Bufotenin is a tertiary amine that consists of N,N-dimethyltryptamine bearing an additional hydroxy substituent at position 5. It has a role as a hallucinogen and a coral metabolite. It is a tertiary amine and a tryptamine alkaloid. It is functionally related to a N,N-dimethyltryptamine.

Isopteropodine has antimicrobial activity, it shows strong apoptotic effects on acute leukaemic lymphoblasts, it also shows an ability to stimulate the immune system.

Bufotenidine is a member of tryptamines.

D-calycanthine has antifungal activity, it shows significant inhibitory activities against five plant pathogenic fungi Exserohilum turcicum, Bipolaris maydis, Alternaria solani, Sclerotinia sderotiorum, and Fusarium oxysportium. Calycanthine is the principal alkaloid of the plant family Calycanthaceae. It is an aminal, an organonitrogen heterocyclic compound and a calycanthaceous alkaloid. It derives from a hydride of a calycanine.

Pregnenolone is a 20-oxo steroid that is pregn-5-ene substituted by a beta-hydroxy group at position 3 and an oxo group at position 20. It has a role as a mouse metabolite and a human metabolite. It is a 3beta-hydroxy-Delta(5)-steroid, a 20-oxo steroid and a C21-steroid. It derives from a hydride of a pregnane. Pregnenolone is an endogenous steroid hormone for inhibition of M1 receptor and M3 receptor-mediated currents with IC50 of 11.4 μM and 6.0 μM, respectively. Pregnenolone has memory-enhancing effects, used in the treatment of fatigue, Alzheimer’s disease, trauma and injuries.

D-Tetrahydropalmatine is a organic cation transporter 1 (OCT1) inhibitor, it can obviously inhibit the uptake of monocrotaline (MCT) in MDCK-hOCT1 cells and isolate rat primary hepatocytes, and attenuate the viability reduction and LDH release of the primary cultured rat hepatocytes caused by MCT.

Geissoschizine methyl ether is a potent serotonin ₁A receptor agonist and candidate for amelioration of aggressiveness and sociality by yokukansan, it has third-generation antipsychotic-like actions at the dopamine and serotonin receptors. Geissoschizine methyl ether is a strong acetylcholinesterase (AChE) inhibitor, it inhibited 50% of AChE activity at concentrations of 3.7 ± 0.3 ug/mL. Geissoschizine methyl ether protects neurons from oxidative toxicity by shifting energy metabolism from mitochondrial respiration to glycolysis. Geissoschizine methyl ether has vasorelaxant effect, which is composed of two different mechanisms: endothelial dependency with nitric oxide and endothelial independency with voltage-dependent Ca(2+)-channel blocking.

Reserpine is an alkaloid found in the roots of Rauwolfia serpentina and R. vomitoria. It has a role as an adrenergic uptake inhibitor, an antihypertensive agent, a xenobiotic, a first generation antipsychotic, an EC 3.4.21.26 (prolyl oligopeptidase) inhibitor, a plant metabolite and an environmental contaminant. It is a methyl ester, a yohimban alkaloid and an alkaloid ester. It is functionally related to a reserpic acid. Reserpine is an inhibitor of multidrug efflux pumps, used as an antipsychotic and antihypertensive drug. Reserpine ameliorates Abeta toxicity in the Alzheimer's disease model in Caenorhabditis elegans, it can significantly delay paralysis and increase the longevity in this model.
