    • The invention relates to compounds of formula I 1 in which R1, R2, R3, R4, R5, X1, X2, X3, X4, X5 and Y are defined in the specification. The compounds of formula I and II inhibit cyclin-dependent kinases (CDKs) and other kinases (KDR), have cytostatic actions, and are suitable for treating tumors. The compounds of formula I and II are obtainable by extracting the plant Uvaria klaineri, PLA 100484, by cell cultures of the plant Uvaria klaineri, or by chemical synthesis. The invention relates to a method for preparing the compounds of formula I and II, to the use of the compounds for producing a pharmaceutical for the treatment of malignant disorders and of diseases which may be treated by inhibition of CDKs and KDR, and also to pharmaceutical compositions comprising at least one compound of the formula I or II.
    • 本发明涉及其中R1,R2,R3,R4,R5,X1,X2,X3,X4,X5和Y在本说明书中定义的式I化合物。 式I和II的化合物抑制细胞周期蛋白依赖性激酶(CDKs)和其他激酶(KDR),具有细胞抑制作用,并且适用于治疗肿瘤。 式I和II化合物可以通过植物Uvaria klaineri的细胞培养物提取植物Uvaria klaineri,PLA 100484,或通过化学合成获得。 本发明涉及一种制备式I和II化合物的方法,该化合物用于制备用于治疗恶性疾病的药物和可通过抑制CDK和KDR治疗的疾病,以及制剂 组合物,其包含至少一种式I或II的化合物。
