Choi, Hoo-kyun;Acharya, Gayathri;Lee, Yugyung;Lee, Chi H. research published 《 A Data-Mining Approach for the Quantitative Assessment of Physicochemical Properties of Molecular Compounds in the Skin Flux》, the research content is summarized as follows. This paper aimed to provide an insight into the mechanism of transdermal penetration of drug mols. with respect to their physicochem. properties, such as solubility (S), the presence of enantiomer (ET) and logarithm of octanol-water partition coefficient (log P), mol. weight (MW), and m.p. (MP). Propionic acid derivatives were evaluated for their flux through full-thickness skin excised from hairless mice upon being delivered from silicone-based pressure-sensitive adhesive (PSA) matrixes in the presence or absence of various enhancers. The skin fluxes of model compounds were calculated based on the data obtained using the method engaged with the diffusion cell system. The statistical design of experiments (DoE) based on the factorial approach was used to find variables that have a significant impact on the outcomes. For the prediction of skin flux, a quant. equation was derived using the data-mining approach on the relationship between skin permeation of model compounds (∼125 mg/mL) and involved physicochem. variables. The most influential variables for the skin flux of propionic acid derivatives were the m.p. (0.97) followed by the presence of enantiomer (0.95), mol. mass (0.93), log P values (0.86), and aqueous solubility (0.80). It was concluded that the skin flux of mol. compounds can be predicted based on the relationship between their physicochem. properties and the interaction with cofactors including additives and enhancers in the vehicles.

The occurrence and manipulation of supramol. chirality in deep eutectic solvents (DESs) was explored. Transfer from inherent chiral DES to solutes in either aggregated or monomeric building units is blocked. The chiral assembly of π-conjugated amino acids was realized. Compared to aqueous media, self-assembly in DES hinders the spontaneous structural and chirality evolution that benefit from efficient solvation, where the π-conjugated amino acids were involved as H bonding donors. DES performs as a dye-friendly matrix to afford chiroptical eutectogels with tunable circularly polarized luminescence, whereby a large dissymmetry g-factor of ≤0.015 was realized. DES behaves as feasible and flexible solvents to fabricate and stabilize functional soft chiral self-assemblies with controllable chiroptical properties.

Chen, Xiaolin;Bai, Xianglan research published 《 Co-conversion of wood and polyvinyl chloride to valuable chemicals and high-quality solid fuel》, the research content is summarized as follows. Polyvinyl chloride (PVC)-containing waste streams are difficult to recycle due to high chlorine content in PVC. Toxic dioxins or corrosive hydrogen chloride (HCl) vapor released from improper management of PVC-containing wastes can cause severe environmental pollution and human health problems. While PVC is usually treated as contamination and burden in waste recycling, a novel recycling approach was developed in this study to leverage PVC as an asset. Specifically, red oak and PVC were co-converted in γ-valerolactone, a green biomass-derivable solvent. During the co-conversion, PVC-derived HCl in the solvent acted as an acid catalyst to produce up to 14.4% levoglucosenone and 14.3% furfural from red oak. On the other hand, dechlorinated PVC hydrocarbons and lignin fraction of red oak reacted each other to form chlorine-free solid fuels with high thermal stability. The higher heating value of the solids was up to 36.2 MJ/kg, which is even higher than the heating value of anthracite coal. After the co-conversion, more than 80% of PVC-contained chlorine turned into chloride ion and the rest formed 5-chlorovaleric acid. 5-chlorovaleric acid crystals were further recovered from the post-reaction liquid with a purity of 91.2%.

