1-(2-Pyrimidinyl)piperazine (1-PP, 1-PmP) is a chemical compound and piperazine derivative. It is known to act as an antagonist of the α₂-adrenergic receptor (K_i = 7.3–40 nM) and, to a much lesser extent, as a partial agonist of the 5-HT_1A receptor (K_i = 414 nM; E_max = 54%). It has negligible affinity for the dopamine D₂, D₃, and D₄ receptors (K_i > 10,000 nM) and does not appear to have significant affinity for the α₁-adrenergic receptors. Its crystal structure has been determined.
