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.

Diabetic ketoacidosis (DKA) causes brain injuries in children ranging from subtle to life-threatening. Previous studies suggest that DKA-related brain injury may involve both stimulation of Na-K-Cl cotransport and microglial activation. Other studies implicate the Na-K-Cl cotransporter and the Ca-activated K
