SAR of the arylpiperazine moiety of obeline somatostatin sst₁ receptor antagonists was written by Hurth, Konstanze;Enz, Albert;Floersheim, Philipp;Gentsch, Conrad;Hoyer, Daniel;Langenegger, Daniel;Neumann, Peter;Pfaeffli, Paul;Sorg, Dieter;Swoboda, Robert;Vassout, Annick;Troxler, Thomas. And the article was included in Bioorganic & Medicinal Chemistry Letters in 2007.Synthetic Route of C10H12N4 This article mentions the following:

The SAR of over 50 derivatives of octahydrobenzo[g]quinoline (obeline)-type somatostatin sst₁ receptor antagonist 1 is presented, focusing on the modification of its arylpiperazine moiety. Sst₁ affinities in this series cover a range of five orders of magnitude with the best derivatives displaying subnanomolar sst₁ affinities and >10,000-fold selectivities over the sst₂ receptor subtype as well as promising pharmacokinetic properties. In the experiment, the researchers used many compounds, for example, 6-(Piperazin-1-yl)nicotinonitrile (cas: 149554-29-0Synthetic Route of C10H12N4).

6-(Piperazin-1-yl)nicotinonitrile (cas: 149554-29-0) belongs to piperazine derivatives. Piperazine causes primary dermal irritation and skin burns at high concentrations. Piperazine also causes eye irritation in humans. Although many piperazine derivatives occur naturally, piperazine itself can be synthesized by reacting alcoholic ammonia with 1,2-dichloroethane, by the action of sodium and ethylene glycol on ethylene diamine hydrochloride, or by reduction of pyrazine with sodium in ethanol.Synthetic Route of C10H12N4

Microarrays of over 2000 hydrogels – Identification of substrates for cellular trapping and thermally triggered release was written by Zhang, Rong;Liberski, Albert;Sanchez-Martin, Rosario;Bradley, Mark. And the article was included in Biomaterials in 2009.Application of 21867-64-1 This article mentions the following:

In this paper we describe an approach whereby over 2000 individual polymers were synthesized, in situ, on a microscope slide using inkjet printing. Subsequent biol. anal. of the entire library allowed the rapid identification of specific polymers with the desired properties. Herein we demonstrate how this array of new materials could be used for the identification of polymers that allow cellular adherence, proliferation and then mild thermal release, for multiple cell lines, including mouse embryonic stem (mES) cells. The optimal, identified hydrogels were successfully scaled-up and demonstrated excellent cell viability after thermal detachment for all cell lines tested. We believe that this approach offers an avenue to the discovery of a specific thermal release polymer for every cell line. In the experiment, the researchers used many compounds, for example, 1-Propylpiperazine (cas: 21867-64-1Application of 21867-64-1).

1-Propylpiperazine (cas: 21867-64-1) belongs to piperazine derivatives. Piperazine was first introduced as an anthelmintic in 1953. Piperazine compounds mediate their anthelmintic action by generally paralyzing parasites, allowing the host body to easily remove or expel the invading organism. Piperazines are very broad chemical group, covering a wide range of drugs from antidepressants to antihistamines. The connecting property of all these chemicals is the presence of a piperazine functional group.Application of 21867-64-1
