In a document, author is Chaitanya, Muggu V. S. R. K., introduce the new discover.

Microwave-assisted synthesis of naphthyridinoylpyrazolidinones (7a-7j) has been achieved rapidly via the reaction of naphthyridine hydrazide (4) with different beta-keto esters and ethoxymethylenemalonic ester (EMME) (5a-5e). Initially, the reaction of naphthyridine hydrazide (4) with various beta-keto esters under microwave irradiation for 5 mins at 130 degrees C results in the formation of condensed products 6a-6j. This condensation was followed by cyclization, also, in diphenyl ether under microwave irradiation for 10 mins at 230-250 degrees C, yielding the corresponding cyclized products 7a-7j. Alternatively, both reactants 4 and each of the beta-keto esters/EMME (5a-5e) were treated in diphenyl ether under microwave irradiation for 15 mins at 230-250 degrees C giving the target molecules 7a-7j as one-pot reaction in good yields.

The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, their interactions with reaction intermediates and transition states. I hope my blog about 16415-12-6 is helpful to your research. Recommanded Product: 16415-12-6.

In a document, author is Madaan, Alka, introduce the new discover.

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.

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.
