“4 Isoflurane also potentiated responses to taurine , a partial agonist at the glycine receptor.”
“The EC50 concentration decreased from a control value of 1.6 ± 0.2 to 0.9 ± 0.1 mM taurine in the presence of 305 μm isoflurane , while the maximum response to taurine increased from 47 ± 2 to 59 ± 2% of the maximum response to glycine.”
