, and then further decreased to 24.79 ± 0.90 μg/cm(2) for cationic emulsion. The JSS value obtained with solution, anionic, and cationic emulsions were 6825.79 ± 920.86, 2513.15 ± 382.71, and 1925.67 ± 147.42, respectively. Cationic emulsion showed a significantly higher level (P ≤ 0.05) of drug accumulation in full-thickness rat skin than anionic emulsion, and a substantially lesser percentage inhibition of edema values compared with both solution and anionic emulsion. DISCUSSION AND CONCLUSION Sustained drug release together with increased skin accumulation and simultaneously decreased skin permeation as observed with cationic emulsion should substantiate its suitability as a topical delivery vehicle for CXB.

Abstract
Severe adverse events have been frequently associated with taking the commercially available formulation of α-asarone injection (α-asarone-I). Hence, we sought to develop an intravenous lipid emulsion of α-asarone (α-asarone-LE), where we hypothesized that these adverse events could be prevented. Using a central composite design-response surface methodology, we developed and optimized an emulsion formulation of α-asarone-LE that composed of 10.0% (w/v) soybean oil, 0.4% (w/v) α-asarone, 1.2% (w/v) soybean lecithin, 0.3% (w/v) F68, and 2.2% (w/v) glycerol. The mean particle size of α-asarone-LE was 226±11 nm, the ζ-potential was -25.6±1.2 mV, the encapsulation efficiency was 99.2±0.1% and the drug loading efficiency was 3.45%. Stability, safety, and efficacy studies of α-asarone-LE were systematically investigated and compared to those of α-asarone-I. The α-asarone-LE not only showed a desired stability, but also exhibited excellent safety and improved efficacy in vivo, indicating its great potential for clinical application in the future.

Abstract
To improve the treatment of helminthiasis, filariasis, and colorectal cancer, albendazole-associated chitosan nanoparticles (ABZ-CS-NPs) were prepared using the emulsion crosslinking volatile technique with contained sodium tripolyphosphate as the crosslinking agent and Poloxamer 188 as the auxiliary solvent. The structural characteristics of the NPs were determined using X-ray diffraction to analyze the interaction between CS and the drug. The NPs were then evaluated in terms of their physicochemical characteristics, drug release behavior, in vivo pharmacokinetic parameters, and biodistribution in animal studies. ABZ-loaded NPs with a uniformly spherical particle sizes (157.8 ± 2.82 nm) showed efficient drug loading, encapsulated efficiency, and high physical stability. The drug release from ABZ-CS-NPs was extended over several periods. Kinetic models were then fitted to determine the release mechanisms. ABZ and its metabolite albendazole sulfoxide (ABZSX) were analyzed in rats with mebendazole as the internal standard using reversed-phase high-performance liquid chromatography. Compared with the ABZ suspension groups, the relative bioavailability values of ABZ and ABZSX were 146.05 and 222.15%, respectively. In addition, the plasma concentration versus time curve is consistent with that of the two compartment models in the plasma concentration versus time curve. The results indicate that the ABZ-loaded NPs are promising novel ABZ candidates for passive diffusion in the treatment of hydatid cysts in the liver via oral administration.

Abstract
OBJECTIVE This study engaged in investigation of optimal formulation, characteristics analysis of Brucea javanica oil microemulsion (BJOM) in order to address safety concerns and make recommendations for improvements in BJOM safety during clinical use in vivo. METHODS Pseudo-ternary phase diagram techniques were used to determine the appropriate ratio of surfactant, cosurfactant and oil phases. Subsequent stability testing of BJOM was performed by dilution, centrifugation and accelerated stability testing. The results were expounded through additional assessment utilizing the classical thermostat method to establish the shelf life of the material. These results were utilized to evaluate the safety of BJOM by haemolytic, irritative and allergic testing in vitro. In addition, the cytotoxicity of BJOM was examined using the tetrazolium salt 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), with particular emphasis given to potential uses in cancer treatment. RESULTS The most suitable method of preparation for BJOM was found to be a one to one ratio (Km 1:1) of Solutol HS15 surfactant matched with sorbitol cosurfactant in the ratio. The microemulsion droplets of BJOM possessed a spherical shape, uniform size and average diameter of 23.8 nm. The expiration date of BJOM was found to be 568 d. The safety study demonstrated no hemolysis activity at the experimental BJOM concentrations; however, mild hemolysis was observed at higher concentrations of Brucea javanica oil emulsion (BJOE), a common commercially available product. Irritation observed upon BJOM treatment can be primarily attributed to Brucea javanica oil (BJO) with little influence of BJOM excipients. In addition, BJOM caused no observed hypersensitivity or other visible allergic reactions in guinea pigs. The anticancer activity curves of BJOM and BJOE demonstrate that both BJOM and BJOE inhibit Hela cells, with BJOM demonstrating significantly more dramatic anticancer activity. CONCLUSION An optimal formulation of BJOM superior to commercially available products and safe for medical application such as intravenous injection has been outlined along with its anticancer activity rating.

