Atm. liquefaction technol. has been used widely and is an effective way of biomass component utilization. In this paper, the liquefied products obtained from corn stalk using polyhydric alcs. 1,2-propanediol (PG) mixed diethylene glycol (DEG) through acid catalysis under atm. pressure were characterized by various anal. technologies. The results indicated that 39 kinds of organic compounds were present in bio-oil, among which alcs. were the most, phenols were the second, and their relative contents were 70.7% and 25.6%, resp. There were also some organic acids, ethers, esters, and ketones. More than 80% of these compounds had a carbon number less than 25. Carbon NMR spectra (13C-NMR) showed that different chem. shifts δ (ppm) corresponded to various carbon types. The chem. composition of the residue from liquefaction was complex and contained a certain amount of large mol. substances that were difficult to degrade. It required more severe pyrolysis conditions than those of corn stalk. Results from X-Ray Diffraction (XRD) indicated the destruction of crystalline structure of carbohydrates and the cellulose mols. were cracked, indicating that the cellulose was degraded and the degree of liquefaction was high.

A cephalexin (CEP) self-nanoemulsifying drug delivery system (SNEDDS) was developed in this study to improve the drug’s oral administration. The CEP-SNEDDS was made utilizing an aqueous titration method employing Lauroglycol 90, Poloxamer 188, and Transcutol-HP. Box-Behnken design (BBD) with three factors at three levels was used for optimization, and their impacts on globule size (nm), transmittance (percent), and emulsification time (s) were assessed. The optimized formulation (Opt-F3) was further tested for zeta potential, refractive index, percent transmittance, thermodn. stability, in-vitro release, ex vivo permeability, antibacterial activity, and bioavailability. The chosen formulation (Opt-F3) had a globule size of 87.25 ± 3.16 nm, PDI of 0.25, zeta potential of -24.37 mV, self-emulsification duration of 52 ± 1.7 s, and percentage transmittance of 99.13 ± 1.5%, viscosity of 96.26 ± 2.72 cp, and refractive index of 1.29 ± 0.1. It showed a sustained release profile (94.28 ± 5.92 percent in 24 h). The Opt-F3 formulation had 3.95 times the permeability of CEP-dispersion. In comparison to CEP-dispersion, it also demonstrated greater antibacterial efficacy against tested Gram-pos. and Gram-neg. pathogens. The oral bioavailability of Opt-F3 is 3.48 times higher than that of CEP-dispersion, according to an in-vivo investigation. It has been determined that the prepared CEP-SNEDDS may be an advantageous carrier for CEP delivery.

Zeng, Jia;Xie, Tan-Fang;Huang, Ting;Li, Fang;Wang, Zhi-Ping;Feng, Ling-Lin research published 《 Preparation and In Vitro and In Vivo Evaluation of a Testosterone Film Forming Gel for the Treatment of Hypoactive Sexual Desire Disorder in Women》, the research content is summarized as follows. Hypoactive sexual desire disorder (HSDD) is one of the most common sexual complaints in women. Currently, there is an unmet need for a drug treatment for this disorder. The purpose of this study was to develop a testosterone (TS) film forming gel used for women to treat HSDD by measuring the tackiness, peel adhesion force, tensile strength, and elasticity of the formulation. Diethylene glycol monoethyl ether (Transcutol P), an efficient penetration enhancer, was added to the optimized formulation and the transdermal permeation characteristics in vitro were studied using Franz-diffusion cells. The quant. determination of TS was performed by high-performance liquid chromatog. (HPLC). After 24 h, Transcutol P at 3% had the largest cumulative amount of drug and enhancement ratio of TS of 75.14μg/cm2 and 2.82, resp. After the screening of film forming polymers and penetration enhancers, the optimal formulation was as follows: glycerol (1%, weight/weight); 12.5% sodium CM-cellulose (CMC-Na) aqueous solution (0.5%, weight/weight); 2.5% Carbomer ethanol solution (0.5%, weight/weight); Transcutol P ethanol solution (3%, weight/weight) containing 0.5% TS; and 8% Poly vinyl alc. (PVA) aqueous solution (30%, weight/weight). The optimized film forming gel had good uniformity and the release of TS in vitro was close to 100% within 24 h. In vivo studies showed the formulations had optimal area under blood drug concentration curve values in the order of 3% Transcutol P > 1% Transcutol P > 5% Transcutol P > control preparation The formulation with 3% Transcutol P provided the highest permeation effect both in vitro and in vivo. The safety of this formulation was further evaluated with a skin irritation test. It could effectively improve the rabbit skin irritation observed with a marketed transdermal patch Androderm. The present study provides a promising approach for the development of a novel TS film forming gel for the treatment of HSDD in women.

