Antibacterial And Antifungal

The emergence and spread of resistant strains of pathogens as well as reduction of the efficacy of current antimicrobial agents requires the development of novel antimicrobial compounds. The aim of the present study was synthesis and evaluation of antimicrobial activity of new arylaliphatic aminopropanols. The objects of the present study were 1-[4-(1,1,3,3-tetramethylbutyl)phenoxy]-3-dialkylamino-2-propanol quaternary salts (compounds I–XIV). Compounds synthesis was carried out by heating of precursor epoxide and excessive amount of appropriate amines in isopropanole, followed by treatment with excess of alkyl halides. Methods of elemental analysis, IR- and PMR-spectroscopy were used for confirmation of chemical structure. Antimicrobial activity against Staphylococcus аureus АTCC 25923, Escherichia coli ATCC 25922, Pseudomonas aeruginosa АТСС 27853 and Candida albicans NCTC 885/653 was determined by a broth dilution method and evaluated via minimum inhibitory concentration (MIC). Our investigation of antibacterial and antifungal activity of 1-[4-(1,1,3,3-tetra methylbutyl)phenoxy]-3-dialkylamino-2-propanol quaternary salts showed that compounds possess narrow spectrum, as well as broad spectrum action. Significant antimicrobial activity of the novel aryl aliphatic aminoalcohols indicates their potential usage as a component of new antimicrobial drugs.

Tetrazole Derivatives

Abstract In recent years tetrazole scaffolds have been attracted interest in the field of synthetic and medicinal chemistry research. The unique structure of the tetrazole derivatives exhibits widespread applications in biology and technology. The close structural resemblance with carboxylic acid acts as a booster of the latter. Due to this diversified potential utilization, several methods are reported for the synthesis of tetrazole scaffolds. Here in this chapter, we describe the synthesis of chlorobenzyl-oxy-phenyl-ethyl-thio-1H-tetrazole derivatives ( 6a-p ). The newly synthesized derivatives are characterized by spectral characterization and screened for their antifungal activity. Among these, some of the newly synthesized compounds show potent antifungal activity.

Reaction of 2-(aminomethyl)benzimidazole dihydrochloride (1) with ethyl acetoacetate was studied to give diazepinone-benzimidazole derivative (2), while, treatment of 1 with phenylhydrazono ethylacetoacetate afforded phenylhydrazino diazepinone derivative (3). On the other hand, reaction of 1 with acetyl acetone resulted in the formation of diazepine derivative (4). The reaction of 1 with ethyl cyanoacetate was studied to give 3-aminodiazepinone derivative (5). Also the reaction of 1 with acetophenone and/or benzophenone has been investigated to give the fused imidazolines 6 and 7 respectively, while the reaction of 1 with cyclopentanone gave benzimidazolyl derivative (8). Treatment of 1 with chloroacetyl chloride gave the fused pyrazinone (9). The treatment of 1 with benzoin gave the derivative (10). The structures of the hitherto unknown compounds have been confirmed from analytical and spectral data. The newly synthesized compounds were screened for antibacterial and antifungal activity.