Abstract
OBJECTIVES The aim of this study was to perform a systematic preclinical evaluation of norcantharidin (NCTD)-loaded intravenous lipid microspheres (NLM). RESEARCH DESIGN AND METHODS Pharmacokinetics, biodistribution, antitumor efficacy and drug safety assessment (including acute toxicity, subchronic toxicity, hemolysis testing, intravenous stimulation and injection anaphylaxis) of NLM were carried out in comparison with the commercial product disodium norcantharidate injection (NI). RESULTS The pharmacokinetics of NLM in rats was similar to that of NI, and a non-linear correlation was observed between AUC and dose. A comparable antitumor efficacy of NLM and NI was observed in mice inoculated with A549, BEL7402 and BCAP-37 cell lines. It was worth noting that the NLM produced a lower drug concentration in heart compared with NI, and significantly reduced the cardiac and renal toxicity. The LD(50) of NLM was twice higher than that of NI. In NLM, over 80% of NCTD was loaded in the lipid phase or bound with phospholipids. Thus, NCTD was sequestered by direct contacting with body fluids and largely avoided distribution into tissues, consequently leading to significantly reduced cardiac and renal toxicity. CONCLUSIONS These preclinical results suggested that NLM could be a useful potential carrier for parenteral administration of NCTD, while providing a superior safety profile.

Abstract
In this paper, two novel liver-targeting nanoparticles, norcantharidin-loaded chitosan nanoparticles (NCTD-CS-NPs) and norcantharidin-associated galactosylated chitosan nanoparticles (NCTD-GC-NPs), were prepared using ionic cross-linkage. The physical properties, particle size, encapsulation efficiency, and drug release characteristics of the nanoparticles were investigated in vitro. To investigate the intestinal absorption mechanisms of the two preparations, a series of experiments was carried out, including in situ circulation method, in vitro everted gut sacs, and Ussing chamber perfusion technique. The absorption rate constants (Ka) of NCTD at different segments were found to be duodenum > jejunum > ileum > colon. The concentration had no distinctive effect on absorption kinetics, suggesting that drug absorption is not dose-dependent. The transport of NCTD was found to be inhibited by P-glycoprotein (P-gp) inhibitor, indicating that NCTD might be the substrate of P-gp. The order of the absorption enhancer effects were as follows: low molecular weight chitosan (CS-8kDa) > high molecular weight chitosan (CS-30kDa) > Poloxamer > sodium dodecyl sulfate (SDS) > sodium deoxycholate (SDCh). The results indicate that the chitosan nanoparticles can improve intestinal absorption of NCTD.

A novel formulation containing polyvinylpyrrolidone (PVP) K30-coated norcantharidin (NCTD) chitosan nanoparticles (PVP–NCTD–NPs) was prepared by ionic gelation between chitosan and sodium tripolyphosphate. The average particle size of the PVP–NCTD–NPs produced was 140.03 ± 6.23 nm; entrapment efficiency was 56.33% ± 1.41%; and drug-loading efficiency was 8.38% ± 0.56%. The surface morphology of NCTD nanoparticles (NPs) coated with PVP K30 was characterized using various analytical techniques, including X-ray diffraction and atomic force microscopy. NCTD and its metabolites were analyzed using a sensitive and specific liquid chromatography-tandem mass spectrometry method with samples from mice and rats. The results indicated the importance of the PVP coating in controlling the shape and improving the entrapment efficiency of the NPs. Pharmacokinetic profiles of the NCTD group and PVP–NCTD–NP group, after oral and intravenous administration in rats, revealed that relative bioavailabilities were 173.3% and 325.5%, respectively. The elimination half-life increased, and there was an obvious decrease in clearance. The tissue distribution of NCTD in mice after the intravenous administration of both formulations was investigated. The drug was not quantifiable at 6 hours in all tissues except for the liver and kidneys. The distribution of the drug in the liver and bile was notably improved in the PVP–NCTD–NP group. The metabolites and excretion properties of NCTD were investigated by analyzing rat feces and urine samples, collected after oral administration. A prototype drug and two metabolites were found in the feces, and seven metabolites in the urine. The primary elimination route of NCTD was via the urine. The quantity of the parent drug eliminated in the feces of the PVP–NCTD–NP group, was 32 times greater than that of the NCTD group, indicating that the NPs dramatically increased the reduction quantity from liver to bile. We conclude that PVP–NCTD–NPs are an adequate formulation for enhancing the absorption of NCTD, and significantly improving therapeutic effects targeting the hepatic system. Decarboxylation and hydroxylation were the dominant metabolic pathways for NCTD. Metabolites were mainly excreted into rat kidney and finally into urine.

