CGGRGD TFA is synthesized via solid-phase peptide synthesis technique and the surface of PCL fibers is aminolysised by amino 2-cyanobenzothiazole followed by the addition of 2-cyanobenzothiazole (CBT).

Sinapic acid protects the rat liver from CCl4-induced inflammation, most likely by acting as a free radical scavenger and modulator of NF-κB p65 activation and proinflammatory cytokine expression.
