New analogues of antitubercular drug Delamanid were prepared, seeking drug candidates with enhanced aqueous solubility and high efficacy. The strategy involved replacement of phenoxy linker proximal to the 2-nitroimidazooxazole of Delamanid by piperidine fused 5 or 6-membered ring heterocycles (ring A). The new compounds were all more hydrophilic than Delamanid, and several class of analogues showed remarkable activities against M. bovis. And among these series, the tetrahydro-naphthyridine-linked nitroimidazoles displayed excellent antimycobacterial activity against both replicating (MABA) and nonreplicating (LORA) M. tb H37Rv and low cytotoxicity. Compared to Delamanid, these new compounds (6, 7, 45) demonstrated dramatically improved physicochemical properties and are suitable for further in vitro and in vivo evaluation.

DNA binding position and binding affinity of drugs are important information that helps medicinal chemists in synthesis of new drugs. We used molecular docking and molecular dynamics simulation to reveal binding strength of thieno[2,3-b]benzo[1,8]naphthyridine derivatives to DNA. Molecular docking showed that molecules with more steric hindrance select groove position in DNA structure. Other molecules are intercalated between base pairs of GC and AT. Restrained electrostatic potential (RESP) charges, root mean square deviation (RMSD), and total potential analyses were performed. RMSD and total potential analyses showed that all simulations have stability for MMGBSA analysis. Binding affinity of all drugs was derived via MMGBSA analysis. Thermodynamics analysis showed that binding affinity of groove binding drugs is less than that of intercalating ones. Also, it was found that a linear relationship exists between RESP charges and Delta G (pred). Additionally, our results demonstrated the highest affinity for molecules carrying substituent groups of-OCH3 and-CH3.

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 5959-52-4. Recommanded Product: 3-Amino-2-naphthoic acid.

A linear quantitative structure activity relationship (QSAR) model is presented for modeling and predicting the inhibition of HIV-1 integrase. The model was produced by using the stepwise multiple linear regression technique on a database that consists of 67 recently discovered 1,3,4-oxadiazole substituted naphthyridine derivatives. The developed QSAR model was evaluated for statistical significance and predictive power. The key conclusion of this study is that valence connectivity index order 1, lowest unoccupied molecular orbital and dielectric energy significantly affect the inhibition of HIV-1 integrase activity by 1,3,4-oxadiazole substituted naphthyridine derivatives. The selected physicochemical descriptors serve as a first guideline for the design of novel and potent antagonists of HIV-1 integrase. (C) 2010 Elsevier Masson SAS. All rights reserved.

A selective receptor for sensing and discriminating of GMP is useful not only in the energy metabolism but also in the processes of DNA replication and transcription-related to GMP; such a receptor is presently rare especially in a pure water environment. Herein, a novel 1,8-naphthyridine-based tripodal imidazolium gripper-like molecular served as a turn-on fluorescent receptor (TINP) was designed and synthesized for selective sensing and discriminating GMP from structurally similar GNPs (N = D and T) and XMPs (X = U, T, A, and C) in 100% aqueous solution. TINP consists of 1,8-naphthyridines and imidazolium cations. 2-acetylamino-1,8-naphthyridine was chosen as fluorophore and tri-hydrogen bonds interactions sites for the nucleobase guanine. Imida-zolium cations were identified as the phosphate part receiving moieties and communicators, while the three imidazolium cations also served as indispensable water-soluble parts. GMP caused a remarkable fluorescence enhancement (ca. 6.5-fold) with a quantum yield (Phi(f)) of 0.26 at 399 nm, displaying an efficient turn on behavior. The sensing mechanisms and fluorescence response were explained by Job’s plot, NMR spectroscopic analysis, and theoretical calculations. The turn-on fluorescent property for GMP can be attributed to photoinduced electron transfer (PeT) transitions with some mixed intraligand charge-transfer (ILCT) transitions. Finally, the preliminary results of cell experiments show that the receptor can be applied for the imaging of GMP in living mammalian cells.

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.

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.

A convenient synthis for 4-substituted and 3,4-disubstituted 1,7-naphthyridine-2(1H)-thiones 7 has been developed. The method is based on the electrocyclic reaction of 4-(1-arylalk-1-enyl)-3-isothiocyanatopyridines 6, generated in situ by the treatment of the respective isocyanides 5 with S8 in the presence of a catalytic amount of selenium. The isocyanides 5 can be easily prepared from commercially available pyridin-3-amine by conventional organic reactions.