Abstract
UNLABELLED N-Trimethyl chitosan (TMC) was synthesized and used to prepare lactosyl-norcantharidin TMC nanoparticles (Lac-NCTD-TMC-NPs) using an ionic cross-linkage process. Lac-NCTD-TMC-NPs with an average particle size of 120.6 ± 1.7 nm were obtained, with an entrapment efficiency of 69.29% ± 0.76%, and a drug-loading amount of 9.1% ± 0.07%. The release of Lac-NCTD-TMC-NPs in vitro was investigated through a dialysis method, and its sustained effect was evident. In the human liver cancer cell line HepG2, the half-maximum inhibiting concentration (IC(50)) of TMC-encapsulated Lac-NCTD (Lac-NCTD-TMC-NPs) was only 24.2% that of free Lac-NCTD at 24 hours. Lac-NCTD induced HepG2 cell death by triggering apoptosis. In vitro cellular uptake and in vivo NIR fluorescence real-time imaging both indicated a high targeting efficacy. In comparison with Lac-NCTD and Lac-NCTD chitosan NPs (Lac-NCTD-CS-NPs ), Lac-NCTD-TMC-NPs had the strongest antitumor activity on the murine hepatocarcinoma 22 subcutaneous model. FROM THE CLINICAL EDITOR In this article the preparation of N-trimethyl chitosan-encapsulated lactosyl-norcantharidin nanoparticles is described that displayed efficient targeting and sustained release in a hepatocarcinoma SC murine model.

Abstract
OBJECTIVE To obtain stable positively charged Azithromycin (AZI) emulsions with a mean droplet size of 120 nm for the treatment of eye diseases. METHODS The emulsions were obtained by using a suitable homogenization process. The physical stability was monitored by measuring the particle size, zeta potential, and visible appearance. The drug entrapment efficiency was measured by both ultracentrifugation and ultrafiltration methods. Compared with a phosphate solution of AZI, the stability profiles of AZI in lipid emulsions at various pH values were monitored by high-performance liquid chromatography. A pharmacokinetic study was performed to determine the drug levels in rabbit tear fluid using Ultra-performance liquid Chromatography-mass spectrometry. RESULTS Almost all the AZI in the lipid emulsion was distributed in the oil phase and small unilamellar liposomes without contact with water, thereby avoiding hydrolysis. The elimination of the AZI lipid emulsions in tear fluid was consistent with the basic linear pharmacokinetic characteristics. The AUC(0-t) of the AZI lipid emulsion (1%, w/v) and aqueous solution drops (1%, w/v) was 1873.58 +/- 156.87 and 1082.46 +/- 179.06 mugh/ml respectively. CONCLUSIONS This study clearly describes a new formulation of AZI lipid emulsion for ocular administration, and lipid emulsions are promising vehicles for ophthalmic drug delivery.

Abstract
UNLABELLED In this study a new chitosan (CS) derivative, galactosylated chitosan (GC), was synthesized and used to prepare norcantharidin-associated GC nanoparticles (NCTD-GC NPs) by taking advantage of the ionic cross-linkage between the molecules of the anti-hepatocarcinoma medicine NCTD and of the GC as carrier. NCTD-GC NPs were obtained with average particle size of 118.68 +/- 3.37 nm, entrapment efficiency of 57.92 +/- 0.40%, and drug-loading amount of 10.38 +/- 0.06%. Several important factors influencing the entrapment efficiency, drug-loading amount, and particle size of NCTD-GC NPs were studied. The characteristics of sustained and pH-sensitive release of NCTD from NCTD-GC NPs in vitro were studied. In addition, in vitro cellular uptake and cytotoxicity of nanoparticles to hepatoma cell lines SMMC-7721 and HepG2 were also investigated. In vitro, and compared to CS-based NCTD-CS NPs, NCTD-GC NPs demonstrated satisfactory compatibility with hepatoma cells and strong cytotoxicity against hepatocellular carcinoma cells. In vivo antitumor activity of NCTD-GC NPs was evaluated in mice bearing H22 liver tumors. NCTD-GC NPs displayed tumor inhibition effect in mice, better than either the free NCTD or the NCTD-CS NPs. As a hepatocyte-targeting carrier, GC NPs are potentially promising for clinical applications. FROM THE CLINICAL EDITOR In this paper, a galactosylated chitosan (GC), was synthesized and norcantharidin (NCTD)-associated galactosylated chitosan nanoparticles (NCTDGC NPs) were generated by coupling NCTD--an anti-hepatocarcinoma drug--and GC as carrier. Compared to chitosan nanoparticles, NCTD-GC-NPs demonstrated satisfactory compatibility with hepatoma cells and strong cytotoxicity against the cells.

