Labelled compounds form an essential part of drug discovery and development within the pharmaceutical industry. Novel iridium catalysts, developed by Kerr at WestCHEM since 2008, have introduced a step-change in the ability to label pharmaceutical candidate compounds with radioactive (tritium) or non-radioactive (deuterium) isotopes.
The catalysts are applicable to specific types of compounds that comprise approximately one-third of all drug candidates. Advantages of the catalysts include greater efficacy (less catalyst needed and higher yield of labelled product, giving cost savings), greater speed (efficiency savings), and a significant decrease in radioactive waste compared with previous methods (environmental and safety benefits).
Even since 2008, their adoption within the pharmaceutical industry has been extremely rapid; e.g., the multinational pharmaceutical company AstraZeneca now applies the Kerr methodology to 90% of their relevant candidate compounds. Additional impact has been achieved by Strem Chemicals who have been manufacturing and marketing the catalysts worldwide since October 2012. Even in that very short period, multiple sales have been made on three continents providing economic benefit to the company.
Since 2010, the Recreational Drugs European Network (Rednet), a collaborative, Europe-wide project originating at Hertfordshire, has monitored and documented markets, consumption patterns and risks of `new drugs'. In 2012 one of the university's researchers developed the integrated SMS and email (`Smail') rapid response service to deliver accurate, up-to-date drug intelligence to frontline workers, including doctors and police.

Smail researchers have also assisted addiction specialists to mitigate harm arising from newly emerging intravenous abuse of Tropicamide.
A new, more structured way of assessing the various harms done to individuals, families, communities and wider society by a range of legal and illegal drugs was first articulated by Professor David Nutt and colleagues at the University of Bristol. The "rational scale" they developed in the light of their research has stimulated extensive policy debate and informed drug classification in the UK and overseas. The research underpinning the scale has been disseminated through numerous public lectures and discussions and has stimulated worldwide media coverage. As a consequence, public awareness of drug harms has increased and public engagement in important debates about drugs has intensified.
The emergence of new psychoactive substances (NPS) in Europe over the last decade (including performance and image enhancing drugs), poses challenges to policy makers. These are substances which are frequently not controlled under law, and governments have struggled to address potential societal and health harms of use. We have analysed this drugs market, described the potential health harms of NPS, and generated evidence on effective intervention responses for some of these. Our findings have provided the necessary evidence to support the development of robust, responsive and predictive policy making at both national and international levels.
Techniques that can produce detailed chemical information rapidly and non-destructively for many forensic applications have been developed by Queen's University Belfast based on Raman analysis. The techniques have been adopted by the Forensic Science laboratory in Northern Ireland (FSNI) to trace the source of seized drugs, identify novel psychoactive substances ("legal highs") and study paint evidence. More than 2000 cases of supply/possession of ecstasy drugs, 947 paint casework samples and 100 'legal highs' have been analysed. Other law enforcement agencies are now adopting the methods developed at Queen's.
Nearly all solid dosage forms contain drugs in crystalline form; and all crystals have the potential to `morph', suddenly, into different forms which can affect the safety and efficacy of the medicinal product. A number of high-profile cases in which marketed medicines had to be withdrawn [Lee, et al., Annu. Rev. Chem. Biomol. Eng. 2011, 2, 259-280] led multinational drug company Pfizer to conclude that a greater understanding of polymorphism was required to enable drug product design for the 21st Century. The University of Greenwich pioneered methods to predict crystal behaviour on the shelf and during manufacture that were affordable, timely and effective. It enabled Pfizer to select the optimal polymorphic drug form and manage risk associated with uncontrolled solid-state transformations, thereby safeguarding patients and avoiding huge costs.
The health of people who inject illicit drugs, the formulation of harm-reduction policies, and the work of associated businesses and social enterprises have all benefited from the University's laboratory and practice research into the safety and efficacy of materials and equipment used in needle-exchange programmes. The research has informed the development of safer acids for injection preparation, safer injecting paraphernalia (e.g., spoons and filters) and an information film which has been distributed from needle exchanges on DVD and viewed over 50,000 times online. The research has led to enhanced support and protection for injecting drug misusers, and to advances in harm reduction in the UK, France and Canada.
Alzheimer's disease (AD) affects one in seven of the population over 60 years of age, and represents an increasing burden on worldwide medical and care resources. Treatments currently available are symptomatic. Despite pharmaceutical industry efforts there has been little indication of a marketable product for long-term treatment.
To address this problem, a joint venture was established in 2001 between the University of Aberdeen and TauRx Pharmaceuticals. A team was created of chemists, biologists, animal behaviourists, working together with a clinical trial team. A drug effective against the progress of AD based on the compound methylene blue was synthesised and scaled up within the Chemistry Department (led by Professor John Storey), with a quality that was proved acceptable through successful phase two clinical trials (2006-8), and is now used in phase three clinical trials which are due to complete in 2015. Several other drug candidates have also been developed and evaluated in pre-clinical and phase one clinical studies that show promise. Collaborations with commercial pharmaceutical companies have as a result led to the manufacture of significant quantities of drug medicines for TauRx Pharmaceuticals based on IP generated within the Chemistry Department and these drugs have been used in clinical trials and for named patient supply (c. 60 patients). This has resulted in increased commercial revenue for these companies and the creation of new employment.
Research by the School of Pharmacy played a key role in the 2008 regulatory approval of Janssen Pharmaceutica's HIV drug Intelence®. As a poorly soluble drug, Intelence® required specialist formulation and was the first formulation of its type to be approved by the FDA and EMA. Intelence® offers significantly improved clinical outcomes due to its efficacy in patients with HIV resistance. Global Intelence® sales in 2012 were $349M, with additional not-for-profit supplies to resource-limited countries. As a result of this landmark regulatory approval formulation development strategies at Janssen were adapted enabling a further poorly soluble drug to reach the market. Telaprevir, a second-generation Hepatitis C treatment (marketed as Incivek®, Incivo® & Telavic®), gained global regulatory approval in 2011. 2012 sales exceeded $1bn in the US alone.
Newcastle research is the driving force behind NewChem, a Newcastle University spin-out company which provides creative molecular design and synthetic/analytical services for the pharmaceutical/chemical industry. During 2008-2013, NewChem assisted Shire, a global pharmaceutical company, in the quest for new drugs for treating a range of therapeutic indications, including pain, cardiovascular disorders, ADHD and Alzheimer's disease. Since 2008, NewChem has provided employment for > 60 FTE's and achieved sales exceeding £1 million per annum.
