Rajamma, Sreeranjini Sukumaran;Krishnaswami, Venkateshwaran;Prabu, Sakthivel Lakshmana;Kandasamy, Ruckmani research published 《 Geophila repens phytosome-loaded intranasal gel with improved nasal permeation for the effective treatment of Alzheimer′s disease》, the research content is summarized as follows. Geophila repens (L.) I. M. Johnst is a creeping herb with good anti-cholinesterase activity and has been used traditionally in India to improve memory and intelligence for many years. The antioxidant activity of the ′methanolic extract of the leaves of Geophila repens′ (MEGR) was determined and found to be high, possibly due to the presence of phenolic compounds, flavonoids, and triterpenoids. The permeation of phytoconstituents through the blood-brain barrier is a challenging factor in the development of phytoformulation for the treatment of Alzheimer′s disease (AD). To overcome these limitations, ′Geophila repens phytosome-loaded intranasal gel′ (MEGR-PG) with enhanced permeation properties through the nasal route to the brain was developed. Here, transcutol was used as permeation enhancer and hydroxypropyl methylcellulose as a gelling agent. For the development of MEGR-PG, a screened phytosome (MEGR: soy phosphatidylcholine, 1: 2) with a particle size of 444.93 ± 25.24 nm, PDI value of 0.358 ± 0.012, spherical morphol., encapsulation efficiency of 51.88 ± 1.025% with an immediate in vitro release of 45.84 ± 5.6% at 60 min followed by a maintenance period of up to 480 min was used. MEGR-PG exhibited significant in vitro nasal mucosa permeation without causing skin irritation. Furthermore, MEGR-PG exhibited a similar proportion of acetylcholinesterase inhibition (97.87 ± 6.84%) in comparison to donepezil (97.17 ± 4.86%) but was greater than MEGR (69.86 ± 5.68%), and it also accelerated angiogenesis, which shows potential to modify the cognitive behavior of AD patients. In addition, the brain targeting effect of MEGR-PG has been confirmed by a preclin. in vivo imaging study. As a result, MEGR-PG is a promising treatment option for AD patients.

Raju, Marina;Kunde, Shalvi Sinai;Auti, Sandip T.;Kulkarni, Yogesh A.;Wairkar, Sarika research published 《 Berberine loaded nanostructured lipid carrier for Alzheimer’s disease: Design, statistical optimization and enhanced in vivo performance》, the research content is summarized as follows. Berberine, an isoquinoline alkaloid, is reported for the treatment of Alzheimer’s disease. Despite having substantial therapeutic potential, it exhibits poor absorption, low oral bioavailability and limited penetration in the brain. In this study, berberine-loaded nanostructured lipid carriers (Berb-NLCs) were developed by melt-emulsification and ultrasonication using Geleol, Miglyol 812 N, Solutol HS 15 as a solid lipid, liquid lipid and surfactant, resp. The Berb-NLC formulation was statistically optimized by a 32 factorial design in which the effect of surfactant and berberine concentration was assessed on particle size and entrapment efficiency of Berb-NLCs. Optimized Berb-NLCs (Trial-5) exhibited particle size of 186 nm, polydispersity index of 0.108, the zeta potential of -36.86 mV and 88% entrapment efficiency. The in vitro release of berberine from Batch-B5 was 82% in phosphate buffer at the end of 24 h. The comparative results of pharmacodynamic studies involving behavioral assessment by locomotor activity, passive avoidance test, elevated plus maze test and spatial memory assessment by Morris water maze demonstrated improved behavioral parameters in vivo by Berb-NLCs compared to pure berberine in Albino Wistar rats. Thus, berberine-loaded nanostructured lipid carriers have the potential of brain targeting and were effective in an animal model of Alzheimer’s disease.

An isocratic RP-HPLC was developed and validated for isolation of 1′-Acetoxychavicol acetate (ACA) from Alpinia galanga extract (AGE). Nucleodur C18 column was used as the stationary phase and mixture of acetonitrile/0.1% formic acid in water (60/40, volume/volume) were used as mobile phase. The elution was carried out with a flow rate of 1 mL/min. Further, the method was validated as per ICH Q2 [R1] guidelines in terms of linearity, LOD, LOQ, recovery, precision and specificity. The validated method was utilized for two purposes i.e. optimizing the isolation of ACA from AGE and quantifying ACA′s concentration and release from its nanoemulsion. To achieve high yield of ACA, Central composite design (CCD) was used to optimize sieve number and solid to solvent ratio. The retention time of standard and isolated ACA were found at 5.63 min and 5.46 min resp. The results indicated that the validated method was linear, accurate, precise and specific. During optimization, excellent correlation was observed between practical yield (3.89 ± 0.23% weight/weight of dried rhizomes) and predicted yield (3.73% weight/weight of dried rhizomes) of ACA with p value more than 0.05. The percentage of ACA loaded in the nanoemulsion was found to be 99.12 ± 0.39. The in vitro diffusion studies showed 90.12 ± 2.21% release of ACA at the end of 24 h. It was concluded that the validated method has been successfully utilized to isolate the ACA from AGE and quantify the amount of ACA present in nanoemulsion.

