By Dev P. Arya

Advances that open new avenues in constructing aminoglycoside antibiotics over the past two decades, there were a number of advances within the figuring out of the chemistry, biochemistry, and popularity of aminoglycosides. This has resulted in the improvement of novel antibiotics and spread out new healing ambitions for intervention. this is often the 1st booklet to supply a whole review of contemporary advances within the box and discover their large strength for drug discovery and rational drug layout. With chapters written by way of a number of top specialists of their strong point components, the ebook addresses the chemistry, biology, and toxicology of aminoglycosides. Aminoglycoside Antibiotics: From Chemical Biology to Drug Discovery is a brilliant source for educational and business researchers in drug layout and mechanism reports and for researchers learning antibiotic resistance, antibiotic layout and synthesis, and the invention of novel prescription drugs. it's also a invaluable reference for graduate scholars in pharmacy, pharmaceutical technological know-how, biophysics, medicinal chemistry, and chemical biology.

Example text

The possibility that a hydrolase, KasE, could be a possible myo-inositolmonophosphate monophosphatase is provided by the expression of the respective gene in the kas-cluster. The myo-inositol is assumed to be directly incorporated into the first pseudodisaccharidic intermediate. We propose that the first step in NDP-kasugamine biosynthesis is 2-epimerization of the postulated UDP-N -acetyl-d-glucosamine precursor, which is suggested by the similarity of the KasQ protein with known UDP-(N -acetyl-)d-glucosamine 2-epimerases and catalyzes the conversion to UDP-N -acetyl-d-mannosamine.
