Novel pyrrolo[1(‘),5(‘)-a]-1,8-naphthyridine compounds (L1-L4) have been synthesized through a facile one-pot process by the reaction of the corresponding 1,8-naphthyridines with aliphatic anhydride. The structures were established by spectroscopic data.

Methyl 2-carbamate-1,8-naphthyridine thiophenolate derivative (NCTP) has been designed and synthesized, which can selectively bind to guanine derivatives. We immobilized NCTP on gold electrode and performed cyclic voltammetry analysis for guanosine sensing. The current blockage data obtained from these NCTP immobilized electrodes suggest that electrodes have higher selectivity for 2′-deoxyguanosine monophosphate (dGMP) than 2′-deoxythymidine monophosphate (dTMP), 2′-deoxycytidine monophosphate (dCMP), and 2′-deoxyadenosine monophophate (dAMP). Thus, synthetic reader molecule NCTP, which has complementary hydrogen bonding surface for guanine derivatives, could be useful for the sensing of guanosine mononucleotides and polynucleotides.

HIV-1 integrase catalyzes the insertion of viral DNA into the genome of the host cell. Integrase inhibitor N-(4-fluorobenzyl)-8-hydroxy-1,6-naphthyridine-7-carboxamide selectively inhibits the strand transfer process of integration. 4-Substituted pyrrolidinones possessing various groups on the pyrrolidinone nitrogen were introduced at the 5-position of the naphthyridine scaffold. These analogs exhibit excellent activity against viral replication in a cell-based assay. The preparation of these compounds was enabled by a three-step, two-pot reaction sequence from a common butenolide intermediate. (c) 2008 Elsevier Ltd. All rights reserved.

A series of neutral nonenzymatic receptors have been synthesized for the recognition of creatinine in a nondegrative way. The receptors contain different heterocyclic moieties for better interactions between host and guest. Among these,1,4, and5are fluorescent receptors for creatinine. From this study, it was found that the receptors1and4containing the naphthyridine moiety have higher binding affinity to the guest creatinine than receptors containing other heterocyclic moiety. Theoretical studies for the calculation of binding energy were carried out using discrete Fourier transform (DFT) for the hosts and their complexation with creatinine in both gas phase and acetonitrile medium.

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.

An unsymmetrical ligand, 2-(2-pyridinyl)-7-(pyrazol-1-yl)-1,8-naphthyridine (L-5) was prepared for the construction of a series of dinuclear complexes. Treatment of L-5 with [Ru-2(mu-OAc)(4)Cl] followed by anion metathesis afforded [(L-5)(mu-OAc)(3)Ru-2](PF6) (3). Reaction of L-5 with 2 equiv. of Ni(OAc)(2) provided [Ni-4(L-5)(2)(mu-OH)(4)(CF3COO)(2)](CF3COO)(2) (5). Reaction of [Re-2(CO)(8)(CH3CN)(2)] with L-5 in a refluxing chlorobenzene solution gave a mixture of dirhenium (6) and monorhenium (7) complexes. The monocobalt complex 8 was obtained from complexation of L-5 with CoCl2. These new complexes were characterized by elemental analysis and spectroscopic techniques. The structures of complexes 3, 5 and 8 were further confirmed by X-ray crystallography.
