Singha, L. Ronibala;Das, Malay K. research published 《 Effect of Mesua ferrea Linn. seed kernel oil on percutaneous absorption of Diltiazem hydrochloride through pig ear epidermis: A mechanistic study》, the research content is summarized as follows. The present study reports the mechanistic investigation on Mesua ferrea L. seed kernel oil as a natural skin permeation enhancer. The natural oil was extracted by Soxhlation method. The permeation parameters resulting from the ex vivo skin permeation study of the model drug Diltiazem HCl across oil pre-treated pig ear epidermis revealed better transdermal flux of the test groups compared to the control one. Also, the investigated oil exhibited significantly higher penetration enhancement effect compared to the standard penetration enhancer Transcutol and the maximum permeation enhancement effect was observed at 15% volume/volume in PG. The permeation enhancement mechanistic studies by FT-IR, DSC and SEM suggested that the enhancement effect of the oil was due to the fluidization of lipids and interaction with keratinocytes of the stratum corneum maintaining morphol. integrity of the skin membrane. Furthermore, the test oil was found to be non-irritant in nature and safe for topical application. These findings suggests the Mesua ferrea L. seed oil is an efficient and safe natural skin permeation enhancer providing the scope for future research on its usage in the development of transdermal drug delivery devices.

Sinico, Chiara;Fadda, Anna Maria;Valenti, Donatella;Pireddu, Rosa;Corrias, Francesco;Schlich, Michele;Pitzanti, Giulia;Lai, Francesco research published 《 Nanoliposomes@Transcutol for in vitro skin delivery of 8-methoxypsoralen》, the research content is summarized as follows. The 8-methoxypsoralen is the most common drug in psoralen plus UV light irradiation therapy for the treatment of severe psoriasis. Despite of the efficacy, its classic oral administration leads to several serious adverse effects. However, the topical psoralen application produces a drug skin accumulation lower than that obtained by oral administration, due to the drug low skin permeability. In this paper, 8-methoxypsoralen loaded Penetration Enhancer-contg Vesicles were prepared using soy phosphatidylcholine and the penetration enhancer Transcutol (5% or 10%) and characterized in terms of size, polydispersity index, zeta potential and encapsulation efficiency. No statistically significant differences in both size (∼135 nm) and encapsulation efficiency (∼65%) were found for different Transcutol concentration Transdermal delivery study assessed by Franz diffusion cells, showed that the 8-methoxypsoralen mainly accumulated into the stratum corneum. Moreover, after Penetration Enhancer-contg Vesicles application, the drug recovered in this layer is almost double of that delivered by conventional liposomes, while no significant difference was found from the different Transcutol concentrations Finally, biocompatibility checked by an MTT assay, demonstrated that the incubation of human keratinocytes for 24 h with 8-methoxypsoralen loaded Penetration Enhancer-contg Vesicles did not significantly reduce cell viability.

Subedi, Laxman;Pandey, Prashant;Shim, Jung-Hyun;Kim, Ki-Taek;Cho, Seung-Sik;Koo, Kyo-Tan;Kim, Beum Joon;Park, Jin Woo research published 《 Preparation of topical bimatoprost with enhanced skin infiltration and in vivo hair regrowth efficacy in androgenic alopecia》, the research content is summarized as follows. To prepare a topical formulation of bimatoprost (BIM) with high skin permeability, we designed a solvent mixture system composed of ethanol, diethylene glycol monoethyl ether, cyclomethicone, and butylated hydroxyanisole, serving as a volatile solvent, nonvolatile co-solvent, spreading agent, and antioxidant, resp. The ideal topical BIM formulation (BIM-TF#5) exhibited 4.60-fold higher human skin flux and a 529% increase in dermal drug deposition compared to BIM in ethanol. In addition, compared to the other formulations, BIM-TF#5 maximally activated human dermal papilla cell proliferation at a concentration of 5 muM BIM, equivalent to 10 muM minoxidil. Moreover, BIM-TF#5 (0.3% [weight/weight] BIM) significantly promoted hair regrowth in the androgenic alopecia mouse model and increased the area covered by hair at 10 days by 585% compared to the vehicle-treated mice, indicating that entire telogen area transitioned into the anagen phase. Furthermore, at day 14, the hair weight of mice treated with BIM-TF#5 (5% [weight/weight] BIM) was 8.45- and 1.30-fold greater than in the 5% (weight/weight) BIM in ethanol and 5% (w/v) minoxidil treated groups, resp. In the histol. examination, the number and diameter of hair follicles in the deep subcutis were significantly increased in the BIM-TF#5 (0.3 or 5% [weight/weight] BIM)-treated mice compared to the mice treated with vehicle or 5% (weight/weight) BIM in ethanol. Thus, our findings suggest that BIM-TF#5 is an effective formulation to treat scalp alopecia, as part of a novel therapeutic approach involving direct prostamide F2alpha receptor-mediated stimulation of dermal papilla cells within hair follicles.

