Page/Page column 49; 60, (2022/03/22)
The present disclosure relates to agonists of interferon alpha and beta receptor subunit 2 (IFNAR2) for use in the treatment or prevention of viral disease, particularly COVID-19. In particular embodiments, COVID-19 is associated with pneumonia or acute respiratory distress syndrome (ARDS). In other aspects, the subject being treated is undergoing extra-corporeal membrane oxygenation, mechanical ventilation, non-invasive ventilation, receiving oxygen therapy or receiving antiviral or steroid treatment.
Application of 1,8-naphthydinyl fluorescence molecular probe in research of ketamine entertainment abuse of neural mechanism and diagnosis of addiction degree
-
Paragraph 0057-0060, (2020/05/02)
The invention provides an application of 1,8-naphthyridinyl fluorescence molecular probes in the study of entertainment abuse neuromechanism of ketamine and the diagnosis of the addiction level.

Fluorescent probe for marking amyloid protein as well as preparation method and application thereof
-
Paragraph 0049-0052, (2020/01/12)
The invention belongs to the field of biomedicines, and concretely relates to amyloid protein-labeled fluorescence probes, and a making method and an application thereof. The fluorescence probes are compounds represented by formula I, and R1 and R2 in the formula I are independently selected from -CF3 and -CN. The invention also relates to the application of the compounds of formula I in amyloid protein labeling as the fluorescence probes. The compounds of formula I can be used for preparing products for diagnosing the Alzheimer's disease. BODIPY fluorescence probe molecules containing a bioactive 1,8-naphthyridyl group as a parent compound are synthesized for the first time, can be applied to beta-amyloid protein labeling, and can be used for the early stage diagnosis of the Alzheimer's disease.

RO8191 represents a newly discovered small-molecule IFN-like agent that displays potent anti-HCV activity. With it as lead, a series of compounds bearing an imidazo[1,2-α][1,8]naphthyridine core and an amide bond-linked side chain were designed and synthesized. These compounds were evaluated on HCV cell culture system (HCVcc-hRluc-JFH1), and some of them exhibited remarkable anti-HCV activity (EC50 = 0.017-0.159 μM) and low toxicity (CC50 > 25 μM). Moreover, it was revealed that these newly identified anti-HCV agents exert their antiviral effect through a distinct mechanism of action from that of RO8191 by targeting the viral entry process. Thus, our study provides a starting point for the development of potential HCV entry inhibitor.

Polymorphic equilibrium responsive thermal and mechanical stimuli in light-emitting crystals of N -methylaminonaphthyridine
Harada, Naomi,Abe, Yuichiro,Karasawa, Satoru,Koga, Noboru
supporting information, p. 6282 - 6285 (2013/02/25)
Crystal polymorphs of 1,8-naphthyridine derivative, being anti and syn conformers, show a reversible transformation from anti to syn by heating and from syn to anti by grinding with the alteration of emittance intensity, and notably, thermal transformation from anti to syn conformer took place in single-crystal-to-single-crystal (SC-to-SC) form, which was confirmed by a single crystal X-ray crystallography.
Synthesis and evaluation of fluorogenic 2-amino-1,8-naphthyridine derivatives for the detection of bacteria
Varadi, Linda,Gray, Mark,Groundwater, Paul W.,Hall, Andrew J.,James, Arthur L.,Orenga, Sylvain,Perry, John D.,Anderson, Rosaleen J.
experimental part, p. 2578 - 2589 (2012/04/23)
Several novel fluorogenic N-aminoacylnaphthyridine substrates were synthesized in good yield and tested for their ability to detect pathogenic bacteria in agar-based cell culture. Simple 2-N-(β-alanyl)amino-5,7- dialkylnaphthyridine substrates were selectively hydrolysed by β-alanylaminopeptidase expressing bacteria, but were subject to diffusion in the agar medium. Diffusion was reduced in the 2-N-(β-alanyl)amino-7- alkylnaphthyridine substrates with longer alkyl chains, but inhibition of growth was increased. 2-N-(β-Alanyl)amino-7-octylnaphthyridine inhibited the growth of all species tested, except for strains resistant to colistin/polymyxin, providing a rationale for the development of substrates for the selective detection of drug resistant species in clinical samples.

Large stokes shift induced by intramolcular charge transfer in N,O-chelated naphthyridine-BF2 complexes
Wu, Yun-Ying,Gou, Gao-Zhang,Mu, Wei-Hua,Du, Mei-Ling,Fu, Wen-Fu,Chen, Yong,Lv, Xiao-Jun
supporting information, p. 5226 - 5229,4 (2012/12/13)
Novel N,O-chelated naphthyridine-BF2 complexes with push-pull structures have been synthesized and characterized. Spectral investigations on these complexes reveal that photoinduced intramolecular charge transfer occurs and results in a large Stokes shift, which is further supported by density functional theory based theoretical calculations.

There is described 2-amino-5,7-disubstituted-naphthyridine and 5,7-disubstituted-naphthyridin-2(1H)-one derivatives with bronchodilating and hypotensive properties prepared by the reaction of 2,6-diaminopyridine with an appropriate β-diketone providing the 2-amino products. The 2-oxo analogs are prepared from the 2-amino products by treatment with nitrous acid.
