A mild synthesis of substituted 1,8-naphthyridines

A greener method for the synthesis of substituted 1,8-naphthyridines has been developed, which is supported by reaction metric analysis. Using 2-aminonicotinaldehyde as a starting material with a variety of carbonyl reaction partners, the Friedlander reaction can be performed with high yield using water as the reaction solvent. Divergent reactivity was seen when using acrolein, and an alternative method was developed to give access to 2-vinyl-1,8-naphthyridine in high yield, and an assessment of addition reactions to 2-vinyl-1,8-naphthyridine was performed.

Catalytic activity in transfer hydrogenation using ruthenium (II) carbonyl complexes containing two 1,8-naphthyridine as N-monodentate ligands

A new series of novel complexes of type cis-[Ru(CO)(2)Cl-2(L)(2)], L = 2-phenyl-1,8-naphthyridine, 2-(4′-nitrophenyl)-1,8-naphthyridine, 2-(4′-bromophenyl)-1,8-naphthyridine, 2-(4′-methylphenyl)-1,8-naphthyridine, 2-(3′-methoxyphenyl)-1,8-naphthyridine, 2-(2′-methoxyphenyl)-1,8-naphthyridine and 2-(4′-methoxyphenyl)-1,8-naphthyridine have been successfully synthesized and characterized. We found that the complexes can be directly synthesized from [RuCl2(CO)(2)](2) with high yield. The crystallographic structures of complex cis-[RuCl2(CO)(2)(2-(4′-methoxyphenyl)-1,8-naphthyridine-kappa N8)(2)] and cis-[RuCl2(CO)(2)(2-(2′-methoxyphenyl)-1,8-naphthyridine-kappa N8)(2)] have been established by X-ray single crystal diffraction studies, which indicate an octahedral geometry with two 1,8-naphthyridine ligands coordinated to the metal in a N-monodentate fashion. The ruthenium(II) complexes have been studied as catalysts in the transfer hydrogenation of acetophenone. We found that complexes show moderate activities and a 100% selectivity. The best turnover frequency (390 h(-1)) is found for cis-[RuCl2(CO)(2)(2-(4′-methoxyphenyl)-1,8-naphthyridine-kappa N8)(2)] when the substrate/catalysis ratio was 1000/1. The catalytic conditions were optimized using different substrate/catalyst and base/catalyst ratios.

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).

A novel class of apical sodium-dependent bile salt transporter inhibitors: 1-(2,4-bifluoropheny1)-7-dialkylamino-1,8-naphthyridine-3-carboxamides

The apical sodium dependent bile acid transporter (ASBT) is the main transporter to promote re-absorption of bile acids from the intestinal tract into the enterohepatic circulation. Inhibition of ASBT could increase the excretion of bile acids, thus increasing bile acid synthesis and consequently cholesterol consumption. Therefore, ASBT is an attractive target for developing new cholesterol-lowering drugs. In this report, a series of 1-(2,4-bifluoropheny1)-7-dialkylamino-1,8-naphthyridine-3-carboxamides were designed as inhibitors of ASBT. Most of them demonstrated potency against ASBT transport of bile acids. In particular, compound 4a(1) was found to have the best activity, resulting in 80.1% inhibition of ASBT at 10 mu mol/L.

Chemistry of 2-cyanomethylene-4-thiazolidinone

This article is a brief review about the synthesis and chemistry of 2-cyanomethylene-4-thiazolidinone 1. The most significant applications of 4-thiazolidinone 1 in heterocyclic synthesis are due to its two reactive methylenes. The endo-cyclic methylene protons are activated by the neighboring carbonyl moiety and the exo-cyclic methylene protons by the adjacent cyano group. Different types of reactions, such as alkylation, coupling, and Knoevenagel condensation, as well as cyclization reactions are illustrated for the synthesis of different classes of biologically important heterocyclic skeletons from this novel precursor.

Synthesis and biological evaluation of 3-(1,3,4-oxadiazol-2-yl)-1,8-naphthyridin-4(1H)-ones as cisplatin sensitizers

A series of novel 3-(1,3,4-oxadiazol-2-yl)-1,8-naphthyridin-4(1H)-one derivatives were synthesized and their anti-cancer as well as cisplatin sensitization activities were evaluated. Among them, compounds 6e and 6h exhibited significant cisplatin sensitization activity against HCT116. Hoechst staining and annexin V-FITC/PI dual-labeling studies demonstrated that the combination of 6e/6h and cisplatin can induce tumour cell apoptosis. Western blot showed that the expression of ATR downstream protein, CHK1, decreased in 6e + cisplatin and 6h + cisplatin groups compared with that in the test compound and cisplatin group. Furthermore, docking of 6e/6h into the ATR structure active site revealed that the N1 and N8 atoms in the naphthyridine ring and the hybrid atom in the oxadiazole ring are involved in hydrogen bonding with Val170, Glu168 and Tyr155. Additionally, the naphthyridine ring is also involved in – stacking with Trp169. Accordingly, compounds 6e and 6h can be expected to be potential cisplatin sensitizers that can participate in HCT116 cancer therapy.

Regioselective Synthesis of Benzo[h][1,6]- naphthyridines and Chromenopyrazinones through Alkyne Cyclization

A regioselective approach to the synthesis of benzo[h][1,6]-naphthyridine and chromenopyrazinone derivatives was developed. The synthetic route to benzo[h][1,6]naphthyridines involves the N-propargylation of aromatic aminobenzaldehydes, followed by reaction with propargylamine in the presence of DBU (1,8-diazabicyclo[5.4.0] undec-7ene). For the synthesis of chromenopyrazine and chromeno-pyrazinone derivatives, the acetonitrile group was introduced to salicylaldehyde derivatives, and a DBU-promoted cyclization reaction between aldehydes and propargylamine gave the chromenopyrazines. The intramolecular heterocycloaddition reaction between the triple bond and the azadiene, which is formed as an intermediate, gave the desired structures.
