Streptococcus pneumoniae: choosing rational protein targets for novel drug targets

Primary targets of fluoroquinolones in Streptococcus pneumoniae.

Mutants of wild-type Streptococcus pneumoniae IID553 with mutations in parC were obtained by selection with trovafloxacin, levofloxacin, norfloxacin, and ciprofloxacin. All of the parC mutants were cross-resistant to the selecting agents but were not resistant to gatifloxacin and sparfloxacin. On the other hand, gyrA mutants were isolated by selection with gatifloxacin and sparfloxacin. The gyr...

Choosing Targets for Gene Therapy

Novel targets for tuberculosis drug discovery.

Since the determination of the Mycobacterium tuberculosis genome sequence, various groups have used the genomic information to identify and validate targets as the basis for the development of new anti-tuberculosis agents. Validation might include many components: demonstration of the biochemical activity of the enzyme, determination of its crystal structure in complex with an inhibitor or a su...

Protein Drug Targets of Lavandula angustifolia on treatment of Rat Alzheimer᾽s Disease

Different treatment strategies of Alzheimer's disease (AD) are being studied for treating or slowing the progression of AD. Many pharmaceutically important regulation systems operate through proteins as drug targets. Here, we investigate the drug target proteins in beta-amyloid (Aβ) injected rat hippocampus treated with Lavandula angustifolia (LA) by proteomics techniques. The reported study sh...

Rational drug design and high-throughput techniques for RNA targets.

RNA molecules are the only known molecules which possess the double property of being depository of genetic information, like DNA, and of displaying catalytic activities, like protein enzymes. RNA molecules intervene in all steps of gene expression and in many other biological activities. Like proteins, RNAs achieve those biological functions by adopting intricate three-dimensional folds and ar...
