Euphorbia factor L7b（Cat No.:I044839）is a lathyrane-type diterpenoid isolated from Euphorbia lathyris, a plant traditionally used in herbal medicine. Structurally, it features a multi-ring framework characteristic of lathyrane diterpenes, with several ester groups contributing to its lipophilicity and biological activity. Euphorbia factor L7b has shown promising anti-inflammatory and cytotoxic effects, likely through modulation of key signaling pathways such as NF-κB and induction of apoptosis. Its potent bioactivity makes it a subject of interest for anticancer and antiviral drug research. Due to potential toxicity, careful dosing and further pharmacological evaluation are required.
