Disruption of the hypothalamic-pituitary-adrenal axis is an established finding in patients with anxiety and/or depression. Chronic corticosterone administration in animals has been proposed as a model for the study of these stress-related disorders and the antidepressant action. Alterations of the central noradrenergic system and specifically of inhibitory alpha(2)-adrenoceptors seem to be part of the pathophysiology of depression and contribute to the antidepressant activity. The present study evaluates in male rats the effect of chronic corticosterone treatment during 35 days (16-20 mg kg(-1) day(-1)) on the sensitivity of alpha(2)-adrenoceptors expressed in the somatodendritic and terminal noradrenergic areas locus coeruleus (LC) and prefrontal cortex (PFC), respectively. Further, the effect of chronic fluoxetine treatment (5 mg kg(-1), i.p., since the 15th day) on the sensitivity of alpha(2)-adrenoceptors was examined under control conditions and in corticosterone-treated rats. The alpha(2)-adrenoceptor functionality was analysed in vitro by agonist-mediated [S-35]GTP gamma S binding stimulation and in vivo through the modulation of noradrenaline (NA) release evaluated by dual-probe microdialysis. The concentration-effect curves of the [S-35]GTP gamma S binding stimulation by the agonist UK14304 (5-bromo-N-(4,5-dihydro-1H-imidazol-2-yl)-6-quinoxalinamine) demonstrated a desensitization of cortical alpha(2)-adrenoceptors induced by corticosterone (-logEC(50) = 6.7 +/- 0.2 vs 8.2 +/- 0.3 in controls) that was reverted by fluoxetine treatment (-logEC(50) = 7.5 +/- 0.3). Local administration of the alpha(2)-adrenoceptor antagonist RS79948 ((8aR,12aS,13aS)-5,8,8a,9,10,11,12,12a,13,13a-decahydro-3-methoxy-12-(ethylsulfonyI)-6H-isoquino [2,1 -g] [1,6]naphthyridine) (0.1-100 mu mol L-1) into the LC induced a concentration-dependent NA increase in the PFC of the control group (E-max = 191 +/- 30%) but non-significant effect was observed in corticosterone-treated rats (E-max = 133 +/- 46%), reflecting a desensitization of a 2 -adrenoceptors that control the firing of noradrenergic neurons. Fluoxetine treatment did not alter the corticosterone-induced desensitization in this area (E-max = 136 +/- 19%). No effect of fluoxetine on alpha(2)-adrenoceptor functionality was observed in control animals (E-max = 223 +/- 30%). In PFC, the local administration of RS79948 increased NA in controls (E-max = 226 +/- 27%) without effect in the corticosterone group (E-max = 115 +/- 26%), suggesting a corticosterone-induced desensitization of terminal alpha(2)-adrenoceptors. Fluoxetine administration prevented the desensitization induced by corticosterone in the PFC (E-max = 233 +/- 33%) whereas desensitized alpha(2)-adrenoceptors in control animals (E-max = -24 +/- 10%). These data indicate that chronic corticosterone increases noradrenergic activity by acting at different alpha(2)-adrenoceptor subpopulations. Treatment with the antidepressant fluoxetine seems to counteract these changes by acting mainly on presynaptic alpha(2)-adrenoceptors expressed in terminal areas.

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.

In a document, author is Sun, Qi, introduce the new discover, Product Details of 553-97-9.

A 2,7-naphthyridine derivative (AND-OH) was used as a fluorophore in the development of a novel fluorescent turn-on probe (AND-DNBS) by introducing a 2,4-dinitrobenzenesulfonate functionality. This fluorescent probe was successfully used for sensing glutathione (GSH) in aqueous media and showed favorable properties such as a rapid response time (45 s) and a significant Stokes shift (227 nm). The characteristics of the developed probe are better than those of another probe, namely ND-DNBS, which was also synthesized by our group and most other previously reported fluorescent probes for GSH. The AND-DNBS probe was able to detect GSH via a red emission in living A549 cells and zebrafishes. These results show that AND-DNBS has potential applications as an excellent probe for detecting GSH in various environments.

