9(10H)-ones and N-benzoylated acridones were synthesized on the basis of a retrosynthetic approach. All newly synthesized compounds were tested for antiproliferativeactivity and interaction with tubulin. Several analogs potently inhibited tumor cell growth. Among the compounds tested, 10-(4-(3-methoxyphenyl)piperazine-1-carbonyl)acridin-9(10H)-one (17c) exhibited excellent growth inhibitory effects
作为我们继续寻找微管蛋白聚合的有效抑制剂的一部分,基于 42 10-(4-苯基哌嗪-1-羰基)吖啶-9(10 H )-酮和N-苯甲酰化吖啶酮的两个新系列被合成逆合成方法。测试所有新合成的化合物的抗增殖活性和与微管蛋白的相互作用。几种类似物有效抑制肿瘤细胞生长。在测试的化合物中,10-(4-(3-甲氧基苯基)哌嗪-1-羰基)吖啶-9(10 H)-one ( 17c ) 对 93 种肿瘤细胞系表现出优异的生长抑制作用,平均 GI 50值 5.4 nM。我们能够证明强烈的细胞毒性作用是由微管蛋白聚合的破坏引起的,这得到了 EBI ( N , N'-亚乙基双(碘乙酰胺))测定以及癌细胞生长最有效的抑制剂被证明是最有效的微管蛋白聚合抑制剂这一事实。效力几乎可比或优于抗有丝分裂参考化合物的效力。与此密切相关的是,最活跃的类似物以低至 30 nM 的浓度抑制 G2/M 期的细胞循环并诱导 K562 白血

We have unfolded a convenient and mild protocol for the synthesis of diaryl ketones via Pd‐ NHC catalysed carbonylative Suzuki coupling reaction. Notably, this method offers advantages like no use of toxic CO gas, shorter reaction time, high yield, and broad substrate scope. Several sensitive functional groups (like‐COMe, ‐COOMe, ‐F, ‐Cl, ‐Br, ‐NH2, ‐CN) are well tolerated in this reaction. In addition
tetraalkylthiuram disulfides in the presence of iodine and copper(II) triflate. This reaction directly employs readily available and low-cost thiuram as both a C1 synthon and a nitrogen source, providing a facile approach to one-step syntheses of a variety of 2-aminoquinolines in good to excellent yields.
喹啉,尤其是 2-氨基喹啉,是药物化学中非常重要的杂环化合物。2-氨基喹啉可以通过逐步构建喹啉环,然后进行额外的胺化来合成;然而,这个协议很麻烦。在这里,我们描述了在碘和三氟甲磺酸铜 (II) 存在下 2-乙烯基苯胺与四烷基秋兰姆二硫化物的 [5+1]-环化反应。该反应直接使用容易获得且成本低廉的秋兰姆作为 C1 合成子和氮源,为一步合成各种 2-氨基喹啉提供了一种简便的方法,并且收率良好。
