Maddala, Sudhakar;Panua, Anirban;Venkatakrishnan, Parthasarathy research published 《 Steering Scholl Oxidative Heterocoupling by Tuning Topology and Electronics for Building Thiananographenes and Their Functional N-/C-Congeners》, the research content is summarized as follows. This report systematically demonstrates how topol. variation of electronics and reactivity in thiophene substrates can lead to efficient oxidative heterocoupling. Bis(biaryl)thiophenes having reactive α- and β-positions open are the choice of substrates. The cyclizing arene partners are so electronically tuned for thiophene’s reactivity (at α- and β-) as to establish C-C bond oxidatively generating sym. as well as unsym. diphenanthrothiophenes which are basic thiananographenes. Depending on the cyclizing-couple’s electronics, either arene- or thiophene-centered oxidation initiates C-C heterocoupling. The potential utility of these simple thiananographenes is further unfurled by converting them to functional N-/C-graphene segments that are aza-corannulene precursor and tetrabenzospirobifluorene. Their bright emission and extended electrochem. stability are remarkable that may be potentially important and applicable.

Ma, Yan;Wang, Pei;Gu, Zhenxin;Sun, Maomao;Yang, Runqiang research published 《 Effects of germination on physio-biochemical metabolism and phenolic acids of soybean seeds》, the research content is summarized as follows. In this study, changes of phenolic acids and antioxidant capacity during germination of soybean seeds were investigated. Results revealed that germination enhanced sprout growth, changed endogenous phytohormones level and caused oxidative damage, but enhanced phenolic acids accumulation. Eight individual phenolic acids in soybean sprouts were identified by HPLC. Gallic acid and protocatechuic acid mainly present in free form, while vanillic acid mainly present in bound form, and p-hydroxybenzoic acid, syringic acid, p-coumaric acid, ferulic acid and sinapic acid were both identified in free and bound phenolic extracts Both free and bound phenolic acids contents significantly increased during germination. The enzymes activities of phenylalanine ammonia lyase (PAL), cinnamic acid 4-hydroxylase (C4H) and 4-coumarate CoA ligase (4CL) that participated in the biosynthesis of phenolic acids were up-regulated. These results contribute to the further insights into the health-promoting compounds of soybean sprouts.

Safety of 3,5-Dimethoxy-4-hydroxycinnamic acid, Sinapinic acid is a chemical compound that is the dihydroxybenzoic acid derivative of sinapic acid. It has been shown to have anti-inflammatory properties in vitro and in vivo. Sinapinic acid inhibits the activity of various enzymes, such as cyclooxygenase (COX), lipoxygenase (LOX), and 5-lipoxygenase-activating protein (FLAP).

It scavenges 2,2-diphenyl-1-picrylhydrazyl (DPPH; ) and 2,2′-azino-bis-(3-ethylbenzothiazoline-6-sulfonate) (ABTS) free radicals with IC50 values of 8.3 and 5.4 μg/ml, respectively. Sinapic acid (200 μM) reduces colony formation of SW480 human colon carcinoma cells by 4-fold. It also inhibits colony formation of E. coli, S. enteritidis, and S. aureus on agar (MICs = 2.2, 2, and 1.8 mM, respectively). In vivo, sinapic acid (4 mg/kg, p.o.) increases the time spent in the open arms of the elevated plus maze by approximately 15% in mice, an effect that can be blocked by the GABAA receptor antagonists flumazenil and bicuculline. Sinapic acid is also commonly used as a matrix in protein mass spectrometry.

Sinapic acid is an hydroxycinnamic acid derivative that occurs naturally in Brassicaceae species.
cis-Sinapic acid, also known as cis-sinapate or synapitic acid, belongs to the class of organic compounds known as hydroxycinnamic acids. Hydroxycinnamic acids are compounds containing an cinnamic acid where the benzene ring is hydroxylated. cis-Sinapic acid is considered to be a practically insoluble (in water) and relatively neutral molecule. Within the cell, cis-sinapic acid is primarily located in the cytoplasm. Outside of the human body, cis-sinapic acid can be found in common pea and pulses. This makes cis-sinapic acid a potential biomarker for the consumption of these food products.

Ma, Qiuyan;Zhang, Jing;Lu, Bohong;Lin, Huaqing;Sarkar, Rajib;Wu, Tao;Li, Xuee research published 《 Nanoemulgel for Improved Topical Delivery of Desonide: Formulation Design and Characterization》, the research content is summarized as follows. This research aimed to develop a novel drug delivery system to improve treatment of skin disorders. The system is comprised of a Carbopol 980-based nanoemulgel (NE-gel) containing a desonide (DES; 0.05%, weight/weight) nanoemulsion (NE), which has a small particle size, high encapsulation efficiency, good thermodn. stability, good permeation ability, and high skin retention. DES-loaded NE (DES-NE) was prepared by high-pressure homogenization. The developed formulation was characterized by differential scanning calorimetry (DSC), X-ray diffraction, drug release, skin permeation, and drug retention. DES in vitro release and skin permeation studies with different formulations of artificial membrane and rat abdominal skin were performed with the Franz diffusion cell system. Confocal laser scanning microscopy (CLSM) was used to detect the localization and permeation pathways of drugs in the skin. Compared with com. available gel (CA-gel) and NE, the NE-gel release process conformed to the Higuchi release model (R2 = 0.9813). NE-gel prolonged the drug release time and allowed for reduced administration dose and frequency. The unit cumulative permeation of NE and NE-gel through the skin for 12 h was 63.13 ± 2.78 and 42.53 ± 2.06μg/cm², resp., values significantly higher (p < 0.01) than that of the CA-gel (30.65 ± 1.25μg/cm²) and CA-cream (15.21 ± 0.97μg/cm²). The DES-NE and DES NE-gel skin drug retention was significantly higher than com. available formulations (p < 0.01). Hence, the prepared NE-gel is a potential vehicle for improved topical DES delivery for better treatment of skin disorders.

Luo, Zheng;Liu, Chao;Quan, Peng;Zhang, Yimeng;Fang, Liang research published 《 Effect of Chemical Penetration Enhancer-Adhesive Interaction on Drug Release from Transdermal Patch: Mechanism Study Based on FT-IR Spectroscopy, ¹³C NMR Spectroscopy, and Molecular Simulation》, the research content is summarized as follows. Chem. penetration enhancers (CPEs) are commonly added into transdermal patches to impart improved skin permeation of drug. However, significant unexplained variability in drug release kinetics in transdermal patches is possible as a result of the addition of CPEs; investigations into the underlying mechanisms are still limited. In the present study, a diverse set of CPEs was employed to draw broad conclusions. Solubility parameters of CPEs and acrylate pressure-sensitive adhesive were calculated by mol. dynamics simulation and Fedors group contribution method to evaluate drug-adhesive miscibility. CPE-adhesive interaction was characterized by FT-IR study, ¹³C NMR spectroscopy, and mol. docking simulation. Results showed that release enhancement ratio (ERR) of CPEs for zolmitriptan was rank ordered as iso-Pr myristate > azone > Plurol Oleique CC497 > Span 80 > N-methylpyrrolidone > Transcutol P. It was found that solubility parameter difference (Δδ) between CPE and adhesive was neg. related with ERR. It was proved that hydrogen bonding between CPE and adhesive would increase drug release rate, but only if the CPE showed good miscibility with adhesive. CPE like iso-Pr myristate, which had good miscibility with adhesive, could decrease drug-adhesive interaction leading to the release of drug from adhesive.
