TRANS‐CINNAMIC ACID AS AN ANTI‐AUXIN

American Journal of Botany, 1951
IT IS WELL RECOGNIZED at present that the vast majority of compounds which display auxin activity have a distinct molecular configuration (recent summaries by Thimann, 1951; van Overbeek, 1950). Among these requirements is a rather specific steric relationship regarding the position of the side chain relative to the ring.

Sheep scab control using trans-cinnamic acid

Veterinary Parasitology, 2011
A series of in vitro and in vivo assays were conducted to examine the effects of trans-cinnamic acid ethyl ester on Psoroptes mange mites. In vitro, 24h after exposure to the test material at concentrations of 10, 1 or 0.1% (v/v), 100, 74 and 20% of mites had died, respectively, compared to 8% following exposure to the control (0.05% SDS only).

A spectrophotometric assay for trans-cinnamic acid 4-hydroxylase activity

Analytical Biochemistry, 1975
trans-Cinnamic acid 4-hydroxylase (trans-cinnamic acid, NADPH: oxygen oxidoreductase [4-hydroxylating]) can be rapidly and precisely assayed by the spectrophotometric measurement of the production of 4-hydroxy-trans-cinnamic acid at 340 nm after acidification of the reaction mixture and subsequent readjustment to pH 11.

Vacuolar transport of the glutathione conjugate of trans-cinnamic acid

Phytochemistry, 2000
Red beet (Beta vulgaris L.) tonoplast membrane vesicles and [14C]trans-cinnamic acid-glutatione were used to study the vacuolar transport of phynylpropanoid-glutathione conjugates which are formed in peroxidase-mediated reactions. It was determined that the uptake of [14C]trans-cinnamic acid-glutathione into the tonoplast membrane vesicles was MgATP ...

Complexation of Oleuropein and trans-Cinnamic Acid with Cyclodextrins

Chemistry of Natural Compounds, 2004
The complexation of oleuropein and trans-cinnamic acid with α-, β-, and γ-cyclodextrin has been studied in aqueous model systems by light scaterring. The influence of various parameters (pH, concentration, reaction time, nature of cyclodextrin) has been thoroughly examined.

Synthesis and antimycobacterial evaluation of new trans-cinnamic acid hydrazide derivatives

Bioorganic & Medicinal Chemistry Letters, 2008
In this work, we report the synthesis and the antimycobacterial evaluation of new trans-cinnamic acid derivatives of isonicotinic acid series (5) and benzoic acid series (6), designed by exploring the molecular hybridization approach between isoniazid (1) and trans-cinnamic acid derivative (3).

Time-resolved electron paramagnetic resonance study of the lowest excited triplet states of trans-cinnamic acid and trans-cinnamate anion

Chemical Physics Letters, 1997
Abstract Time-resolved and steady-state electron paramagnetic resonance spectra have been observed for the lowest excited triplet (T 1 ) states of trans-cinnamic acid (RCOOH) and trans-cinnamate anion (RCOO − ) in methanol-water and in stretched poly(vinyl alcohol) films at 77 K.

Chlorination of αβ-unsaturated carbonyl compounds. Part III. Reaction of chlorine with trans-cinnamic acid and the trans-cinnamate ion

J. Chem. Soc. B, 1968
The addition of chlorine to trans-cinnamic acid in acetic acid and in acetic acid containing lithium chloride, lithium perchlorate, or perchloric acid is very similar to that observed for methyl trans-cinnamate. A similar mixed mechanism, involving a direct addition of chlorine and collapse of, and reaction of the solvent with, an ion-pair and ...

Structure–activity relationships of trans-cinnamic acid derivatives on α-glucosidase inhibition

Bioorganic & Medicinal Chemistry Letters, 2004
trans-Cinnamic acid and its derivatives were investigated for the alpha-glucosidase inhibitory activity. 4-Methoxy-trans-cinnamic acid and 4-methoxy-trans-cinnamic acid ethyl ester showed the highest potent inhibitory activity among those of trans-cinnamic acid derivatives.
