Synthesis and biological evaluation of a series of fatty acid amides from Echinacea

Abstract Alkylamides are lipophilic constituents of Echinacea and possess numerous biological activities. Although significant effort has been focused on the study of crude Echinacea extracts, very little is known regarding the activities of the individual constituents that make up these herbal treatments. Herein we explore the SAR of simple alkylamides found in Echinacea extracts with respect to their ability to decrease the production of the pro-inflammatory mediator TNF-α. Our results have revealed the key structural requirements for activity and provide lead compounds for further investigation of these poorly understood molecules.

Chiral aggregates formed from methylated tetraenoic fatty acids: Formation of both antipodes of chiral aggregates from a single enantiomer and time-dependent stereomutation

(Chemical Equation Presented) Formation and behaviors of chiral aggregates of methylated tetraenoic fatty acids (TE-FAs) were reported. In the C-24 TE-FA series, the aggregate prepared by dispersing an ethanol stock solution of C-24 TE-FA 1b into sodium phosphate buffer gave a strong positive Cotton effect, whereas the aggregate prepared from a methanol stock solution gave a negative Cotton effect. In the C-20 TE-FA series, the aggregate prepared from an ethanol stock solution of C-20 TE-FA 2b exhibited time-dependent chirality inversion.
