Propofol 21-29 5-hydroxytryptamine receptor 3A Homo sapiens 39-45 18292429-3 2008 To investigate the molecular mechanisms responsible for these contrasting actions, we examined the kinetics of the action of propofol and its lesser hydrophobic derivatives 2-isopropylphenol and phenol on human 5-HT3A receptors. Propofol 125-133 5-hydroxytryptamine receptor 3A Homo sapiens 211-217 18292429-6 2008 RESULTS: When applied in equilibrium (60 s before and during the 5-HT pulse), propofol inhibited human 5-HT3A receptors (IC50 = 18 +/- 1.0 microM). Propofol 78-86 5-hydroxytryptamine receptor 3A Homo sapiens 103-109 18292429-12 2008 CONCLUSIONS: At least two separate inhibitory actions on 5-HT3A receptors could be identified for propofol, whereas the enhancing action seen for the two related smaller phenol derivatives could no longer be detected. Propofol 98-106 5-hydroxytryptamine receptor 3A Homo sapiens 57-63 17669396-0 2007 Inhibition of human 5-HT(3A) and 5-HT(3AB) receptors by etomidate, propofol and pentobarbital. Propofol 67-75 5-hydroxytryptamine receptor 3A Homo sapiens 20-27 17669396-4 2007 Because the half-maximal inhibitory concentrations for etomidate, propofol and pentobarbital in 5-HT(3A) and 5-HT(3AB) receptors were all above their respective anaesthetic concentrations, the results of our study suggest that neither 5-HT(3) receptor subtype contributes to the anaesthetic actions of etomidate, propofol or pentobarbital.
