Cytisinicline (Sophorine), an alkaloid, is found naturally in several plants.

(-)-Sparteine sulfate pentahydrate ((-)-Sparteine Sulfate) is a class 1a antiarrhythmic agent and sodium channel blocker capable of chelating bivalent calcium and magnesium.

Sparteine is a class 1a antiarrhythmic agent, a sodium channel blocker. The deficient debrisoquine hydroxylation of Sparteine is due to the absence of P-450IID1 protein in the livers of poor metabolizers.

Dalbergioidin exhibits tyrosinase inhibitory activity with an IC50 of 20 mM. It shows a melanin biosynthesis inhibition zone in the culture plate of Streptomyces bikiniensis that has commonly been used as an indicator organism. Dalbergioidin protects MC3T3-E1 osteoblastic cells against H2O2-induced cell damage through activation of the PI3K/AKT/SMAD1 pathway, suggests that it may be useful in bone metabolism diseases, particularly osteoporosis. Dalbergioidin also ameliorates doxorubicin-induced renal fibrosis by suppressing the TGF-β signal pathway.
