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.

A series of 2-phenylthiazole analogs I (R = 3,4,5-trimethoxyphenyl, naphthalen-2-yl, 2-fluorophenyl, etc.; n = 1, 2, 3, 4, 5, 6), II (R¹ = anthracen-9-yl, 1H-indol-6-yl, 4-chlorophenyl, etc.; R² = OH, 2-aminophenyl) were designed and synthesized as potential histone deacetylase 6 (HDAC6) inhibitors based on an HDAC6/tubulin dual inhibitor discovered recently and CAY10603 (a known HDAC6 inhibitor). Among them, compound I [R = 2,3-dimethoxyphenyl, n = 6 (III)] was the most potent HDAC6 inhibitor with an IC₅₀ of 31 nM and excellent HDAC6 selectivity (SI = 338 for HDAC6 over HDAC3). Compound III also displayed high antiproliferative activity against various cancer cell lines including the HDACi-resistant YCC3/7 gastric cancer cells (IC₅₀ = 0.16-2.31μM), better than CAY10603. Further, compound III (50 mg/kg) exhibited significant antitumor efficacy in a melanoma tumor model with a tumor growth inhibition (TGI) of 63% without apparent toxicity. Moreover, compound III efficiently enhanced the in vivo antitumor immune response when combined with a small-mol. PD-L1 inhibitor, as demonstrated by the increased tumor-infiltrating lymphocytes and reduced PD-L1 expression levels. The above results suggest that compound III is a promising HDAC6 inhibitor deserving further investigation.

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.

Pico, Joana;Yan, Yifan;Gerbrandt, Eric M.;Castellarin, Simone D. research published 《 Determination of free and bound phenolics in northern highbush blueberries by a validated HPLC/QTOF methodology》, the research content is summarized as follows. Blueberry consumption has increased in recent years, partially due to the health benefits attributed to their phenolic content. This study aimed to optimize and validate a high-performance liquid chromatog./quadrupole-time of flight mass spectrometry (HPLC/QTOF-MS) methodol. for the determination of free (i.e., solvent extractable) and bound (i.e., covalently bound to the plant cellular structures) phenolics in northern highbush blueberries. A total of 31 phenolics, including anthocyanins, flavonols, flavan-3-ols, and phenolic acids, were targeted in the pos. electrospray ionization mode [ESI (+)], including MS/MS confirmation of their product ions. Free phenolics determination was validated in terms of sensitivity, reproducibility, linearity, and accuracy, and 21 free phenolic compounds were found above their limits of detection among six com. blueberry cultivars, which were quantified with correction for the matrix effect. ‘Elliott’ presented the highest free phenolic and anthocyanin contents (3640 and 3430 mg kg^-1 fresh weight, resp.). Malvidin-3-O-galactoside was the most abundant free phenolic for ‘Duke’, ‘Draper’, ‘Elliott’, and ‘Last Call’ while chlorogenic acid predominated for ‘Bluecrop’ and ‘Calypso’. Syringetin-3-O-glucoside was the most abundant bound phenolic compound among the six blueberry cultivars.

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.

Pires, Patricia C.;Fazendeiro, Ana C.;Rodrigues, Marcio;Alves, Gilberto;Santos, Adriana O. research published 《 Nose-to-brain delivery of phenytoin and its hydrophilic prodrug fosphenytoin combined in a microemulsion – formulation development and in vivo pharmacokinetics.》, the research content is summarized as follows. Phenytoin is a low aqueous solubility antiepileptic drug, but its phosphate ester prodrug fosphenytoin is soluble, although less permeable. In a previous study, the intranasal administration of aqueous-based formulations of fosphenytoin led to high but delayed phenytoin bioavailability compared to the i.v. route. In this work, we hypothesized that formulating an association of the prodrug fosphenytoin and the drug phenytoin (the active and diffusible form), could result in a faster and/or more effective brain targeting. Hence, nano or microemulsions containing both active drug and prodrug were developed and characterized regarding viscosity, osmolality, pH, mean size and in vitro drug release. Then, in vivo pharmacokinetics of a selected microemulsion containing fosphenytoin and phenytoin was evaluated in mice following intranasal administration and compared with a similar microemulsion containing fosphenytoin only. Both microemulsions led to higher brain drug levels at short time points than previously developed simpler aqueous based fosphenytoin formulations, likely due to the microemulsion′s permeation enhancing effect. In addition, having a small amount of phenytoin in the formulation led to an equivalent maximum brain drug concentration and an overall higher absolute bioavailability, with a prolonged drug exposure. Hence, it can be concluded that if there is a need for a fast and prolonged therapeutic effect, a drug/phosphate ester prodrug combination in a microemulsion is ideal, but if a fast effect is all that is needed, having the prodrug alone could be enough, while considering a formulation with permeation enhancing components.
