Testolactone
Testolactone is only found in individuals that have used or taken this drug. It is an antineoplastic agent that is a derivative of progesterone and used to treat advanced breast cancer. [PubChem]Although the precise mechanism by which testolactone produces its clinical antineoplastic effects has not been established, its principal action is reported to be inhibition of steroid aromatase activity and consequent reduction in estrone synthesis from adrenal androstenedione, the major source of estrogen in postmenopausal women. Based on in vitro studies, the aromatase inhibition may be noncompetitive and irreversible. This phenomenon may account for the persistence of testolactones effect on estrogen synthesis after drug withdrawal.

Momilactone B
Momilactone B is found in cereals and cereal products. Momilactone B is a constituent of Oryza sativa (rice) Momilactone B is an allelopathic agent produced from the roots of rice (Oryza sativa L.) (100 mg from 200 kg dry rice husk). It has been shown to be produced in high concentrations by the roots of rice seedlings. The production of momilactone B has also been induced in response to infection by blast fungus (Pyricularia oryzae) or irradiated with UV light. More recently is has been shown to be a potential chemotherapeutic agent against human colon cancer. The second step is the cyclization of syn-CDP to 9 -pimara-7,15-diene. This step is initiated by the elimination of the diphosphate group, a type A cyclization. The genes encoding for the type A cyclase were found by Otomo et al. in 2004. It is suggested that OsKS4, located on chromosome 4 (14.3cM) is one of the genes responsible for phytoalexin biosynthesis. After UV-radiation, OsKS4 mRNA levels rise drastically in response to the attack. Constituent of Oryza sativa (rice)
