  Synthesis and Antiplasmodial Activity of New Indolone N-Oxide Derivatives

  摘要：

  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.

  Styrylphenylphthalimides as Novel Transrepression-Selective Liver X Receptor (LXR) Modulators

  摘要：

  Anti-inflammatory effects of liver X receptor (LXR) ligands are thought to be largely due to LXR-mediated transrepression, whereas side effects are caused by activation of LXR-responsive gene expression (transactivation). Therefore, selective LXR modulators that preferentially exhibit transrepression activity should exhibit anti-inflammatory properties with fewer side effects. Here, we synthesized a series of styrylphenylphthalirnide analogues and evaluated their structure activity relationships focusing on LXRs-transactivating-agonistic/antagonistic activities and transrepressional activity. Among the compounds examined, 171 showed potent LXR-transrepressional activity with high selectivity over transactivating activity and did not show characteristic side effects of LXR-transactivating agonists in cells. This representative compound, 171, was confirmed to have LXR-dependent transrepressional activity and to bind directly to LXR beta. Compound 171 should be useful not only as a chemical tool for studying the biological functions of LXRs transrepression but also as a candidate for a safer agent to treat inflammatory diseases.

  Using a single half-sandwich iron(II) compound, Cp*Fe(1,2-Ph2PC6H4S)(NCMe) (Cp*– = C5Me5–, 1) as a catalyst, reductive coupling of nitroarenes with olefins has been achieved by a well-defined iron(II)/(EtO)3SiH system. Through either inter- or intramolecular reductive coupling, various branched amines and indole derivatives have been directly synthesized in one-pot. Mechanistic studies showed that

  使用单一的半夹心铁（II）化合物作为催化剂，将Cp * Fe（1,2-Ph 2 PC 6 H 4 S）（NCMe）（Cp * – = C 5 Me 5 –，1）作为催化剂，进行还原偶联明确定义的铁（II）/（EtO）3 SiH体系可实现硝基芳烃与烯烃的合成。通过分子间或分子内的还原偶联，已经在一锅中直接合成了各种支链胺和吲哚衍生物。机理研究表明，催化作用是由铁（II）催化剂与硅烷活化硝基芳烃而引发的，从而生成用于C-N键偶联的铁-亚硝基芳烃中间体。
