The ability to render a patient unconscious and insensible to pain made modern surgery possible and general anaesthetics have become both indispensible as well as one of the most widely used class of drugs. Their extraordinary chemical diversity, ranging from simple chemically inert gases to complex barbiturates, has baffled pharmacologists, and ideas about how they might work have been equally diverse. Until relatively recently, thinking was dominated by the notion that anaesthetics acted \u2018nonspecifically\u2019 by dissolving in the lipid bilayer portions of nerve membranes. While this simple idea could account for the chemical diversity of general anaesthetics, it has proven to be false and it is now generally accepted that anaesthetics act by binding directly to sensitive target proteins. For certain intravenous anaesthetics, such as propofol and etomidate, the target has been identified as the GABA<jats:sub>A<\/jats:sub> receptor, with particular subunits playing a crucial role. For the less potent inhalational agents, the picture is less clear, although a relatively small number of targets have been identified as being the most likely candidates. In this review, I will describe the work that led up to the identification of the GABA<jats:sub>A<\/jats:sub> receptor as the key target for etomidate and propofol and contrast this with current progress that has been made in identifying the relevant targets for other anaesthetics, particularly the inhalational agents.<\/jats:p><jats:p><jats:italic>British Journal of Pharmacology<\/jats:italic> (2006) <jats:bold>147<\/jats:bold>, S72\u2013S81. doi:<jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"doi\" xlink:href=\"10.1038\/sj.bjp.0706441\">10.1038\/sj.bjp.0706441<\/jats:ext-link><\/jats:p>","DOI":"10.1038\/sj.bjp.0706441","type":"journal-article","created":{"date-parts":[[2006,1,10]],"date-time":"2006-01-10T10:50:21Z","timestamp":1136890221000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":261,"title":["Molecular targets underlying general anaesthesia"],"prefix":"10.1111","volume":"147","author":[{"given":"Nicholas P","family":"Franks","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2009,2,2]]},"reference":[{"key":"e_1_2_13_2_1","doi-asserted-by":"publisher","DOI":"10.1124\/mol.59.4.814"},{"key":"e_1_2_13_3_1","doi-asserted-by":"publisher","DOI":"10.1124\/mol.65.1.68"},{"key":"e_1_2_13_4_1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.94.20.11031"},{"key":"e_1_2_13_5_1","doi-asserted-by":"publisher","DOI":"10.1074\/jbc.M005460200"},{"key":"e_1_2_13_6_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMra021261"},{"key":"e_1_2_13_7_1","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.1153-05.2005"},{"key":"e_1_2_13_8_1","doi-asserted-by":"publisher","DOI":"10.1097\/00000542-199206000-00013"},{"key":"e_1_2_13_9_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1476-5381.1996.tb15430.x"},{"key":"e_1_2_13_10_1","doi-asserted-by":"publisher","DOI":"10.1038\/300487a0"},{"key":"e_1_2_13_11_1","doi-asserted-by":"publisher","DOI":"10.1038\/310599a0"},{"key":"e_1_2_13_12_1","doi-asserted-by":"crossref","first-page":"662","DOI":"10.1038\/333662a0","article-title":"Volatile general anaesthetics activate a novel neuronal K+ current","volume":"333","author":"FRANKS N.P.","year":"1988","journal-title":"Nature"},{"key":"e_1_2_13_13_1","doi-asserted-by":"publisher","DOI":"10.1038\/367607a0"},{"key":"e_1_2_13_14_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1476-5381.1991.tb12479.x"},{"key":"e_1_2_13_15_1","first-page":"628","article-title":"Positive modulation of human GABAA and glycine receptors by the inhalation anesthetic isoflurane","volume":"44","author":"HARRISON N.L.","year":"1993","journal-title":"Mol.
