A fixed-ratio schedule of water reinforcement (FR-10) was used to examine the relative contributions of pharmacological and behavioral mechanisms in the development of tolerance to the disruptive effects of LSD and mescaline in the rat. Rats treated daily with LSD or mescaline before operant testing developed tolerance to the impairement of responding, while rats treated daily after each...
Mescaline, in concentrations of 5 x 10(-4) and 1 x 10(-3) M, produced negative chronotropic and positive inotropic responses in isolated, spontaneously beating rat atria. In tissues driven at a constant rate, the inotropic response was diminished greatly, indicating that the increment in the force of contraction was secondary to the reduction in rate. These chronotropic and inotropic responses...
Albino rabbits of either sex were anesthetized, and a cannula was implanted permanently into the lateral ventricle. About 1 week later, the distribution of [(14)C]mescaline and its deaminated metabolite, [(14)C]trimethoxyphenylacetic acid ([(14)C]TMPA) in 12 brain regions was examined at 15, 60, and 180 min after the intraventricular injection of [(14)C]mescaline (0.5 μmol in 0.05 ml...

The narcotic antagonist naloxone does not antagonize antinociception elicited in the rabbit by 100 microgram/kg of mescaline centrally administered, whereas pretreatment with 6-hydroxydopamine (6-OHDA) inhibits this mescaline effect. Stereotyped behavior of rabbits following central mescaline administration is also prevented by 6-hda pretreatment. Since 6-OHDA in known to produce a degeneration...
An examination of the effects of S-(-) and R-(+) 2-amino-1,2,3,4-tetrahydronaphthalene (2-AT) on mouse spontaneous activity and rabbit EEG has shown that the S-(-) enantiomer shows selective central effects similar to those of hallucinogens like mescaline. A stereochemical analysis of these results indicates that the structural relationship between mescaline, or other phenethylamine type...
AbstractDurch Reaktion von Mescalin (I) mit den Säurechloriden (II) und nachfolgende Reduktion mit Lithiumaluminiumhydrid gelangt man über (III) zu den Mescalin‐Homologon (IV).
Brain-cortex slices demethylate mescaline and p-methoxyacetanilide, a reference O-demethylating substrate, though the rate of demethylation of mescaline is about one third that of the reference substrate. The demethylase activity is localized mostly in the soluble supernatant (105 000 x g). It is purified 47-fold with respect to the demethylation of mescaline by ammonium sulfate precipitation...
Replacement of the 4-methoxy of mescaline with higher alkyl homologues or with bromine led to increased activity at serotonin receptors in a sheep umbilical artery preparation. This activity appears correlated with lipophilicity, as measured by 1-octanol-water partition coefficients, but drops off when the 4-substituent is about five atoms in length. It is suggested that 3,4,5-trisubhe...
