  • The Cheillistry of Peyote Al.Kaloids!
    The CheIllistry of Peyote Al.kaloids! GOVIND J. KAPADIA AND M. B. E. FAYEZ Department of Pharmacognosy and Natural Products, College of Pharmacy, Howard University, Washington, D.C. 20001 The fact that several publications, reporting new constituents and biogenetic pathways of peyote, have appeared since the publication of our latest review article (I)-and surely more to come-and the organization of this Symposium all testify that interest in peyote is still far from extinguished. In the lapse of only the past 18 months, fifteen additional constituents of peyote have been reported, bringing the total number of identified constituents of this resourceful cactus to 56 at the time of writing this article. The earliest chemical studies with peyote were made by Lewin (2) in 1888 who isolated the first crystalline constituent, namely the tetrahydroisoqui- noline alkaloid anhalonine (XXXVIII; for structures, cf. table 1). With the realization that the latter compound possessed no hallucinatory effects, vigorous research was continued to discover the active principle. The studies of Heffter (3-8) towards the end of the century resulted in the discovery of three additional tetrahydroisoquinolines, pellotine (XXXV), anhalonidine (XXX), and lophophorine (XLI) and the identification of mescaline (XVII), a il-phene- thylamine, as the hallucinogenic principle of the drug. In 1899, another alkaloid, anhalamine (XXI), was isolated by Kauder (9). Ernst Spath must be ac- credited for the structure elucidation and the synthesis of all these alkaloids, publishing his results in a series of reports from 1919 and extending the scope of his investigations to include alkaloids from other Cactaceae up to 1939 (10-28).

Objectives: This article aims to fully review pharmacokinetics and pharmacodynamics of mescaline, focusing on the in vivo and in vitro metabolic profile of the drug and its implications for the variability of response. Methods: Mescaline pharmacokinetic and pharmacodynamic aspects were searched in books and in PubMed (U.S. National Library of Medicine) without a limiting period. Biological effects of other compounds found in peyote were also reviewed. A R T I C L E H I S T O R Y Results: Although its illicit administration is less common, in comparison with cocaine and Cannabis, it has been extensively described in adolescents and young adults, and licit consumption often occurs in religious and therapeutic rituals practiced by the Native American Church.
