Over the past decades, pharmaceutical drug development has undergone some significant changes, a prominent example for this being the emergence of biomolecular drugs (New Biological Entities, NBEs) such as antibodies and peptides. However, classical small molecule drugs (New Chemical Entities, NCEs) are far from being a dying species, and in fact the number of NCE drugs approved by the US Food and Drug Administration (FDA) in the past few years has been higher with increasing trend compared to NBE drugs, which appear to stagnate at lower level in terms of new drug approvals…

Liquid handlers are ubiquitous and essential tools in every aspect of the drug discovery arena. Innovations in the past few decades resulted in a sizeable array of devices. With so many choices, it is important to identify appropriate instrumentation for a particular screening strategy, which should be based on unique capabilities and limitations. Intense advances in the design of liquid handling devices have broadened the capabilities to screen larger collections of compounds at a faster pace with increased reliability and efficiency. These innovations drift towards miniaturisation, in large part to reduce cost and increase throughput. A wide selection of fluid handlers has been developed for every aspect of drug discovery, which incorporate different technologies for discrete functions. Although this segment focuses on instrumentation relevant to the screening of small organic molecules, the perspectives presented herein can be valuable in the handling of oligonucleotides or biologics…
Autophagy is a cellular stress response to diverse stimuli such as starvation, infection and DNA damage. Autophagy plays important roles in the progression of various diseases including cancer, neurodegenerative diseases and Crohn’s disease. Despite recent advances in our understanding of the autophagy machinery, surprisingly little effort has been undertaken towards utilising this knowledge in drug discovery processes. Several phenotypic screens have been undertaken to identify drug candidates that modulate this process. Current highthroughput screening approaches assay the formation of the autophagosome and very little effort is made towards the identification of compounds that inhibit specific autophagy components. Here, I give an overview about potential molecular drug targets in the autophagy pathway and review the current status of targeted drug discovery towards identifying autophagy gene-specific drugs.
Although many of the marketed small molecule drugs have been discovered by research and development efforts within the pharmaceutical industry, there has been a paradigm shift with external sources increasingly being relied upon to fill their pipelines. This trend is likely to increase and the key pre-clinical activities carried out by organisations outside the pharmaceutical industry include target validation, assay development and their use in High Throughput Screening campaigns, validation of the Hit molecules, Hit-to-Lead and Lead-to-Candidate screening/chemistry. In order to perform these activities, adequate know-how and technical expertise is essential so that the processes meet appropriate industry standards. This article discusses some of the challenges associated with assay development and the automation of High Throughput Screening.
Deciphering crude proteomes in the quest for candidate biomarker signatures for disease diagnostics, prognostics and classifications has proven to be challenging using conventional proteomic technologies. In this context, affinity protein microarrays, and in particular recombinant antibody microarrays, have recently been established as a promising approach within high-throughput (disease) proteomics1-3. The technology will provide miniaturised set-ups capable of profiling numerous protein analytes in a sensitive, selective and multiplexed manner.
The majority of active pharmaceutical ingredients (APIs) are produced by crystallisation and so the phenomenon of polymorphism, whereby an organic molecule can adopt more than one crystalline form (Figure 1 opposite), is of considerable importance when trying to achieve consistent product quality during the manufacture of pharmaceutical solids and solid dosage forms. Although morphology and particle size-distribution are important solid-state characteristics, the uncontrolled occurrence of multiple physical forms (polymorphs, solvates, salts, co-crystals or amorphous) of an API can have significant effects on the performance of the material during processing, manufacture, storage and administration. For example, the solubility difference between some polymorphs has been shown to be over four times that of the least soluble form1 and can vary by significantly more for amorphous forms2.
