Abstract:
A recent study revealed that Perillaldehyde (PAE), a natural compound from Perilla frutescens, characterized by claimed neuroprotective, antiallergic, antinflammatory, antimicrobial, antitumor, gastroprotective and antidiabetic activities, acts as a ligand of the EphA2 receptor, modulating its signaling through the inhibition of ephrin-A1-EphA2 binding. In this study, we investigated the interaction between PAE and EphA2 with binding and functional assays. Our data demonstrate that PAE neither interferes with ephrin-A1-EphA2 interaction, nor significantly affects ephrin-A1-induced EphA2 activation. PAE is just one of many instances that teaches how difficult and challenging it is to identify natural compounds characterized by selectivity and specificity towards a molecular target.

Structure of Conjugated Dienes
Conjugated dienes are compounds characterized by the presence of alternating double and single bonds. In a conjugated system like 1,3-butadiene, the unhybridized 2p orbital on each carbon overlaps continuously, allowing the π electrons to be delocalized across the entire molecule. In contrast, this type of overlap does not occur in cumulated and isolated dienes, such as 2,3-pentadiene and 1,4-pentadiene, respectively. Instead, the π electrons remain localized between the double...

Conformation
The simplest example of a diene is 1,3-butadiene, an acyclic conjugated π system. At room temperature, the molecule exists as a mixture of s-cis and s-trans conformers by virtue of rotation around the carbon–carbon single bond. Although the s-trans isomer is more stable, the...
Stability of Conjugated Dienes
A comparison of the enthalpies of hydrogenation of dienes reveals that conjugated dienes release less heat on hydrogenation, rendering them more stable than their nonconjugated analogs.