Romdhani, Asma;Osorio, Irmis P.;Martinez, Fleming;Jouyban, Abolghasem;Acree, William E. Jr research published 《 Further calculations on the solubility of trans-resveratrol in (Transcutol + water) mixtures》, the research content is summarized as follows. Ha et al. reported the equilibrium solubility of trans-resveratrol in some {Transcutol (1) + water (2)} mixtures at several temperatures with some numerical correlation and apparent dissolution thermodn. analyze. Nevertheless, no attempt was made to evaluate the effect of mixtures polarity on solubility nor preferential solvation of this compound by the solvent components. In this communication the effect of Hildebrand solubility parameters of mixtures on trans-resveratrol solubility was discussed. Moreover, the preferential solvation of trans-resveratrol in {Transcutol (1) + water (2)} mixtures at several temperatures was analyzed based on the inverse Kirkwood-Buff integrals as described in the literature. trans-resveratrol is preferentially solvated by water in water-rich mixtures (0.00 < x1 < 0.14) but preferentially solvated by Transcutol in mixtures with composition 0.14 < x1 < 1.00. These results could be interpreted as a consequence of hydrophobic hydration around the aromatic rings of the solute in the former case. The observed trend in the last case could be a consequence of the acid behavior of trans-resveratrol in front of Transcutol mols. because this cosolvent is more basic than water.

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.

Phillips, Robert;Whelton, Andrew J.;Eckelman, Matthew J. research published 《 Incorporating use phase chemical leaching and water quality testing for life cycle toxicity assessment of cross-linked polyethylene (PEX) piping》, the research content is summarized as follows. Life cycle assessment (LCA) is increasingly being considered in material selection decisions for residential drinking water piping, but chem. leaching during the use phase has typically been excluded, even though the delivery of safe water is the core function of water distribution infrastructure. We have quantified the contribution of leached organics to life cycle human toxicity of piping materials through the integration of empirical leaching data within LCA. Eight cross-linked polyethylene (PEX) pipe brands were examined Upstream emissions from PEX pipe production were combined with empirical total organic carbon (TOC) data from leaching tests for new pipes. The total mass of organic contaminants ingested over the pipe′s lifetime was estimated by fitting leaching data with kinetic models and integrating leaching concentrations and daily water use over time, rather than using an initial concentration that does not accurately depict actual lifetime exposures. Potential human toxicity from use phase ingestion was evaluated using a range of human effect factors from the consensus USEtox model to create plausible bounds of toxicity through different exposure and effect scenarios. New non-carcinogenic human toxicol. effect factors were derived for approx. half of the 62 leached organic compounds identified. Results indicate that potential human toxicity from upstream pipe production generally exceeds use phase toxicity, but that leached contaminants can be a substantial contributor to overall life cycle toxicity, depending on the PEX brand, particularly for carcinogenic effects. Deleterious effects can be reduced both by thorough system flushing after initial installation and periods of stagnation, but also through improvements in manufacturing processes that reduce upstream emissions. The bounding approach demonstrates a viable method for considering water quality in LCA when comprehensive characterization and concentration data are not available.

Pipertzis, Achilleas;Papamokos, George;Sachnik, Oskar;Allard, Sybille;Scherf, Ullrich;Floudas, George research published 《 Ionic Conductivity in Polyfluorene-Based Diblock Copolymers Comprising Nanodomains of a Polymerized Ionic Liquid and a Solid Polymer Electrolyte Doped with LiTFSI》, the research content is summarized as follows. Diblock copolymer electrolytes based on a π-conjugated polyfluorene (PF) backbone were synthesized comprising nanodomains of a polymerized ionic liquid (PIL) and of a solid polymer electrolyte (SPE). The former consists of a single-ion conductor based on an imidazolium alkyl chain with a [Br]^– counteranion grafted on the PF backbone. The latter consists of short ethylene oxide (EO) chains, grafted on the PF backbone and further doped with LiTFSI. The two nanophases support ionic conductivity, whereas the rigid PF backbone provides the required mech. stability. In the absence of LiTFSI, ionic conductivity in the PIL nanophase is low and exhibits an Arrhenius temperature dependence. LiTFSI substitution enhances ionic conductivity by about 3 orders of magnitude and further changes to a Vogel-Fulcher-Tammann temperature dependence. However, at ambient temperature, ionic conductivity is lower than in the corresponding PEO/LiTFSI electrolytes. X-ray studies and thermal anal. revealed that the conjugated backbone imparts liquid-crystalline order that can be fine-tuned through the EO side group length. Ionic conductivity measurements performed as a function of pressure identified local jumps of [Li]⁺ and [Br]^– ions in the resp. SPE/PIL nanophases as responsible for the ionic conductivity Between the two ions, it is [Li]⁺ that has the major contribution to the ionic conductivity The current results provide designing rules for new copolymers that comprise two different ionic nanodomains (PIL and SPE) and a conjugated backbone that can further support electronic conduction.
