Metal Carbonyls. A New Class of Pharmaceuticals?

by Brian Mann

In recent years, it has become apparent that CO is an important signalling molecule in mammals, and is probably as important as NO. Perhaps one of the clearest applications of CO gas in medicine is the recent paper in Nature Medicine describing that it suppresses organ graft rejection and arteriosclerotic lesions associated with chronic graft rejection and with balloon injury. (L.E. Otterbein, B.S. Zuckerbraun, M. Haga, F. Liu, R. Song, A. Usheva, C. Stachulak, N. Bodyak, R.N. Smith, E. Csizmadia, S. Tyagi, Y. Akamatsu, R.J. Flavell, T.R. Billiar, E. Tzeng, F.H. Bach, A.M.K. Choi and M.G. Soares, Nature Medicine, 2003, 9, 183-190.) Carbon monoxide acts on the cardiovascular system and produces a wide range of responses including:-

We have shown that metal carbonyls can perform many of these functions, presumably acting as CO releasing molecules. Working with Dr. Roberto Motterlini and Professor Colin Green at Northwick Park Hospital, London, we have shown that [Ru(CO)3Cl(glycinate)]
