(+)-Medicarpin, a pterocarpan, is an isoflavonoid compound derived from medicinal plant species such as Sophora japonica, Zollernia paraensis, Platymiscium yucatamun, Machaerium aristulatum, and Platymiscium floribundum. It potently inhibits osteoclastogenesis and facilitates bone healing and increased bone mass through osteoblast differentiation, mediated by the estrogen receptor (ER) β.

Pseudolaric acid B, a natural diterpenoid compound, is isolated from Pseudolarix kaempferi.

Longikaurin E ((-)-Longikaurin E) is a therapeutic agent for pancreatic cancer. It is isolated from Isodon adenolomus.

Jolkinolide B is a bioactive diterpene isolated from the roots of Euphorbia fischeriana Steud. Jolkinolide B induces apoptosis in cancer cells. Jolkinolide B can be used for studies on preventing and treating osteolysis.

7-xylosyltaxol is a taxol (Paclitaxel) derivative, has antineoplastic activity.

Rotundifuran is extracted from the fruit of Vitex rotundifolia. Rotundifuran inhibits cell cycle progression and induces apoptosis in human myeloid leukemia cells.

Terpendole I is a fungal metabolite that has been found in A. yamanashiensis.1 It is a weak inhibitor of acyl-coenzyme A:cholesterol acyltransferase (ACAT; IC50 = 145 μM) and is active against the bacteria B. cereus and B. subtilis (MICs = 100 μg/ml for both) but not S. aureus, P. aeruginosa, or K. pneumoniae (MICs = >200 μg/ml for all) or the fungus C. albicans (MIC = 200 μg/ml).1,2 It is cytotoxic to HeLa cells with an IC50 value of 52.6 μM.3 |1.

Crocin II (Crocetin gentiobiosylglucosyl ester) has anti-inflammatory and anti-apoptotic effects against gastric ischemia-reperfusion injury in rats, the effect of crocin is mainly mediated by reducing the protein expression of iNOS and caspase-3. Crocin II can ameliorate CCl4-induced liver injury via inhibition of inflammatory cytokines, caspase3 and oxidative stress along with modulation of liver metabolizing enzymes favoring elimination of CCl4 toxic metabolite. Crocin II has antihyperlipidemic effect, may be due to the inhibition of pancreatic lipase and crocin, and its metabolite, Crocin II , can improve hyperlipidemia. Crocin has antidepressant effects by increasing CREB, BDNF and VGF levels in hippocampus.
