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 (Ki = 7.3–40 nM)[1] and, to a much lesser extent, as a partial agonist of the 5-HT1A receptor (Ki = 414 nM; Emax = 54%).[2][3] It has negligible affinity for the dopamine D2, D3, and D4 receptors (Ki > 10,000 nM) and does not appear to have significant affinity for the α1-adrenergic receptors.[4] Its crystal structure has been determined.[5]
Derivatives
A number of pyrimidinylpiperazine derivatives are drugs, including:
- Buspirone – anxiolytic
- Dasatinib – anticancer agent
- Eptapirone – anxiolytic
- Gepirone – anxiolytic
- Ipsapirone – anxiolytic
- Piribedil – antiparkinsonian agent
- Revospirone – anxiolytic
- Tandospirone – anxiolytic
- Tirilazad – neuroprotective agent
- Umespirone – anxiolytic
- Zalospirone – anxiolytic
The anxiolytics are also classified as azapirones due to the azaspirodecanedione moiety in their structures. 1-PP is a common metabolite of most or all of the listed agents.[1][6] Alnespirone, binospirone, and enilospirone, despite being azapirones, are not piperazines and therefore do not metabolize to 1-PP, and while perospirone and tiospirone are piperazines, they are instead benzothiazole-substituted piperazines and do not metabolize to 1-PP either.
