Sterekunthal B
- CAS No.: 475673-78-0
- Formula:C20H18O4
- Molecular Weight:322.35
InChIKey: NSNGIRMJTMEZBF-YJKZWKBDSA-N
SMILES: O=C[C@@]1([C@@]23C(C(C4=CC=CC=C4C3=O)=O)=C[C@@]5([H])[C@]1([H])CC[C@]5(O2)C)C
Biological Activity: 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[1][2][3].
