OBJECTIVES To determine the antimicrobial susceptibility and serotype distribution of 205 isolates of Streptococcus pneumoniae, collected from the CSF of meningitis patients identified between 1998-2003, during sentinel meningitis surveillance in Egypt. METHODS Antimicrobial susceptibility was evaluated against six antibiotics using disc diffusion and(More)
BACKGROUND Pyrazole derivatives have been reported as both anticancer and antiinflammatory agents. OBJECTIVE This study was conducted to develop new pyrazole derivatives as potential anticancer and/or antiinflammatory agents. Their molecular mechanisms of action have been investigated. METHOD a series of new triarylpyrazole derivatives were synthesized.(More)
Synthesis of a new series of diarylamides possessing 6,7-dimethoxy(dihydroxy)quinoline scaffold is described. Their in vitro antiproliferative activities against NCI-58 human cancer cell lines of nine different cancer types were tested. Compounds 1a and 1d-g showed the highest mean %inhibition values over the 58 cell line panel at 10 μM, and they were(More)
Synthesis of a new series of 1,3,4-oxadiazole derivatives possessing sulfonamide moiety is described. Their in vitro antiproliferative activities against NCI-58 human cancer cell lines of nine different cancer types were tested. Compound 1k with p-methoxybenzenesulfonamido moiety showed the highest mean %inhibition value over the 58 cell line panel at 10 μM(More)
Antimicrobial peptides are a group of natural or semi-synthetic molecules possessing antimicrobial activities against bacteria, fungi, viruses, parasites, etc. They are considered as promising candidates for treatment of microbial infections and suppression of microbial resistance. The increasing emergence of bacterial resistance has required development of(More)
A series of diarylamides and diarylureas possessing 1,3,4-oxadiazole scaffold was designed and synthesized. Their in vitro antiproliferative activities were tested against a panel of 58 cell lines of nine different cancer types at the NCI, and compared with Sorafenib as a reference compound. Most of the compounds showed strong and broad-spectrum(More)
This article described the synthesis and in vitro antiproliferative activities a series of 6-(4-fluorophenyl)-5-(2-substituted pyrimidin-4-yl)imidazo[2,1-b]thiazole derivatives. The nine target compounds were tested for in vitro antitumor effect against a panel of 55 cell lines of nine different cancer types at the NCI, and their activities were compared(More)
A new series of diarylureas and diarylamides possessing 1H-pyrrolo[3,2-c]pyridine scaffold was designed and synthesized. Their in vitro antiproliferative activities against A375P human melanoma cell line and NCI-9 human melanoma cell line panel were tested. All the target compounds, except three amino derivatives 8g, h and 9h, demonstrated superior(More)
A novel series of substituted pyrimidine compounds bearing N-phenylpyrazole and terminating with aryl and cyclic sulfonamido moiety were designed, synthesized, and evaluated in vitro as antiproliferative agents against a panel of 53 cell lines of different tissues at the NCI. Among them, compound 1d with p-chlorobenzenesulfonamido terminal moiety, ethylene(More)
A novel series of 1,3,4-triarylpyrazole derivatives possessing terminal arylamide or arylurea terminal moieties has been designed and synthesized. Their in vitro antiproliferative activities were investigated against a panel of 58 cell lines of nine different cancer types at the NCI, USA. The urea analogues 2b, 2c, and 2f as well as the amide derivatives 3e(More)
