Anti-Infective Agents - Volume 10, Issue 2, 2012

The present article deals with the synthesis, antimicrobial and antimycobacterial activities of a novel series of N-(5-(2-(5-(arylidene)-4-oxo-3-phenylthiazolidin-2-ylidene)hydrazinecarbonyl)-4-methylthiazol-2-yl)benzamides (6a-o). The structures of these compounds have been elucidated by spectra (IR, 1H NMR, 13C NMR, mass spectra). All the synthesized compounds are screened for in vitro antibacterial activity against G Read More

Tuberculosis infections of the central nervous system are a serious and often fatal disease predominantly impacting young children. Having a success rate of approximately 10%, an in silico data mining search generated 23 analogs to isoniazid, which is a first-line tuberculostatic. All analogs retained the hydrazide functional group in addition to configurations including: quinoline, pyridine, indole, quinolin-4-ol, quinoline Read More

We investigated the in vitro and in vivo antimicrobial potential of a selective serotonin reuptake inhibitor sertraline hydrochloride, against clinical isolates of bacteria and Candida species. Minimum Inhibitory Concentration of sertraline against 161 human isolates of 12 Gram negative and 5 Gram positive genera, Candida albicans ATCC10231 and Candida tropicalis ATCC13803 was determined by spot inoculation, broth and a Read More

A new series of novel 1-(4-oxo-3-(3-methoxyphenyl)-3H-quinazolin-2-yl)-4-(substituted) thiosemicarbazides were synthesized by the reaction of 2-hydrazino-3-(3-methoxyphenyl) quinazolin-4(3H)-one with various methyl esters of dithiocarbamic acid. When tested for their in vitro antitubercular activity using H37Rv strain on Middle brook 7H11 agar slants with OADC growth supplement, all the test compounds inhibited the growth Read More

Leishmaniasis is a global disease, which has become a major health challenge for Pakistan and other developing countries. Infections caused by the parasitic protozoa constitute a major hindrance in socioeconomic development in many developing countries. In this study, we developed a topical application (gel), containing active ingredients derived from garlic, on which in vitro, in vivo, and clinical studies were conducted. Anti-lei Read More

In the present investigation, a series of 3-substituted-N-aryl-6,7-dimethoxy-3a,4-dihydro-3H-indeno[1,2- c]pyrazole-2-carboxamide analogs were synthesized based on the structure of known antitubercular drug thiacetazone and were evaluated for antitubercular activity by two fold serial dilution technique. A computational study was carried out for prediction of pharmacokinetic properties and none of the compounds viola Read More

As the human race is still threatened by prospective avian flu endemics, new motivations and systematic approaches should be placed high on agenda in order to alleviate the potential losses of both human life and local economics. A balance and comprehensive measures between economy and the ecosystem of the endemic regions must also be considered. One of the top priorities in these explorations should be e Read More

Enterobacteriaceae are major pediatric pathogens, but little is known regarding treatment options for multidrug-resistant strains. In this study, we investigated the susceptibility patterns of healthcare- and community-associated Enterobacteriaceae isolates expressing plasmid-borne, broad-spectrum beta-lactam resistance (PBLR). Using E-test methodology, we tested susceptibility to imipenem, meropenem, ertapenem, dori Read More

The mechanisms by which patients infected with T. cruzi develop or not the disease are not completely understood. We investigated the importance of parasite persistence as a factor in generating cardiomyopathy. Fifty trypomastigote forms from the Tulahuen strain were used as inoculum for 160 Albino Swiss mice. Parasitemia, survival, histopathological and electrocardiographic studies were done on days 90, 180, 270 and 36 Read More

A series of 4-thiazolidinone derivatives containing 1,4-benzodioxane ring system was synthesized starting from 2,3-dihydro-1,4-benzodioxane-2-carbohydrazide. The synthesized compounds were characterized and evaluated for antibacterial activity against Staphylococcus aureus, Escherichia coli and Bacillus subtilis and antifungal activity against Aspergillus niger, Aspergillus flavus and Candida albicans by two fold s Read More

Gram-positive cocci are responsible for many severe infections in community and hospital settings, and these multidrug resistant organisms have increased markedly in the past decade. This trend is particularly evident for methicillin/ oxacillin-resistant Staphylococcus aureus (MRSA). MRSA is any strain of Staphylococcus aureus that has developed resistance to beta-lactam antibiotics, which include the penicillins (methicillin, di Read More
