Biochem/physiol Actions

Taltirelin (TA-0910) is a thyrotropin-releasing hormone (TRH) mimetic with greatly enhanced brain-penetration, oral activity and stability. Taltirelin shortens the duration of pentobarbital-induced sleep (0.3-3 mg/kg po. or 0.03-0.3 mg/kg iv.), antagonizes reserpine-induced hypothermia (1 or 3 mg/kg po. or 0.1-0.3 mg/kg ip.), and enhances the spontaneous motor activity (30 mg/kg po.) in mice in vivo, while TRH produces these effects at about 100 times higher doses.

Effects of orally administered TA-0910, a new thyrotropin-releasing hormone (TRH) analog, on the central nervous system (CNS) were investigated and compared with those of TRH. TA-0910 shortened the duration of pentobarbital-induced sleep and antagonized reserpine-induced hypothermia at 0.3 mg/kg or
