Product Details of 70006-24-5On October 27, 2006 ,《Gram Scale Synthesis of the Glucuronide Metabolite of ABT-724》 was published in Journal of Organic Chemistry. The article was written by Engstrom, Kenneth M.; Daanen, Jerome F.; Wagaw, Seble; Stewart, Andrew O.. The article contains the following contents:

A gram scale synthesis of the glucuronide metabolite of ABT-724 is reported. Glycosidic coupling between a trichloroacetimidate glucuronyl donor and a Cbz-protected hydroxypyridylpiperazine glycosyl acceptor is the key step in the synthesis, since attempts to directly glucuronidate the aglycon, aglycon derivatives, and other truncated glycosyl acceptors were unsuccessful. The route was used to produce 2.1 g of metabolite in eight steps from 2-chloro-5-hydroxypyridine in 21% overall yield. In the part of experimental materials, we found many familiar compounds, such as Abt-724(cas: 70006-24-5Product Details of 70006-24-5)

Abt-724(cas: 70006-24-5) belongs to piperazines. Piperazines are very broad chemical group, covering a wide range of drugs from antidepressants to antihistamines.Product Details of 70006-24-5

The article was 《Effects of antipsychotics and reference monoaminergic ligands on marble burying behavior in mice》. The article mentions the following:

Antipsychotics constitute efficacious augmenting agents in the treatment of anxiety disorders, including refractory obsessive-compulsive disorder. We examined the effects of 36 compounds, including typical, atypical and novel antipsychotics with dual dopamine D2/5-hydroxytryptamine 1A (D2/5-HT1A) actions on marble burying behavior in mice, a putative preclin. test for anxiety disorders. One hour after drug administration, male NMRI mice were placed individually in cages containing 20 marbles, and the total number of marbles buried after 30 min was counted. The selective serotonin reuptake inhibitors, citalopram (2.5-40 mg/kg), fluoxetine (2.5-10 mg/kg) and the benzodiazepine diazepam (2.5-10 mg/kg), reduced the number of buried marbles. The atypical antipsychotic, clozapine (0.16-10 mg/kg), but not its congener olanzapine, was effective in this test. Haloperidol, a typical antipsychotic, also reduced the number of buried marbles, albeit not in a dose-dependent manner. The atypical risperidone was partially active (0.16-0.63 mg/kg), as was the benzamide derivative, amisulpride, albeit at high (10-40 mg/kg) doses. Among the third-generation’ antipsychotics possessing combined D2/5-HT1A properties, bifeprunox was active at 0.0025 mg/kg, whereas SLV313 and aripiprazole were active only at the highest doses (2.5 and 10 mg/kg, resp.). SSR181507, F15063 and the antidyskinetic agent, sarizotan, were without any effect. Among a series of receptor subtype-selective ligands, only the 5-HT1A agonist, (+)-8-OH-DPAT (0.63-2.5 mg/kg) and the 5-HT2A/2B/2C antagonist, ritanserin (0.63-2.5 mg/kg) were active. Among novel antipsychotics with dual D2/5-HT1A properties, only bifeprunox was able to potently reduce the number of buried marbles. Inhibition of marble burying behavior may result from the interplay of several receptor systems, including 5-HT2 receptor blockade, dopamine D2 partial agonism and serotonin 5-HT1A agonism.

Grottelli, Silvia; Annunziato, Giannamaria; Pampalone, Gioena; Pieroni, Marco; Dindo, Mirco; Ferlenghi, Francesca; Costantino, Gabriele; Cellini, Barbara published an article in Journal of Medicinal Chemistry. The title of the article was 《Identification of Human Alanine-Glyoxylate Aminotransferase Ligands as Pharmacological Chaperones for Variants Associated with Primary Hyperoxaluria Type 1》.COA of Formula: C12H18N2O The author mentioned the following in the article:

Primary hyperoxaluria type I (PH1) is a rare kidney disease due to the deficit of alanine:glyoxylate aminotransferase (AGT), a pyridoxal-5′-phosphate-dependent enzyme responsible for liver glyoxylate detoxification, which in turn prevents oxalate formation and precipitation as kidney stones. Many PH1-associated missense mutations cause AGT misfolding. Therefore, the use of pharmacol. chaperones (PCs), small mols. that promote correct folding, represents a useful therapeutic option. To identify ligands acting as PCs for AGT, we first performed a small screening of com. available compounds We tested each mol. by a dual approach aimed at defining the inhibition potency on purified proteins and the chaperone activity in cells expressing a misfolded variant associated with PH1. We then performed a chem. optimization campaign and tested the resulting synthetic mols. using the same approach. Overall, the results allowed us to identify a promising hit compound for AGT and draw conclusions about the requirements for optimal PC activity. In the experimental materials used by the author, we found (3-(4-Methylpiperazin-1-yl)phenyl)methanol(cas: 123987-13-3COA of Formula: C12H18N2O)

