Cytisine is an organic heterotricyclic compound that is the toxic principle in Laburnum seeds and is found in many members of the Fabaceae (legume, pea or bean) family. An acetylcholine agonist, it is widely used throughout Eastern Europe as an aid to giving up smoking. It has a role as a phytotoxin, a nicotinic acetylcholine receptor agonist and a plant metabolite. It is an alkaloid, a lactam, an organic heterotricyclic compound, a bridged compound and a secondary amino compound. Cytisine is a nicotinic acetylcholine receptor agonist, has been widely used for central nervous system (CNS) diseases treatment. It is a partial agonist at alpha4/beta2 nAChRs, and a full agonist at alpha3/beta4 and alpha7 nAChRs, has antidepressant-like properties in several rodent models of antidepressant efficacy.

Aconine is a diterpene alkaloid with formula C25H41NO9 that is isolated from several Aconitum species. It has a role as a xenobiotic, a NF-kappaB inhibitor, a plant metabolite and a human urinary metabolite. It is a diterpene alkaloid, a tertiary alcohol, a secondary alcohol, a bridged compound, a pentol, an organic heteropolycyclic compound, a polyether and a tertiary amino compound. It derives from a hydride of an aconitane. Aconine can inhibit RANKL-induced osteoclast differentiation in RAW264.7 cells by suppressing NF-κB and NFATc1 activation and DC-STAMP expression. Aconine can attenuate hepatic fat degeneration of rats with fatty liver induced by high-fat diet through decreasing TG,TC deposit in liver. Aconine inhibits NF - κ B activation induced by ligands of nuclear factor kappa B receptor activators.

Yohimbine hydrochloride is an alpha 2-adrenoreceptor antagonist, blocking the pre- and postsynaptic alpha-2 adrenoreceptors and causing an increased release of noradrenaline and dopamine.It is an antagonist to xylazine hydrochloride-ketamine hydrochloride immobilization of white-tailed deer. Yohimbine has been used as a mydriatic and in the treatment of impotence. It is also alleged to be an aphrodisiac.

Pseudopelletierine is an azabicycloalkane alkaloid that is 9-azabicyclo[3.3.1]nonane substituted by a methyl group at position 9 and an oxo group at position 3. It is found in pomegranate trees. It has a role as a plant metabolite. It is an alkaloid, an azabicycloalkane, a cyclic ketone and a tertiary amino compound.

Anisodamine, an anticholinergic drug, has antishock effect, which is intimately linked to alpha7nAChR-dependent anti-inflammatory pathway. Anisodamine demonstrates a direct cardiac depressive action at the myocyte level, which may be related to, at least in part, NO production and cholinoceptor antagonism, it causes the changes of structure and function in the transmembrane domain of the Ca(2+)-ATPase from sarcoplasmic reticulum. Anisodamine, a vasoactive drug, can abate endogenous endotoxaemia subsequent to splanchnic vasoconstriction due to hypovolaemia, it alleviates inflammatory damage by significantly reducing the expressions of VEGF and ICAM-1, and shows significant protective effects in an animal model of infusion phlebitis. Anisodamine also inhibits shiga toxin type 2-mediated tumor necrosis factor-alpha production in vitro and in vivo. Scopolamine is a non subtype selective muscarinic and nicotinic acetylcholine receptor antagonist. Scopolamine is used in traditional Chinese medicine research for various diseases, mainly for improving microcirculation in shock state, and can also be used for organophosphate poisoning.

Notoginsenosides Fa and R4 show significant neurite outgrowth enhancing activities in human neuroblastoma SK-N-SH cells.

L-Cysteine inhibits insulin release via multiple actions on the insulin secretory process through H(2)S production. L-Cysteine administration limits ischemia-reperfusion injury through a mechanism that appears to be at least partially dependent on H2S synthesis. L-cysteine hydrochloride hydrate is a hydrate that is the monohydrate form of L-cysteine hydrochloride. It has a role as a flour treatment agent, an EC 4.3.1.3 (histidine ammonia-lyase) inhibitor and a human metabolite. It contains a L-cysteine hydrochloride.

Scopolamine hydrobromide is a non subtype selective antagonist of muscarinic and nicotinic cholinergic receptors. Scopolamine hydrobromide has antioxidant and anti-inflammatory activities.

L-dopa is an optically active form of dopa having L-configuration. Used to treat the stiffness, tremors, spasms, and poor muscle control of Parkinson's disease. It has a role as a plant growth retardant, an antiparkinson drug, a dopaminergic agent, a prodrug, a neurotoxin, a hapten, an allelochemical, an antidyskinesia agent, a mouse metabolite, a plant metabolite and a human metabolite. It is a L-tyrosine derivative, a dopa and a non-proteinogenic L-alpha-amino acid. Levodopa is the precursor to the neurotransmitters dopamine, norepinephrine (noradrenaline), and epinephrine (adrenaline), used to treat Parkinson's symptoms.

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