We investigated in mice the effects of one of the principal metabolites of buspirone and gepirone, 1-(2-pyridinyl)-piperazine (1-PmP), on hypothermia and reduced locomotion induced by clonidine (0.25 and 0.06 mg/kg, respectively), tests related to brain alpha-adrenergic function. Both effects were

The pharmacokinetics and in vivo potency of 6-hydroxybuspirone (6-OH-buspirone), a major metabolite of buspirone, were investigated. The plasma clearance (47.3 +/- 3.5 ml/min/kg), volume of distribution (2.6 +/- 0.3 l/kg), and half-life (1.2 +/- 0.2 h) of 6-OH-buspirone in rats

A new fluorescent sensor was designed and synthesized from 5-nitro-1,2-dihydroacenaphthylene, n-butyl amine and 1-(2-pyridyl)piperazine. In DMF/H2O (3:1, v/v), the sensor showed excellent selectivity and sensitivity to Fe3+ with fast fluorescence enhancement and good anti-interference ability. The maximal fluorescence intensity was
