3,4-dimethoxybenzoic acid is a member of the class of benzoic acids that is benzoic acid substituted by methoxy groups at positions 2 and 3. It has a role as an allergen and a plant metabolite. It derives from a hydride of a benzoic acid.

Uncarine C is a member of indolizines.

Toosendanin (TSN) was used as a digestive tract-parasiticide and agricultural insecticide in ancient China;TSN is a selective presynaptic blocker, a L-type Ca 2+ channel agonist and an effective antibotulismic agent, by interfering with neurotransmitter release through an initial facilitation followed by a subsequent depression. TSN has effects on the growth, cell cycle arrest, induction of apoptosis and the involved signaling pathway in human promyelocytic leukemia HL-60 cells.

Berbamine is a novel inhibitor of bcr/abl fusion gene with potent anti-leukemia activity and also an inhibitor of NF-κB. Berbamine may be the first ATP-competitive inhibitor of CaMKII γ, could be as a new type of molecular targeted agent through inhibition of the CaMKII γ activity for treatment of leukemia.Berbamine confers cardioprotection against I/R injury by attenuating [Ca(2+)inf(i) overloading and preventing calpain activation through the activation of the PI3K-Akt-GSK3β pathway and, subsequently, opening of the mitoK(ATP) channel. Berbamine is a bisbenzylisoquinoline alkaloid and a member of isoquinolines.

Corypalmine (IC50=128.0±10.5 uM) can inhibit prolyl oligopeptidase. (-)-Corypalmine shows inhibition activity against spore germination of some fungi.

N-methyltyramine is a member of tyramines. It has a role as a mouse metabolite. It is a conjugate base of a N-methyltyraminium.

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.

Perakine is an indole alkaloid having a ajmalan-type skeleton and characterised by a 17alpha-acetoxy group, a 21beta-methyl group, loss of the 1-methyl group with associated unsaturation at N(1)=C(2), and a 20alpha-formyl group in place of the 20beta-ethyl side-chain. It derives from a hydride of an ajmalan.

Rhynchophylline is a member of indolizines. It has a role as a metabolite.
