Application

TRAM-34 has been used to study its effect on the prevention of vascular restenosis after balloon angioplasty.

Biochem/physiol Actions

TRAM-34 exhibits 100-fold selectivity (Kd = 20 nM) for IKCa1 channels over other K+ channels (Charybdotoxin, Kd = 5 nM, Clotrimazole, Kd = 70 nM; Nitrendipine Kd = 900 nM). Furthermore, TRAM-34 is known to suppress the activation of human T lymphocytes,.
TRAM-34 is a potent inhibitor of the intermediate-conductance Ca2+-activated K+ channel.

Features and Benefits

This compound is featured on the Potassium Channels page of the Handbook of Receptor Classification and Signal Transduction. To browse other handbook pages, click here.

Preparation Note

TRAM-34 is soluble in DMSO at 2 mg/ml. However, it is insoluble in water.
