Electrohydrodimerization of trans-cinnamaldehyde

Tetrahedron, 1997
Abstract The electrochemical reduction of trans-cinnamaldehyde in protic medium (MeOH-NaClO4) on a mercury cathode gives four cyclic hydrodimeric products in 80% yield, through a “head to tail” coupling pathway. The different anomers were identified as (±)-c-4-phenyl-t-5-[(E)-styryl]tetrahydrofuran-r-2-ol, (±)-t-4-phenyl-c-5-[(E)-styryl ...

Cinnamaldehyde Analogues as Potential Therapeutic Agents

Mini-Reviews in Medicinal Chemistry, 2016
Cinnamaldehyde analogues are a class of chemical substances originated from derivatization of cinnamaldehyde, and are structurally characterized by the presence of cinnamoyl moiety. Due to the presence of highly reactive α,α-unsaturated carbonyl pharmacophore (Michael acceptor) in their structures, these molecules are apt to react ...

Toxicokinetics of cinnamaldehyde in F344 rats

Food and Chemical Toxicology, 1992
The toxicokinetic profile of cinnamaldehyde (CNMA) was investigated in Fischer 344 rats. CNMA was found to be unstable in blood. After iv administration, a large fraction of CNMA was immediately oxidized to cinnamic acid. The biological half-life of CNMA after iv administration was found to be 1.7 hr.

Antioxidant cinnamaldehyde attenuates UVB-induced photoaging

Journal of Dermatological Science, 2019
Ultraviolet (UV) irradiation disrupts skin through several deleterious actions, such as induction of reactive oxygen species (ROS), DNA damage, and collagen degradation. Cinnamaldehyde (CIN) is a major constituent of the cinnamon and it possesses potent antioxidative activity; however, it is unclear whether CIN is capable of inhibiting the adverse ...

Investigation of urea-cinnamaldehyde resin

European Polymer Journal, 1988
Abstract The structure of the products of reaction between urea and cinnamaldehyde in acid media was studied by HET2DJ 13C NMR, 1H NMR and GPC. Two main reactions take place: the addition of urea to the carbonyl group and to the double bond. Many different oligomers wtih free carbonyl groups, double bonds, groups, -NH2 and -NH- groups are formed.

The retroaldol reaction of cinnamaldehyde

Canadian Journal of Chemistry, 1984
Rate and equilibrium constants have been measured for the hydration and retroaldol reactions of cinnamaldehyde. The equilibrium constant for the 1,4-addition of water to cinnamaldehyde is 4.42 × 10−3. The rate constants for hydroxide catalyzed reaction, extrapolated to zero hydroxide concentration (to correct for the addition of hydroxide to the aldol

Reaction of dodecacarbonyltriruthenium with cinnamaldehyde

Russian Chemical Bulletin, 1998
The reaction of dodecacarbonyltriruthenium with cinnamaldehyde yielded a mixture of the known H4Ru4(CO)12, H2Ru4(CO)13, and H2Ru6(CO)18, and Ru6C(CO)17 clusters and the 1,1,1,2,2,2,3,3,3-nonacarbonyl-1,2;1,3-(μ3-dihydrido)-1,3-σ;2-π-[μ3-η2-(pheny)vinylidene]triangulotriruthenium complex. The structure of the last-mentioned compound was established by X-

Cinnamaldehyde exerts vasculoprotective effects in hypercholestrolemic rabbits

Naunyn-Schmiedeberg's Archives of Pharmacology, 2018
The effects of cinnamaldehyde (CIN), a commonly consumed food flavor, against high-cholesterol diet (HCD)-induced vascular damage in rabbits were evaluated. Male New Zealand rabbits (n = 24) were allocated to four groups at random: control, fed with standard rabbit chow; CIN, fed with standard diet and administered CIN; HCD, fed with 1% cholesterol ...

Effects of Cinnamaldehyde on Smooth Muscle Preparations

Pharmacology, 2019
The effects of cinnamaldehyde (CNA), known as a transient receptor potential ankyrin 1 (TRPA1) agonist, on guinea-pig ileum and urinary bladder were studied in isolated organ experiments. Contractile effects were found to be present on both preparations.

Starch–lipid composites containing cinnamaldehyde

Starch - Stärke, 2011
AbstractThe formulation of a starch–lipid composite containing cinnamaldehyde as antimicrobial agent has been studied. Cinnamaldehyde was incorporated as an emulsion using acetem 90–50 K as a carrier and Tween 60 as the emulsifier. Oil in water emulsions were prepared by direct emulsification using a high shear mixer or a high pressure homogenizer ...
