Abstract:

Novel indolo-macrocycles have been generated from the attempts to synthesise bis-indolo-cyclotriveratrylenes by the condensation of I, I'-diindolyl-3,3'-dimethanols catalysed by p-toluenesulfonic acid. The addition of substituents on indoles led to enhanced solubilities of the macrocycles. Nine- and six-membered ring compounds have been synthesized from the acid-catalysed reaction of I,I'-diindolyl compounds and aryl aldehydes. Some reactions of these compounds and the attempted synthesis of 2,2' diindolylmethanes from the cyclic compounds have also been described. The electrophilic substitu

Abstract:

Degradability of atrazine, cyanazine, and dicamba under methanogenic conditions was evaluated using serum bottle microcosms containing wetland soil inocula obtained from three different sites. Pesticides were monitored by high-performance liquid chromatography (HPLC) and the production of methane was measured with a gas chromatograph (GC). Dicamba was the most susceptible to degradation in the microcosms, followed by cyanazine. Atrazine was not degraded in the wetland soils. A dicamba-degrading methanogenic consortium was enriched from one of the initial wetland soil microcosms (Lawnes). Dicam

Abstract:

For the purpose of incorporating indoles into organometallic complexes for catalysis, as well as in the generation of new heterocyclic systems, various reactions have been carried out at C2, C6 and C7 of the indole system. In order to achieve this, 3-substituted 4,6-dimethoxyindoles and 6-hydroxy- 4-methoxyindoles were necessary as starting materials. Consequently, a lithium-bromide-templated one-pot procedure for the synthesis of some 3-substituted 4,6-dimethoxyindoles and a selective demethylation procedure for 3-substituted 6-hydroxy-4-methoxyindoles were developed. Various kinds of novel

Le greffage de réactifs modèles du NADH a été réalisé sur deux nouveaux supports: un matériau mixte silice-polymère et un polymère acrylique à chiralité intrinsèque. Dans les deux cas, la réduction de substrats classiques a été possible. Avec le second support, une induction asymétrique a été observée. Afin d'effectuer la réduction de substrats non activés en présence d'acides de Lewis capables d'activer de tels substrats, un modèle en série indolo (2,3-)pyridinique a été synthétisé. Il est stable et possède une réactivité élevée. Il est le premier modèle du NADH à avoir permis la réduction qu

Abstract:

An alternate approach to the synthesis of calix[3]indoles has been demonstrated, but further attempted synthetic approaches to calixindoles using new leaving groups led to uncharacterized polymeric products. The synthesis of new 7,7'-diindolylmethane- 2,2'-dicarbaldehydes gives potential for further ligand design and metal complex formation. In addition, 4,6-dimethoxyindole-7- carbaldehydes have been effectively converted to a range of 6-methoxyindole-4,7-diones by Dakin oxidation. Various electrophilic substitution reactions have been performed on the 4,6-dimethoxybenzimidazoles. Formylation

Abstract:

Irradiation of a tryptamine linked through its side-chain nitrogen to an alkylidene malonate residue results in an intramolecular [2 + 2] cycloaddition to the indole 2,3-double bond. The resultant cyclobutane undergoes spontaneous retro-Mannich fission to produce a spiro[indoline-3,3-pyrrolenine] with relative configuration defined by the orientation of substituents in the transient cyclobutane. The novel tandem intramolecular photocycloaddition- retro-Mannich (TIPCARM) sequence leads to a spiropyrrolidine which is poised to undergo a second retro-Mannich fragmentation [TIPCA(RM)₂] that expels

Abstract:

PURPOSE: Cytochrome P450 2W1 (CYP2W1) is a monooxygenase detected in 30% of colon cancers, whereas its expression in nontransformed adult tissues is absent, rendering it a tumor-specific drug target for development of novel colon cancer chemotherapy. Previously, we have identified duocarmycin synthetic derivatives as CYP2W1 substrates. In this study, we investigated whether two of these compounds, ICT2705 and ICT2706, could be activated by CYP2W1 into potent antitumor agents. EXPERIMENTAL DESIGN: The cytotoxic activity of ICT2705 and ICT2706 in vitro was tested in colon cancer cell lines expre
