Yellow Solid
Definition
ChEBI: TRAM-34 is an organochlorine compound.
Biological Activity
Highly selective blocker of intermediate conductance Ca 2+ -activated K + channels (IK Ca 1, K Ca 3.1) (K d = 20 nM). Exhibits 200-1500-fold selectivity over K V , BK Ca , SK Ca , Na + , CRAC and Cl - channels. Suppresses the reactivation of lymphocytes by mitogenic stimuli.
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,.
