A novel series of twenty 1,3-diphenylbenzo[f][1,7]benzonaphthyrdine derivatives were designed and synthesized through intermolecular imino Diels-Alder reaction. Their in vitro cytotoxic activities were evaluated against six human cancer cell lines (NCIH23, HCT15, NUGC-3, ACHN, PC-3, and MDA-MB-231). Majority of synthesized compounds exhibited significant cytotoxic activities against all tested human cancer cell lines. Among them 4l, 4m, and 4o derivatives exhibited most promising cytotoxic activities. Furthermore these compounds were evaluated against human Topoisomerase II alpha inhibition. Interestingly, the compound 4l exhibited 1.3 and 1.2 times more potent human Topoisomerase II alpha inhibition than the reference drug etoposide in both 100 mu M and 20 mu M concentrations respectively. Molecular docking studies for the compound 4l have also been executed by Sybyl X-2.1 in which it reveals the binding site of the compound 4l with topo II alpha DNA cleavage site where etoposide was situated. The benzo[f][1,7]naphthyridine ring was stacked between the DNA bases of the cleavage site. (C) 2017 Elsevier Ltd. All rights reserved.

In a document, author is Kong, Jichuan, introduce the new discover.

New lanthanide complex Gd-ANAMD containing 2-amino-7-methyl-1,8-naphthyridine was achieved for selective magnetic resonance imaging towards guanosine 5′-monophosphate over other ribonucleotide polyphosphates in aqueous media and in vivo. The formation of strong multi-hydrogen bonds between naphthyridine and guanosine made the phosphate in guanosine 5′-monophosphate positioned on a suitable site to coordinate with the lanthanide ion. The substitution of the coordination naphthyridine by the phosphate oxygen atoms caused obvious relaxivity decrease. The negligible cytotoxicity and appropriate blood circulation time of Gd-ANAMD allow potential application of Magnetic Resonance Imaging in vivo. H-1 NMR confirmed that the selectivity of these lanthanide complexes towards guanosine was attributed to the formation of hydrogen bonds between the guanine moeity and the naphthyridine. The fluorescence detection and lifetime measurement of Tb-ANAMD and Eu-ANAMD suggested that the decrease of the relaxivity is not attributed to the change of the q value, but caused by the prolonging of the residence lifetime of inner-sphere water.

In a document, author is Minakawa, Noriaki, introduce the new discover, Recommanded Product: Ethylene carbonate.

In this work, we investigated how thermally stable ImO(N):NaN degrees and ImN degrees:NaO(N) pairs are recognized by the Klenow fragment (KF). As a result, these complementary base pairs, especially the ImN degrees:NaO(N) pair, were recognized selectively due to the four hydrogen bonds between the nucleobases and the shape complementarity of the Im:Na pair similar to the purine:pyrimidine base pair.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.Welcome to check out more blogs about 96-49-1, in my other articles. Recommanded Product: Ethylene carbonate.

A series of dinuclear and tetranuclear first-row transition metal complexes were synthesized with the dinucleating ligand 2,7-bis(di(2-pyridyl) fluoromethyl)-1,8-naphthyridine (DPFN). The coordination pocket and rigidity of the DPFN ligand enforces pseudo-octahedral geometries about the metal centers that contain chloro, hydroxo, and aqua bridging ligands forming a diamond shaped configuration with metal-metal distances varying from 2.7826(5) to 3.2410(11) angstrom. Each metal center in the dinuclear complexes has an additional open coordination site that accommodates terminal ligands in a syn geometry of particular interest in catalyst design. The complexes are characterized by electronic spectroscopy, electrochemistry and potentiometric titration methods.

Dual-specificity tyrosine phosphorylation-related kinase 1A (DYRK1A) is a dual-specificity protein kinase that catalyses phosphorylation and autophosphorylation. Higher DYRK1A expression correlates with cancer, in particular glioblastoma present within the brain. We report here the synthesis and biological evaluation of new heterocyclic diphenolic derivatives designed as novel DYRK1A inhibitors. The generation of these heterocycles such as benzimidazole, imidazole, naphthyridine, pyrazole-pyridines, bipyridine, and triazolopyrazines was made based on the structural modification of the lead DANDY and tested for their ability to inhibit DYRK1A. None of these derivatives showed significant DYRK1A inhibition but provide valuable knowledge around the importance of the 7-azaindole moiety. These data will be of use for developing further structure-activity relationship studies to improve the selective inhibition of DYRK1A.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. If you like, you can also browse other articles about this kind. Thanks for taking the time to read the blog about 96-49-1, Product Details of 96-49-1.

In a patnet, author is Konovalov, Bata, once mentioned the new application about 96-49-1.

The synthesis, spectroscopic characterization, cytotoxic activity and DNA binding evaluation of seven new dinuclear platinum(ii) complexes Pt1-Pt7, with the general formula [{Pt(L)Cl}(2)(-1,5-nphe)](ClO4)(2) (1,5-nphe is 1,5-naphthyridine; while L is two ammines (Pt1) or one bidentate coordinated diamine: ethylenediamine (Pt2), (+/-)-1,2-propylenediamine (Pt3), trans-(+/-)-1,2-diaminocyclohexane (Pt4), 1,3-propylenediamine (Pt5), 2,2-dimethyl-1,3-propylenediamine (Pt6), and 1,3-pentanediamine (Pt7)), were reported. In vitro cytotoxic activity of these complexes was evaluated against three tumor cell lines, murine colon carcinoma (CT26), murine mammary carcinoma (4T1) and murine lung cancer (LLC1) and two normal cell lines, murine mesenchymal stem cells (MSC) and human fibroblast (MRC-5) cells. The results of the MTT assay indicate that all investigated complexes have almost no cytotoxic effects on 4T1 and very low cytotoxicity toward LLC1 cell lines. In contrast to the effects on LLC1 and 4T1 cells, complexes Pt1 and Pt2 had significant cytotoxic activity toward CT26 cells. Complex Pt1 had a much lower IC50 value for activity on CT26 cells compared with cisplatin. In comparison with cisplatin, all dinuclear Pt1-Pt7 complexes showed lower cytotoxicity toward normal MSC and MRC-5 cells. In order to measure the amount of platinum(ii) complexes taken up by the cells, we quantified the cellular platinum content using inductively coupled plasma mass spectrometry (ICP-QMS). Molecular docking studies performed to evaluate the potential binding mode of dinuclear platinum(ii) complexes Pt1-Pt7 and their aqua derivatives W1-W7, respectively, at the double stranded DNA showed that groove spanning and backbone tracking are the most stable binding modes.