Sumimoto, Yusuke;Okawa, Shinya;Inoue, Tomoya;Masuda, Kazufumi;Maruyama, Masato;Higaki, Kazutaka research published 《 Extensive improvement of oral bioavailability of mebendazole, a brick dust, by polymer-containing SNEDDS preparation: Disruption of high crystallinity by utilizing its counter ion》, the research content is summarized as follows. Poorly water-soluble and poorly lipid-soluble drugs are called as ′brick dust′ and it is very hard for them to be formulated as some dosage form which can provide an effective bioavailability after oral administration. Mebendazole (MBZ), an anti-helminthic drug having anti-cancer properties, is one of the brick dusts and its poor bioavailability has been well known. The strategy of the current study was to improve the oral absorption of MBZ by SNEDDS formulation prepared by utilizing an MBZ-counter ion complex, of which the formation would disrupt the high crystallinity of MBZ. Among five different counter ions examined, (+)-10-camphorsulfonic acid (CSA), 2-naphthalene-sulfonic acid (NSA) and p-toluenesulfonic acid (TSA) largely improved MBZ solubility in the SNEDDS vehicle by forming the complex with MBZ. The solid state of these complexes, MBZ-CSA, MBZ-NSA and MBZ-TSA, was suggested to be amorphous by XRPD and DSC. SNEDDS formulations of the three complexes extensively improved MBZ dissolution under gastric and intestinal luminal conditions, compared with MBZ crystalline powder. However, since the dissolved concentrations of MBZ were time-dependently decreased so much by precipitation, we tried to maintain the high dissolution property by applying some polymer for SNEDDS preparation of MBZ-CSA which provided the highest solubility in the SNEDDS vehicle. Among ten different polymers examined, HPMCP-50 successfully maintained the high dissolution property of MBZ-CSA SNEDDS under both gastric and intestinal luminal conditions. In the in vivo oral administration study, SNEDDS preparations for the three MBZ complexes significantly improved MBZ absorption compared with MBZ crystalline powder, but 2% HPMCP-50-containing SNEDDS of MBZ-CSA provided further improvement of MBZ absorption, resulting in around 10-fold of crystalline powder in AUC.

