Literature evidence |
Two structurally novel cytotoxic ent-kaurene diterpenoids, 13-methoxy-15-oxozoapatlin and 13-hydroxy-15-oxozoapatlin, were isolated from the root bark of Parinari curatellifolia, together with the known compound, 15-oxozoapatlin, on the basis of bioactivity-guided chromatographic fractionation and found to demonstrate broad-spectrum cytotoxic activity against a panel of cultured human cancer cell lines. |

Potency |
No antitumor activity was observed when athymic mice carrying KB cells were treated with 13-methoxy-15-oxozoapatlin. These data indicate that the cytotoxic activity of 13-methoxy-15-oxozoapatlin is mediated in part by covalent reaction with a cellular component (such as sulfhydryl-containing protein) by means of a Michael-type addition, and this results in the blockage of cell-cycle progression. |
