Molecular Recognition Studies on Naphthyridine Derivatives

The association constants Kb of three hosts I-III designed to have both enhanced hydrogen bonding donor strength and conformational preorganization with biotin analogues 1-5 are reported. H-1-NMR titrations under two different concentration conditions have been employed to determine the association constants Kb. A statistical analysis using a presence absence matrix has been applied to calculate the different contributions. Hydrogen bond interactions make naphthyridine derivatives II and III potent binders and effective receptors for (+)-biotin methyl ester (1), due to the complex stabilization by additional hydrogen bonds.

Facile synthesis of functionalized urea, imidazolium salt, azide, and triazole from a 2-amino-5,7-dimethyl-1,8-naphthyridine scaffold and their utilization in fluoride ion sensing

Four new 2-amino-5,7-dimethyl-1,8-naphthyridine derivatives (1-4) possessing urea, amide-imidazolium salt, amide-azide, or amide-triazole moieties were synthesized in good to excellent yields by derivatization of 2-amino-5,7-dimethyl-1,8-naphthyridine. We examined their anion recognition abilities towards different anions such as fluoride, chloride, bromide, iodide, nitrate, dihydrogen phosphate, cyanide, hexafluorophosphate, perchlorate, hydrogen sulphate and acetate by H-1 NMR and UV-Vis spectroscopy. Among various 2-amino-5,7-dimethyl-1,8-naphthyridine derivatives, only 1a and 2 showed spectroscopic and colorimetric change when treated with fluoride ions among other anions. The F- ions first established a hydrogen-bonding interaction with 1a to give the most stable 1:1 complex and then, after addition of a second equivalent, the F- ions induced urea deprotonation due to the formation of HF2-. Moreover, 2 underwent deprotonation of amide -NH proton after the addition of 1 equiv. of fluoride ions. The action of the probes was thoroughly investigated by DFT calculations that also supported the H-bonding induced deprotonation sensing mechanism.

1,8-Naphthyridines VI. Synthesis and anti-inflammatory activity of 5-(alkylamino)-N.N-diethyl[1,2,4]triazolo[4,3-a] [1,8]naphthyridine-6-carboxamides with a new substitution pattern on the triazole ring

On the basis of the good anti-inflammatory properties shown by the 9-alkyl-N,N-dialkyl-5-(alkylamino)[1,2,4]triazolo[4,3-a][1,8]naphthyridine-6-carboxamides 1, a series of analogues of such compounds, in which the 9-alkyl substituent was replaced by an ester or amide group (compounds 3a-i), was prepared and tested (inhibition of carrageenan-induced paw edema in the rat). Also two 5-(N-alkylN-acylamino) derivatives (compounds 4a,b) were synthesized and evaluated for the same purpose. Even though the general trend for these new [1,2,4]triazolo[4,3-a][1,8]naphthyridine derivatives was a decrease in activity compared with compounds 1, some of the new synthesized compounds exhibited still good anti-inflammatory properties.

Naphthyridine-BF2 complexes with an amide-containing di-2-picolylamine receptor: Synthesis, structures and photo-induced electron transfer

Two novel naphthyridine-BF2 compounds with an amide-containing di-2-picolylamine (DPA) receptor, namely 4 and 5, were synthesized and structurally characterized by various spectroscopic techniques and X-ray diffraction crystallography. The crystal structures of both mononuclear 4 and dinuclear 5 possessed a N,O-chelated naphthyridine-BF2 core, and the second BF2 unit in 5 was ligated to a basic amido N-atom together with a tertiary amine in the DPA part. The spectroscopic properties of 4 and 5 were investigated in various solvents and the difference between them was rationalized by the intramolecular charge transfer (ICT) and photo-induced electron transfer (PET) mechanism. Cyclic voltammetry measurements and theoretical calculations were carried out, and the results were in agreement with their spectral data. (C) 2013 Elsevier B.V. All rights reserved.

