Ethers lack the hydroxyl groups of alcohols. Without the strongly polarized O―H bond, ether molecules cannot engage in hydrogen bonding with each other. 530-59-6, formula is C11H12O5, Name is 3,5-Dimethoxy-4-hydroxycinnamic acid. Ethers do have nonbonding electron pairs on their oxygen atoms, however, and they can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds.

Sun, Yanhua;Yao, Chuan;Zeng, Junliang;Zhang, Yuxiang;Zhang, Yange research published 《 Eco-friendly deep eutectic solvents skeleton patterned molecularly imprinted polymers for the separation of sinapic acid from agricultural wastes》, the research content is summarized as follows. A new and facile sinapic acid imprinted polymer coated hydroxyapatite based on deep eutectic solvents (DESs) was prepared and applied as an adsorbent material to selectively extract sinapic acid from squeezed rape seed extract Different DESs acted as functional monomers and cross-linkers in preparing MIPs. Hydroxyapatite was selected as the core and the imprinting layer was coated evenly on its surface. Batch adsorption tests indicated that the MIPs displayed superior recognition ability by possessing an adsorption capacity of 121 mg g-1. The prepared imprinted materials could be regeneratively and repeatedly used without a significant reduction in adsorption capacity. The abovementioned good performances caused the proposed method to be further applied for the selective extraction of sinapic acid in squeezed rape seed extract Compared with the previous extraction methods, the facile and eco-friendly method proposed in this work could simultaneously settle the issues “residues of toxic organic solvent” and “lack of specificity and selectivity”. Therefore, the proposed approach would provide a good candidate for the extraction of active ingredients from agricultural wastes.
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., Related Products of 530-59-6
