Sawale, Sunil Rambhau;Shete, R. V.;Bhagat, Vishwas C.;Deshmukh, Madhuri T. research published 《 Nanostuctured lipid based drug delivery system of lopinavir- optimization and evaluation》, the research content is summarized as follows. By using the high-shear homogenization method Nanostructured lipid carriers (NLCs) loaded with lopinavir (LOP) were prepared The LOPNLCs formulations were freeze-dried using POLOXOMER 188 as a cryoprotectant. A burst release is shown by in vitro release studies in simulated gastric fluid (pH 1.2) and simulated intestinal fluid (pH 6.8). The optimized freeze-dried formulation (LOP-NLC) had a particle size (PS), zeta potential (ZP) and % entrapment efficiency (%EE) of 159.5 _ 3.75 nm, 0.413 _ 0.017, -46 mV and 97.77 _ 4.46%, resp. A spherical shape was observed in the optimized formulation by transmission and scanning electron microscopes. The absence of chem. interaction between the drug and lipids is observed in Differential scanning Calorimetry study. In vitro study is performed using the bulk-equilibrium reverse dialysis technique, to investigate LOP release from optimized LOP-NLC and pure drug suspension in different media. The optimized formulations stored in amber glass container were found to be phys. and chem. stable for three months at room temperature The bioavailability of LOP following oral administration of LOP-NLC in male Wistar rats was found 4.52-fold higher than the LOP-suspension. So the conclusion is:- for improving the oral bioavailability of lopinavir, the nanostructure lipid carriers are potential carriers.

Saridas, Mehmet Ali;Ag am, Erdal;Akbas, Furkan Cihad;Akyildiz, Asiye;Paydas Kargi, Sevgi research published 《 Comparison of superior bred strawberry genotypes with popular cultivars in terms of fruit bioactive compounds during the wide harvest dates》, the research content is summarized as follows. Secondary compounds of fruit are among the essential concerns due to their pos. effects on human health. Many studies have attempted to improve these compounds by applying different genotype or cultivation practices such as irrigation and fertilization. This study aimed to find out the effect of different harvest dates on strawberry genotypes in terms of total phenolic (TP), total antioxidant activity (TAA), total monomeric anthocyanin (TMA), and some crucial individual phenolic compounds during the five-month growing season (Jan. – May periods) with one month intervals. Besides, superior bred lines (′33′, ′36′ and ′61′) were compared with widely grown cultivars (′Rubygem′, ′Festival′ and ′Fortuna′) under the Mediterranean climate conditions. Regarding the genotypes, it was observed that TMA, TP, TAA, (-) epicatechin, (-) epicatechin gallate, pelargonidin 3- glucoside (P3G), and pelargonidin 3- rutinoside (P3R) values were the highest values in the 33-bred line, while the 36-bred line standed out in terms of ferulic acid and cyanidin 3- glucoside (C3G). This study also has shown that the chlorogenic acid and sinapic acid contents of the 61-bred line were found in the highest level comparing with the others. Regarding the harvest date, fruit antioxidant activity, total phenolic compounds, and individual phenols such as gallic, syringic, ferulic, (-) epicatechin and ellagic acid were measured the highest in May-harvested fruits, whereas these values were observed at the lowest level in March, except for syringic and (-) epicatechin. On the other hand, rutin, quercetin, sinapic acid, chlorogenic and caffeic acids, and P3G and P3R levels of fruits were the highest in Apr., when it was the most intense harvest period in Mediterranean climate conditions. These observations indicated that these compounds could be increased by choosing the right genotype and suitable environmental conditions.

Despite considerable advances in recent years, challenges in delivery and storage of biol. drugs persist and may delay or prohibit their clin. application. Though nanoparticle-based approaches for small mol. drug encapsulation are mature, encapsulation of proteins remains problematic due to destabilization of the protein. Reverse micelles composed of decylmonoacyl glycerol (10MAG) and lauryldimethylamino-N-oxide (LDAO) in low-viscosity alkanes have been shown to preserve the structure and stability of a wide range of biol. macromols. Here, we present a first step on developing this system as a future platform for storage and delivery of biol. drugs by replacing the non-biocompatible alkane solvent with solvents currently used in small mol. delivery systems. Using a novel screening approach, we performed a comprehensive evaluation of the 10MAG/LDAO system using two preparation methods across seven biocompatible solvents with anal. of toxicity and encapsulation efficiency for each solvent. By using an inexpensive hydrophilic small mol. to test a wide range of conditions, we identify optimal solvent properties for further development. We validate the predictions from this screen with preliminary protein encapsulation tests. The insight provided lays the foundation for further development of this system toward long-term room-temperature storage of biologics or toward water-in-oil-in-water biol. delivery systems.

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.
