We report herein the design and synthesis of novel 7-(3-alkoxyimino-5- amino/methylaminopiperidin-1-yl)fluoroquinolone derivatives based on the structures of new fluoroquinolones IMB and DZH. The antibacterial activity of these newly synthesized compounds was also evaluated and compared with gemifloxacin, ciprofloxacin, and levofloxacin. Results revealed that all of the target compounds 10-27 have good potency in inhibiting the growth of Staphylococcus aureus including MSSA (MIC: 0.125-8 mug/mL), Staphylococcus epidermidis including MRSE (MIC: 0.25-16 mug/mL), Streptococcus pneumoniae (MIC: 0.125-4 mug/mL), and Escherichia coli (MIC: 0.25-0.5 mug/mL). In particular, some compounds showed useful activity against several fluoroquinolone-resistant strains, and the most active compound 15 was found to be 16-128, 2-32, and 4-8-fold more potent than the three reference drugs against fluoroquinolone-resistant MSSA, MRSA, and MRSE.

2-Pyridone is characterized by a very wide range of reactivity of a different nature, ranging from electrophilic aromatic substitution, CH-metal-mediated reactions, and NH/OH functionalization of both possible lactam/lactim tautomers, through cycloaddition, to nucleophilic addition and transformation of the tautomeric C=O/C-OH moiety. The high availability of 2-pyridones and the possibility of their far-reaching functionalization additionally increased their values. Therefore, they are very useful building blocks for the synthesis of structurally diverse piperidine and pyridine compounds, including naturally occurring 2-pyridones. This review reports on the use of simple 2-pyridones in the synthesis of alkaloids and alkaloids-inspired compounds based on the piperidine or pyridine framework. 1 Introduction 2 Structure, Availability, and Reactivity of 2-Pyridones 3 Monocyclic Piperidine Alkaloids from 2-Pyridones 4 Polycyclic Alkaloids, Their Derivatives, and Alkaloid-Inspired Compounds from 2-Pyridones 4.1 New Ring Formation Involving C/N Atoms of the 2-Pyridone Ring 4.1.1 Indolizine-Fused 2-Pyridones: Camptothecins and Related Compounds 4.1.2 Other Indolizines from 2-Pyridones 4.1.3 Compounds Bearing the Quinolizine Ring System 4.2 New Ring Formation Involving C/C Atoms of the 2-Pyridone Ring 4.2.1 C-2/C-3 Ring Fusion 4.2.2 C-3/C-4 Ring Fusion 4.2.3 C-4/C-5 Ring Fusion 4.2.4 C-5/C-6 Ring Fusion 4.2.5 C-2/C-4 Ring Bridge 4.2.6 C-2/C-6 Ring Bridge 4.2.7 C-3/C-5 Ring Bridge 4.2.8 C-3/C-6 Ring Bridge 4.2.9 C-4/C-6 Ring Bridge 5 Conclusion.

The rates of aminolyses of p-toluenesulfonyl chloride with primary and tertiary amines have been determined both in acetonitrile and in ethanol.The Broensted plots of log krel again pKa’ values fo amines (except hydrazine and 1,8-naphthyridine in acetonitrile) gave a good correlation when the aminolyses were carried out in acetonitrile.In ethanol, however, although Broensted plots with all tertiary amines show a good correlation, less basic hydrazine shows a higher reactivity than n-butylamine.The abnormal rate enhancement found with hydrazine is undoubtedly due to the alpha-effect, while with 1,8-naphthyridine in acetonitrile is considered to be due to the repulsion of two lone electron pairs on the two nitrogen atoms in 1,8-naphthyridine.

Owing to the growing need for novel antibacterial agents, we synthesized a novel series of fluoroquinolones including 7-substituted-1-(2,4-difluorophenyl)-6-fluoro-4-oxo-1,4-dihydro[1,8]naphthyridine-3-carboxylic acid derivatives, which were tested against clinically relevant Gram positive and Gram negative bacteria. Chemical structures of the synthesized compounds were identified using spectroscopic methods. In vitro antimicrobial effects of the compounds were determined via microdilution assay. Microbiological examination revealed that compounds 13 and 14 possess a good antibacterial profile. Compound 14 was the most active and showed an antibacterial profile comparable to that of the reference drugs trovafloxacin, moxifloxacin, and ciprofloxacin. A significant MIC90 value (1.95?mug/mL) against S. aureus ATCC 25923, E. coli ATCC 35218, and E. coli ATCC 25922 was recorded for compound 14. We observed reduced metabolic activity associated with compounds 13 and 14 in the relevant bacteria via a luminescence ATP assay. Results of this assay supported the antibacterial potency of compounds 13 and 14. An E. coli DNA gyrase inhibitory assay indicated that compound 14 is a potent inhibitor of E. coli DNA gyrase. Docking studies revealed that there is a strong interaction between compound 14 and the E. coli DNA gyrase enzyme. Genotoxicity and cytotoxicity evaluations of compounds 13 and 14 showed that compound 14 is non-genotoxic and less cytotoxic compared to the reference drugs (trovafloxacin, moxifloxacin, and ciprofloxacin), which increases its biological importance.

In an article£¬Which mentioned a new discovery about 1569-16-0

A Cu(i)-catalyzed retro-aldol reaction of beta-hydroxyketones with ortho-aminobenzaldehydes and nicotinaldehydes is reported that produces a range of quinolines and naphthyridines with high efficiency and selectivity. This reaction uses beta-hydroxyketones as a regiospecific ketone-protected enolate source via copper-catalyzed retro-aldol Calpha-Cbeta bond cleavage. The in situ generated copper enolate undergoes kinetically favorable cyclization with ortho-amino aryl aldehydes to produce quinolines and naphthyridines in a chemo- and regioselective manner. The mild and weakly basic reaction conditions also suppress possible side reactions of benzaldehydes under strongly basic conditions, resulting in improved reaction yields.
