The effect of ethanol in vitro on the binding of 35S-t-butylbicyclophosphorothionate to brain membranes was examined. Ethanol inhibited basal binding of 35S-TBPS both in potassium bromide- (KBr)- and potassium chloride (KCl)-containing assay media. Ethanol was, however, considerably weaker in reducing 35S-TBPS binding in buffers with 100 mM KCl. Ethanol had no effect on the inhibition of 35S-TBPS binding produced by GABA and pentobarbital in the presence of KBr or KCl, whereas it clearly altered the enhancement of 35S-TBPS binding produced by these drugs when the assay was carried out in buffers containing KCl.
研究了乙醇在体外对35S-叔丁基双环磷硫代酸酯与脑膜结合的影响。在含有溴化钾(KBr)和氯化钾(KCl)的测定介质中,乙醇均抑制35S-TBPS的基础结合。然而,在含有100 mM KCl的缓冲液中,乙醇降低35S-TBPS结合的能力要弱得多。在存在KBr或KCl的情况下,乙醇对GABA和戊巴比妥产生的35S-TBPS结合抑制没有影响,而当在含有KCl的缓冲液中进行测定时,乙醇明显改变了这些药物产生的35S-TBPS结合增强作用。
