We have previously synthesized a series of 1,8-naphthyridine-3-carboxamide derivatives to identify potential anti-cancer/anti-inflammatory compounds. Three derivatives, 7-chloro-N-(3-(cyclopentylamino)-3-oxo-1-phenylpropyl)-6-fluoro-4-oxo-1-(prop-2-yn-1-yl)-1,4-dihydro-1,8-naphthyridine-3-carboxamide (C-22), 7-chloro-N-(2-hydroxy-3-oxo-1-phenyl-3-(phenylamino)propyl)-4-oxo-1-(prop-2-yn-1-yl)-1,4-dihydro-1,8-naphthyridine-3-carboxamide (C-31) and 7-chloro-6-fluoro-N-(2-hydroxy-3-oxo-1-phenyl-3-(phenylamino)propyl)-4-oxo-1-(prop-2-yn-1-yl)-1,4-dihydro-1,8-naphthyridine-3-carboxamide (C-34) demonstrated high cytotoxicity against a number of cancer cell lines and inhibited secretion of IL-1-beta and IL-6. In the present study, C-22, C-31 and C-34 were assessed for modulation of pro-inflammatory cytokines, TNF-alpha and IL-8, chemokine RANTES and NO produced by lipopolysaccharide (LPS)-treated mouse Dendritic cells (DCs). Among the 3 compounds, C-34 showed the most potent inhibition of inflammatory markers in DC model at 02 and 2 mu M. C-34 also significantly downregulated the secretion of TNF-alpha, IL-1-beta and IL-6 by murine splenocytes and THP-1 cells against IFS induced levels. In vitro effects of C-34 on bone marrow toxicity were assessed in CFU-GM assay. Human CPU-GM population was comparatively more sensitive to C-34 (0.1-10 mu M) than murine CPU-GM. IC50 values for murine and human CPU-GM were not attained. C-34 was further examined for in vivo suppression of LPS induced cytokines in a mice model. At doses ranging from 125 to 5 mg/kg, C-34 led to significant inhibition of TNF-alpha, IL-1-beta and MIP-1-alpha. At the highest dose of 5 mg/kg, C-34 also protected LPS-treated mice against endotoxin-induced lethality. In conclusion, C-34 demonstrates anti-inflammatory activity in vitro and in vivo in addition to cytotoxic properties. This finding suggests its potential for further development as a synthetic naphthyridine derivative with dual anti-cancer and anti-inflammatory (cytokine inhibition) properties.

Having gained chemical understanding at molecular level, chemistry graduates may choose to apply this knowledge in almost unlimited ways, as it can be used to analyze all matter and therefore our entire environment. 96-49-1, Name is Ethylene carbonate, SMILES is O=C1OCCO1, belongs to naphthyridine compound. In a document, author is Minakawa, Noriaki, introduce the new discover, Application In Synthesis of Ethylene carbonate.

In this work, we investigated how thermally stable ImO(N):NaN degrees and ImN degrees:NaO(N) pairs are recognized by the Klenow fragment (KF). As a result, these complementary base pairs, especially the ImN degrees:NaO(N) pair, were recognized selectively due to the four hydrogen bonds between the nucleobases and the shape complementarity of the Im:Na pair similar to the purine:pyrimidine base pair.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.Welcome to check out more blogs about 96-49-1, in my other articles. Application In Synthesis of Ethylene carbonate.

A new group of 5-(alkylamino)-9-isopropyl[1,2,4]triazolo[4,3-a][1,8]naphthyridine derivatives bearing a CONHR group at the 6-position (1c-g), designed to obtain new effective analgesic and/or anti-inflammatory agents, were synthesized and tested along with three new 9-alkyl-5-(4-alkyl-1-piperazinyl)-N,N-diethyl [1,2,4]triazolo[4,3-a][1,8]naphthyridine-6-carboxamides (2b-d). Besides, a new class of analogues of compounds 1 and 2, bearing a Mannich base moiety at the 9-position (12a-d), as well as the novel N,N-diethyl-5-(isobutylamino)-8-methyl-10-oxo-10H-pyrimido[1,2-a][1,8]naphthyridine-6-carboxamide (15) were prepared and tested. Compounds 1c-g exhibited very interesting anti-inflammatory properties in rats, whereas compounds 2b-d and 15 proved to be endowed with prevalent analgesic activity frequently associated with sedative effects in mice. On the contrary, the Mannich bases 12a-d resulted inactive. The most effective (80% inhibition of oedema) and potent (threshold dose 1.6 mg kg(-1) with 31% inhibition of oedema) anti-inflammatory compound 1d did not show gastrolesive effects following 100 mg kg(-1) oral administration in rats.

