Synthesis and Antimicrobial Activity of Pyrazole Derivatives of 2-Cyclopropyl-1,8-naphthyridines

2-Amino-pyridine-3-carboxaldehyde and 3-cyclopropyl-3-oxopropionic acid ethyl ester react each other to provide 2-cyclopropyl-[1,8]-naphthyridin-3-carboxylic acid ethylester (1) which reacts with 99 % hydrazine hydrate to yield 2-cyclopropyl-[1,8]-naphthyridine-3-carboxylic acid hydrazide (2). This acid hydrazide (2), reacts with different acetophenones to yield respective Schiff bases (3a-h). Compounds 3a-h react with Vilsmeier-Haack reagent (DMF/POCl3) to furnish 1-(2-cyclopropyl-[1,8]-naphthyridine-3-carbonyl)-3-phenyl-1H-pyrazole-4-carbaldehydes (4a-h). 2-Cyclopropyl-[1,8]-naphthyridine-3-carboxylic acid hydrazide (2) on reaction with substituted acetylacetones and substituted ethyl acetoacetates gives substituted 2-cyclopropyl-[1,8]-napthyridin-3-yl)-(3,5-dimethyl-pyrazol-1-yl)-methanones (5a-d) and 2-(2-cyclopropyl-[1,8]-naphthyridine-3-carbonyl)-5-methyl-2,4-dihydropyrazol-3-ones (6a-c), respectively. On the other hand, hydrazide (2) reacts with different aromatic aldehydes yields 2-cyclopropyl-[1,8]-naphthyridine-3-carboxylic acid benzylidene-hydrazides (7a-g). Compounds (7a-g) on reaction with mercapto-acetic acid offered 3-[(2-cyclopropyl-[1,8]-naphthyridin-3-yl-methyl)aminolphenyl-thiazolidin-4-ones (8a-g). Interaction of acid hydrazide (2) with different aromatic acid chlorides afford N’-acetyl/benzoyl-2-cyclopropyl-1,8-naphthyridine-3-carbohydrazides (9a-d), which on treatment with POCl3 yield 2-cyclopropyl-[1,8]-haphthytidin-3-yl)-(5-phenyl-[1,3,4]-oxadiazol-2-yl)methanone (10a-d).

Synthesis and biological evaluation of new MET inhibitors with 1,6-naphthyridinone scaffold

A potent and novel MET inhibitor, 5-((4((2-amino-3-chloropyridin-4-yl)oxy)-3-fluorophenyl)amino)-3-(4-fluorophenyl)-1,6-naphthyridin-4(1H)-ones (8), was designed and synthesized via a scaffold-hopping strategy of a 2,7-naphthyridinone MET kinase inhibitor 7. Lead compound 8 had good potency (IC50 of 9.8 nM), but unfavorable pharmacokinetic profiles (F = 12%, CL = 5.0 L/h/kg). Systematic structural optimization of compound 8 resulted in 9g (MET, IC50 – of 9.8 nM) with a comparable MET potency to that of compound 2 and a favorable pharmacokinetic profile (F= 63%, CL = 0.12 L/h/kg). Further study of the derivatization of N(1) amine group of 9g led to the discovery of 23a with good MET potency (IC50 of 7.1 nM), promising VEGFR-2 selectivity (3226-fold), and a markedly drug-likeness improvement (F= 57.7%, CL = 0.02 L/h/kg). The excellent VEGFR-2 selectivity and favorable drug-likeness of 23g suggest that the 1,6-naphthyridine moiety could be used as a new scaffold for kinase inhibitor discovery.

Unsymmetrical triazolyl-naphthyridinyl-pyridine bridged highly active copper complexes supported on reduced graphene oxide and their application in water

A novel unsymmetrical triazolyl-naphthyridinyl-pyridine ligand was designed and synthesized, and employed in the synthesis of a heterogeneous copper complex on reduced graphene oxide. The resulting copper composite was characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and energy dispersive X-ray spectroscopy (EDX). This supported copper catalyst containing unsymmetrical triazolyl-naphthyridinyl-pyridine (only 0.1 mol%) showed excellent catalytic activity in water with good recyclability. Various functionalized quinoline derivatives were successfully synthesized in high yields through the green strategy in water. Other heterocyclic compounds, such as pyridine, 2-(pyridin-2-yl)quinoline, 1,8-naphthyridine, 5,6-dihydronaphtho[1,2-b][1,8]naphthyridine and 2-(pyridin-2-yl)-1,8-naphthyridine derivatives, were achieved in water with more than 80% yields. Mechanism studies revealed that this transformation occurs via dehydrogenation, condensation, and transfer hydrogenation and dehydrogenation processes which was supported by a deuterium labeling experiment.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 136-95-8. Application In Synthesis of Benzo[d]thiazol-2-amine.

Cyanido-Bridged Fe-II-M-I Dimetallic Hofmann-Like Spin-Crossover Coordination Polymers Based on 2,6-Naphthyridine

Two new 3D spin-crossover (SCO) Hofmann-type coordination polymers {Fe(2,6-naphthy)[Ag(CN)(2)][Ag-2(CN)(3)]} (1; 2,6-naphthy = 2,6-naphthyridine) and {Fe(2,6-naphthy)-[Au(CN)(2)](2)}center dot 0.5PhNO(2) (2) were synthesized and characterized. Both derivatives are made up of infinite stacks of {Fe[Ag(CN) (2)](2)-[Ag-2(CN)(3)]}(n) and {Fe[Au(CN)(2)](2)}(n) layered grids connected by pillars of 2,6-naphthy ligands coordinated to the axial positions of the FeII centers of alternate layers. The in situ generated [Ag-2(CN)(3)](-) linkers define wide rectangular windows that favor the interpenetration of three identical 3D networks, strong argentophilic interactions between them, and the generation of a densely packed structure without accessible void spaces. In contrast, the smaller rhombus-shaped window in 2 affords a structure made up of doubly interpenetrated 3D networks with strong aurophilic interactions between them and accessible voids partially occupied by nitrobenzene molecules. Compound 1 displays a relatively abrupt two-step SCO in the temperature interval 150-215 K, whereas 2 features an incomplete one-step SCO behavior (T-1/2 = 166 K) that extends over 150 K.