Suram, Dinesh;Veerabrahma, Kishan research published 《 Design and Development of Solid SMEDDS and Liquisolid Formulations of Lovastatin, for Improved Drug Dissolution and In vivo Effects-a Pharmacokinetic and Pharmacodynamic Assessment》, the research content is summarized as follows. Lovastatin (Lov) is a lipid-lowering agent, with 5% bioavailability (BA) due to extensive first pass metabolism and poor solubility To enhance dissolution and in vivo effects, Lov solid self microemulsifying drug delivery system (SMEDDS) and liquisolid systems were developed and evaluated to select superior one. Solubilities were determined in oils, surfactants, and cosurfactants. Ternary phase diagrams were constructed and selected the one which showed maximum emulsion zone. In vitro dissolution, DSC, SEM and PXRD studies were used to characterize the developed formulations. In vivo studies were conducted on optimal formulations in wistar rats. Based on solubilities, Capmul PG8 and Capmul MCM were preferred as oils, Labrasol and Transcutol P as surfactant and cosurfactant. Here, Syloid XDP carrier showed better adsorption capacity among others, hence was used in optimal solid SMEDDS (SX) and liquisolid (LS) formulations. Dissolution study results showed significant improvement in release when compared to pure drug. DSC, SEM, and PXRD results indicated the loss of drug crystallinity in optimal formulations. In pharmacokinetic (PK) study, SX and LS showed 2.57 and 1.43 fold improvements in AUC, when compared to that of coarse suspension (CS). In pharmacodynamic (PD) study, hyperlipidemia was induced by Triton X-100. CS and LS treatments showed a decline in hyperlipidemic levels at 4 h. But, SX-treated group showed early onset of decline at 2 h. Further, the duration of anti-hyperlipidemia was at least 12 h extra when compared to CS and LS. This study confirmed the superiority of SX over LS in PK and PD effects.

Schmied, Fabian-Pascal;Bernhardt, Alexander;Engel, Andrea;Klein, Sandra research published 《 A Customized Screening Tool Approach for the Development of a Self-Nanoemulsifying Drug Delivery System (SNEDDS)》, the research content is summarized as follows. The present study focused on establishing a novel, (pre-)screening approach that enables the development of promising performing self-nanoemulsifying drug delivery systems (SNEDDSs) with a limited number of experiments The strategic approach was based on first identifying appropriate excipients (oils/lipids, surfactants, and co-solvents) providing a high saturation solubility for lipophilic model compounds with poor aqueous solubility Excipients meeting these requirements were selected for SNEDDS development, and a special triangular mixture design was applied for determining excipient ratios for the SNEDDS formulations. Celecoxib and fenofibrate were used as model drugs. Formulations were studied applying a specific combination of in vitro characterization methods. Specifications for a promising SNEDDS formulation were self-imposed: a very small droplet size (< 50 nm), a narrow size distribution of these droplets (PDI < 0.15) and a high transmittance following SNEDDS dispersion in water (> 99% in comparison with purified water). Excipients that provided a nanoemulsion after dispersion were combined, and ratios were optimized using a customized mapping method in a triangular mixture design. The best performing formulations were finally studied for their in vitro release performance. Results of the study demonstrate the efficiency of the customized screening tool approach. Since it enables successful SNEDDS development in a short time with manageable resources, this novel screening tool approach could play an important role in future SNEDDS development.

Shakeel, Faiyaz;Alshehri, Sultan;Ghoneim, Mohammed M.;Martinez, Fleming;Pena, Maria.;Jouyban, Abolghasem;Acree, William E. research published 《 Solubility of tadalafil in aqueous mixtures of Transcutol and PEG 400 revisited: correlation, thermodynamics and preferential solvation》, the research content is summarized as follows. Mole fraction solubilities of tadalafil (3) in aqueous mixtures of Transcutol and PEG 400 at temperatures from 298.15 to 333.15 K were analyzed following Hildebrand solubility parameters. Cosolvency models for representing tadalafil solubility at various temperatures were also provided for correlation/prediction purposes. Apparent thermodn. quantities for tadalafil dissolution processes were calculated based on van′t Hoff and Gibbs equations. Non-linear enthalpy-entropy compensation was observed for tadalafil transfer from more polar to less polar solvent systems. Preferential solvation parameters of tadalafil at 298.15 and 313.15 K were determined by means of the inverse Kirkwood-Buff integrals (IKBI). Tadalafil is preferentially solvated by water in water-rich mixtures of Transcutol but preferentially solvated by Transcutol in mixtures of 0.12 < x1 < 1.00. In the former case, this result could be due to hydrophobic hydration around the non-polar moieties of tadalafil. Otherwise, tadalafil is preferentially solvated by PEG 400 in all the aqueous mixtures

