U-99194
U-99194 (PNU-99194) is a selective, potent dopamine D3 receptor antagonist. U-99194 inhibits the activation of D3 receptor mediated by endogenously released dopamine or exogenous D3 agonists. U-99194 abrogates the IPSC-suppressive effect of the D3 agonist PD 128907 in rat hippocampal slices. U-99194 significantly suppresses Nicotine (HY-127019)-induced tremor in mice. U-99194 can be used for the study of dopamine D3 receptor-mediated motor disorders, particularly kinetic tremors.

U-99194 (1 μM, 15 min) prevents the cocaine-induced inhibition of monosynaptic inhibitory postsynaptic currents (IPSCs) evoked from stratum radiatum in CA1 pyramidal neurons of rat hippocampal slices[2].
U-99194 (1 μM) blocks the inhibitory effect of PD 128907 ( HY-100539) on the amplitude of monosynaptic IPSCs evoked from stratum radiatum in CA1 pyramidal neurons of rat hippocampal slices[2].
