Two birds with one stone: dendrimer surface engineering enables tunable periphery hydrophobicity and rapid endosomal escape was written by Wang, Zheng;Chen, Chao;Liu, Ruihong;Fan, Aiping;Kong, Deling;Zhao, Yanjun. And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2014.Quality Control of 1-Propylpiperazine This article mentions the following:

Multifunctional thermosensitive dendrimeric nanocarriers were generated via tailored surface modification. Such design not only facilitated the rapid endosomal escape of dendrimers, but also achieved tunable surface hydrophobicity, which could be employed to achieve on-demand cargo release. These smart dendrimers are promising for enhancing intracellular drug delivery. In the experiment, the researchers used many compounds, for example, 1-Propylpiperazine (cas: 21867-64-1Quality Control of 1-Propylpiperazine).

1-Propylpiperazine (cas: 21867-64-1) belongs to piperazine derivatives. The piperazine scaffold is often found in biologically active compounds in different therapeutic areas. These therapeutic areas include antifungals, antidepressants, antivirals, and serotonin receptor (5-HT) antagonists/agonists. Piperazine is an anthelminthic especially useful in the treatment of partial intestinal obstruction caused by Ascaris worms, which is a condition primarily seen in children. Piperazine hydrate and piperazine citrate are the main anthelminthic piperazines.Quality Control of 1-Propylpiperazine

Molecular Simplification of 1,4-Diazabicyclo[4.3.0]nonan-9-ones Gives Piperazine Derivatives That Maintain High Nootropic Activity was written by Manetti, Dina;Ghelardini, Carla;Bartolini, Alessandro;Dei, Silvia;Galeotti, Nicoletta;Gualtieri, Fulvio;Romanelli, Maria Novella;Teodori, Elisabetta. And the article was included in Journal of Medicinal Chemistry in 2000.SDS of cas: 21867-64-1 This article mentions the following:

Several 4-substituted 1-acylpiperazines, obtained by mol. simplification of 4-substituted 1,4-diazabicyclo[4.3.0]nonan-9-ones, have been synthesized and tested in vivo on the mouse passive avoidance test, to evaluate their nootropic activity. The results show that, apparently, an N-acylpiperazine group can mimic the 2-pyrrolidinone ring of 1,4-diazabicyclo[4.3.0]nonan-9-one, as the compounds of the new series maintain high nootropic activity. Moreover mol. simplification produces more clear-cut structure-activity relationships with respect to the parent series. The mechanism of action also appears to be similar in the two series. In fact, although the mol. mechanism remains to be elucidated, the most potent compound of each class is able to increase acetylcholine release in rat brain. Piperazine derivatives represent a new class of nootropic drugs with an in vivo pharmacol. profile very similar to that of piracetam, showing much higher potency with respect to the reference compound Among the compounds studied, 1-benzoyl-4-propionylpiperazine (DM235) shows outstanding potency, being active at a dose of 0.001 mg kg^-1 s.c.

Nitroaldol reactions catalyzed by amine-MCM-41 hybrids was written by Wang, Qingqing;Shantz, Daniel F.. And the article was included in Journal of Catalysis in 2010.Product Details of 21867-64-1 This article mentions the following:

The catalytic properties of several amine-functionalized MCM-41 materials in a nitroaldol (Henry) reaction are reported. The work investigated the effects of organoamine type (primary, secondary, tertiary), amine d., and the presence of silanol groups on the catalytic activity and product selectivity. High selectivity to the nitro alc. product was achieved by introducing secondary and tertiary amine groups on the MCM-41 surface, while the nitroalkene is the dominant product for primary amines. Steric effects appear to be significant in determining the overall reactivity as the least sterically hindered amines are the most active. The capping of silanols with trimethylsilyl groups resulted in a reduction in catalytic activity for nearly all samples, indicating the importance of surface silanols and/or the surface polarity in the reaction. In the experiment, the researchers used many compounds, for example, 1-Propylpiperazine (cas: 21867-64-1Product Details 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. 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.Product Details of 21867-64-1

A focused library of heterocyclic compounds including a 2-aminomethyl-1H-benzimidazole, 2-aminomethylindole, benzofuran-2-ylmethylamine, or 2-piperazin-1-ylmethylbenzoxazole fragment was screened for the ability to inhibit in vitro hepatitis C virus (HCV). The synthetic methods were described. The antiviral activity and cytotoxicity data were presented. Most of the compounds carrying a benzoxazol-2-ylmethylamine fragment inhibited Huh7.3 human hepatoma cells infected in vitro with HCV with nanomolar potency but were inactive against the HCV RNA-replicon. The only exception was 9-methyl-N(6)-(3-nitrophenyl)-2,3,4,9-tetrahydro-1H-carbazole-1,6-diamine, which demonstrated nanomolar potency against HCV in both models. The most active and selective compounds were (piperazin-1-yl)-[(1H-indol-2-ylmethyl)piperidin-4-yl]-ketones (EC₅₀ 0.31-2.2 渭M, CC₅₀ 10.2-110 渭M) and 2-(1,2,3a,4,5,6-hexahydropyrazino[3,2,1-jk]carbazol-3-yl)acetamide (EC₅₀ 1.69卤0.5 渭M, CC₅₀ 114卤42 渭M). The two most selective inhibitors I (TI₅₀ = 52) and II (TI₅₀ = 68) were selected for further preclin. trials. In the experiment, the researchers used many compounds, for example, 1-Propylpiperazine (cas: 21867-64-1SDS of cas: 21867-64-1).

1-Propylpiperazine (cas: 21867-64-1) belongs to piperazine derivatives. Industrial applications of piperazine include the manufacture of plastics, resins, pesticides and brake fluids.
