1'-Hydroxymidazolam  (Synonyms: 咪达唑仑杂质1)

1'-Hydroxymidazolam is a primary active metabolite of Midazolam, and it is a neuronal depressant agent. 1'-Hydroxymidazolam could inhibit neuronal activity add to the effects of Midazolam^[1][2].

1'-Hydroxymidazolam (5?nM-1?μM) induces a significant inhibition of the action potential firing rate at concentrations of 100?nM or higher and causes a steady increase in the depression of network activity with increasing concentrations of up to 1?μM in neocortical slice cultures from wild-type mice^[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
