Practical considerations in analysing biologically active peptides by Electrospray Ionisation (ESI) Mass Spectrometry

22 October 2013 | By Birthe V. Nielsen, Faculty of Engineering and Science, University of Greenwich

Neuromodulators such as calcitonin gene-related peptide (CGRP) and vasoactive intestinal peptide (VIP) act as biomarkers for pain assessment (pre-clinical). These markers can be detected at low concentrations by Electrospray Ionisation (ESI) Mass Spectrometry (MS). Currently, little is known about the factors affecting responsiveness in the ESI process though the response…

Cell-based assays for protein-protein interactions

22 October 2013 | By Mark Wade, Center for Genomic Science of IIT@SEMM

Protein-protein interactions (PPI) form the backbone of all cellular signalling networks, and aberrant PPI contribute to the pathology of several diseases. Thus, strategies to identify PPI modulators are expected to be therapeutically beneficial. However, there are very few examples of clinically approved PPI modulators, reflecting the difficulties of identifying effective…

Raman spectroscopy: an enabling tool for accelerating pharmaceutical discovery to development

20 August 2013 | By Chanda R. Yonzon, Atul Karande, Sai P. Chamarthy and Brent A. Donovan (Merck & Co. Inc)

Raman spectroscopy has emerged as the preeminent analytical tool for a number of applications within drug discovery and development. Advances in the instrumentation, sensor fabrication and data analysis have enabled the wider acceptance of Raman spectroscopy1,2. In discovery, Raman spectroscopy is used to elucidate structural activity relationships3 and to optimise…

GPCRs: Cell based label-free assays in GPCR drug discovery

20 August 2013 | By Niklas Larsson, Linda Sundström, Erik Ryberg and Lovisa Frostne (AstraZeneca)

G protein-coupled receptors are one of the major classes of therapeutic targets for a broad range of diseases. The most commonly used assays in GPCR drug discovery measure production of second messengers such as cAMP or IP3 that are the result of activation of individual signalling pathways. Such specific assays…
