Synthesis, Antimicrobial and Antitubercular Activities of Some Novel Carboxamide Derivatives of 2-quinolones
A series of novel substituted N-(3-acetyl-2-oxoquinolin-1(2H)-yl)benzamide (AJQC1AJQC12) have been synthesized upon refluxing 3-acetyl-1-amino-quinolin-2-one and substituted benzoic acid in the presence of dry redistilled pyridine and silicon tetrachloride as coupling agent. 3-acetyl-1-amino-quinolin-2-one (AJQ1-AJQ12) were synthesized from substituted 3-acetyl coumarin upon refluxing with hydr...
متن کاملBiological Activity of Some Magnesium(II) Complexes of Quinolones
A new magnesium complex of quinolone antibacterial agent was prepared. This new complex as well as a previously isolated complex of magnesium with ciprofloxacin were tested against various Gram positive and Gram negative microorganisms. Antimicrobial activities were evaluated using the agar diffusion test. The results have shown that all magnesium complexes are significantly less active than th...
متن کاملPhotodegradation of some quinolones used as antimicrobial therapeutics.
The photostability of the fluoroquinolones ciprofloxacin (CPX), ofloxacin (OFX), and fleroxacin (FLX) toward ultraviolet irradiation (UVA) and room light was investigated in dilute aqueous solutions. A series of photoproducts was observed by high-performance liquid chromatography (HPLC) for all three drugs. As little as 1 h of exposure to room light was enough for the formation of detectable am...
متن کاملPreparation of Some Meso-Disubstituted Anthracenes
The synthesis of some 9,10-disubstituted anthracene derivatives are described. 9,10-Bis(2-bromoethyl) anthracene 4,9,10-Bis (2-cyanoethyl) anthracene 5 and 9,10-Bis (4-hydroxybutyl) anthracene 11 are synthesized for the first time.
متن کاملsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