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 553-97-9. Product Details of 553-97-9.

In a patnet, author is Yao, Denghui, once mentioned the new application about 88847-89-6.

A novel and easily synthesized compound, N-(2-(2-benzothiazol-2-yl)vinyl-4-methyl-1,8-naphthyrine-7-yl)acetamide (1) based on naphthyridine and benzothiazole group, has been developed as a turn-on fluorescent chemosensor for Al3+ and Fe3+ simultaneously. The absorbance and fluorescent intensities of 1 increased linearly in aqueous solution upon the interaction of 1 with Al3+ or Fe3+. The other co-existing metal ions have no obvious effect on the detection. The Job’s plot and the ESI mass spectra indicated the formation of 1:1 complex between 1 and Al3+ or Fe3+. The sensing mechanism was proposed according to the Job’s plot, ESI mass spectra, H-1 NMR spectra, and density functional theory (DFT) calculation. The properties of the model compound N-(2-((2-methylbenzothiazol-6-ylimino)methyl)-4-methyl-1,8-naphthyridin-7-yflacetamide (2), which was designed and synthesized in order to prove the sensing mechanism, also verified the proposed sensing mechanism.

In an article, author is Mukherjee, Sanjukta, once mentioned the application of 5089-22-5, Name is 1,4-Bis(benzo[d]oxazol-2-yl)naphthalene. Now introduce a scientific discovery about this category, Category: naphthyridines.

Cyclophane-containing bis(2-amino-1,8-naphthyridine) moieties attached to variable linkers at the C2-position (linker B) were synthesized as cyclic mismatch-binding ligands (CMBLs). Ring-closing metathesis (RCM) is used as a key step for the introduction of double bonds at the linker B. Decreasing the size of the linker of the substrate, formation of the RCM products with an increasing trans/cis (E/Z) ratio was observed with moderate to high overall yields. Concentration-dependent fluorescence spectra were observed for CMBLs with longer linkers (n=3), whereas concentration-independent spectra were observed for CMBLs with shorter linkers (n=2 and/or 1) with a marked exception of the E-alkene 6a. Concomitant changes in the absorption as well as in the fluorescence spectra were also observed for the CMBLs with an increasing hydrophobicity of the solvent. Absorption and fluorescence spectra of the CMBLs in solutions containing 99-100% methanol resembled to that of the monomer. The binding behavior of these CMBLs with repeat DNA structures was investigated by using a surface plasmon resonance (SPR) assay and circular dichroism (CD) spectra. The cyclic E-alkenes 1a (n=3) and 3a (n=2) show an orthogonal binding relationship with d(CCTG)(9) and d(CAG)(9). However, the selectivity for the cyclic Z-alkenes increased with decreasing the length of the linker from compound 2b (n=3) to compound 7b (n=1). These compounds display a large molecular diversity, which allowed the tuning of the binding affinity and selectivity of the CMBLs by varying the linkers towards various biologically significant repeat DNA structures.

Bicycle ring closure on a mixture of (4aS, 8aR)- and (4aR, 8aS)ethyl 2-oxodecahydro-1,6-naphthyridine-6-carboxylate, followed by conversion of the separated cis and trans isomers to the corresponding thioamide derivatives, gave (4aSR, 8aRS)-ethyl 2-sulfanylidenedecahydro-1,6-naphthyridine-6-carboxylate, C11H18N2O2S. Structural analysis of this thioamide revealed a structure with two crystallographically independent conformers per asymmetric unit (Z’ = 2). The reciprocal bicycle ring closure on (3aRS, 7aRS)-ethyl 2-oxooctahydro-1H-pyrrolo[3,2-c]pyridine-5-carboxylate, C10H16N2O3, was also accomplished in good overall yield. Here the five-membered ring is disordered over two positions, so that both enantiomers are represented in the asymmetric unit.