Lipid microspheres loaded with antigenic membrane proteins of the Leishmania amazonensis as a potential biotechnology application. J Colloid Interface Sci 2009; 340:112-8.

Abstract
Lipid microspheres (LM) are excellent drug delivery or vaccines adjuvant systems and are relatively stable. The aim of this work is to develop and characterize a system that is able to encapsulate and present antigenic membrane proteins from Leishmania amazonensis. Membrane proteins are important for vaccine's formulation because these proteins come in contact with the host cell first, triggering the cell mediated immune response. This is a useful tool to avoid or inactivate the parasite invasion. The LM are constituted by soybean oil (SO), dipalmitoylphosphatidilcholine (DPPC), cholesterol and solubilized protein extract (SPE). The particles formed presented an average diameter of 200 nm, low polydispersion and good stability for a period of 30 days, according to dynamic light scattering assays. Isopycnic density gradient centrifugation of LM-protein showed that proteins and lipids floated in the sucrose gradient (5-50%w/v) suggesting that the LM-protein preparation was homogeneous and that the proteins are interacting with the system. The results show that 85% of SPE proteins were encapsulated in the LM. Studies of cellular viability of murine peritoneal macrophages show that our system does not present cytotoxic effect for the macrophages and still stimulates their NO production (which makes its application as a vaccine adjuvant possible). LM-protein loaded with antigenic membrane proteins from L. amazonensis seems to be a promising vaccine system for immunization against leishmaniasis.

Abstract
Docetaxel is a potent anticancer drug. However, there continues to be a need for alternative docetaxel delivery systems to improve its efficacy. We reported the engineering of a novel spherical nanoparticle formulation ( approximately 270 nm) from lecithin-in-water emulsions. Docetaxel can be incorporated into the nanoparticles, and the resultant docetaxel-nanoparticles were stable when stored as an aqueous suspension. The release of the docetaxel from the nanoparticles was likely caused by a combination of diffusion and Case II transport. The docetaxel-in-nanoparticles were more effective in killing tumor cells in culture than free docetaxel. Moreover, the docetaxel-nanoparticles did not cause any significant red blood cell lysis or platelet aggregation in vitro, nor did they induce detectable acute liver damage when injected intravenously into mice. Finally, compared to free docetaxel, the intravenously injected docetaxel-nanoparticles increased the accumulation of the docetaxel in a model tumor in mice by 4.5-fold. These lecithin-based nanoparticles have the potential to be a novel biocompatible and efficacious delivery system for docetaxel.

Abstract
The entrapment efficiency (EE) and release in vitro are very important physicochemical characteristics of puerarin submicron emulsion (SME). In this paper, the performance of ultrafiltration (UF), ultracentrifugation (UC), and microdialysis (MD) for determining the EE of SME were evaluated, respectively. The release study in vitro of puerarin from SME was studied by using MD and pressure UF technology. The EE of SME was 86.5%, 72.8%, and 55.8% as determined by MD, UF, and UC, respectively. MD was not suitable for EE measurements of puerarin submicron oil droplet, which could only determine the total EE of submicron oil droplet and liposomes micelles, but it could be applied to determine the amount of free drug in SMEs. Although UC was the fastest and simplest to use, its results were the least reliable. UF was still the relatively accurate method for EE determination of puerarin SME. The release of puerarin SME could be evaluated by using MD and pressure UF, but MD seemed to be more suitable for the release study of puerarin emulsion. The drug release from puerarin SME at three drug concentrations was initially rapid, but reached a plateau value within 30 min. Drug release of puerarin from the SME occurred via burst release.

Abstract
A sensitive, simple and selective high-performance liquid chromatography-tandem mass spectrometry method was developed and applied to the determination of norcantharidin concentration in human serum. Norcantharidin (NCTD) and cyclophosphamide (IS) in serum were extracted with acetone, separated on a C18 reversed-phase column, gradiently eluted with a mobile phase of acetonitrile-water containing 2 mm ammonium acetate and 0.1% formic acid (pH 3), ionized by positive ion pneumatically assisted electrospray and detected in the multi-reaction monitoring mode using precursor-->product ions of m/z 169.3-->123.1 for NCTD and 261.2-->140.2 for IS, respectively. The linear range of the calibration curve for NCTD was 2.5-50 ng/mL, with a lowest limit of quantification of 2.5 ng/mL, and the intra/inter-day RSD was less than 10%. The method was suitable for determination of low NCTD concentration in human serum after therapeutic oral doses, and has been successfully used for pharmacokinetic studies in healthy Chinese volunteers.