Shamsi, Ali;Hashemian, Saeedeh research published 《 Structural, magnetic and adsorptive properties of nano spinel of cobalt aluminate doped with nickel for Cr(VI) removal》, the research content is summarized as follows. Nanocrystallines of cobalt aluminate spinel doped with Nickel (MAl₂O₄; M = Co²⁺, Ni²⁺) were synthesized by sol-gel method. The MAl2O4 samples were prepared by using aluminum nitrate; cobalt nitrate, nickel nitrate, citric acid and diethylene glycol mono Et ether as precursor materials. The nanocrystallines spinel were characterized by Fourier transform IR spectroscopy (FTIR), X-ray diffraction(XRD), Thermal gravimetric (TGA), Scanning electron microcopy (SEM) with the energy dispersive X-ray spectroscopy (EDX) methods. The Sp. surface area of the synthesized powders was measured with a Brunauer-Emmet-Teller (BET) apparatus using N₂ adsorption. According to obtained XRD patterns the formation of single phase MAl₂O₄ completed up 800 °C. The average crystallite′s sizes spinel and sp. surface area at 800 °C were estimated about 11.07 nm and 154 m² g^-1, resp. The results of SEM anal. show that the nanoparticles shape are as spherical shape, uniform and a little agglomerated. The magnetic behavior of spinels showed the magnetization decreased with increasing nickel ions. Adsorption of Cr(VI) by as prepared spinels were considered. The highest percent of Cr(VI) adsorption was occurred at contact time of 45 min, pH 7.0, and adsorbent dose of 2 g L^-1. The order of adsorption capacity of sorbent samples for Cr(VI) removal was as follow: Ni_0.5Cu_0.5Al₂O₄ >Ni_0.7Cu_0.3Al₂O₄ >Ni0.3Cu0.7Al₂O₄>NiAl₂O₄> CoAl₂O₄. Kinetic studies indicated that the adsorption process follows by pseudo second-order model. Thermodn. results revealed that the adsorption of Cr(VI) is endothermic, spontaneously process and feasible in the range of 298-338 K.

Sharma, Monika;Kaur, Jaswinder;Rakshe, Siddhi;Sharma, Nishant;Khunt, Dignesh;Khairnar, Amit research published 《 Intranasal Exposure to Low-Dose Rotenone Induced Alpha-Synuclein Accumulation and Parkinson′s Like Symptoms Without Loss of Dopaminergic Neurons》, the research content is summarized as follows. Epidemiol. Parkinson′s disease (PD) is associated with chronic ingestion or inhalation of environmental toxins leading to the development of motor symptoms. Though neurotoxin-based animal models played a major role in understanding diverse pathogenesis, they failed to identify the risk assessment due to uncommon route of toxin exposure. Toward this, the available neurotoxin-based intranasal (i.n.) PD models targeting olfactory bulb (OB) have demonstrated the dopaminergic (DAergic) neurodegeneration in both OB and substantia nigra (SN). Despite that, the studies detecting the alpha-synuclein (α-syn) accumulation in OB and its progression to other brain regions due to inhalation of environmental toxins are still lacking. Herein, we developed oil in water microemulsion of rotenone administered intranasally to the mice at a dose which is not detectable in blood, brain, and olfactory bulb by LCMS method. Our data reveals that 9 wk of rotenone exposure did not induce olfactory and motor dysfunction. Conversely, after 16 wk of washout period, rotenone treated mice showed both olfactory and motor impairment, along with α-syn accumulation in the OB and striatum without glial cell activation and loss of dopaminergic neurons. The results depict the progressive nature of the developed model and highlight the role of α-syn in PD like pathol. or symptoms. Together, our findings suggest the adverse consequences of early exposure to the environmental toxins on the olfactory system for a shorter period with relevance to the development of synucleinopathy or Parkinson′s disease in its later stage.

All excess properties are neg. at all temperatures for all the mixtures, suggesting the compactness of binary mixture except the pos. V_m^E values for some concentrations of BA mixtures Deviation from ideality increases with rising temperature for both excess molar volume and excess isentropic compressibility but a decrease in deviation from ideality with temperature rise has been observed for viscosity deviations. Finally, excess properties have been fitted to the Redlich-Kister polynomial.
