Gymnestrogenin has a dual LXRα±/α2 antagonistic profile.

Inhibitor peptide that selectively disrupts binding of the AMPA receptor subunit GluA2 (at the C-terminal PDZ site) to protein interacting with C kinase (PICK1). Does not affect binding of GluA2 to GRIP or ABP and does not increase AMPA current amplitude or affect long term depression (LTD).

Senecionine n-oxide is the primary product of pyrrolizidine alkaloid biosynthesis in root cultures of Senecio vulgaris.
