Pyrimidinylpiperazine

1-(2-Pyrimidinyl)piperazine (1-PP, 1-PmP) is a chemical compound and piperazine derivative. It is known to act as an α2-adrenergic receptor antagonist, and as a 5-HT1A receptor partial agonist to a much lesser extent. It does not appear to have any significant affinity for the D2 or α1-adrenergic receptors.