Chen, Wang;Feng, Zili;Hu, Daihua;Meng, Jin research published 《 Design and Synthesis of Arylnaphthalene Lignan Lactone Derivatives as Potent Topoisomerase Inhibitors》, the research content is summarized as follows. Arylnaphthalene lignan lactones are a class of natural products containing the phenyl-naphthyl skeleton. Some arylnaphthalene lignan lactones have been used in clin. practice as antitumor agents, due to their cytotoxicity and inhibitory activities against DNA topoisomerase I (Topo I) and topoisomerase II (Topo II). This study presents the design and synthesis of arylnaphthalene lignan lactones derivatives The inhibitory activities against Topo I and Topo IIα and antitumor activities of these compounds were assayed. A series of arylnaphthalene lignan lactones derivatives have been designed and synthesized, using the Diels-Alder reaction and Suzuki reaction as the key steps. Their antiproliferation activities were evaluated by sulforhodamine B assay on human breast cancer MDAMB-231, MDA-MB-435 and human cervical cancer HeLa cells. DNA relaxation assays were employed to examine the inhibitory activity of compounds 1-22 on Topo I and Topo IIα in vitro. Flow cytometry anal. was performed to study the drug effects on cell cycle progressions. Seven compounds exhibited the modest anti-proliferation activity with IC50 values between 1.36 and 20 μM. Compounds 3, 19 and 22 showed potent inhibitory activities with IC50 values less than 1 μM. DNA relaxation assay revealed that compound 22 showed potent inhibitory activity against Topo IIα in vitro. Compound 22 also induced DNA breaks in MDA-MB-435 cells evidenced by comet tails and the accumulation of γ-H2AX foci. The ability of 22 in inducing DNA breaks mediated by Topo IIα resulted in G2/M phase arrest and apoptosis. This work indicates that arylnaphthalene lignan lactones derivatives represent a novel type of Topo IIα inhibitory scaffold for developing new antitumor chemotherapeutic agents.

Electric Literature of 530-59-6, 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 also decreases levels of adhesion molecules and downregulates inflammatory response genes. Sinapinic acid has been shown to reduce inflammation by inhibiting the formation of proinflammatory mediators, such as prostaglandin E2 or leukotriene B4, in endothelial cells and mammary epithelial cells.
Sinapic acid is a phenylpropanoid hydroxycinnamic acid with diverse biological activities. Sinapic acid inhibits collagen-induced human platelet aggregation by up to 70% in vitro (IC50 = 1.03 mM). 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 analytical standard provided with w/w absolute assay, to be used for quantitative titration.
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.
Cis-sinapic acid is a 3-(4-hydroxy-3,5-dimethoxyphenyl)prop-2-enoic acid in which the double bond has cis-configuration. It has been isolated from the shoots of alfalfa. It has a role as a plant metabolite., 530-59-6.

Chen, Jia;Zhang, Lingyan;Li, Qi;Gao, Yuan;Yu, Xiuzhu research published 《 Utilization of Diaphragma juglandis extract as a natural antioxidant for improving the oxidative stability of soybean oil during deep frying》, the research content is summarized as follows. Lipid oxidation significantly shortens the life of frying oils, and this challenge can be addressed by using antioxidants. This work aimed to investigate the effect of Diaphragma juglandis extract (DJE) on the oxidative stability of soybean oil during deep frying. Tert-butylhydroquinone (TBHQ) and tea polyphenol (TP) were applied as pos. controls. A total of 31 polyphenols were determined in DJE, and catechin, quercitrin, taxifolin, quercetin 3-β-d-glucoside, epicatechin, gallic acid, and 3,4-dihydroxybenzoic acid were the main components. The antioxidants effectively delayed the degradation of triglycerides and inhibited the increase in the contents of p-anisidine, oxidized triglyceride monomers, triglyceride dimers, and triglyceride oligomers, with DJE exhibiting better performance. Moreover, DJE showed better inhibitory effect on the formation of (E)-2-alkenals, (E,E)-2,4-alkadienals, 4-oxo-alkanals, primary alcs., and secondary alcs. detected by 1H NMR than TBHQ and TP. Therefore, DJE has great potential as an excellent antioxidant in large-scale industrial applications.

Chen, Hao;Mao, Runyu;Brzozowski, Martin;Nguyen, Nghi H.;Sleebs, Brad E. research published 《 Late stage phosphotyrosine mimetic functionalization of peptides employing metallaphotoredox catalysis》, the research content is summarized as follows. Access to phosphotyrosine (pTyr) mimetics requires multistep syntheses, and therefore late stage incorporation of these mimetics into peptides is not feasible. Here, we develop and employ metallaphotoredox catalysis using 4-halogenated phenylalanine to afford a variety of protected pTyr mimetics in one step. This methodol. was shown to be tolerant of common protecting groups and applicable to the late stage pTyr mimetic modification of protected and unprotected peptides, and peptides of biol. relevance.
