Usage

General Description

"(2R)-Pterosin B" is a naturally occurring chemical compound found in specific species of ferns, most notably the bracken fern. (2R)-Pterosin B is a sesquiterpene and forms part of the 'pterosins' family, which are known for their biological activities, such as cytotoxic, antifungal, and antibacterial properties. However, it is also reported to be possibly carcinogenic for humans when consumed in high amounts due to its cytotoxic properties, which means it has the potential to damage or kill cells. This chemical has been extensively studied for its potential medical applications and its impact on human and animal health.

Cytotoxic diterpenoids and sesquiterpenoids from Pteris multifida

Three new ent-kaurane diterpenoids, named pterokaurane M1-M 3 (1-3) and three new C14 pterosin-sesquiterpenoids, named multifidoside A-C (4-6), along with 18 known compounds, were isolated from the whole plants of Pteris multifida. The structures of 1-6 were established using spectroscopic methods, including extensive 2D NMR and CD analyses. Compounds 4 and 5 showed cytotoxicity against the HepG2 tumor cell line with IC50 values of less than 10 μM.
