چکیده

In this study, a new naphtol derivative was synthesized. The first stage, involved preparation of 1-[(2-Amino-ethylamino)-phenylmethyl]-naphthalen-2-ol (4) using a three-component system (β-naphtol [1], benzaldehyde [2], and ethylenediamine [3]), followed by the reaction of 4 with 3,5dinitrobenzoic acid (5) to form N-(2-{[(2-Hydroxy-naphtalen-1-yl)-phenyl-methyl]-amino}-ethyl)3,5-dinitro-benzamide (6) using a carbodiimide derivative or boric acid. The second stage, involves the synthesis of N-(2-aminoethyl)-3,5-dinitrobenzamide (7) by reaction of 5 with 3 using a carbodiimide derivative. Finally, the compound 6 was also synthetized using the three-component system (compound 7, benzaldehyde and â-naphtol). The structure of all compounds obtained was confirmed by elemental analysis, spectroscopy and spectrometry data. In conclusion, this method offers some advantages such as good yields, simple procedure, low cost, and ease of workup.

(E)-2-{[1-(3,11-Dimethyl-4-methyl­ene-10-oxo-1-phenyl-4,5,10,11-tetra­hydro-1H-benzo[b]pyrazolo­[3,4-f][1,5]diazo­cin-5-yl)ethyl­idene]amino}-N-methyl-N-(3-methyl-1-phenyl-1H-pyrazol-5-yl)benzamide

The central eight-membered ring of the title compound, C40H36N8O2, deviates from the ideal boat conformation because the bond between the exo-ethyl-ene group and the adjacent N atom is twisted by 60.0 (4)° due to steric hindrance. Its adjacent benzene and pyrazole rings are oriented almost perpendicular to each other, making a dihedral angle of 85.8 (3)°. In the crystal, the mol-ecules are link...

In Vitro Bactericidal Activity of 4- and 5-Chloro-2-hydroxy-N-[1-oxo-1-(phenylamino)alkan-2-yl]benzamides against MRSA

A series of nine substituted 2-hydroxy-N-[1-oxo-1-(phenylamino)alkan-2-yl]benzamides was assessed as prospective bactericidal agents against three clinical isolates of methicillin-resistant Staphylococcus aureus (MRSA) and S. aureus ATCC 29213 as the reference and quality control strain. The minimum bactericidal concentration was determined by subculturing aliquots from MIC determination onto s...

Duration of action of a broad range of selective κ-opioid receptor antagonists is positively correlated with c-Jun N-terminal kinase-1 activation.

The κ-opioid receptor is a widely expressed G-protein-coupled receptor that has been implicated in biological responses to pain, stress, anxiety, and depression, and its potential as a therapeutic target in these syndromes is becoming increasingly apparent. However, the prototypical selective κ-opioid antagonists have very long durations of action that have been attributed to c-Jun N-terminal k...

Synthesis and antimicrobial activity of some derivatives of (7-hydroxy-2-oxo-2H-chromen-4-yl)-acetic acid hydrazide.

(7-Hydroxy-2-oxo-2H-chromen-4-yl)-acetic acid hydrazide (2) was prepared from (7-hydroxy-2-oxo-2H-chromen-4-yl)-acetic acid ethyl ester (1) and 100% hydrazine hydrate. Compound 2, is the key intermediate for the synthesis of several series of new compounds such as Schiff's bases 3a-l, formic acid N'-[2-(7-hydroxy-2-oxo-2H- chromen-4-yl)acetyl] hydrazide (4), acetic acid N'-[2-(7-hydroxy-2-oxo-2...
