Bronsted acid catalyzed alkylation of indoles with tertiary propargylic alcohols: Scope and limitations

Direct alkylation of indoles with a wide variety of tertiary propargylic alcohols under Bronsted acid catalysis conditions has been studied. A general and environmentally friendly method for the synthesis of 3-propargylated indoles with quaternary carbon atoms at their propargylic positions has been developed. The reactions are highly regioselective with regard both to the indole and to the alkynol components. Only with N-unsubstituted 2-arylindoles do competitive SN? reactions take place to afford 3-dienyl- or 3-allenylindoles, depending on the alkynol moiety. The reactions were carried out in air with undried solvents, and water was the only side product. Treatment of indoles with tertiary propargylic alcohols in the presence of Bronsted acid catalysts provided 3-propargylindoles with quaternary centers at their propargylic positions. In addition, 3-dienyl- and 3-allenylindoles could also be obtained with convenient substitution in the indole and alkynol components. The reactions needed no special precautions, and water was the only side product. Copyright

Design and synthesis of novel 2-amino-5-hydroxyindole derivatives that inhibit human 5-lipoxygenase

Compounds that inhibit 5-lipoxygenase (5-LO), the key enzyme in the biosynthesis of leukotrienes (LTs), possess potential for the treatment of inflammatory and allergic diseases as well as of atherosclerosis and cancer. Here we present the design and the synthesis of a series of novel 2-amino-5-hydroxyindoles that potently inhibit isolated human recombinant 5-LO as well as 5-LO in polymorphonuclear leukocytes, exemplified by ethyl 2-[(3-chlorophenyl)amino]-5-hydroxy-1H-indole-3-carboxylate (3n, IC50 value ? 300 nM). Introduction of an aryl/arylethylamino group or 4-arylpiperazin-1-yl residues into position 2 of the 5-hydroxyindoles was essential for biological activity. Whereas the 4-arylpiperazin-1-yl derivatives were more potent in cell-free assays as compared to intact cell test systems, aryl/arylethylamino derivatives inhibited 5-LO activity in intact cells and cell-free assays almost equally well. On the basis of their 5-LO inhibitory properties, these novel 2-amino-5-hydroxyindoles represent potential candidates for the pharmacological intervention with LT-associated diseases.

Synthesis of 3-Amino-5H-pyrido<4,3-b>indoles, Carcinogenic gamma-Carbolines

The carcinogenic gamma-carbolines 3-amino-1,4-dimethyl-5H-pyrido<4,3-b>indole (1) and 3-amino-1-methyl-5H-pyrido<4,3-b>indole (2) were synthesized efficiently by the following procedures.The key method involved the acid-catalyzed cyclization of 2-acetamido-3-(2-indolyl)alkanoic acids to 1,2-dihydro-gamma-carbolines.This was followed by dehydrogenation to the gamma-carbolinecarboxylates and conversion of the ester group to the carboxyl and finally to the amino one by Curtius rearrangement.Alternative methods involved the thermolysis of 4-(1-benzotriazolyl)-3,6-dimethyl-2-pyridinamine to synthesize 1 and the condensation of 3-acetylindole-2-acetonitrile with ammonia to synthesize 2.The structures of gamma-carbolines 1 and 2 were unambiguously established by comparing samples of each synthesized by the two different routes.A selective and one-step synthesis of ethyl 2-acetamido-3-(2-indolyl)alkanoates was newly exploited starting from diethyl acetamidomalonate and quaternary ammonium salts of 2-<1-(dimethylamino)alkyl>indoles.

Polydopamine-coated nanocomposites of Angelica gigas Nakai extract and their therapeutic potential for triple-negative breast cancer cells

Polydopamine (PD)-coated nanocomposites (NCs) based on the ethanol extract of Angelica gigas Nakai (AGN EtOH ext) were fabricated and evaluated for breast cancer therapy. AGN NCs were prepared using a modified emulsification-solvent evaporation method and were further incubated in dopamine solution (at pH 8.6) to be covered with the PD layer. PD-AGN NCs with a 213-nm mean diameter, narrow size distribution, and negative zeta potential values were fabricated in this study. Less negative (close to zero) zeta potential value of PD-AGN NCs than that of AGN NCs implied the existence of the PD layer in the outer surface of NCs. The PD layer in PD-AGN NCs was also identified by X-ray photoelectron spectroscopy (XPS) and ultraviolet (UV)/visible absorption analyses. The sustained release of decursin (D) and decursinol angelate (DA), as major active pharmacological components of AGN, was observed in both AGN NCs and PD-AGN NCs. Enhanced cellular binding property of PD-AGN NCs, compared to AGN NCs, in MDA-MB-231 (human breast adenocarcinoma; triple-negative breast cancer) cells was observed. Improved anticancer activities of PD-AGN NCs compared with those of AGN EtOH ext and AGN NCs were also shown in MDA-MB-231 cells. The developed PD-AGN NCs may be used as remarkable platform nanocarriers for efficient breast cancer therapy.

A magnetic metal-organic framework as a highly active heterogeneous catalyst for one-pot synthesis of 2-substituted alkyl and aryl(indolyl)kojic acid derivatives

A novel magnetic metal-organic framework, NiFe2O4@MOF-5, has been prepared and characterized using spectroscopic, microscopic, and magnetic techniques (FT-IR, XRD, TEM, SEM, EDX, and VSM). This magnetically separable catalyst exhibited high catalytic activity for the synthesis of a variety of 2-substituted alkyl and aryl(indolyl)kojic acid derivatives via a one-pot, three-component reaction of aldehyde, indole, and kojic acid under solvent-free conditions. The catalyst can be easily magnetically separated and exhibits significant recyclability, with no significant loss of activity after six consecutive runs.
