CLA is a generic term describing different isomers of linoleic acid with two conjugated double bonds. Various metabolic effects have been demonstrated following administration of CLA, including a change in body composition in animals. However, the effects of pure CLA isomers are not fully understood. In addition, conjugated octadecatrienoic acids such as calendic acid have not been extensively investigated. In this study, male and female ICR mice were fed pure CLA isomers (cis9,trans11 or trans10,cis12) or calendic acid (trans8,trans10,cis12) as their ethyl esters for 6 wk. Body protein content was significantly increased after feeding CLA isomers, either as pure isomers or as a mixture. Calendic acid significantly decreased body fat content in males. CLA (pure isomers or a mixture) significantly decreased body fat in both males and females, with the trans10,cis12 isomer being the most effective. The effect of the cis9,trans11 isomer was more pronounced in females than in males. It was concluded that the trans10,cis12 CLA isomer was mainly responsible for the decrease in fat content in mice, without a significant modification of feed efficiency, and that it was more effective than calendic acid.

Calendic acid (CA) is a conjugated fatty acid with anti-cancer properties that is widely present in seed oil of . Using the co-expression of fatty acid conjugases (CoFADX-1 or CoFADX-2) and fatty acid desaturase (PgFAD2), we metabolically engineered the synthesis of CA in the yeast without the need for linoleic acid (LA) supplementation. The highest CA titer and achieved accumulation were 4.

Conjugated fatty acids (CFAs) including both conjugated linoleic acids (CLAs) and conjugated linolenic acids (CLNAs) have various health promoting effects. These beneficial effects are comprised by their antioxidant, antiatherogenecity, anticarcinogenic activities, etc. Several reports indicate that CLNAs such as eleostearic acid, punicic acid, jacaric acid, and calendic acid possess anticancer properties.

There are many reports of the anti-inflammatory, anti-cancer, and anti-atherosclerotic activities of conjugated linolenic acids (cLNA). They constitute a small percentage of fatty acids in the typical human diet, although up to 80% of the fatty acids in certain fruits such as pomegranate. In the course of studying a bacterial fatty acid dioxygenase (Nostoc linoleate 10S-DOX, an ancient relative of mammalian cyclooxygenases), we detected strong inhibitory activity in a commercial sample of linoleic acid.

Alfa-calendic acid and β-calendic acid, geometric and positional isomers of linolenic acid were previously shown to possess potent anticancer properties. In this study, we found that α-calendic acid and β-calendic acid could induce apoptosis and suppress invasion of human choriocarcinoma JEG-3 cells in vitro. Treatment with α-calendic acid and β-calendic acid significantly increased oxidative stress in human choriocarcinoma JEG-3 cells detected by the level of reactive oxygen species (ROS), lipid peroxidation production malondialdehyde (MDA), glutathione (GSH) and the effects of antioxidants NAC and α-tocopherol.

Background: Calendula officinalis L. (pot marigold) is an annual aromatic herb with yellow or golden-orange flowers, native to the Mediterranean climate areas. Their seeds contain significant amounts of oil (around 20%), of which about 60% is calendic acid.
