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.

Astragaloside III has anti-gastric ulcer effects, and exhibits strong growth-promoting effects in cultured GES-1 cells. Astragaloside III can effectively reduce cancer cell survival in vitro and inhibit the tumor growth in vivo, the potential mechanism is the induction of cell apoptosis signaling pathways, suggests that it provides a new therapeutic tool to treat breast cancer. Astragaloside III is a triterpenoid saponin that is cycloastragenol with a 2-O-beta-D-glucopyranosyl-beta-D-xylopyranosyl moiety attached at position 3 via a glycosidic linkage. It is a triterpenoid saponin and a disaccharide derivative. It is functionally related to a cycloastragenol.
