Implementation of high-throughput quality control processs within compound management

31 August 2011 | By Jerome Giovannoni and J.M. Peltier, Novartis

The constant growth of compound collections, combined with screening efforts on more challenging targets, is creating an increasing demand for quality control in order to ensure the integrity of the compound solutions being tested. This is true throughout the early drug discovery pipeline, from hit identification to lead nomination. Novartis…

Application of deep UV resonance raman spectroscopy to bioprocessing

20 June 2011 | By Lorna Ashton and Royston Goodacre, School of Chemistry, Manchester Interdisciplinary Biocentre, University of Manchester

In recent years, Raman spectroscopy has been successfully applied to bioprocessing, including industrial processes. Raman studies have typically been aimed at measuring accurately both product yields and the presence of secondary products; including glucose and ethanol levels as well as secondary metabolites present in complex non-fractionated fermentation broths1,2. However, Raman…

Authentication of medicines using Raman spectroscopy

16 February 2011 | By Sulaf Assi, University of Hertfordshire, and Robert Watt & Tony Moffat, The School of Pharmacy, University of London

Raman spectroscopy offers a rapid and non-destructive technique for the identification of counterfeit medicines. Handheld Raman instruments offer the advantages of carrying the laboratory to the sample and giving a rapid pass or fail answer for the medicine inspected. It can identify a medicine regardless of its physical form as…

Raman spectroscopy and cancer cells

19 August 2010 | By Andrew Riches, Professor of Experimental Pathology, School of Medicine, University of St. Andrews and Co-authors: C. Simon Herrington, School of Medicine Kishan Dholakia, Elisabetta Canetta, Antonia Carruthers, Michael Mazilu, Anna Chiara de Luca, School of Physics & Astronomy Chris Goodman, Greg Kata, Nabi Ghulam, Kadi Nourdin, Department of Urology, Ninewells Hospital & Medical School, Dundee

Raman spectroscopy has the potential to provide diagnostic information to the clinician. The technique has a number of advantages allowing individual cells to be interrogated without staining. With further developments in technology, the surgeon will be able to rapidly acquire accurate diagnostic information at the time of operation using fibre…

Polymorph screening in pharmaceutical development

19 August 2010 | By Professor Alastair J. Florence, Solid-State Research Group, Strathclyde Institute of Pharmacy and Biomedical Sciences, University of Strathclyde

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), is of considerable importance when trying to achieve consistent product quality during the manufacture of pharmaceutical solids and solid dosage…

Raman spectroscopy for the analysis of drug products and drug manufacturing processes

9 May 2010 | By Prof. Thomas De Beer, Assistant-Professor, Process Analytical Technology, Faculty of Pharmaceutical Sciences, University of Ghent

This article aims at supplying a concise overview on the application of Raman spectroscopic analysis methods within the pharmaceutical drug product manufacturing world. Firstly, there will be a focus on the rapid and nondestructive off-line analysis feasibility of Raman spectroscopy for final drug products. Herewith, several possible sources of error…

A sensitive and selective vibrational spectroscopy technique in life sciences

12 December 2009 | By

At present, the relevance of Raman Spectroscopy (RS) as an analytical tool in pharmaceutical sciences is increasingly obvious. RS is a mode of vibrational spectroscopy based on inelastic scattering of laser light and, like infrared spectroscopy (IR), provides detailed molecular structure information (see Figure 1A). However, contrary to IR, it…
