Salabat, Alireza;Parsi, Elham research published 《 Ex vivo evaluation of celecoxib release from ionic liquid-based microemulsions and microemulgels for topical applications》, the research content is summarized as follows. The aim of this study was to introduce new ionic liquid (IL)-based microemulsions and microemulgels as topical delivery systems for celecoxib. Ex-vivo diffusion of celecoxib loaded in IL-based microemulsions and microemulgels through the rat skin by using Franz diffusion cell was investigated and compared with traditional microemulsions. The investigated systems composed of the same nonionic surfactant/co-surfactant of tween-80/transcutolP, and different oil phases of [BMIM][PF₆], [OMIM][PF₆] and iso-Pr myristate, for construction of ILs/W and O/W microemulsions. The particle size of the ILs/W and O/W microemulsion systems was determined by DLS method. The ex-vivo release results of ILs/W and O/W formulations, at similar conditions, showed that the celecoxib permeability of the ILs/W formulations is more than that of the O/W formulation, either as microemulsion or as microemulgel. As an interesting result, the celecoxib release percent and release rate from the ILs/W systems was more and faster than the O/W system. The kinetic mechanism for ILs/W systems had followed from first-order model and for O/W systems followed Higuchi zero-order model.

Sakurai, Shuhei;Kawakami, Yuta;Kuroki, Manabu;Gotoh, Hiroaki research published 《 Structure-antioxidant activity (oxygen radical absorbance capacity) relationships of phenolic compounds》, the research content is summarized as follows. Antioxidant capacity is the extent to which a compound can eliminate reactive oxygen species, and in vitro methods for its chem. evaluation have been proposed. Among these methods, the oxygen radical absorbance capacity (ORAC) assay comes close to the oxidation reaction in the living body because it generates radical species that mimic the lipid peroxyl radical involved in the peroxidation reaction of biol. components and react in a phosphate buffer. In this study, PM7, a semi-empirical MO method, was used to calculate the thermodn. properties (bond dissociation enthalpy, ionisation potential and proton affinity) associated with ORAC. We also applied the clusterwise linear regression anal. as a statistical method for grouping the antioxidants by structure. By analyzing the data for antioxidants, the trend in the hydrophilic ORAC values was determined using the calculated structures and bond dissociation enthalpies of the groups classified according to the presence or absence of oxygen functional groups in the ortho position of phenol. Further studies of indicators other than bond dissociation enthalpy are needed to predict the ORAC of other antioxidants such as flavonoids and indoles.

Sakamoto, Kentarou;Michibata, Junya;Hirai, Yusuke;Ide, Akiko;Ikitoh, Asuka;Takatani-Nakase, Tomoka;Futaki, Shiroh research published 《 Potentiating the Membrane Interaction of an Attenuated Cationic Amphiphilic Lytic Peptide for Intracellular Protein Delivery by Anchoring with Pyrene Moiety》, the research content is summarized as follows. We previously reported an approach for intracellular protein delivery by attenuating membrane-lytic activity of cationic amphiphilic peptides on cell surfaces. HAad is one such peptides that cytosolically delivers proteins of interest, including antibodies, by stimulating their endosomal escape. Addnl., HAad elicits ruffling of cell membrane, accompanied by transient membrane permeabilization, allowing for the efficient cytosolic translocation of proteins. In this study, we prepared a conjugate of HAad with pyrenebutyric acid as a membrane-anchoring unit (pBu-HAad). pBu-HAad demonstrated protein delivery into cells with only 1/20 concentration of HAad. However, the conjugates with cholesteryl hemisuccinate and aliphatic fatty acids (C = 3, 6, and 10) did not yield such marked effects. The results of time-course and inhibitor studies suggest that the membrane anchoring of HAad by a pyrene moiety leads to enhanced peptide-membrane interaction and to loosen lipid packing, thus facilitating cytosolic translocation through membranes.

Flutamide which is used to treat prostate cancer and other diseases induces liver damage during and after the therapy. The aim of this study was to develop a flutamide/piperineco-loaded self-emulsifying drug delivery system (FPSEDDS) to inhibit flutamide-induced liver injury by utilizing piperine as a metabolic inhibitor. The development of SEDDS was carried out following a quality by design (QbD) approach. The risk assessment study was performed to identify critical quality attributes (CQAs) and critical material attributes (CMAs)/critical process parameters (CPPs). I-optimal mixture design was executed with three CMAs as the independent variables and CQAs as the dependable variables. The effectiveness of optimized SEDDS to circumvent flutamide-induced hepatotoxicity was assessed in mice. The numerical optimization suggested an optimal formulation with a desirability value of 0.621, using CQAs targets as optimization goals with 95% prediction intervals (α = 0.05). The optimal formulation exhibited the grade A SEDDS characteristics with the guarantee of high payloads in self-formed oily droplets. The design space was also obtained from the same optimization goals. All CQA responses of verification points were found within the 95% prediction intervals of the polynomial models, indicating a good agreement between actual vs. predicted responses within the design space. These obtained responses also passed CQAs acceptance criteria. Finally, hematoxylin-eosin staining revealed the minimal flutamide-induced hepatotoxicity from the optimal SEDDS formulation as compared to the control and flutamide/piperine normal suspension. We demonstrate that the piperine containing optimized SEDDS formulation developed by QbD significantly reduces the flutamide-induced liver injury in mice.

