| Name | Doxapram |
| Description | Doxapram (Dopram) is a respiratory stimulant that inhibits TASK-1, TASK-3, and TASK-1/TASK-3 heterodimer channels and is used to study ventilatory failure caused by apnea of prematurity and exacerbation of chronic obstructive pulmonary disease. |
| In vitro | Doxapram inhibits TASK-1 (EC50=410 nM), TASK-3 (EC50=37 μM), TASK-1/TASK-3 (EC50=9 μM) heterodimeric channel function. Doxapram also evoked 3H overflow in a concentration dependent manner, and Doxapram-evoked release was inhibited by the Ca2+ channel blocker nifedipine (5 mM). [1]
Doxapram (1-100 mM) caused rapid, reversible and dose-dependent inhibitions of K+ currents recorded in type I cells (IC50=13 mM). Doxapram was also seen to directly inhibit Ca(2+)-independent K+ currents. Doxapram was a more potent inhibitor of the Ca(2+)-activated K+ currents recorded under control conditions. [2] |
