Neostenine shows significant antitussive activity.

1. Protostemonine has anti-inflammatory activity, it effectively attenuates LPS-induced inflammatory responses in vitro and in vivo; the beneficial effects are associated with the decreased phosphorylation of MAPK and AKT and the reduced expression of pro

(E)-Ferulic acid methyl ester (Methyl (E)-ferulate) is a possible inhibitor of the mitogen activated phosphor kinase pathway, it could be a potential anti-inflammatory agent isolated for the first time in medicinal plant S. tuberosa. (E)-Ferulic acid methyl ester has promising anthelmintic activity against Haemonchus contortus.

Bisdehydroneotuberostemonine shows significant inhibitory effect on lipopolysaccharide-induced nitric oxide production in BV2 microglia at 100 uM.

Dehydro-δ-tocopherol shows antioxidant capacities.

Stilbostemins N may exhibit moderate antibacterial activities.

1. Tuberostemonine (Tuberstemonine) exhibits relatively higher intestinal permeabilities. 2. Tuberostemonine acts in part as an open-channel blocker at the crayfish neuromuscular junction.

Stilbostemin A, stilbostemin B , stilbostemin D , stilbostemin F , and stilbostemin G show structure-dependent inhibition of leukotriene biosynthesis with IC(50) values ranging from 3.7 to >50 microM.
