Screening target

The selection of compounds for an NMR screening library is dictated by its intended purpose. There are four basic types of libraries general screening, targeted, focused, and follow-up.

Chemical and biological screening complement each other very well The sensitivity of biological methods is much higher than that of chemical analyses and can detect even trace amounts, whereas the chemical screening targets new structures even if they are not obviously bio active. 

This chapter focuses on a novel antibiotic discovery paradigm. Metallo-hydrolases and Mur ligases are used to illustrate this approach. New methods to identify and prioritize targets, develop screens, and evaluate new inhibitors are discussed. New developments in enzyme-based assays, such as pathway assays, are also presented. This new approach is opening new venues for screening targets that are difficult to screen because substrates are not easily available.

A clear correlation has been observed between limiting surface tension ycmc and surfactant performance in water-in-C02 microemulsions, as measured by the phase transition pressure Ptnms- These results have important implications for the rational design of C02-philic surfactants. Studies of aqueous solutions are relatively easy to carry out, and surface tension measurements can be used to screen target compounds expected to exhibit enhanced activity in CO2. Therefore, potential surfactant candidates can be identified before making time-consuming phase stability measurements in high-pressure CO2. 

The sheer diversity of approaches to the design of a screening collection is enough to confuse a newcomer to the area. Which approaches actually work or, more pertinently, which will work for my needs This last question has been used by Roth to illustrate a universal truth diversity measures are irrelevant outside the context of application. State of the art approaches to the design of a screening collection use information about the intended use—for example a portfolio of intended screening targets—to provide this context.
