New research progress on 96-49-1 in 2021. 96-49-1, Name is Ethylene carbonate, molecular formula is C3H4O3, Recommanded Product: 96-49-1, SMILES is O=C1OCCO1 belongs to naphthyridine compound, is a common compound. 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.

New Advances in Chemical Research, April 2021. Formula: https://www.ambeed.com/products/6165-69-1.html, Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. 6165-69-1, Name is 3-Thiopheneboronic acid, SMILES is OB(C1=CSC=C1)O, belongs to naphthyridine compound. In a article, author is Oyama, Dai, introduce new discover of the category.

The asymmetric unit of the title compound, [RuCl2(C13H9N3)-(CO)(2)], consists of four crystallographically independent Ru-II complexes. Each RuII atom is in a distorted octahedral environment coordinated by two carbonyl ligands, two Cl atoms and a chelating 2-(2-pyridyl)-1,8-naphthyridine (pynp) ligand. The carbonyl ligands are cis to each other, while the Cl atoms are trans. Relatively short interatomic distances (2.60-2.67 angstrom) between the uncoordinated N atom of pynp and the C atom of the carbonyl imply a donor-acceptor interaction between the pynp and carbonyl ligands.

New Advances in Chemical Research in 2021. Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. 106-49-0, Name is p-Toluidine, molecular formula is , belongs to naphthyridine compound. In a document, author is Majumdar, Moumita, Category: naphthyridines.

A series of Mo-2, Ru-2, Rh-2 and Cu-2 complexes with redox-active NP-R [2-(2-R)-1,8-naphthyridine; R = pyrazinyl (NP-pz, L-1) and thiazolyl (NP-tz, L-2)] ligands have been synthesized and characterized by X-ray crystallography and spectroscopic methods. Two NP-R ligands wrap the dimetal core by occupying four equatorial positions and two axial sites. The remaining four equatorial sites are engaged by bridging acetates in quadruply bonded cis-[Mo-2(L-1)(2)(OAc)(2)][BF4](2) (1), cis-[Mo-2(L-2)(2)(OAc)(2)][BF4](2) (1A), doubly bonded cis-[Ru-2(L-1)(2)(OAc)(2)][ClO4](2) (3), cis- [Ru-2(L-2)(2)(OAc)(2)][ClO4](2) (3A) and singly bonded trans-[Rh-2(L-1)2(OAc)(2)][BF4](2) (5) and trans-[Rh-2(L-2)(2)(OAc)(2)][BF4] (2) (5A). Compounds cis-[Mo-2(L-1)(2)(CH3CN)(4)][BF4](4) (2), cis-[Mo-2(L-2)(2)(CH3CN)(4)][BF4](4) (2A), cis-[Ru-2(L-1)(2)(CO)(4)][OTf](2) (4) and cis-[Ru-2(L-2)(2)(CO)(4)][ClO4](2) (4A) contain acetonitriles or carbonyls as the ancillary ligands. The dicopper complexes trans-[Cu-2(CH3CN)(L-1)(2)][ClO4](2) (6) and trans-[Cu-2(L-2)(2)(ClO4)(2)] (6A) involve no bonding interaction between two Cu(I) units. Cyclic voltammogram studies reveal that two one-electron processes corresponding to each of the two ligands bound to the metal-metal bonded dimetal core result in four reversible one-electron reductions, with the exception of dirhodium(II,II) compounds 5 and 5A which show two one-electron reductions. The highest comproportionation constant (K-c) values are obtained for inter-valence complexes originating from the diruthenium(II,II) compounds 3 and 3A, whereas no electron delocalization is observed for dicopper(I,I) complexes 6 and 6A. The dimetal bridge and the ancillary ligands tune the degree of inter-ligand electronic coupling in these complexes. DFT calculations reveal a pi*(NP)-delta*(M-2)-pi*(NP) orbital conduit for electron delocalization. For diruthenium(II,II) compounds 3 and 3A, an additional pi*(NP) pi*(M-2) pi*(NP) pathway is accessible contributing to high K-c values. The ancillary pi-ligands (acetates and carbonyls) reduce the extent of the electron flow through pi*(NP)-delta*(M-2)-pi*(NP) and thus lower the K-c values. The absence of metal-metal bond orbitals and the reduced metal-ligand covalency in dicopper(I,I) compounds are responsible for the lack of electron delocalization in these systems.

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 106-49-0, Category: naphthyridines.

This type of reactivity has quickly become one of the cornerstones of modern catalysis .100-49-2, Name is Cyclohexanemethanol, SMILES is OCC1CCCCC1, belongs to naphthyridine compound. In a document, author is Fujimoto, Keisuke, introduce the new discover, SDS of cas: 100-49-2.

Pt-II-catalyzed cyclization of beta-to-beta ethynylene-bridged meso-amino Ni-II porphyrin dimer 4 followed by oxidation with PbO2 afforded 1,5-naphthyridine-fused porphyrin dimer 5 in good yield. This dimer possesses a redox-active 1,4-diazabutadiene linkage that is interconvertible with its reduced 1,2-diaminoethene linkage upon treatments with NaBH4 or PbO2. The dimer 5 exhibits an intense NIR absorption and a narrow HOMO-LUMO gap with a remarkably low reduction potential mainly due to effective bonding interactions in the LUMO through the 1,4-diazabutadiene linkage. In contrast, the reduced dimer 7 is fairly electron-rich with high HOMO energy and shows a relatively large HOMO-LUMO gap compared to that of 5.

The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules. I hope my blog about 100-49-2 is helpful to your research. SDS of cas: 100-49-2.
