New Caffeic Acid Esters from Plazia daphnoides

New caffeic acid esters from Plazia daphnoides.

Two new 3,4 dihydroxycinnamic acid esters have been isolated from Plazia daphnoides. The structures were elucidated by NMR spectroscopy.

Electrochemical behaviour of new dimeric esters and amides derived from caffeic acid in dimethylsulfoxide.

The electrochemical oxidation in DMSO of four new derivatives of caffeic acid (CA), two dimeric amides and two dimeric esters, is reported in this article. Although all of them contain two caffeoyl electroactive moieties in their structures, small differences in the connectors result in interesting changes in the electrochemical behaviour of this type of compound. Voltammograms of both esters d...

synthesis of heterocyclic esters of caffeic acid using mitsunobu reaction

Synthesis, Evaluation of Anticancer Activity and QSAR Study of Heterocyclic Esters of Caffeic Acid

 Caffeic acid phenethyl ester(CAPE) suppresses the growth of transformed cells such as human breast cancer cells, hepatocarcinoma , myeloid leukemia, colorectal cancer cells, fibrosarcoma, glioma and melanoma. A group of heterocyclic esters of caffeic acid was synthesized using Mitsunobu reaction and the esters were subjected to further structural modification by electrooxidation of the catecho...

Caffeic acid derivative from Clinopodium umbrosum

Background and objectives: Plants of genus Clinopodium have been used in different cultures as traditional medicines.Due to theimportance of medicinal properties of the genus Clinopodium, C. umbrosum was selected for phytochemical analysis along with evaluation of its antioxidant property. Methods: The aerial parts of C. umbrosum<...