Zeng, Lijuan;Yang, Guangqiang;Liu, Jianping;Quan, Danyi;Song, Wenting research published 《 Probing Dynamic Behavior of Chemical Enhancers Passing In and Out of the Stratum Corneum and Modulation by Biodegradable Enhancer》, the research content is summarized as follows. Chem. enhancers (CEs) decreased the barrier of the stratum corneum (SC) to enhance drug permeation. This was a ′′dynamic′′ behavior, which involved three processes including passing in, acting on, and passing out of the SC. However, compared with mature ′′static′′ researches about acting on the SC, the other two processes were poorly understood. This work aimed to probe the dynamic behavior of CEs and modulate it for satisfactory effectiveness. The investigating method of CEs′ dynamic behavior was established to obtain the rate of CEs passing in and out of the SC. An anal. attribution was conducted to obtain the possible reasons for the quite different dynamic behavior of CEs based on log P, solubility parameter, and min. binging energy. It demonstrated the rate of CEs passing in and out of the SC was dependent on CE affinity with the SC and the interaction between CEs and the SC, resp. The relevance between CEs′ dynamic behavior and the extent of decreasing SC barrier was confirmed by transepidermal water loss (TEWL). The higher rate of CE passing in the SC and a lower rate of passing out of the SC may contribute to an increased concentration of CEs in the SC, leading to a stronger ability to decrease the SC barrier. More importantly, two biodegradable CEs (Leu-Dod and Ser-Dod) of dodecanol were synthesized and achieved a modulation of its dynamic behavior to obtain more satisfactory effectiveness of enhancing drug permeation. This work was meaningful for the guidance of rationally promoting CEs′ effectiveness from a dynamic perspective, which was an unprecedented attempt in this field.

Zeng, Ruolan;Deng, Jiyong;Dang, Limin;Yu, Xinliang research published 《 Correlation between the structure and skin permeability of compounds》, the research content is summarized as follows. A three-descriptor quant. structure-activity/toxicity relationship (QSAR/QSTR) model was developed for the skin permeability of a sufficiently large data set consisting of 274 compounds, by applying support vector machine (SVM) together with genetic algorithm. The optimal SVM model possesses the coefficient of determination R² of 0.946 and root mean square (rms) error of 0.253 for the training set of 139 compounds; and a R² of 0.872 and rms of 0.302 for the test set of 135 compounds Compared with other models reported in the literature, our SVM model shows better statistical performance in a model that deals with more samples in the test set. Therefore, applying a SVM algorithm to develop a nonlinear QSAR model for skin permeability was achieved.

Zhang, Shoupeng;Xu, Xiao-Qi;Liao, Shenglong;Pan, Qianhao;Ma, Xinlei;Wang, Yapei research published 《 Controllable Degradation of Polyurethane Thermosets with Silaketal Linkages in Response to Weak Acid》, the research content is summarized as follows. Polyurethane (PU) thermosets offer great favors to our daily life on account of their excellent mech., phys., and chem. properties as well as appreciable biocompatibility. Nevertheless, PU waste is increasingly causing environmental and health-related problems as it is mostly resistant to chem. degradation under mild conditions. Herein, we report a kind of PU thermoset with silaketal leakages in its main chains to enable polymer degradation in response to weak acids, even in edible vinegar. The degradation rate is significantly influenced by the alkyl substituents on the silicon atoms, with entire degradation in hours, days, weeks, or months. Besides controllable degradation, investigations are also provided into the recycling of PU thermosets by means of thermal reprocessing based on carbamate bond exchange or repolymn. of degradation residuals. Because of the controllable degradation and easy recycling, this particular kind of PU thermoset exhibits great potential in manufacturing green polymer products that can be decomposed by nature or reutilized after disposal.

