Isolated from neem (Azadirachta indica).

A P2X3 receptor antagonist.

A water insoluble terpene fatty acid used in the treatment of gastrointestinal ulcers; it facilitates the healing and function of mucosal tissue.

NCI: An anilinoquinazoline with antineoplastic activity. Gefitinib inhibits the catalytic activity of numerous tyrosine kinases including the epidermal growth factor receptor (EGFR), which may result in inhibition of tyrosine kinase-dependent tumor growth. Specifically, this agent competes with the binding of ATP to the tyrosine kinase domain of EGFR, thereby inhibiting receptor autophosphorylation and resulting in inhibition of signal transduction. Gefitinib may also induce cell cycle arrest and inhibit angiogenesis. (NCI Thesaurus)

From Geigeria.

A cyclohexanone from the essential oil of Juniperus communis L.; possibly a C12 derivative of elemene SESQUITERPENES; claim of it being terpene based on being a breakdown product of sesquiterpene.

From Geijera parviflora.
