In order to further evaluate the extent to which particular 5-HT receptor subtypes (5-HT1, 5-HT2) might be involved in the behavioral effects of hallucinogenic drugs, rats were trained to discriminate mescaline (10 mg/kg i.p.) from saline and were given substitution (generalization) and combination (antagonism) tests with putatively selective serotonergic and related neuroactive compounds. The...
The effects of mescaline and LSD on the flash-evoked cortical potential (FEP) were determined in unrestrained rats with chronically-implanted electrodes. Systemic administration of mescaline or LSD significantly attenuated the primary component of the FEP at three stimulus intensities with the greatest effect observed 60-90 minutes following drug administration. The magnitude and specificity of...
The ability of serotonin2 (5-HT2) antagonists to block the excitatory effects of mescaline on the acoustic startle reflex were analyzed. Mescaline (20 mg/kg) caused a consistent increase in the amplitude of the acoustic startle reflex. This effect was blocked in a dose-related fashion by the 5-HT2 antagonist ritanserin (ED50 dose = 0.25 mg/kg IP). In contrast, even a high dose of ritanserin...
AbstractDurch Kondensation des Trimethoxy‐conitroethylbenzols (I) mit den aromatischen Aldehyden (II) werden neue Vorstufen (III) von Mescalinanalogen hergestellt.
Motor impairment, especially ataxia, is often mentioned as a 'side effect' of doses of psychoactive drugs which depress animal behaviour; it is difficult to determine it accurately from visual observation, but relatively few attempts have been made to measure it objectively and quantitatively. Mescaline, in moderate to large doses, can induce biphasic--depressant followed by stimulant--effects...

The modifications of behavior caused in the rat by a chronic oral administration of mescaline have been studied in three experimental situations. In the staircase maze mescaline accelerated the spontaneous decay on the conditioned reflex (memory decay) during the period without daily training. Only the results observed at 30 mg/kg/day of mescaline were statistically significant. In a T maze two...
A convenient one-step procedure to synthesize the title compounds (3a-v) by the reaction between 1, 2, 3-trimethoxy-5-(2-nitroethyl)benzene (1) and aromatic or heterocyclic aldehydes is reported. The obtained 1-aryl-2-nitro-3-(3, 4, 5-trimethoxyphenyl)propenes can easily be reduced to provide new mescaline derivatives. As an example, 1-(3-indolyl)-2-amino-3-(3, 4, 5-trimethoxyphenyl)propane...
The modifications of the rat behaviour caused by a chronic administration of mescaline were studied in two schedules of operant conditioning. In the "periodic conditioning" test, the schedule of reinforcement was changed from a fixed ratio to a fixed interval schedule. Mescaline (4 mg/kg/day and 10 mg/kg/day) caused no modification of the ability of the rat to adapt its behaviour to the new...
The death of an individual under the influence of mescaline is presented. Concentrations of the drug were 9.7, 70.8, and 1163 micrograms/mL or micrograms/g in blood, liver, and urine respectively.
