Digiferruginol has cytotoxic activity. Digiferruginol and hederagenin show weak effect on porcine respiratory and reproductive syndrome virus (PRRSV) with an IC50 value of 80.5 ± 16.9 uM(SI = 19.9) and 43.2 ± 7.4 uM (SI = 13.1), respectively.

25-Hydroxycholesterol is a steroid derivative that suppresses the cleavage of sterol regulatory element binding proteins (SREBPs).

The peptide region containing residues 390-404 in Activated Protein C (APC) is essential for anticoagulant activity and is available for interaction with antibodies or with other proteins, such as the macromolecular substrates Factors Va or VIIIa. APC regulates blood coagulation by proteolytic inactivation of the blood coagulation cofactors Va and VIIIa.
