JP1302 is a potent, selective, high affinity antagonist of the α2C-adrenoceptor, with a Kb of 16 nM and a Ki of 28 nM for the human α2C-receptor. JP1302 shows antidepressant and antipsychotic-like effects. JP1302 can be used for neuropsychiatric disorders and renal dysfunction research[1][2][3].
JP1302 shows about 100-fold higher affinity than for α2A or α2B[1].
JP1302 (1-10 μmol/kg) decreases immobility time in the FST to a level similar to that seen with 10-30 μmol/kg of the antidepressant Desipramine[1].
JP1302 (5 μmol/kg, once) is capable of complete reversal of the impairment in PPI induced in Sprague-Dawley rats by the psychotomimetic NMDA receptor antagonist, phencyclidine and similar results are found in Wistar rats[1].
JP1302 (3 mg/kg, IV, once) significantly ameliorates renal dysfunction[3].
