  Growth-Inhibitory Activities of Benzofuran and Chromene Derivatives toward Tenebrio molitor

  摘要：

  Growth-inhibitory activities of selected natural benzofurans (4-9), trans-cinnamic acid derivatives (10-13), chromene compounds (14 and 16), and some semisynthetic derivatives were determined in last instar larvae of Tenebrio molitor via topical administration in Me2CO. The mast inhibitory of the tested compounds were 3-gamma,gamma-dimethylallyl-p-coumaric acid (10) and the benzofuran derivative 12-(p-cumaroyloxy)-tremetone (5), the former compound acting on the pupae and the latter on the last instar larvae. Several developmental deficiencies were observed, and some structure-activity relationships are discussed.

  Structure−Antimutagenic Activity Relationship Study of Plicatin B

  摘要：

  A systematic structure-activity relationship study of plicatin B (1), an antimutagenic constituent of Psoralea juncea, was undertaken with a view toward elucidating its chemical mode of action and possibly optimizing its antimutagenic activity during the process. Compound 1 and its related analogues were examined for their antimutagenic activity against mutations induced by ethyl methanesulfonate, a direct acting mutagen and alkylating agent, in Salmonella typhimurium strain TA100, utilizing the modified Ames test protocol. The dihydro analogue 3 resulting from saturation of the conjugated alkene double bond of 1 was found to exhibit reduced cytotoxicity and enhanced efficacy relative to the parent compound. This result serves preliminarily to exclude a Michael acceptor role of the alpha,beta-unsaturated carbonyl moiety in connection with its antimutagenic activity.

  have antitumor activities and can selectively inhibit the AKR1C3 enzyme, overexpressed in hormone-dependent prostate and breast tumors. Thus, in an attempt to develop new cytotoxic inhibitors against these cancers, three prenylated compounds, artepillin C, drupanin and baccharin, were isolated from green propolis to synthesize new derivatives via coupling reactions with different amino acids. All obtained

  乳腺癌在女性中的发病率和死亡率最高，而前列腺癌在男性中的发病率第二高。研究表明，巴西绿蜂胶中的化合物具有抗肿瘤活性，可以选择性地抑制在激素依赖性前列腺和乳腺肿瘤中过度表达的 AKR1C3 酶。因此，为了开发针对这些癌症的新细胞毒抑制剂，从绿蜂胶中分离出三种异戊二烯化化合物，青蒿素 C、drupanin 和 baccharin，通过与不同氨基酸的偶联反应合成新的衍生物。所有获得的衍生物都进行了针对四种癌细胞（MCF-7、MDA MB-231、PC-3 和 DU145）和两种正常细胞系（MCF-10A 和 PNT-2）的抗增殖试验，以评估它们的细胞毒性。一般来说，观察到化合物的最佳活性 如图6e所示，衍生自drupanin，其对MCF-7细胞的半数最大抑制浓度(IC 50 )为9.6 ± 3 μM，选择性指数(SI)为5.5。 计算机 研究表明，这些衍生物呈现出针对 AKR1C3 的连贯对接相互作用和结合模式，这可能代表了

  Various practical methods for the selective C−H functionalization of the ortho and recently also of the meta position of an arene have already been developed. Following our recent development of the directing‐group‐assisted para C−H functionalization of toluene derivatives, we herein report the first remote para C−H functionalization of phenol derivatives by using a recyclable silicon‐containing biphenyl‐based
