The dibenzofuran- and carbazole-substituted oximes or methyloximes 5–10 were prepared and evaluated for their cytotoxic and antiplatelet activities. These compounds were synthesized via alkylation of dibenzofuran-2-ol or 9H-carbazol-2-ol with α-halocarbonyl reagents, followed by reaction with NH2OH or NH2OMe (Scheme). A preliminary anticancer assay indicated that the oxime-type dibenzofuran derivatives
的dibenzofuran-和咔唑基取代的肟或methyloximes 5 - 10制备并评价它们的细胞毒性和抗血小板活性。这些化合物的合成方法是,将二苯并呋喃-2-醇或9 H-咔唑-2-醇与α-卤代羰基试剂进行烷基化,然后与NH 2 OH或NH 2 OMe反应(方案)。初步的抗癌分析表明,肟型二苯并呋喃衍生物5和7a – d具有活性,而相应的肟醚9b和9c在相同浓度下不活跃。因此,一个供氢键的基团似乎对细胞毒性至关重要。在测试的化合物中,2-[((二苯并[ b,d ]呋喃-2-基)氧基] -1-(4-甲氧基苯基)乙-1-酮-O-甲基肟(9c)对诱导的血小板凝集表现出有效的抑制活性。花生四烯酸的IC 50值为14.87μM,浓度为100μM时无细胞毒性。
