The novel piperazino-enaminone JOAB-40 reduced colitis severity in mice via inhibition tumor necrosis factor-α and interleukin-1β.

Biomed Pharmacother 2021 Sep 29;141:111852. Epub 2021 Jun 29.

Department of Pharmaceutical Sciences, University of Saint Joseph School of Pharmacy, Hartford, CT 06103, USA.

Brief Introduction: The synthetic compound enaminone E121 has an established role as a potent anti-tussive, bronchodilator and anti-inflammatory agent in asthma, cough, and colitis induced animal models. The addition of an N-alkylated piperazine motif to the terminal end of E121 lead to the generation of various analogues such as JOAB-40.
