Biological Activity of TCS 1102

TCS 1102 is a potent, dual orexin receptor antagonist (Ki values are 0.2 and 3 nM for OX2 and OX1 receptors respectively).
IC50 value: 0.2 nM (Ki, OX2 receptor); 3 nM (Ki, OX1 receptor) [1]
Target: OX2 and OX1 receptor
TCS-1102 (10 and 20 mg/kg, i.p.) were found to decrease fear and anxiety in rats 14 days after exposure to footshock.Furthermore, TCS-1102 (10 mg/kg, i.p.) was found to have anxiolytic effects that were specific for HR when tested in the elevated T-maze. [2]
