• Design and Synthesis of C-Ring Lactone- and Lactam-Based Podophyllotoxin Analogues as Anticancer Agents

  A series of novel podophyllotoxin (PDT) analogues was synthesized in which the lactone moiety was shifted to C ring. Some of the derivatives were also synthesized with modified A ring. Analogues 23 and 25 exhibited potent in vitro cytotoxicity against colon cancer (CaCO2) cell line. p-Demethylated E-ring analogues exhibited better potency than the corresponding methylated analogues. These analogues showed toxicity comparable to PDT against human erythrocytes albeit at much higher concentrations (100 μg/ml) than their cytotoxicity values.

  合成了一系列新的蒽醌类（PDT）类似物，其中内酯部分被移至C环。一些衍生物的A环也进行了改造。类似物23和25在体外对结肠癌（CaCO2）细胞系表现出强的细胞毒性。去甲基化的E环类似物的效力优于相应的甲基化类似物。这些类似物对人红细胞的毒性与PDT相当，尽管浓度要高得多（100 μg/ml），才显示出其细胞毒性值。

  The present invention is directed to substituted 4H-chromenes, 2H-chromenes, chromans and analogs thereof, represented by the general Formula (I) wherein R 5 , A, B, X, Y, Z and dotted lines are defined herein. The present invention also relates to the discovery that compounds having Formula (I) are activators of caspases and inducers of apoptosis. Therefore, the activators of caspases and inducers of apoptosis of this invention can be used to induce cell death in a variety of clinical conditions in which uncontrolled growth and spread of abnormal cells occurs.

  本发明涉及被代替的4H-色烯、2H-色烯、色烷及其类似物，由通式（I）所表示，其中R5、A、B、X、Y、Z和虚线在此定义。本发明还涉及发现具有通式（I）的化合物是caspase的激活剂和凋亡的诱导剂。因此，本发明的caspase激活剂和凋亡诱导剂可用于诱导在各种临床情况下出现的异常细胞的无控制生长和扩散的细胞死亡。
