2-(3-(3,4-Dimethoxyphenyl)acrylamido)benzoic acid (cas: 53902-12-8) belongs to amides. Because of the greater electronegativity of oxygen, the carbonyl (C=O) is a stronger dipole than the N–C dipole. The presence of a C=O dipole and, to a lesser extent a N–C dipole, allows amides to act as H-bond acceptors. Amides can be recrystallised from large quantities of water, ethanol, ethanol/ether, aqueous ethanol, chloroform/toluene, chloroform or acetic acid. The likely impurities are the parent acids or the alkyl esters from which they have been made. The former can be removed by thorough washing with aqueous ammonia followed by recrystallisation, whereas elimination of the latter is by trituration or recrystallisation from an organic solvent.Electric Literature of C18H17NO5

Tranilast-delivery surgical sutures to ameliorate wound healing by reducing scar formation through regulation of TGF-β expression and fibroblast recruitment was written by Choi, Sung Yoon;Kim, Byung Hwi;Huh, Beom Kang;Jeong, Woong;Park, Min;Park, Hyo Jin;Park, Ji-Ho;Heo, Chan Yeong;Choy, Young Bin. And the article was included in Journal of Industrial and Engineering Chemistry (Amsterdam, Netherlands) in 2018.Electric Literature of C18H17NO5 This article mentions the following:

We describe surgical sutures enabled with the local, sustained delivery of a TGF-β inhibitory drug, tranilast. To fabricate drug-delivery sutures, we sep. prepared a tranilast-loaded strand using poly(lactic-co-glycolic acid), which was then phys. braided with a surgical suture already in clin. use. By this method, the drug-delivery sutures maintained the mech. strength and allowed the modulation of drug release profiles by simply altering the tranilast-loaded strand. The drug-delivery sutures herein released tranilast for up to 14 days. When applied to animal models, scarring was indeed reduced with diminished TGF-β expression and fibroblast numbers during the entire 21 day testing period. In the experiment, the researchers used many compounds, for example, 2-(3-(3,4-Dimethoxyphenyl)acrylamido)benzoic acid (cas: 53902-12-8Electric Literature of C18H17NO5).
