Enzymatic Synthesis of Cinnamic Acid Derivatives

Biotechnology Letters, 2006
Using Novozym 435 as catalyst, the syntheses of ethyl ferulate (EF) from ferulic acid (4-hydroxy 3-methoxy cinnamic acid) and ethanol, and octyl methoxycinnamate (OMC) from p-methoxycinnamic acid and 2-ethyl hexanol were successfully carried out in this study. A conversion of 87% was obtained within 2 days at 75 degrees C for the synthesis of EF.

Anticancer Agents Derived from Natural Cinnamic Acids

Anti-Cancer Agents in Medicinal Chemistry, 2015
Cancer is the most dangerous disease that causes deaths all over the world. Natural products have afforded a rich source of drugs in a number of therapeutic fields including anticancer agents. Many significant drugs have been derived from natural sources by structural optimization of natural products.

Non-natural cinnamic acid derivatives as substrates of cinnamate 4-hydroxylase

Phytochemistry, 2007
Cinnamate 4-hydroxylase (C4H), a monooxygenase in the plant phenylpropanoid pathway, was assayed for its ability to hydroxylate 29 substrate analogues. Nine of the tested analogues with various aromatic side chains, including 3-coumaric acid, were metabolized by C4H.

Antiradical activity of cinnamic acid derivatives

Pharmaceutical Chemistry Journal, 2009
The antiradical activity (ARA) of cinnamic acid derivatives and their structural analogs was evaluated by the ability to inhibit chemiluminescence in a system generating free radicals. The results showed that the ARA of the studied compounds is characterized by the same features as those established previously for the antioxidant activity of these ...

Structure of a cinnamic acid derivative

Acta Crystallographica Section C Crystal Structure Communications, 1992
C 26 H 29 NO 2 cristallise dans P2 1 2 1 2 1 avec a=9,777, b=10,211, c=22,585A, Z=4; affinement jusqu'a R=0,043. Le groupement isocyano est syn par rapport a l'atome O du carbonyl et cis par rapport au groupement phenyl. Ce phenyl forme un angle de rotation de 29° par rapport au plan du systeme conjugue π adjacent.

Cinnamic Acid Derivatives as Anticancer Agents-A Review

Current Medicinal Chemistry, 2011
Cinnamic acid and its phenolic analogues are natural substances. Chemically, in cinnamic acids the 3-phenyl acrylic acid functionality offers three main reactive sites; substitution at the phenyl ring, addition at the α,β- unsaturation and the reactions of the carboxylic acid functionality.

Synthesis of cinnamic acid-derived 4,5-dihydrooxazoles

Chemical Papers, 2013
AbstractA range of cinnamic units containing 4,5-dihydrooxazoles was prepared using two different synthetic routes. The first method was based on the transformation of substituted cinnamic or benzoic acids to 2-styryl-4,5-dihydrooxazoles. Several derivatives containing phenolic groups were prepared in this manner.
