Two unprecedented, homoleptic Pt-1,8-naphthyridine complexes have been prepared and characterized. Reaction between 1,8-naphthyridine (napy) and a platinum(II) precursor leads to a mononuclear homoleptic platinum(II) complex with stoichiometry [Pt(napy)(4)](OTf)(2). On the contrary, reaction between napy and a dinuclear platinum(III) precursor produces instead a rare example of a dinuclear, homoleptic, tetracationic platinum(II) complex with stoichiometry [Pt-2(napy)(4)](OTf)(4). Crystal structures of both complexes have been obtained. The redox behavior of the dinuclear complex has been studied by cyclic voltammetry, in order to establish its suitability as model precatalyst for organometallic reactions exploiting the Pt(II)/Pt(IV) or Pt(II)/Pt(III) manifold.

Benzimidazo[1,2-a]benzo[g]-1,8-naphthyridine (NB-1) and its donor-acceptor analog, 11-morpholino-benzimidazo[1,2-a]benzo(g)-1,8-naphthyridine-6-carbonitrile, (NB-2) have been synthesized and investigated for their optical and solvatochromic properties. Absorption and emission maxima of the push-pull chromophore, NB-2 were red shifted in comparison to NB-1 lacking in donor-acceptor motif. Both systems are highly fluorescent (phi = 0.74-0.84) and exhibit positive solvatochromism. Using solvatochromic shift method, we estimated 2 fold higher dipole moment in the excited state for NB-2 over NB-1. High degree of electronic charge redistribution in NB-2 seems to be responsible for its optical spectral red shifts and higher dipole moments compared to NB-1.

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 126-30-7 is helpful to your research. Category: naphthyridines.

Quantitative Structure Activity Relationship correlating the antitubercular and antibacterial (Staphylococcus aureus and Escherichia coli) activities with the structural descriptors of reported naphthyridine derivatives was developed. The data were divided into training and test sets. The former was used to develop the regression model and the latter was used to examine the predictive capability of these models. The statistical measures such as squared correlation coefficient (r (2) = 0.79-0.84), adjusted squared correlation coefficient (r (2) (adj) = 0.78-0.83) F-ratio (26.85-67.16), and cross-validation (q (2) = 0.74-0.79) were found to be satisfactory for all activities and the predictions were within the 99% confidence level. The models contained atom type, thermodynamic, structural, and electrotopological descriptors which emphasized the importance of the size, shape, and the lipophilicity of the molecule.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. In my other articles, you can also check out more blogs about 126-30-7. Name: 2,2-Dimethylpropane-1,3-diol.

The synthesis, characterization, spectroscopic properties of a new ligand 1,2-bis[2-(4-methyl-7-acetyl-amino-1,8-naphthyridine)]ethylene (L) and its two binuclear Cu(I) complexes containing triphenylphosphine (PPh3) or bis(diphenylphosphino)methane (dppm), [Cu-2(L)(PPh3)(4)](BF4)(2)center dot 2CH(2)Cl(2) (1 center dot 2CH(2)Cl(2)) and [Cu-2(L)(dppm)(2)](BF4)(2)center dot 4H(2)O (2 center dot 4H(2)O) are reported. The structural investigation of these compounds based on X-ray crystal analysis shows that the copper(I) centers adopt different coordination geometries, O(N)CuP2+ and NCuP2+ for complexes 1 and 2, respectively. Upon irradiation of a degassed organic solution of L at 365 nm, photoinduced isomerization reaction and an intramolecular proton transfer of ligand L were detailed studied by absorption spectral changes. A spectroscopic investigation involving time-dependent density functional theory calculations allows assignment of the excited states that relate to emission and transient absorption spectra. The observed lower-energy absorption bands appearing in the region of 413 and 418 nm for 1 and 2 in dichloromethane are assigned to ligand-to-ligand charge transfer (LLCT, phosphine -> napy) transition in nature. Compared with well-structured solid-state emission originating from pi pi* transition of ligand L, complexes 1 and 2 exhibit intense room-temperature solid-state emissions with lambda(max) at 586 and 620 nm, respectively. The energy and the shape of the emission bands are clearly different from that of the ligand, indicating the emissions come from different excited states. (C) 2011 Elsevier B.V. All rights reserved.

