AbstractA combinatorial factory for the preparation and screening of polymeric coatings was developed. Coating formulations were prepared and coated using novel combinatorial techniques to obtain libraries of varying composition and thickness. The thickness of each film in a combinatorial array is rapidly determined via visible-light absorbance of optical dyes in conjunction with the Beer-Lambert relationship. These combinatorial libraries were then tested and screened using a variety of custom-made high-throughput methods. Combinatorial screening of oxygen and moisture vapor transmission rate, along with adhesive properties, are shown here. OTR and MVTR are determined using spectroscopic techniques. For adhesion, a spherical probe adhesive tester is able to generate parameters linked to tack, peel, and shear in one measurement. In addition to describing the testing methodology, benefits and shortcomings of these techniques will be highlighted.

Screening Technology

DNA-encoded combinatorial libraries (DECLs) represent an exciting new technology for high-throughput screening, significantly increasing its capacity and cost–effectiveness. Historically, DECLs have been the domain of specialized academic groups and industry; however, there has recently been a shift toward more drug discovery academic centers and institutes adopting this technology. Key to this development has been the simplification, characterization and standardization of various DECL subprotocols, such as library design, affinity screening and data analysis of hits. This review examines the feasibility of implementing DECL screening technology as a first-time user, particularly in academia, exploring the some important considerations for this, and outlines some applications of the technology that academia could contribute to the field.

Cherry Picking

The 1536-well microplate format has widely supplanted the 384-well microplate format for high-throughput screening and for IC50 assays. Previously, liquid chromatography/mass spectrometry (LC/MS) analyses of such samples required manual transfers of the wells of interest from a 1536-well plate into a 384-well plate. Because this manual transfer introduced a source of potential error, it became clear that amore appropriate solutionwould be to sample directly from the 1536-well plates. Currently, commercially available 1536-well plate autosamplers are not compatible with Waters LC/MS systems. The authors have modified their CTC PAL autosampler to support injection from up to twenty-four 1536-well plates. This allows them to cherry-pick any sample from up to 36,864 wells on the autosampler. Because of its success at this Institute, sampling from 1536-well plates has not only become the preferredmethod for LC/MS analysis from IC50 plates but also become the standard format used for the handling of and the sampling from large combinatorial libraries.

Great Ease

Recent advances in high-throughput, automated techniques combined with the identification of new therapeutic targets in genome sequencing and molecular biology have generated a need for a large collection of diverse heterocyclic scaffolds. This inspires toward the development of novel reaction sequences and linking strategies to generate libraries of diverse simple to complex heterocyclic systems. In this regard, combinatorial chemistry has emerged as an excellent technology platform for the rapid assembly of building blocks to synthesize complex molecular structures with great ease in a few synthetic steps. By means of the implementation of high-throughput screening for the biological evaluation of hits and leads, combinatorial libraries have become important assets in drug discovery and development. In the last two decades, the cyclorelease strategy that minimizes the chemical and tethering implications by releasing the intact desired target molecule in the final step of reaction has attracted much attention. Recently, a particular interest is developing in linking strategies, where loading and cleavage steps contribute to the complexity of the target structure rather than only extraneous manipulations. This review summarises the practical and high-yielding approaches of solid phase combinatorial synthesis for diverse high-purity heterocyclic skeletons of pharmacological importance involving the cycloelimination strategy.
