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. COA of Formula: C6H14N2O.
Li, Zheng;Guo, Ming;Cao, Meng;Zhao, Tianming;Li, Mingzhu;Zhai, Xin research published 《 Discovery and antitumor activity of Benzo[d]imidazol-containing 2,4-diarylaminopyrimidine analogues as ALK inhibitors with mutation-combating effects》, the research content is summarized as follows. To address drug resistance caused by ALK kinase mutations, a series of novel 2,4-diarylaminopyrimidine (DAAP) analogs were designed by incorporating 1H-benzo[d]imidazol motif onto the maternal framework. All compounds were efficiently synthesized and antiproliferative activities against Karpas299, H2228 and A549 cell lines were evaluated by MTT assay. Delightly, the most promising derivative H-11 was detected with IC50 values of 0.016μM and 0.099μM against ALK- pos. Karpas299 and H2228 cells. Meanwhile, H-11 displayed encouraging enzymic inhibitory potency with IC50 values of 2.7 nM, 3.8 nM and 5.7 nM toward ALKWT, ALKL1196M and ALKG1202R, resp. Ultimately, the binding modes of optimal H-11 with ALK wild-type and mutants were ideally established which further confirmed the structural basis in accordance with the SARs anal.
103-76-4, 1-(2-Hydroxyethyl)piperazine is a useful research compound. Its molecular formula is C6H14N2O and its molecular weight is 130.19 g/mol. The purity is usually 95%.
1-(2-Hydroxyethyl)piperazine is a chemical solvent that is used for the absorption of amines and other compounds. It has been shown to have a high affinity for acidic substances, which may be due to its ability to form hydrogen bonds with them. 1-(2-Hydroxyethyl)piperazine is also used in sample preparation for the analysis of amines and other compounds in fruit extracts. The solubility of 1-(2-Hydroxyethyl)piperazine depends on the experimental conditions, including pH, temperature, and pressure. FT-IR spectroscopy has been used to measure the vibrational modes of 1-(2-Hydroxyethyl)piperazine molecules. The IR spectrum revealed that this compound contains a hydroxyl group and two fatty acid chains with one or more hydroxyl groups at their terminal end. The nmr spectrum showed that 1-(2-Hydroxyethyl)piperazine contains an NH proton as well as, COA of Formula: C6H14N2O
