Drug development, molecule identification

Tlie previous chapter traced the evolution of a biologically ac-I ive compound isolated from plant material—cocaine—into an extensive series of drugs by chemical dissection of that molecule. A-iiother frequently applied approach to drug development depends on I ho identification and study of the organic compounds that regu-l. ite most of the functions of mammalian organisms the hormones,... 

The identification of suitable lead molecules is a crucial process with important implications for success in drug development. There is a growing common under-... 

Analytical methods are important not only in the development and manufacture of commercial biopharmaceutical drugs, they also play a vital role in the whole drug development life cycle. Drug discovery and preclinical research require development and application of analytical methodologies to support identification, quantitation, and characterization of lead molecules. It is difficult to perform a comparative potency assay on lead molecules if one does not know how much of each is going into the assay or how pure the molecule is. Analytical methods are typically developed, qualified, and validated in step with the clinical... 

NCEC is supposed to be the best analytical technique in proteomic, genomic, and drug development programs due to its inherent character of nano nature. Normally, amounts of samples in these disciplines are in nanoliters, which need this sort of device. Therefore, this modality of liquid chromatography has been used for the separation and identification of various molecules in different biological matrices. 

NMR spectroscopy has been applied at various stages of the drug development process.7 These applications can be broadly categorized as analytical NMR (identification and characterization of molecules of less than a few thousand daltons in mass) NMR-based screening (the measurement of NMR parameters, for a ligand, for mixtures of ligands, or for a macromolecular...
