Ethers feature bent C–O–C linkages. In dimethyl ether, the bond angle is 111° and C–O distances are 141 pm. 530-59-6, formula is C11H12O5, Name is 3,5-Dimethoxy-4-hydroxycinnamic acid. The barrier to rotation about the C–O bonds is low. The bonding of oxygen in ethers, alcohols, and water is similar. In the language of valence bond theory, the hybridization at oxygen is sp3.

Renovascular hypertension is defined as the reduction in renal perfusion resulting in sustained hypertension. This study aims to investigate the possible effects of myrtle leaf extract (Myrtus communis L.) on, heart, kidney and aorta tissues in the exptl. renovascular hypertension (RVH). 32 male Wistar Albino rats were divided into four groups as control, hypertension, hypertension+ramipril, and hypertension+myrtle leaf extract treatment groups. RVH model was induced by Goldblatts 2-kidney 1-clip method. 12 wk later than the treatment blood pressures were recorded and oxidant and antioxidant parameters, tissue factor activity, and histol. anal. were determined in the kidney, heart, and aortic tissues. The blood pressure levels of the hypertension group significantly increased compared to the control group. Administration of myrtle leaf extract and ramipril significantly decreased the increased blood pressure. In the hypertension group, oxidative damage increased in the kidney, heart, and aorta tissues. In the histol. evaluation of tissues in RVH, heart muscle fibers degenerated. Bowman capsule and glomeruli dilated and tubules damaged in the kidney. Myrtle leaf extract administration regenerated the damages and degenerations. The administration of myrtle leaf extract restored the impaired oxidant-antioxidant balance in the heart, kidney and aorta tissues of hypertensive rats. Myrtle leaf extract can be considered as an alternative antihypertensive treatment target in the prevention of oxidative stress-induced damage in renovascular hypertension.
Quality Control 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.
