A diphyllin glycoside called cleistanthin A was isolated from the tropical plant Cleistanthus collinus and its anticancer potential was assessed. This compound showed preferential cytotoxicity in several tumor cell lines. The GI50 values for normal cell lines were between 10(-6) and 10(-7) M while
Cleistanthin A is a novel anticancer agent isolated from Cleistanthus collinus (Rox B). It caused chromatid aberrations in a dose dependent manner. However, the concentrations that induced the aberrations, neither affected viability nor induced DNA strand breaks. Only at higher concentrations and
BACKGROUND
Cleistanthins A and B are isolated compounds from the leaves of Cleistanthus collinus Roxb (Euphorbiaceae). This plant is poisonous in nature which causes cardiovascular abnormalities such as hypotension, nonspecific ST-T changes and QTc prolongation. The biological activity predictions
Cleistanthin B is a potential anticancer agent isolated from the tropical plant Cleistanthus collinus. We have previously shown that cleistanthin B is clastogenic and induces micronuclei formation and chromosomal aberrations. We now show that this compound inhibits DNA synthesis in Chinese hamster
