  2-Aryl-3H-indol-3-ones: Synthesis, electrochemical behaviour and antiplasmodial activities

  摘要：

  The synthesis of indolone derivatives and their antiplasmodial activity in vitro against Plasmodium falciparum at the blood stage are described. The 2-aryl-3H-indol-3-ones were synthesized via deoxygenation of indolone-N-oxides. Electrochemical behaviour, antiplasmodial activity and cytotoxicity on human tumor cell lines were compared to those of indolone-N-oxides. The antiplasmodial IC50 (concentrations at 50% inhibition) of these compounds ranged between 49 and 1327 nM. Among them, the 2(4-dimethylaminophenyl)-5-methoxy-indol-3-one, 7, had the best antiplasmodial activity in vitro (IC50 = 49 nM; FcB1 strain) and selectivity index (SI (CC50 MCF7/IC50 FcB1) = 423.4). Thus, the hits identified in this deoxygenated series correspond to their structural homologs in the N-oxide series with comparable electrochemical behaviour at the nitrogen-carbon double bond.

  We have developed a new strategy for preparing 2-substituted indolone N-oxides (isatogens) by substitution reactions with aryl- and alkyl-organometallic reagents. This approach allows a range of substituents to be incorporated at a late stage and complements existing methods that necessitate their early stage incorporation during substrate preparation. Further chemistry has been found to take place

  我们开发了一种通过与芳基和烷基有机金属试剂进行取代反应来制备 2-取代吲哚酮 N-氧化物（isatogens）的新策略。这种方法允许在后期阶段引入一系列取代基，并补充了在底物制备过程中需要早期引入的现有方法。已经发现在硝酮部分发生了进一步的化学反应；分子内偶极环加成提供了获得有角度稠合的三环杂环的途径。然而，更不寻常的是，这些化合物易于通过有机锌试剂进一步加成，从而产生 2,2-二取代的 3-羟吲哚产物。

  A series of 66 new indolone-N-oxide derivatives was synthesized with three different methods. Compounds were evaluated for in vitro activity against CQ-sensitive (3D7), CQ-resistant (FcB1), and CQ and pyrimethamine cross-resistant (K1) strains of Plasmodium falciparum (P.f.), its well as for cytotoxic concentration (CC50) on MCF7 and KB human tumor Cell lines. Compound 26 (5-methoxy-indolone-N-oxide analogue) had the most potent antiplasmodial activity in vitro (< 3 nM on FcB1 and = 1.7 nM on 3D7) with a very satisfactory selectivity index (CC50 MCF7/IC50 FcB1: 14623; CC50 KB/IC50 3D7: 198823). In in vivo experiments, compound 1 (dioxymethylene derivatives of the indolone-N-oxide) showed the best antiplasmodial activity against Plasmodium berghei, 62% inhibition of the parasitaemia at 30 mg/kg/day.

  A Cu-promoted cyclization of 2-nitrophenyl iodoacetylenes provides a direct route to a range of 2-iodoisatogens. These compounds represent useful intermediates for the late-stage elaboration of the C-I bond to furnish isatins and a range of alternative heterocyclic products.
