Nodakenin acts as an AChE inhibitor that inhibits AChE activity in a dosedependent manner with an IC50 value of 84.7 μM. Nodakenin possesses neuroprotective, anti-allergic, antiaggregatory, antibacterial, and memory -enhancing effects. Nodakenin down-regulates the expression of the proinflammatory iNOS, COX-2, TNF-α, IL-6, and IL-1β genes in macrophages by interfering with the activation of TRAF6, thus preventing NF-κB activation.

Prunetin is a hydroxyisoflavone that is genistein in which the hydroxy group at position 7 is replaced by a methoxy group. It has a role as a metabolite, an EC 1.2.1.3 [aldehyde dehydrogenase (NAD(+))] inhibitor, an EC 1.3.1.22 [3-oxo-5alpha-steroid 4-dehydrogenase (NADP(+))] inhibitor and an anti-inflammatory agent. It is a member of 7-methoxyisoflavones and a hydroxyisoflavone. It is functionally related to a genistein. It is a conjugate acid of a prunetin-5-olate. Prunetin mediates anti-obesity/adipogenesis effects by suppressing obesity-related transcription through a feedback mechanism that regulates the expression of adiponectin, adipoR1, adipoR2, and AMPK. Prunetin and biochanin A are potent reducers of NF-κB and ERK activation, zonula occludens 1 tyrosine phosphorylation, and metalloproteinase-mediated shedding activity, which may account for the barrier-improving ability of these isoflavones.

Ligupurpuroside C can significantly inhibit lipid accumulation in HepG2 cell at the concentration of 50 umol/L.

Hypocrellin B has sonodynamic action to induce mitochondrial damage, survival inhibition, apoptosis and inhibit adhesion and migration of cancer cells. Photodynamic therapy with Hypocrellin B can remarkably induce apoptosis and inhibit adhesion and migration of cancer cells in vitro.

Neobavaisoflavone is a member of the class of 7-hydroxyisoflavones that is 7-hydroxyisoflavone with an additonal hydroxy group at position 4' and a prenyl group at position 3'. Isolated from seeds of Psoralea corylifolia, it exhibits inhibitory activity against DNA polymerase and platelet aggregation.