Ryan, Philip;Shi, Yun;von Itzstein, Mark;Rudrawar, Santosh research published 《 Novel bisubstrate uridine-peptide analogs bearing a pyrophosphate bioisostere as inhibitors of human O-GlcNAc transferase》, the research content is summarized as follows. Protein O-linked β-D-N-acetylglucosamine (O-GlcNAc) modification (O-GlcNAcylation), an essential post-translational as well as co-translational modification, is the attachment of β-D-N-acetylglucosamine to serine and threonine residues of nucleocytoplasmic proteins. An aberrant O-GlcNAc profile on certain proteins has been implicated in metabolic diseases such as diabetes and cancer. Inhibitors of O-GlcNAc transferase (OGT) are valuable tools to study the cell biol. of protein O-GlcNAc modification. In this study we report novel uridine-peptide conjugate mols. composed of an acceptor peptide covalently linked to a catalytically inactive donor substrate analog that bears a pyrophosphate bioisostere and explore their inhibitory activities against OGT by a radioactive hOGT assay. Further, we investigate the structural basis of their activities via mol. modeling, explaining their lack of potency towards OGT inhibition.

Ruokolainen, Joonas;Hyttinen, Marko;Sorvari, Jouni;Pasanen, Pertti research published 《 Exposure of cleaning workers to chemical agents and physical conditions in swimming pools and spas》, the research content is summarized as follows. Swimming pools and spas require a high hygiene level, and therefore constant cleaning. In this study, cleaning worker′s exposure to volatile organic compounds (VOCs), trichloramine (TCA), and particulate matter (PM) in the swimming pools and spas were evaluated. Also, statistical methods were employed to determine what activities affect the exposure to disinfection byproducts (DBPs). The study was conducted in 32 swimming pools and spas. The measurement locations were pool areas, bathrooms, and locker rooms, both during cleaning and opening hours. During the cleaning, the total volatile organic compound (TVOC) concentrations were low, on average 96, 251, and 91 μg/m³ for locker rooms, bathrooms, and pool areas, resp. Similarly, during the opening hours, the TVOC concentrations were on average 78, 125, and 83 μg/m3, for locker rooms, bathrooms, and pool areas, resp. This is in line with previous studies investigating cleaning work in other environments. The most prevalent compounds during the cleaning were 2-(2-butoxyethoxy)ethanol (DEGBE), 2-(2-ethoxyethoxy)ethanol (DEGEE), 2-butyl-1-octanol, trichloromethane (chloroform), decamethylcyclopentasiloxane (D5), and carbon tetrachloride. The most prevalent compounds during the opening hours were D5, D-limonene, carbon tetrachloride (bathrooms and pool areas), and trichloromethane (bathrooms and pool areas). The TCA concentrations during the cleaning in the bathrooms and pool areas were on average 60 and 67 μg/m³, resp., and during the opening hours, 28 and 122 μg/m³, resp. The use of disinfectants was found to increase the TCA concentration in the bathrooms, while the other cleaning products did not. Even though the TCA concentrations were below the WHO′s guideline and the Finnish occupational exposure limit value of 500 μg/m³, the measured TCA levels were occasionally high enough to pose a risk of irritative symptoms. The PM concentrations were low, both in the real-time monitoring (aerodynamic diameter, Dae ≤ 15 μm) and inhalable dust samples (Dae ≤ 100 μm). Highest measured inhalable dust concentration was 350 μg/m³, well below the Finnish occupational limit value of 5,000 μg/m³ for organic inhalable dust.

