Ethers can again be classified into two varieties: if the alkyl or aryl groups are the same on both sides of the oxygen atom, 530-59-6, formula is C11H12O5, Name is 3,5-Dimethoxy-4-hydroxycinnamic acid. Then it is a simple or symmetrical ether, whereas if they are different, the ethers are called mixed or unsymmetrical ethers. HPLC of Formula: 530-59-6.
Khan, Palwasha;Akhtar, Naveed research published 《 Phytochemical investigations and development of ethosomal gel with Brassica oleraceae L. (Brassicaceae) extract: An innovative nano approach towards cosmetic and pharmaceutical industry》, the research content is summarized as follows. The study was aimed to develop and characterize plant extract (Brassica oleraceae) loaded ethosomal gel for the valuation of cosmeceutical applications with a credence that botanical extracts have a greater capability to be employed in the formulation of advanced pharmaceuticals. Phytochem. profiling via FT-IR anal., total bioactive contents of different polarity extracts (ethanol, dichloromethane, ethyl-acetate and chloroform) and quantification by using High Performance Liquid Chromatog. (HPLC) assay was carried out. Capabilities against oxidative stress were prodded through 2, 2-Diphenyl-1-picrylhydrazyl (DPPH), reduction potential analyses. Besides this, a correlation amongst total bioactive contents (TPC/TFC) and antioxidant potentials (biol. activities) was studied by multi-variate statistical anal. An augmented ethosomal preparation, after characterization and stability studies was incorporated to the gel matrix of Carbopol-940; Test/ EG (Ethosomal gel) with a Control/NEG (Non-ethosomal gel) formulation. Both formulations were then subjected to in-vitro characterization (organoleptic evaluation, pH, conductivity and rheol.) of 90 days. By permeation studies flux (μg/cm2/h); enhancement ratio was calculated and characterization of release data was done by using different kinetic models. The plant extracts revealed the presence of different functional groups along with 39.6 ± 0.5 mgGAE/g; 26.56 ± 0.4 mgQE/g phenolic and flavonoid contents, resp.; HPLC assay confirmed the existence of Quercetin, Gallic, Caffiec, Benzoic, Syringic and Sinapic Acids with highest antioxidant activity of 87.75% ± 1.18 in hydro-alc. fraction. Optimized ethosomal formulation exhibited entrapment efficiency of 68.57 ± 1.25, smallest vesicle size of 228.6 ± 1.17 nm with – 21.3 ± 0.15, zeta potential and a homogeneous size distribution of 0.233 ± 0.02. Significant results were obtained after in-vitro characterization. Both formulations followed Korsmeyer-peppas model with flux 35.499 and 21.731μg/cm2/h resp. and enhancement ratio 1.63. Thus, a stable ethosomal loaded gel of Brassica oleraceae extract was successfully developed and characterized for cosmeceutical potential.
HPLC of Formula: 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.