The continuous need for the development of new small molecule anti-cancer drugs calls for easily accessible sensor systems for measuring the effect of vast numbers of new drugs on their potential cellular targets. Here we demonstrate the use of an optical DNA biosensor to unravel the inhibitory mechanism of a member of a new family of small molecule human topoisomerase I inhibitors, the so-called indeno-1,5-naphthyridines. By analysing human topoisomerase I catalysis on the biosensor in the absence or presence of added drug complemented with a few traditional assays, we demonstrate that the investigated member of the indeno-1,5-naphthyridine family inhibited human topoisomerase I activity by blocking enzyme-DNA dissociation. To our knowledge, this represents the first characterized example of a small molecule drug that inhibits a post-ligation step of catalysis. The elucidation of a completely new and rather surprising drug mechanism-of-action using an optical real time sensor highlights the value of this assay system in the search for new topoisomerase I targeting small molecule drugs.

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.

The pursuit of miniaturization of magnetic electronic components spurs intensive theoretical and experimental researches on designing molecule-scale magnetic devices. Controlling the transport properties is one of the most vital focuses for magnetic molecular devices. In this work, magnetic devices constructed by a single epindolidione (Epi) molecule (5,11-dihydrodibenzo[b,g][1,5]naphthyridine-6,12-dione) bridging two zigzag graphene nanoribbon (zGNR) electrodes are theoretically designed. The Epi molecule can be converted between the keto and enol forms, which is confirmed by first principle molecular dynamics method. The influences of intramolecular proton transfer and the bridging manner between the core molecule and zGNR electrodes on the magnetic transport properties are investigated. Spin-resolved current-voltage (I-V) curves show that both the keto and enol devices display remarkable spin filtering effect. However, the effect of intramolecular proton transfer on the electron transport properties depends on the bridging manner between the Epi molecule and zGNR electrodes. When the Epi molecule is connected to zGNR electrodes with 4,7-sites (A bridging manner), the electron transport properties of molecular junctions are hardly affected by the intramolecular proton transfer. On the contrary, the conductance of the molecular junctions is significantly modulated by the intramolecular proton transfer when the Epi molecule is connected to zGNR electrodes with 4,4′-sites (B bridging manner). Further analysis reveals that the high spin filtering effect originates from stronger coupling between spin-up edge electronic states of zGNR electrodes and states of the core molecule. With B bridging manner, the conjugation characteristics of the Epi molecule as well as the transmission pathway of tunneling electrons can be largely modulated by the intramolecular proton transfer. Our work proposes a feasible way to control the conductance of single-molecule junctions by taking advantage of intramolecular proton transfer.

A dirhodium complex bearing a newly-designed silyl-1,8-naphthyridine ligand (napySi), [Rh(kappa Si-2,N-napySi)(H)(mu-Cl)](2) (1), was synthesized. Reaction of complex 1 with excess BH3 center dot SMe2 afforded a mononuclear borane adduct Rh[kappa Si-4,N,H,H-napySi(BH3)](H)Cl (2), revealing that rhodium and the uncoordinated naphthyridine nitrogen cooperatively captured BH3 and weakened its two B-H bonds. Complex 2 contains a Rh(mu-H)(2)B core composed of two Rh-H-B-3-center 2-electron (3c-2e) bonds where one Rh-H interaction is considerably weakened by strong trans-influence of the silyl ligand moiety.
