Biological Activities
Phoradendron liga, a species of mistletoe, has been identified as a source of significant biological activity through the isolation of a unique protein called ligatoxin B. This newly discovered 46-amino acid protein exhibits potent cytotoxic properties when tested against specific human cell lines. Specifically, research demonstrates its effectiveness against the U-937-GTB human lymphoma line and the multidrug-resistant ACHN renal adenocarcinoma line. As a member of the class 3 thionins, the protein possesses a specialized helix-turn-helix DNA-binding domain that likely drives its cell-killing capabilities. These findings suggest that the plant's chemical compounds could play a crucial role in developing new strategies to combat drug-resistant cancers.
Compounds
Conditions
Phoradendron liga produces a novel cytotoxic protein known as ligatoxin B that demonstrates significant therapeutic potential against specific cancer cells. This mistletoe-derived protein exhibits potent in vitro cytotoxic activities against the human lymphoma cell line U-937-GTB. Additionally, the protein effectively treats the primary multidrug-resistant renal adenocarcinoma cell line ACHN. Research indicates that ligatoxin B achieved an IC50 value of 1.8 microM when applied to the U-937-GTB lymphoma cells. The treatment of the ACHN renal adenocarcinoma line was also successful, showing an IC50 value of 3.2 microM.
