Novel N’-(2-hydroxy-3-methoxy-benzylidene)-1-ethyl-1,4-dihydro-7-methyl-4-oxo-1,8-naphthyridine-3-carbohydrazide [NBNCH] and its solid metal complexes with Cu-II, Ni-II and Co-II were synthesized and characterized by employing spectro-analytical techniques viz. elemental analyses, magnetic susceptibilities measurements, H-1 NMR, UV-Vis, IR, Mass, TGA, SEM-EDX, ESR and spectrophotometry studies. The HyperChem 7.5 software was used for quantum mechanical calculations. The geometry optimization, contour maps of highest occupied molecular orbitals (HOMO) and lowest unoccupied molecular orbitals (LUMO) and corresponding binding energy values of molecular and ionic forms of title compound were computed using semi empirical single point PM3 method, in order to understand the binding modes of metal complexes. The stoichiometric studies of complexes determined spectrophotometrically using Job’s continuous variation and mole ratio methods inferred 1:2 ratio in respective systems. The title compound and its metal complexes screened for antibacterial and antifungal properties indicated more pronounced activity of Cu-II complex compared to other compounds. The studies of nuclease activity for the cleavage of PBR322 DNA and MTT assay for in vitro cytotoxic properties showed high activity of Cu-II complex. The interaction studies of metal complexes with CT-DNA investigated by UV-Visible and fluorescence titrations revealed the intercalation mode of binding. Docking studies were also performed to illustrate the binding mode of the title compound with the target site of Thymidine phosphorylase from E. coli (PDB ID: 4EAF) protein.

Three boron fluorine complexes B1-B3 containing pyridine/1,8-naphthyridine were synthesized and structurally characterized. Compounds B1 and B2 exhibited strong fluorescence in solution and solid state. The solvent-dependent luminous properties and large Stokes shift in solution could be explained by intramolecular charge transfer, which is confirmed by time-dependent density functional theory calculation. The absolute quantum yield of B1 in powder form reached 0.48 because of inhibiting planar pi…pi stacking. Single-crystal X-ray diffraction analyses of B1 and B2 revealed that weak intermolecular C H…F and H…pi interactions hinder further stacking of pi…pi dimers, consequently preventing aggregation-induced quenching. Complex 113, composed of boron-dipyrromethene and 1,8-naphthyridine fluorophore, had potential applications as a pH ratiometric fluorescent sensor. (c) 2014 Elsevier Ltd. All rights reserved.

The synthesis and reactivity of a dinickel bridging carbene is described. The previously reported [i-PrND]Ni-2(C6H6) complex (NDI = naphthyridine-diimine) reacts with Ph2CN2 to generate a metastable diazoalkane adduct, which eliminates N-2 at 60 degrees C to yield a paramagnetic Ni-2(mu-CPh2) complex. The Ni-2(mu-CPh2) complex undergoes carbene transfer to t-BuNC via an initial isonitrile adduct, which upon heating releases free t-BuNCCPh2. On the basis of this sequence of stoichiometric reactions, a catalytic carbene transfer reaction is demonstrated.

Researchers are common within chemical engineering and are often tasked with creating and developing new chemical techniques, frequently combining other advanced and emerging scientific areas. 100-49-2, Name is Cyclohexanemethanol, SMILES is OCC1CCCCC1, belongs to naphthyridine compound. In a document, author is El-Naggar, Abeer M., introduce the new discover, HPLC of Formula: https://www.ambeed.com/products/100-49-2.html.

Background: One of the promising scaffolds in drug discovery is the fused pyrimidine derivatives. Objective and Method: Efficient synthesis of a novel series of 18 new 1,8-naphthyridine-3-carbonitrile, 2-amino pyrido[2,3-d] pyrimidine derivatives via multi-component reactions of aromatic aldehydes, active methylene, and an aromatic amine under microwave irradiation and evaluation of their anticancer activity and possible mechanisms. Results: Only compounds 5 (a-c)had a significant antiproliferative activity in hepatic HepG2 cells at submicromolar concentration (7.5-10 mu M). Similarly, only compound 11 (a-c) had a significant activity in breast MCF7 cells at (4-7 mu M). Derivatives with one methoxyphenyl substitution (5a and 11a) were not different from derivatives having dimethoxyphenyl substitution (5b and 11b). However, thiophene substitution (5c and 11c) enhanced the anticancer activity in both cells lines examined by 25% in HepG2 and by similar to 45% in MCF7 cells compared to a and b derivatives. All compounds were safe to both normal human lung cells (WI-38) and RBCs at concentrations up to 40 mM. The antiproliferative activity of compounds 5 (a-c) in HepG2 could be attributed to an induction of intrinsic apoptotic pathway as evidenced from the induction of initiator caspase 9 by similar to 4 folds. While, the activity of compounds 11 (a-c) could be attributed to their potential to inhibit tyrosine kinases (TK) by up to 85%. The IC50 of derivative 11c against TK was at 173 nM. Conclusion: The present study reported that derivatives 5 and 11 have merit for further investigation as anticancer and TK inhibitors.

