    Product Description

    THPP-1 is an inhibitor of phosphodiesterase 10A (PDE10A; Ki = 1 nM).1 It is selective for PDE10A over PDE1A-9A and PDE11A (Kis = 44->50,000 nM for all). THPP-1 (3 mg/kg) decreases the number of avoidances in the conditioned avoidance response test in rats and reduces MK-801-induced increases in locomotor activity in mice.2 It improves novel object recognition in rats when administered at doses of 0.3 and 1 mg/kg.

    WARNING This product is not for human or veterinary use.
