periploca/白血病

Six pregnane glycosides and three cardenolides were isolated as differentiation inducers using mouse myeloid leukemia (Ml) cells from Periplocae Radicis Cortex (bark of Periploca sepium BGE., Asclepiadaceae). The cardenolides showed much higher activities than the pregnane glycosides. Besides these

BACKGROUND During a screening of Chinese plants traditionally used for the treatment of cancer and related diseases, extracts of the root bark of Periploca sepium Bunge showed strong cytotoxic activity. OBJECTIVE Isolate and identify cytotoxic compounds from P. sepium and investigate the effects and

OBJECTIVE Cardenoliddes are steroid glycosides which are known to exert cardiotonic effects by inhibiting the Na(+)/K(+)-ATPase. Several of these compounds have been shown also to possess anti-tumor potential. The aim of the present work was the characterization of the tumor cell growth inhibition
