Piperazines were originally named because of their chemical similarity with piperidine, part of the structure of piperine in the black pepper plant (Piper nigrum). 103-76-4, formula is C6H14N2O, Name is N-(2-Hydroxyethyl)piperazine. The -az- infix added to “piperazine” refers to the extra nitrogen atom, compared to piperidine. It is important to note, however, that piperazines are not derived from plants in the Piper genus.

Qi, Yueheng;Li, Ye;Fang, Yu;Gao, Hang;Qiang, Bingchao;Wang, Shuxia;Zhang, Huabei research published 《 Design, Synthesis, Biological Evaluation, and Molecular Docking of 2,4-Diaminopyrimidine Derivatives Targeting Focal Adhesion Kinase as Tumor Radiotracers》, the research content is summarized as follows. There are two important topics in the field of cancer research: one is targeted mol. therapy and the other is tumor mol. imaging. Focal adhesion kinase (FAK) is considered as an attractive target for oncol. diagnosis and therapy. A series of 2,4-diaminopyrimidine derivatives were labeled with 18F to study their biol. properties and their potential as positron emission tomog. tumor imaging agents. They inhibited the activity of FAK with IC50 values in the wide range of 0.6-2164 nM, among which the IC50 of Q6 was 3.2 nM. For the biodistribution in S180-bearing mice, the corresponding [18F]Q6 was relatively good, with the highest uptake of 3.35 ± 0.32 % ID/g at 30 min postinjection, with a tumor/muscle ratio of 2.08 and a tumor/bone ratio of 2.48. Accordingly, [18F]Q6 was considered as a potential PET imaging agent for tumor diagnosis.
