Ethers do have nonbonding electron pairs on their oxygen atoms, 530-59-6, formula is C11H12O5, Name is 3,5-Dimethoxy-4-hydroxycinnamic acid. The ability to form hydrogen bonds with other compounds makes ethers particularly good solvents for a wide variety of organic compounds and a surprisingly large number of inorganic compounds. Name: 3,5-Dimethoxy-4-hydroxycinnamic acid.
Skiba, Margarita;Vorobyova, Victoria research published 《 Green synthesis and characterization of silver nanoparticles using Prunus persica L. (peach pomace) with natural deep eutectic solvent and plasma-liquid process》, the research content is summarized as follows. This study reports two different innovation “green” protocols for the extraction of fruit waste peach pomace (PP) and subsequent synthesis of silver nanoparticles that were used. In one case, extraction of PP was performed using natural ionic solvent (lactic acid, glucose, and water (5:1:3 molar ratio)) with the following chem. synthesis of the AgNPs in the second step. In the second case, a one-step extraction/synthesis of silver nanoparticles under a short-term (5-10 min) plasma-liquid atm. discharge process was used. Various techniques used to characterize synthesized nanoparticles are SAED, SEM, TEM, and UV-visible spectrophotometer. It was found that for both methods, the hydromodule (ratio of raw materials to solvent) is one of the main factors that determines the absorption spectra and particle size of the synthesized AgNPs. The simultaneously plasma chem.-assisted extraction and synthesis NPs protocol with hydromodule ∼ [1]:[10] ÷ [1]:[60] provides the formation surface plasmon resonance (SPR) of absorption spectra at 420-430 nm with average size of NPs 15-27 nm for 1 min of processing; λmax = 550-570 nm, λmax = 670 nm with average size of NPs 100-150 nm. NADES-assisted extraction and synthesis NPs with hydromodule ∼ [1]:[20] ÷ [1]:[45] provides SPR at 405-430 nm with average size of NPs 10-20 nm. It was established that plasma-assisted extraction provides a greater degree of extraction total phenolic content (TPC) compared to NADES extraction As a consequence, it provides correspondingly higher indicators of antioxidant activity of plasma-synthesized silver nanoparticles (IC50 of 0.81-1.33 mg/mL, DPPH at 2.5 mg/mL was: 73-88% for AgNPs). In return NADES extraction provides higher antimicrobial and catalytic activity of the AgNPs because they are depended by the average size of nanoparticles, which are much smaller in the synthesis of this method. The AgNPs showed antimicrobial activity against pathogenic Escherichia coli, Staphylococcus aureus, and Candida albicans antimicrobial activity in low concentrations (23-36 nM).
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., Name: 3,5-Dimethoxy-4-hydroxycinnamic acid