A new strategy for the synthesis of benzo[de][1,6]naphthyridine derivative 2,3,3a,4,5,6-hexahydroaaptamine, which involves the construction of the isoquinoline ring after elaboration of the quinoline moiety, is described. Since 2,3,3a,4,5,6-hexahydroaaptamine has been previously synthesized as a key intermediate en route to the marine alkaloid aaptamine, access to this compound represents a formal total synthesis of the natural product.

Synthesis and preliminary studies of C-11-labeled tetrahydro-1,7-naphthyridine-2-carboxamides for PET imaging of metabotropic glutamate receptor 2

Selective modulation of metabotropic glutamate receptor 2 (mGlu(2)) represents a novel therapeutic approach for treating brain disorders, including schizophrenia, depression, Parkinson’s disease (PD), Alzheimer’s disease (AD), drug abuse and addiction. Imaging mGlu(2) using positron emission tomography (PET) would allow for in vivo quantification under physiological and pathological conditions and facilitate drug discovery by enabling target engagement studies. In this paper, we aimed to develop a novel specific radioligand derived from negative allosteric modulators (NAMs) for PET imaging of mGlu(2). Methods. A focused small molecule library of mGlu(2) NAMs with tetrahydro naphthyridine scaffold was synthesized for pharmacology and physicochemical evaluation. GIRK dose-response assays and CNS panel binding selectivity assays were performed to study the affinity and selectivity of mGlu(2) NAMs, among which compounds 14a and 14b were selected as PET ligand candidates. Autoradiography in SD rat brain sections was used to confirm the in vitro binding specificity and selectivity of [C-11] 4a and [C-11]14b towards mGlu(2). In vivo binding specificity was then studied by PET imaging. Whole body biodistribution study and radiometabolite analysis were conducted to demonstrate the pharmacokinetic properties of [C-11] 14b as most promising PET mGlu(2) PET ligand. Results. mGlu(2) NAMs 14a-14g were synthesized in 14%-20% yields in five steps. NAMs 14a and 14b were selected to be the most promising ligands due to their high affinity in GIRK dose-response assays. [C-11] 14a and [C-11] 14b displayed similar heterogeneous distribution by autoradiography, consistent with mGlu2 expression in the brain. While PET imaging study showed good brain permeability for both tracers, compound [C-11] 4b demonstrated superior binding specificity compared to [C-11] 14a. Further radiometabolite analysis of [C-11] 4b showed excellent stability in the brain. Conclusions. Compound 14b exhibited high affinity and excellent subtype selectivity, which was then evaluated by in vitro autoradiography and in vivo PET imaging study after labeling with carbon-11. Ligand [C-11] 14b, which we named [C-11]MG2-1904, demonstrated high brain uptake and excellent in vitro/in vivo specific binding towards mGlu(2) with high metabolic stability in the brain. As proof-of-concept, our preliminary work demonstrated a successful example of visualizing mGlu2 in vivo derived from NAMs, which represents a promising chemotype for further development and optimization aimed for clinical translation.

Synthesis of Novel 1,7-Naphthyridines by Friedlander Condensation of Pyridine Substrates

The general ability of appropriate pyridyl compounds (aldehyde or ketone) to undergo Friedlander condensation to give different 1,7-naphthyridines has been demonstrated. 2,4-Disubstituted 1,7-naphthyridine 8 was prepared from 3-amino-4-acetylpyridine (6) and ketone 4 (82%). The Friedlander self-condensation of pyridyl substrate 6 is reported, as well. The dimer product, 2-(3-aminopyridin-4-yl)-4-methyl- 1,7-naphthyridine (7), was obtained in 97% yield. 2-Aryl-and 2,3-diaryl-1,7-naphthyridines (1618) were prepared from 3-aminoisonicotinaldehyde (13) and arylketones 4, 14, and 15 (28-71%). The key substrates 6 and 13 are readily available via the improved pyridine nitration method.