The complexes of 2,7-bis(diphenylphosphorylamino)-1,8-naphthyridine (L) with lanthanide nitrates Ln(NO3)(3) (Ln = Nd, Lu) were investigated to elucidate the coordination ability of a novel type of potentially tetradentate ligands – bis(phosphorylamino) substituted naphthyridines. Mononuclear complexes of 1:1 and 1:2 composition, namely, [Nd(L)(NO3)(3)] (1a), [Nd(L)(NO3)(3)]center dot H2O (1b), [Lu(L)(NO3)(2)(H2O)](NO3) (2), [Nd(L)(2)(NO3)(2)(H2O)](NO3) (3), [Lu(L)(2)(NO3)(H2O)](NO3)(2)center dot 0.75CH(3)CN center dot H2O (4a) and [Lu(L)(2)(NO3) (H2O)](NO3)(2) (4b) were synthesized and studied by IR, Raman, and P-31 NMR spectroscopy in solid state and in solution. Structures of the complexes 1b and 4a were determined by X-ray diffraction. According to X-ray crystallography, vibrational spectroscopy and C, H, N, P elemental analysis data in solid 1:1 complexes one neutral molecule of L serves most likely as O,O,N,N-tetradentate ligand while in the 1:2 complexes only one ligand molecule coordinates in the same O,O,N,N-tetradentate fashion, and the second one serves as O-monodentate one. In solution the coordination mode of the ligand is preserved in all complexes. (C) 2011 Elsevier B. V. All rights reserved.

New Advances in Chemical Research, April 2021.The transformation of simple hydrocarbons into more complex and valuable products via catalytic C¨CH bond functionalisation has revolutionised modern synthetic chemistry. 126-30-7, Name is 2,2-Dimethylpropane-1,3-diol, SMILES is OCC(C)(C)CO, belongs to naphthyridine compound. In a document, author is Yeh, Tzu-Chin, introduce the new discover, Recommanded Product: 2,2-Dimethylpropane-1,3-diol.

A series of bipolar host materials, namely, o-, m-, p-NPCz and o-, m-, p-NPDa, composing of electron-transporting naphthyridine (NP) and phenylene bridge with ortho-, meta-, and para-substituted hole-transporting carbazole (Cz)/diphenylamine (Da) were synthesized and characterized. By adjusting the linkage topology, the physical properties are subtly tuned. The characteristics of devices employing these new bipolar hosts with green thermally activated delayed fluorescence (TADF) emitter 1,2,3,5-tetrakis(carbazol-9-yl)-4,6-dicyanobenzene (4CzIPN) employed as emitter were investigated under the same device structure. Among these hosts, carbazole-based NPCz can perform efficient energy transfer from the host to the dopant and better exciton confinement in the emitting layer due to higher triplet energy and deeper HOMO/LUMO level than those of diphenylamine-based NPDa. The device with o-NPCz as bipolar host exhibits the best device performance with external quantum efficiency of 18.4% and low efficiency roll-off. However, o-, m-, p-NPDa with lower E-T and shallower HOMO levels than 4CzIPN exhibit inferior host to dopant energy transfer. Instead, the exciplex formation between host and 4CzIPN, which was verified by TRPL, led the resulting EL spectra of the NPDa-based devices broad with yellow to orange emissions.

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.

Novel Bacterial Topoisomerase Inhibitors Exploit Asp83 and the Intrinsic Flexibility of the DNA Gyrase Binding Site

DNA gyrases are enzymes that control the topology of DNA in bacteria cells. This is a vital function for bacteria. For this reason, DNA gyrases are targeted by widely used antibiotics such as quinolones. Recently, structural and biochemical investigations identified a new class of DNA gyrase inhibitors called NBTIs (i.e., novel bacterial topoisomerase inhibitors). NBTIs are particularly promising because they are active against multi-drug resistant bacteria, an alarming clinical issue. Structural data recently demonstrated that these NBTIs bind tightly to a newly identified pocket at the dimer interface of the DNA-protein complex. In the present study, we used molecular dynamics (MD) simulations and docking calculations to shed new light on the binding of NBTIs to this site. Interestingly, our MD simulations demonstrate the intrinsic flexibility of this binding site, which allows the pocket to adapt its conformation and form optimal interactions with the ligand. In particular, we examined two ligands, AM8085 and AM8191, which induced a repositioning of a key aspartate (Asp83B), whose side chain can rotate within the binding site. The conformational rearrangement of Asp83B allows the formation of a newly identified H-bond interaction with an NH on the bound NBTI, which seems important for the binding of NBTIs having such functionality. We validated these findings through docking calculations using an extended set of cognate oxabicyclooctane-linked NBTIs derivatives (similar to 150, in total), screened against multiple target conformations. The newly identified H-bond interaction significantly improves the docking enrichment. These insights could be helpful for future virtual screening campaigns against DNA gyrase.