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 100-49-2, in my other articles. HPLC of Formula: https://www.ambeed.com/products/100-49-2.html.

Studying quadruply hydrogen bonding (QHB) module interactions in materials matrices presents a significant challenge because a wide variety of non-covalent interactions may be relevant. Here we introduce a method of surface modification with DeUG (7-deazaguanine urea), DAN (2,7-diamido-1,8-naphthyridine) and UPy (2-ureido-4[1H]-pyrimidone) modules to form self-assembled monolayers (SAMs) on a glass surface. The QHB interactions under mechanical stress were investigated by measuring adhesion force using PS-DAN (DAN modified polystyrene), PBMA-DeUG (DeUG modified poly butyl methacrylate) and PBA-UPy (UPy modified poly butyl acrylate) as adhesion promoters. A mechanical lap-shear test was used to evaluate the fracture resistance of QHB heterocomplexes. The maximum load at fail showed that QHB interaction contributed significantly (72%) to overall adhesion. For the QHB modified glass surface, using a polymer modified with its complementary QHB partner greatly facilitated their pairing efficiency, up to 40% for DAN-DeUG. A general method from which single pair ruptures force of QHB modules could be obtained using thermodynamic data obtained from solution chemistry was proposed. Using this method, the single pair rupture force for UPy-UPy was measured as 160 pN, and the single pair rupture force for DAN-DeUG was obtained as 193 pN.

4-Ethyl-3-formyl-2,6-diphenylpyrylium perchlorate was obtained from 2,6-diphenylpyrylium perchlorate in three steps. Its reaction with triethyl orthoformate was accompanied by rearrangement of the initial pyrylium ring and led to pyrano[3,4-c] pyran-7-ium perchlorate system through a domino process involving ethanol addition-elimination. A plausible mechanism of the reaction is suggested on the basis of DFT quantum-chemical calculations. Reaction of the obtained pyrano[3,4-c] pyran-7-ium perchlorate with ammonium acetate led to a 2,7-naphthyridine derivative without a skeletal rearrangement.

A novelty rhodamine B based chemosensor containing 2-amino-7-methyl-1,8-naphthyridine moiety was designed and synthesized for colorimetric and fluorescent response on corresponding nucleoside polyphosphates through multi-hydrogen bond interaction in aqueous solution. The supramolecular recognition between the RBS and Cytidine-5′-diphosphate disodium hydrate (CDP) was investigated carefully: H-1 nuclear magnetic resonance confirmed that the formation of multi-hydrogen bonds between naphthyridine moiety and the nucleoside base group could untie the spiro structure of RBS, and the ESI-MS spectra proved the formation of the 1:1 complexation species between RBS and CDP. The strong emission response of the RBS toward COP and Adenosine-5′-triphosphate disodium trihydrate (ATP) ensures its application in living cells imaging. (C) 2013 Elsevier Ltd.

Cannabinoid type 2 (CB2) receptor has been implicated in several diseases and conditions, however no CB2 receptor selective drugs have made it to market. The aim of this study was to develop fluorescent ligands as CB2 receptor tools, to enable an increased understanding of CB2 receptor expression and signalling and thereby accelerate drug discovery. Fluorescent ligands have been successfully developed for other receptors, however none with adequate subtype selectivity or imaging properties have been reported for CB2 receptor. A series of 1,8-naphthyridin-2-(1H)-one-3-carboxamides with linkers and fluorophores appended in the N1 and C3-positions were developed. Molecular modelling indicated the C3 cis-cyclohexanol-linked compounds directed the linker out of the CB2 receptor between transmembrane helices 1 and 7. Herein we report fluorescent ligand 32 (hCB(2) pK(i) = 6.33 +/- 0.02) as one of the highest affinity, selective CB2 receptor fluorescent ligands reported. Despite 32 displaying poor specific labelling of CB2 receptor, the naphthyridine scaffold with this linker remains highly promising for future development of CB2 receptor tools.
