Evocarpine shows antimycobacterial, and vasorelaxant effects, it can inhibit Ca2+ influx through voltage-dependent calcium channels.

Yangambin is a selective antagonist of the cardiovascular effects of platelet activating factor (PAF); it has hypotensive effect, which is probably due to a peripheral vasodilatation that involves, at least, the inhibition the Ca2+ influx through voltage-gated Ca2+ channels. Yangambin has central nervous system activity, it presents a depressant activity in the open field, forced swimming and pentobarbital sleeping time tests.

Saikogenin D possesses a dual effect: an inhibition of A23187-induced PGE2 production without a direct inhibition of cyclooxygenase activity; and an elevation of [Ca2+]i that is attributed to Ca2+ release from intracellular stores. Saikogenin D has immunomodulatory effect, it can attenuate IL-6 production in LPS-stimulated alveolar macrophages of B6 more than in that of BALB.

7-O-Methyleriodictyol inhibits the maximum contractions induced by acetylcholine or oxytocin.
