6-(Piperazin-1-yl)nicotinonitrile (cas: 149554-29-0) belongs to piperazine derivatives. Simple N-substituted piperazines have been found in many drug molecules. Piperazine is formed as a co-product in the ammoniation of 1,2-dichloroethane or ethanolamine. These are the only routes to the chemical used commercially.COA of Formula: C10H12N4

[(S)-γ-(4-Aryl-1-piperazinyl)-L-prolyl]thiazolidines as a novel series of highly potent and long-lasting DPP-IV inhibitors was written by Yoshida, Tomohiro;Sakashita, Hiroshi;Akahoshi, Fumihiko;Hayashi, Yoshiharu. And the article was included in Bioorganic & Medicinal Chemistry Letters in 2007.COA of Formula: C10H12N4 This article mentions the following:

In the search for an inhibitor of dipeptidyl peptidase IV (DPP-IV) highly potent both in vitro and in vivo, a series of L-prolylthiazolidine-based DPP-IV inhibitors, e.g., I, having 4-arylpiperazine or 4-arylpiperidine at the γ-position of the proline structure was synthesized. Of these compounds, the 4-(5-nitro-2-pyridyl)piperazine analog I showed a sub-nanomolar (IC50 = 0.92 nmol/L) DPP-IV inhibitory activity and a long-lasting in vivo DPP-IV inhibition profile. In the experiment, the researchers used many compounds, for example, 6-(Piperazin-1-yl)nicotinonitrile (cas: 149554-29-0COA of Formula: C10H12N4).
