Worldwide, there are plants known as psychoactive plants that naturally contain psychedelic active components. They have a high concentration of neuroprotective substances that can interact with the nervous system to produce psychedelic effects. Despite these plants' hazardous potential, recreational use of them is on the rise because of their psychoactive properties. Early neuroscience studies relied heavily on psychoactive plants and plant natural products (NPs), and both recreational and hazardous NPs have contributed significantly to the understanding of almost all neurotransmitter systems. Worldwide, there are many plants that contain psychoactive properties, and people have been using them for ages. Psychoactive plant compounds may significantly alter how people perceive the world.
1. Acta Crystallogr Sect E Struct Rep Online. 2008 Oct 22;64(Pt 11):o2156. doi: 10.1107/S1600536808033850. 2,2,9-Trimethyl-2,3-dihydro-pyrano[2,3-a]carbazol-4-(11H)-one. Sridharan M, Prasad KJ, Zeller M. The title compound, C(18)H(17)NO(2), was prepared from 1-hydr-oxy-7-methyl-carbazole and 3,3-dimethyl-acrylic acid with trifluoro-acetic acid as the cyclization catalyst. The mol-ecules contain an essentially planar 6-methyl-indole unit. The second aromatic ring is significantly bent away from the plane of this unit, with maximum deviations of 0.171 (1) and 0.185 (1) Å for two of the C atoms. In the crystal structure, there are neither N-H⋯O hydrogen bonds nor π-π stacking between the aromatic sections of neighboring mol-ecules. There is only one weak C-H⋯O hydrogen bond and a number of weak C-H⋯π inter-actions. DOI: 10.1107/S1600536808033850 PMCID: PMC2959763 PMID: 21581016
