Metabolic syndrome is a widely prevalent multifactorial disorder associated with an increased risk of cardiovascular disease and type 2 diabetes mellitus. High plasma levels of insulin and glucose due to insulin resistance are a major component of the metabolic disorder. Thiazolidinediones (TZDs) are potent PPARγ ligands and used as insulin sensitizers in the treatment of type 2 diabetes mellitus. They are potent insulin-sensitizing agents but due to adverse effects like hepatotoxicity, a safer alternative of TZDs is highly demanded. The synthesis of N-(6-(4-(piperazin-1-yl)phenoxy)pyridin-3-yl)benzenesulfonamide derivatives I (R = 2,4-Cl2C6H3, 2,5-(OCH3)2C6H3, 2-thienyl, etc.) an alternate remedy for insulin resistance is reported. The experimental process involved the reaction of 1-(4-(4-Hydroxyphenyl)piperazin-1-yl)ethanone(cas: 67914-60-7).Recommanded Product: 67914-60-7

And the article contained the following:

Two zinc phthalocyanines, tetra-α-[4-(4-acetyl piperazine) phenoxy] phthalocyaninato zinc (C80H72N16O8Zn) and tetra-β-[4-(4-acetyl piperazine) phenoxy] phthalocyaninato zinc (C80H72N16O8Zn), have been synthesized and characterized with 1H NMR, MS, IR and elemental anal. The electronic absorption spectra of two complexes in common organic solvents (N,N-DMF, THF, n-octanol) were typical for nonaggregated phthalocyanines, showing a Q band at 693∼698 nm for 1 and 681 ∼ 682 nm for 2. This indicates that the Q band of zinc phthalocyanine with the substituted groups located in the α position is largely red shifted than that in the β position. The spectral features of complexes 1 and 2 in aqueous media suggest the α-substituted groups are more effective than β-substituted groups to hinder the aggregation of phthalocyanine mol. The interactions between two complexes with serum albumin and transferrin (BSA, HSA and apoTf) were investigated by absorption and fluorescence spectroscopy. The binding constants were found to be (1 ∼ 20) × 105 mol-1·L. By comparison, β-substituted 2 had stronger combining ability with albumin than that of α-substituted 1. The non-covalent conjugates (1-BSA, 2-BSA, 1-HSA, 1-apoTf and 1-FeTf) with the molar ratio of about 1 : 1 have also been prepared The photodynamic activities of two complexes and their bioconjugates against MCF-7 mammary tumor cells were examined The result shows that the photocytotoxicities of conjugates are higher than that of complexes 1 ∼ 2 and follows the order 1-BSA > 1-FeTf > 1-HSA, 1-apoTf > 2-BSA > 1>2.

A series of N-9 substituted 6-(4-(4-propoxyphenyl)piperazin-1-yl)-9H-purine derivatives (PP05-PP21) were prepared and evaluated for their anticancer activity against a panel of human cancer cell lines. Evaluation of results revealed that some of the synthesized compounds exhibited promising anticancer activity against the examined cancer cell lines. The structure-activity relationship (SAR) studies in the present work revealed that simple N-9 alkyl substituted 6-(4-(4-propoxyphenyl)piperazin-1-yl)-9H-purines are potent anticancer agents. Among all the compounds, PP17 (9-sec-butyl-6-(4-(4-propoxyphenyl)piperazin-1-yl)-9H-purine) showed good inhibitory activity against MCF-7 cells. Cell cycle anal. of the compound suggested that induces G2/M phase arrest. Biochem. experiments showed that PP17 significantly induced MCF-7 cell apoptosis. Therefore, compound PP17 with a potent in vitro anticancer activity can serve as a promising lead compound for further study.

On February 8, 2018, Hou, Jinqiang; Kovacs, Michael S.; Dhanvantari, Savita; Luyt, Leonard G. published an article.HPLC of Formula: 67914-60-7 The title of the article was Development of Candidates for Positron Emission Tomography (PET) Imaging of Ghrelin Receptor in Disease: Design, Synthesis, and Evaluation of Fluorine-Bearing Quinazolinone Derivatives. And the article contained the following:

Mol. imaging with positron emission tomog. (PET) is an attractive platform for noninvasive detection and assessment of disease. The development of a PET imaging agent targeting the ghrelin receptor (growth hormone secretagogue receptor type 1a or GHS-R1a) has the potential to lead to the detection and assessment of the higher than normal expression of GHS-R1a in diseases such as prostate, breast, and ovarian cancer. To enable the development of 18F radiopharmaceuticals, we have designed and synthesized three series of quinazolinone derivatives, resulting in the identification of two compound with subnanomolar binding affinity and one fluorine-bearing compound I with picomolar binding affinity (20 pM), representing the highest binding affinity for GHS-R1a reported to date. Two lead compounds (II, IC50 = 20.6 nM; III, IC50 = 9.3 nM) were successfully 18F-radiolabeled with radiochem. purity of greater than 99%. Mol. modeling studies were performed to shed light on ligand-receptor interactions. The experimental process involved the reaction of 1-(4-(4-Hydroxyphenyl)piperazin-1-yl)ethanone(cas: 67914-60-7).HPLC of Formula: 67914-60-7

And the article contained the following:

A novel series of 3-substituted-8-aryl-[1,2,4]triazolo[5,1-i]purin-5-amine analogs related to Sch 58261 was synthesized in order to identify potent adenosine A2A receptor antagonists with improved selectivity over the A1 receptor, physiochem. properties, and pharmacokinetic profiles as compared to those of Sch 58261. As a result of structural modifications, numerous analogs with excellent in vitro binding affinities and selectivities were identified. Moreover, compound I (R = MeOCH2CH2O) displayed both superior in vitro and highly promising in vivo profiles.
