A Caffeic acid phenethyl amide (CAPA) is the amide derivative of caffeic acid phenethyl ester (CAPE), a bioactive extract from propolis. CAPE has been extensively studied and shown to be cytotoxic in many cancer cell lines. CAPE is also an inhibitor of angiogenesis and may decrease resistance to traditional chemotherapeutics. Although CAPE has been well characterized very little is known about the biological activity of CAPA. We synthesized a library of CAPA analogues to be used to treat various cancer cell lines to determine if the extensive cytotoxicity observed in CAPE is preserved. Previous studies have established that CAPE is a potent inhibitor of p38α through interactions with the D-recruitment site (DRS). We employed computational docking via AutoDock Vina to gain insight into the potential differentiation in modes of binding between CAPE and CAPA. This in silico work has revealed that CAPE preferentially binds to a previously unidentified hydrophobic pocket in the DRS whereas CAPE does not.
