Harmine
Definition:
(n.) An alkaloid accompanying harmaline (in the Peganum harmala), and obtained from it by oxidation. It is a white crystalline substance.
Example Sentences:
(1) However, in hepatocytes from phenobarbital treated rats, where the rate of harmine metabolism is increased about five times and the main metabolite is harmol glucuronide, phenolphthalein glucuronide inhibited the formation of the conjugate with a concomitant increase in free harmol.
(2) MAO substrate specificity to tyramine, benzylamine, and serotinin along with selective inhibition by harmine, pargyline, and clorgyline were used as indices of multiple enzymic forms.
(3) Aprotinin may decrease or increase the blood-brain barrier permeability of harmine.
(4) Nomifensine reduced the intensity of harmine-induced tremor.
(5) The data suggest that the integrity of the paleostriatum is more important than that of the neostriatum for the mediation of harmine tremor and its antagonism by dopaminergic agonists.
(6) Several naturally occurring aromatic amines especially 2-carboline derivatives such as harman, norharman, harmaline, harmalol, harmine and harmol are mutagenic and become more mutagenic to Salmonella typhimurium after nitrosation.
(7) The brain lesion technique was used to investigate the role of the paleostriatum and the nigro-neostriatum in harmine-induced tremor and in its antagonism by dopaminergic agonists, apomorphine, 1-dopa, piribedil, d- and l-amphetamine.
(8) Harmine (HA) induces a jumping behavior in rats when the central dopaminergic function has been activated.
(9) The brain lesion technique was used to destroy the ascending 5-hydroxytryptamine (5-HT) system at its cell bodies in the dorsal and medial raphe nuclei in order to assess the importance of 5-HT for the induction of harmine tremor and its antagonism by the dopaminergic agonists, L-DOPA, apomorphine and d-amphetamine.
(10) The beta-carboline harmine was found to facilitate lordosis behavior in ovariectomized rats primed with estradiol benzoate.
(11) The mutagenicities of other carboline derivatives such as harman, norharman, harmaline, harmalol, harmine, and harmol were studied.
(12) The partially competitive nature of inhibition by one of the more effective pairs, 2-methyl-harmine and harmine, was consistent with uptake of the beta-carbolines by the synaptosomal dopamine uptake system, as was the fact that the accumulation of 2-[14C]methyl-harmine was significantly reduced by low Na+ media and by nomifensine, a potent inhibitor of the dopamine transporter.
(13) at the peak of the harmine effect, tremors subside.
(14) In ethanol-withdrawn rats treated with harmine or LON-954 the frequency analysis of tremor revealed a narrow peak frequency at about 12 Hz, which was neither the characteristic frequency of ethanol withdrawal tremor (6 Hz) nor that of harmine or LON-954 (10 Hz).
