reported tyrosol sinapate (4) as a c-Met inhibitor hit. This study reports additional semisynthetic optimization and SAR of 4 to improve its selective activity against c-Met-dependent breast cancer by increasing its capacity to inhibit c-Met phosphorylation. Forty-three compounds (5-47) were synthesized, among which the novel analog homovanillyl sinapate (HVS-16) was distinguished for its remarkable activity

The invention relates to the use of para-coumaric acid or para-hydroxycinnamic acid derivatives in cosmetic or dermatological compositions, specifically to the use of at least one compound derived from para-coumaric acid having a general formula (I) below:
in which, especially, Z represents an oxygen or an —NH— group; X and Y are identical and each represent a CH or CH
2
group, as an active principle with depigmenting, free-radical-scavenging and/or antiinflammatory activity.
The invention also relates to the use of the above compounds for cosmetic care or for the preparation of a pharmaceutical composition, especially for depigmenting an area of skin, having antiradical and/or antiinflammatory activity.
Synthesis of Amide and Ester Derivatives of Cinnamic Acid and Its Analogs: Evaluation of Their Free Radical Scavenging and Monoamine Oxidase and Cholinesterase Inhibitory Activities
and selective MAO-B inhibitory activity. Compound 20 was the most potent inhibitor of MAO-B. Compounds 18 and 21 showed moderate BChE inhibitory activity. In addition, compound 18 showed potent antioxidant activity and MAO-B inhibitory activity. In a comparison of the cinnamic acid amides and esters, the amides exhibited more potent DPPH free radicalscavengingactivity, while the esters showed stronger
