Future Directions

It has been argued8 that general anesthesia cannot be adequately explained until there is a clearer understanding of the phenomenon of consciousness and the associated states of awareness and sleep. Examination of individual components of anesthesia, immobility, antinociception, and amnesia underlines the need for an integrated approach to such understanding since, for instance, pain can lead to increased awareness. The search for discrete mechanisms for anesthetics of all three classes - inhalation, parenteral and local - is gradually advancing but has yet to be used for the de novo discovery of new anesthetic agents. The ability to reconcile the unitary hypothesis of anesthesia with multiple molecular targets will be an interesting research challenge and will require that the sophisticated molecular modeling of anesthetic interactions with membranes extends beyond artificial, reductionistic constructs,3,10,16,17,25,26 that, although eminently interesting, add little to advancing research in the area without a consideration of the effects of anesthetics in more complex native membrane systems.

L J S Knutsen began his research career at Glaxo in Ware, Herts, UK having completed an MA in chemistry at Christ Church, Oxford, in 1978. While at Glaxo, he completed a PhD in nucleoside chemistry joining Novo Nordisk in Denmark in 1986. There he led the project that identified tiagabine, a marketed anticonvulsant acting by blocking GABA uptake. In 1997, he joined Vernalis (Cerebrus) in the UK, initiating the adenosine A2A antagonist project that led to V2006, currently in clinical trials with Biogen-IDEC for Parkinson's disease. He joined Ionix Pharmaceuticals Ltd., in Cambridge, UK in 2002 as Director of Chemistry. Dr Knutsen joined the CNS Medicinal Chemistry group at Cephalon Inc., in 2006. He has over 35 peer-reviewed publications and 18 issued US patents.

Michael Williams, PhD, DSc, received his PhD (1974) from the Institute of Psychiatry and his DSc degree in pharmacology (1987) both from the University of London. Dr Williams has worked in the US-based pharmaceutical industry for 30 years at Merck, Sharp and Dohme Research Laboratories, Nova Pharmaceutical, CIBA-Geigy and Abbott Laboratories. He retired from the latter in 2000 and after serving as a consultant with various biotechnology/ pharmaceutical/venture capital companies in the US and Europe, joined Cephalon, Inc. in West Chester, in 2003 where he is vice president of Worldwide Discovery Research. He has published some 300 articles, book chapters, and reviews, and is an adjunct professor in the Department of Molecular Pharmacology and Biological Chemistry at the Feinberg School of Medicine, Northwestern University, Chicago, IL.

Blood Pressure Health

Blood Pressure Health

Your heart pumps blood throughout your body using a network of tubing called arteries and capillaries which return the blood back to your heart via your veins. Blood pressure is the force of the blood pushing against the walls of your arteries as your heart beats.Learn more...
