Abstract
It is now established that NO is a messenger molecule in mammals despite its high toxicity. As NO+ and CO are isoelectronic, it should not be unexpected that CO could also have a role as a messenger. CO is produced naturally in humans at a rate of between 3 and 6 cm3 per day, and this rate is increased markedly by certain inflammatory states and pathological conditions associated with red blood cell hemolysis. Over the last 10 years, the interest in the biological effects of CO has greatly increased, and it is now established in the medical literature that CO does have a major role as a signaling molecule in mammals. It is particularly active within the cardiovascular system, for example, in suppressing organ graft rejection and protecting tissues from ischemic injury and apoptosis. Recently it has been shown that metal carbonyls can also function as CO‐releasing molecules and provide similar biological activities. This opens the possibility to develop pharmaceutically important metal carbonyls.Keywords
