Bignoniaceae Extract

Sterekunthal B is a naphthoquinone compound and antimalarial agent. Sterekunthal B can be isolated from plants of the Bignoniaceae family, including the root bark of Stereospermum colais. Sterekunthal B inhibits the growth of Chloroquine (HY-17589A)-sensitive Plasmodium falciparum strain PoW with an IC₅₀ of 23.3 μg/mL. Sterekunthal B also inhibits the growth of Chloroquine-resistant Plasmodium falciparum strain Dd2 with an IC₅₀ of 15.2 μg/mL. Sterekunthal B exhibits non-selective cytotoxicity toward endothelial cells. Sterekunthal B can be used in malaria-related research.

5-Hydroxy-6,7-dimethoxyflavone is an orally active inhibitor of ferroptosis (Ferroptosis). 5-Hydroxy-6,7-dimethoxyflavone inhibits H1N1 virus-induced ferroptosis by upregulating the expression of SLC7A11 and GPX4. 5-Hydroxy-6,7-dimethoxyflavone alleviates inflammatory responses and inhibits apoptosis by suppressing the activation of the NF-κB and p38 MAPK signaling pathways. 5-Hydroxy-6,7-dimethoxyflavone can be used in studies related to H1N1 influenza virus infection.

6-O-p-Hydroxybenzoylglutinoside acts as a selective NF-κB inhibitor that suppresses the transcriptional activity of TNF-α-activated NF-κB (IC₅₀=52.78 μM). 6-O-p-Hydroxybenzoylglutinoside shows no significant inhibitory activity against sEH, AChE, or BChE. 6-O-p-Hydroxybenzoylglutinoside is a caged chlorinated iridoid glycoside identified from the seeds of Catalpa bungei (Manchurian catalpa).
