A novel method for producing styrenes from trans-cinnamic acids was developed. When trans-cinnamic acid was incubated with plant cell cultures at room temperature, styrene was obtained. 4-Hydroxy-3-methoxystyrene (2a), 3-nitrostyrene (2f) and furan (2g) were synthesized quantitatively.
Cinnamic acid (CA) derivatives have recently received focus due to their anticancer, antioxidant, and antidiabetic properties. The present study aimed to determine the effects of cinnamic acid on the circadian clock, which is a cell-autonomous endogenous system that generates circadian rhythms that govern the behavior and physiology of most organisms. Cinnamic acid significantly shortened the c...
The aims of this study were to examine the bioactive component(s) responsible for the anticoagulant activity of M. malabathricum Linn. leaf hot water crude extract via bioassay-guided fractionation and to evaluate the effect of bioactive component(s) on the intrinsic blood coagulation pathway. The active anticoagulant fraction of F3 was subjected to a series of chromatographic separation and sp...
Background: The use of herbs as traditional medicine in Indonesia is increasing, with more than 40% Indonesia's population utilizing them. White oyster mushroom (Pleurotus Ostreatus) a fungus that has various therapeutic effects including antioxidant, anti-inflammatory, anti-bacterial, anti-cholesterol, and anti-cancer properties. This contains many active substa...
Cinnamic acid analogs are natural phenolic compounds that have a wide range of biological and therapeutic activities. The present work aimed to predict, through in silico methodologies, the oral bioavailability pharmacokinetic toxicological analyzes for four cinnamic analogues (caffeic acid, ferulic p-coumaric synaptic acid). study revealed good bioavailability, favorable parameters. Virtual Sc...
Ammonia-lyase activity for L-phenylalanine, m-hydroxyphenylalanine and L-tyrosine was demonstrated in cell-free extracts ofSporobolomyces roseus. Cultures of this organism converted DL-[ring-14C]phenylalanine and L-[U-14C]tyrosine into the corresponding cinnamic acid. Tracer studies showed that these compounds were further metabolized to [14C]protocatechuic acid. Benzoic acid andp-hydroxybenzoi...
Several 2,3-unsaturated carboxylic acids, such as trans-cinnamic acid and its derivatives, were found to be halogenated by chloroperoxidase of Caldariomyces fumago in the presence of hydrogen peroxide and either Cl- or Br-. Cinnamic acid, 4-hydroxycinnamic acid, 4-methoxycinnamic acid, and 3,4-dimethoxycinnamic acid were suitable substrates of chloroperoxidase, and were converted to 2-halo-3-hy...
In this study, Posidonia oceanica (L.) Delile (Posidoniaceae), which is a widely distributed phanerogam in Aegean and Mediterranean coasts, was investigated for the phenolic compounds that have the potential to be used in pharmaceutical sciences. The leaves, separated as young and mature leaves, were extracted and analyzed by high-performance liquid chromotagraphy (HPLC). The younger leaves wer...
Shikimic acid and its role in the formation of aromatic amino acids, benzoic acids, and cinnamic acids is described, along with further modifications leading to lignans and lignin, phenylpropenes, and coumarins. Combinations of the shikimate pathway and the acetate pathway are responsible for the biosynthesis of styrylpyrones, flavonoids and stilbenes, flavonolignans, and isoflavonoids. Terpeno...
The paper reports the isolation and characterization of β-sitosterol, t-cinnamic acid [undecyl (E)-3-(4hydroxyphenyl)-2-propenoate], an unknown coumarin and a lignan type resin glycoside from the tuberous roots of Ipomoea digitata. The structures of the compounds were elucidated on the basis of extensive chemical and spectroscopic data. Importantly, one of the compounds exhibited significant an...