Ruiz-Alcaraz, Antonio Jose;Martinez-Sanchez, Maria Antonia;Garcia-Penarrubia, Pilar;Martinez-Esparza, Maria;Ramos-Molina, Bruno;Moreno, Diego A. research published 《 Analysis of the anti-inflammatory potential of Brassica bioactive compounds in a human macrophage-like cell model derived from HL-60 cells》, the research content is summarized as follows. Chronic inflammatory diseases are major causes of global morbidity and mortality. Acute inflammation is meant to protect the body against foreign agents, but it also plays a major role in tissue repairment. Several mediators are involved in this process, including pro-inflammatory cytokines produced by macrophages. Occasionally, if the inflammatory response is not resolved, the acute inflammatory process can evolve into a chronic inflammation. Natural compounds from vegetables are considered as an important source of active agents with potential to treat or prevent inflammatory related pathologies and could be used as an alternative of the therapeutic agents currently in use, such as non-steroidal anti-inflammatory drugs (NSAIDs), which present several side effects. In this research work we evaluated in vitro the anti-inflammatory activity of a series of ten phytochems. present in Brassica, measured as the potential of those compounds to reduce the production of key pro-inflammatory cytokines (TNF-α, IL-6 and IL-1β) by a human macrophage-like cell model of HL-60 cellsMost of the tested phytochems. (including the most representative bioactive mols. of the major classes of compounds present in cruciferous foods such as glucosinolates, isothiocyanates, hydroxycinnamic acids, flavonols and anthocyanins) demonstrated significant anti-inflammatory activity at micromolar level in the absence of cytotoxic effects in this human macrophage-like cell model. These data confirm that phytochems. commonly obtained from Brassica may be potential therapeutic leads to treat or prevent human chronic inflammation and related diseases.

Rostami, Amir;Baluchnejadmojarad, Tourandokht;Roghani, Mehrdad research published 《 Sinapic acid ameliorates paracetamol-induced acute liver injury through targeting oxidative stress and inflammation》, the research content is summarized as follows. Acetaminophen (paracetamol, APAP) overdose is the principal cause of acute liver injury (ALI) that leads to liver failure typified with oxidative stress, mitochondrial and lysosomal dysfunction and with few antidotes for this condition. Therefore, more effective therapeutics are urgently required. Sinapic acid is a phenolic phytochem. with significant antioxidant, anti-inflammatory and hepatoprotective potential. This study was conducted to evaluate hepatoprotective effect of this phytochem. in acetaminophen-induced model of ALI. Male C57BL/6 mice were treated p.o. with sinapic acid (10 or 50 mg/kg) 3 times at 72, 24, and 1 h before APAP (300 mg/kg; i.p.) challenge. Functional factors of liver dysfunction were determined along with hepatic assessment of oxidative stress and inflammatory indexes and histopathol. anal. was also conducted. Sinapic acid (50 mg/kg) properly decreased serum levels of ALT, ALP, and AST besides reducing liver level of ROS, MDA, IL-6, TNF-α, NF-kB, and MPO and improved sirtuin 1, HO-1, Nrf2, SOD activity, and MMP with no significant effect on IL-1β and catalase activity in addition to decreasing activity of lysosomal enzymes including cathepsin B and β-galactosidase. Also, sinapic acid at the higher dose ameliorated liver histopathol. changes due to APAP and properly reversed NF-kB and Nrf2 immunoreactivity. These findings show that sinapic acid pretreatment effectively protects liver against adverse and hepatotoxic effect of APAP through its antioxidant- and anti-inflammatory potential linked to NF-kB/Nrf2/HO-1 signaling and also via regulation of sirtuin 1, mitochondrial integrity, and lysosomal stabilization.

Abstract: This study explored the design of supersaturable self-microemulsifying drug delivery systems (S-SMEDDS) to address poor solubility and oral bioavailability of a novel benzimidazole derivative anticancer drug (BI). Firstly, self-microemulsifying drug delivery systems SMEDDS made of Miglyol 812, Kolliphor RH40, Transcutol HP, and ethanol were prepared and loaded with the BI drug. Upon dispersion, the systems formed neutrally charged droplets of around 20 nm. However, drug precipitation was observed following incubation with simulated gastric fluid (pH 1.2). Aiming at reducing this precipitation and enhancing drug payload, supersaturable systems were then prepared by adding 1% hydroxypropyl cellulose as precipitation inhibitor. Supersaturable systems maintained a higher amount of drug in a supersaturated state in gastric medium compared with conventional formulations and were stable in simulated intestinal medium (pH 6.8). In vitro cell studies using Caco-2 cell line showed that these formulations reduced in a transient manner the transepithelial elec. resistance of the monolayers without toxicity. Accordingly, confocal images revealed that the systems accumulated at tight junctions after a 2 h exposure. In vivo pharmacokinetic studies carried out following oral administration of BI-loaded S-SMEDDS, SMEDDS, and free drug to healthy mice showed that supersaturable systems promoted drug absorption compared with the other formulations. Overall, these data highlight the potential of using the supersaturable approach as an alternative to conventional SMEDDS for improving oral systemic absorption of lipophilic drugs.