Zhang, Xin; Lv, Xiao-Qin; Tang, Sheng; Mei, Lin; Li, Ying-Hong; Zhang, Jing-Pu; Jiang, Jian-Dong; Peng, Zong-Gen; Song, Dan-Qing published an article in European Journal of Medicinal Chemistry. The title of the article was 《Discovery and evolution of aloperine derivatives as a new family of HCV inhibitors with novel mechanism》.HPLC of Formula: 1688-95-5 The author mentioned the following in the article:

Aloperine (I), a Chinese natural product with a unique endocyclic scaffold, was first identified to be a potent hepatitis C virus (HCV) inhibitor in our laboratory Thirty-four new aloperine derivatives were designed, synthesized and evaluated for their anti-HCV activities taking I as the lead. Among them, compound II exhibited the potential potency with EC50 values in a micromolar range against both wild-type and direct-acting antiviral agents (DAAs)-resistant variants, and synergistically inhibited HCV replication with approved DAAs. Furthermore, it also owned a good oral pharmacokinetic and safety profile, suggesting a highly druglike nature. The primary mechanism showed that II might target host components, distinctly different from the DAAs currently used in clinic. Therefore, we consider aloperine derivatives to be a novel class of anti-HCV agents, and compound II has been selected as a promising antiviral candidate for further investigation. In the experimental materials used by the author, we found 4-Methyl-1-piperazinesulfonyl Chloride(cas: 1688-95-5HPLC of Formula: 1688-95-5)

And the article was published in European Journal of Medicinal Chemistry in 2019. Reference of 1-Methylpiperazine The author mentioned the following in the article:

Aiming to identify novel potent ALK and ROS1 dual inhibitors, the relatively bulky piperidine fragment in ceritinib was replaced with substituted imidazolidin-2-one moiety which gave rise to a series of 2,4-diaryl-aminopyrimidine (DAAP) analogs. SAR studies were conducted based on cellular assays on five cell lines and most compounds exerted moderated to excellent activities. Among them, 15(I) showed excellent inhibitory activities against ROS1 and ALK pos. cell lines, especially Ba/F3G1202R, with IC50 values ranging from 14 to 37 nM. As a continuation, several compounds were tested in enzymic assays and I displayed encouraging activities against wild-type ALK (1.2 nM), ROS1(0.43 nM) as well as extremely resistant ALKL1196M and ALKG1202R mutants with IC50 values of 0.73 nM and 6.7 nM, resp. To our delight, both cellular and enzymic results of I were in good accordance with western blot assays on H2228 and HCC78 cell lines. Importantly, pharmacokinetic (PK) profiles of I were obtained with quite satisfying AUC and Cmax values. Besides, the binding models of I with ALKWT, ALKG1202R and ROS1 clearly present the essential interactions within the active site. The experimental part of the paper was very detailed, including the reaction process of 1-Methylpiperazine(cas: 109-01-3Reference of 1-Methylpiperazine)

1-Methylpiperazine(cas: 109-01-3) can be used as mimic template in the preparation of molecularly imprinted microspheres (MIMs). It was also used to prepare the difunctional strong anion-exchange stationary phase from a 1,4-diazacyclohexane derivative..Reference of 1-Methylpiperazine

《Triphenylethylene analogues: Design, synthesis and evaluation of antitumor activity and topoisomerase inhibitors》 was published in European Journal of Medicinal Chemistry in 2020. These research results belong to Rani, Sudesh; Paul, Kamaldeep. SDS of cas: 109-01-3 The article mentions the following:

To structurally relate anticancer drug tamoxifen used in the treatment of breast cancer, a sequence of compounds I [R = piperidinyl, morpholino, 4-methylpiperazinyl, 4-ethylpiperazinyl, etc.] were designed and synthesized as potential drug candidates. McMurry coupling reaction was used as the key synthetic step in the preparation of these compounds I and the ratios of E/Z-isomers were determined on the basis of NMR and HPLC experiments The new compounds I were found to be cytotoxic in the micromolar range with 60 human tumor cell lines at one dose and five dose concentration levels. Detailed studies on the most active compounds I [R = 2-morpholinoethyl amine, cyclohexylamine and diethylamine] show these compounds were capable to inhibit the growth of cancer cells. Finally, with the aim to correlate the antiproliferative activity with an intracellular target(s), the effect on relaxation activity of DNA topoisomerase-II was assayed. The relevance of interaction of most active compounds with topoisomerase-II was demonstrated which was also supported by docking studies. The experimental process involved the reaction of 1-Methylpiperazine(cas: 109-01-3SDS of cas: 109-01-3)
