gnidimacrin/白血病

Gnidimacrin, a diterpene compound, isolated from the methanol extract of Stellera chamaejasme L, showed significant antitumor activities against mouse leukemia P-388 and L-1210 in vivo. At the dosages of 0.02-0.03mg/kg ip, the in increase in life span (ILS) was 70% and 80%, respectively. Gnidimacrin

Daphnane-type diterpene gnidimacrin (NSC 252940) shows significant antitumor activity against murine tumors and human tumor cell lines. This compound binds to and directly activates protein kinase C (PKC), arresting the cell cycle at the G(1) phase through inhibition of cdk2 activity in human K562

The daphnane-type diterpene gnidimacrin, isolated from the root of the Chinese plant, Stellera chamaejasme L., was found to strongly inhibit cell growth of human leukemias, stomach cancers and non-small cell lung cancers in vitro at concentrations of 10(-9) to 10(-10) M. On the other hand, even at

Daphnane-type diterpene gnidimacrin (NSC252940), isolated from a Chinese plant, exhibited antitumor activity against murine leukemias and solid tumors. At concentrations of 10(-9) to 10(-10) M, this agent strongly inhibited the growth of human tumor cell lines. In sensitive human leukemia K562

Five biologically active daphnane orthoesters have been isolated from Pimelea species (Thymelaeaceae). Four of these possessing antineoplastic activity against in vivo murine P-388 lymphocytic leukemia are gnidimacrin from P. ligustrina, simpleximacrin from P. simplex, linimacrin d and Pimelea
