  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。

  Twenty-eight neoflavonoids have been prepared and evaluated in vitro against HIV-1. Antiviral activity was assessed on MT-2 cells infected with viral clones carrying the luciferase reporter gene. Inhibition of HIV transcription and Tat function were tested on cells stably transfected with the HIV-LTR and Tat protein. Seven 4-phenylchromen-2-one derivatives showed HIV transcriptional inhibitory activity but only the phenylchrome-2-one 10 inhibited NF-κB and displayed anti-Tat activity simultaneously. Compounds 10, 14, and 25, inhibited HIV replication in both targets at concentrations <25 μM. The assays of these synthetic 4-phenylchromen-2-ones may aid in the investigation of some aspects of the anti-HIV activity of such compounds and could serve as a scaffold for designing better anti-HIV compounds, which may lead to a potential anti-HIV therapeutic drug.

  已经制备并在体外评估了28种新黄酮类化合物对HIV-1的活性。抗病毒活性是在感染了带有荧光素酶报告基因的病毒克隆的MT-2细胞上进行评估的。HIV转录和Tat功能的抑制在稳定转染了HIV-LTR和Tat蛋白的细胞上进行测试。七种4-苯基色烯-2-酮衍生物显示出HIV转录抑制活性，但只有苯基色烯-2-酮10同时抑制了NF-κB并显示出抗Tat活性。化合物10、14和25在<25 μM的浓度下抑制了两种靶标中的HIV复制。这些合成的4-苯基色烯-2-酮的测定可能有助于研究此类化合物的抗HIV活性的某些方面，并可能作为设计更好抗HIV化合物的框架，从而导致潜在的抗HIV治疗药物的出现。