Local deliver medication in a non-invasive pattern and attaining a long-term sustained release at ocular regions to minimize side effects is fascinating for treatment and precision medicine, but its rational design remains a challenge. The aim of this study was to analyze the effect of different delivery strategies on drug bioavailability in the posterior segment of the eye. In this study, the results of mol. dynamics (MD) revealed that quercetin (QUE) and curcumin (CUR) have shown superior affinity and tighter binding capacity for the active site of vascular endothelial growth factor (VEGF). Then, developing and comparing lipid-based nanoemulsion (NE) and polymer-based nanomicelles (NM) were modified with novel mPEG-CS to achieve adequate targeting and retention. The results of in vitro biol. properties showed that nano-preparations could be successfully absorbed by cells. The result of in vivo pharmacokinetics revealed that two kinds of nano-preparations could prominently enhance the ocular bioavailability of QUE and CUR to different degrees and have a certain sustained-release effect. More importantly, the results showed that the particle size of NE was smaller than that of NM, which would make the drug retention time in the eye short and result in drug loss. Compared with NE, the release rate of NM was slower, and the effect of improving the drug bioavailability was more significant. In addition, the hydrophobic inner core-hydrophilic shell structure of NM and the carbonyl group in Soluplus material played a protective role in maintaining the stability of the drug. In summary, NM has a more significant effect on improving the ocular absorption of drugs, and is expected to become a candidate nanocarrier for non-invasive drug delivery systems and used for the treatment of post-ocular diseases.

Yang, Xinggang;Gao, Pan;Jiang, Zhujun;Luo, Qiao;Mu, Chengqiao;Cui, Mengsuo research published 《 Preparation and Evaluation of Self-emulsifying Drug Delivery System (SEDDS) of Cepharanthine》, the research content is summarized as follows. The aim of this article was to design a self-emulsifying drug delivery system (SEDDS) of loaded cepharanthine (CEP) to improve the oral bioavailability in rats. Based on the solubility determination and pseudo-ternary phase diagram, iso-Pr palmitate (IPP) was chosen as the oil phase. Meanwhile, Cremophor RH40 and Macrogol 200 (PEG 200) were chosen as the emulsifier and co-emulsifier, resp. This prescription was further optimized by using central composite design of response surface methodol. The optimized condition was CEP:IPP:Cremophor RH40:PEG 200=3.6:30.0:55.3:11.1 in mass ratio with maximum drug loading (36.21 mg/mL) and the min. particle size (36.70 nm). The constructed CEP-SEDDS was characterized by dynamic light scattering, transmission electron microscopy, in vitro release and stability studies. The dissolution level of CEP-SEDDS was nearly 100% after 30 min in phosphate-buffered saline (PBS, pH 6.8) which was higher than that of the pure CEP (approx. 20%). In addition, in vivo pharmacokinetic study in rats showed that CEP-SEDDS dramatically improved bioavailability compared with active pharmaceutical ingredient (API) (the relative bioavailability was 203.46%). In this study, CEP-SEDDS was successfully prepared to enhance the oral bioavailability which might facilitate to increase its better clin. application.

Wu, Haijun;Li, Xinlong;Zhang, Quan;Zhang, Kai;Xu, Xia;Xu, Jian research published 《 Promoting the conversion of poplar to bio-oil based on the synergistic effect of alkaline hydrogen peroxide》, the research content is summarized as follows. The synergistic catalysis effect of NaOH and H₂O₂ on the hydrothermal liquefaction (HTL) of poplar was investigated and compared to the NaOH or H₂O₂ catalyzed HTL at different temperatures and 30 min residence time. GC-MS, GPC, FT-IR, HPLC and TGA were used to comprehensively characterize the phys. and chem. properties of liquefied products (bio-oil, lignin and solid residue). The results showed that the highest total bio-oil yield (70.65%) was obtained at 280°C with NaOH (35 g/L)/H₂O₂ (30 g/L) as catalysts. The average mol. weight and polydispersity index (PDI) were found to be lower compared to that from other conditions. As the NaOH concentration was increased, the bio-oil yield was improved. The concentration of H₂O₂ for the optimal synergistic effect was observed to be 30 g/L. GC-MS anal. showed that the bio-oil obtained by NaOH (35 g/L)/H₂O₂ (30 g/L) was characterized with the lowest N content. The synergistic effect promoted the higher production selectivity of o-xylene and p-xylene in the bio-oil.
