Discovery of the cancer cell selective dual acting anti-cancer agent (Z)-2-(1H-indol-3-yl)-3-(isoquinolin-5-yl)acrylonitrile (A131)

Selective targeting of cancer cells over normal cells is a key objective of targeted therapy. However few approaches achieve true mechanistic selectivity resulting in debilitating side effects and dose limitation. In this work we describe the discovery of A131 (4a), a new agent with an unprecedented dual mechanism of action targeting both mitosis and autophagy. Compound 4a was first identified in a phenotypic screen in which HeLa cells treated with 4a manifested mitotic arrest along with formation of multiple vesicles. Further investigations showed that 4a causes an increase in mitotic marker pH3 and autophagy marker LC3. Importantly 4a induces cell death in cancer cells while sparing normal cells which regrow after 4a is removed. Dual activities against pH3 and LC3 markers are required for cancer cell selectivity. An extensive SAR investigation confirmed 4a as the optimal dual inhibitor with potency against a panel of 30 cancer cell lines (average antiproliferative GI50 1.5 muM). In a mouse model of paclitaxel-resistant colon cancer, 4a showed 74% tumor growth inhibition when administered at a dose of 20 mg/kg IP twice a day.

Organocatalytic asymmetric Michael addition of aliphatic aldehydes to indolylnitroalkenes: Access to contiguous stereogenic tryptamine precursors

Because of the importance of the indole framework and the versatile transformation of nitro and formyl groups, the efficient synthesis of optically pure 2-alkyl-3-(1H-indol-3-yl)-4-nitrobutanals, one type of tryptamine precursors are of great interest for pharmaceutical and biological research. Herein, the Michael addition of aliphatic aldehydes to indolylnitroalkenes has been developed using (S)-diphenylprolinol trimethylsilyl ether as an organocatalyst, which provides the desired optically pure syn 2-alkyl-3-(1H-indol-3-yl)-4-nitrobutanal derivatives in up to 98% yield with up to >99:1 dr and >99% ee. To show the synthetic usefulness of this methodology, optically active 2-alkyl-4-nitro-3-(1-tosyl-1H-indol-3-yl)butan-1- ol and tryptamine derivatives are readily obtained by stepwise systematic transformations.

MIL-101-SO3H metal-organic framework as a Br¡ãnsted acid catalyst in Hantzsch reaction: An efficient and sustainable methodology for one-pot synthesis of 1,4-dihydropyridine

A straightforward and efficient methodology for the one-pot multicomponent synthesis of 1,4-dihydropyridine has been developed using MIL-101-SO3H metal-organic framework as a solid Br¡ãnsted acid. The presence of the uniformly distributed Br¡ãnsted acidic sulfonic acid sites throughout the framework and the high stability bestow the catalyst with excellent reactivity towards the synthesis of 1,4-dihydropyridine under simple reaction conditions using renewable ethanol as the solvent. The present methodology tolerates various functional groups and allows the synthesis of 1,4-dihydropyridine derivatives in good to excellent yields through Hantzsch reaction. The developed methodology proceeds under mild conditions, avoids corrosive reagents and special reaction conditions, and is amenable to gram scale synthesis. The sustainable nature of the catalyst was proved by the easy recovery and the reusability of the catalyst, as it was reused several times without loss in activity, which was confirmed from the FTIR, PXRD and SEM analyses of the reused catalyst.

Suppression of fluconazole resistant Candida albicans biofilm formation and filamentation by methylindole derivatives

Candida albicans is an opportunistic fungal pathogen and most prevalent species among clinical outbreaks. It causes a range of infections, including from mild mucosal infections to serious life-threatening candidemia and disseminated candidiasis. Multiple virulence factors account for the pathogenic nature of C. albicans, and its morphological transition from budding yeast to hyphal form and subsequent biofilm formation is regarded as the most important reason for the severity of Candida infections. To address the demanding need for novel antifungals, we investigated the anti-biofilm activities of various methylindoles against C. albicans using a crystal violet assay, and the metabolic activity was assessed by using a 2,3-bis (2-methoxy-4-nitro-5-sulfo-phenyl)-2H-tetrazolium-5-carboxanilide reduction assay. Changes in biofilm morphologies and thicknesses were determined by confocal laser scanning microscopy and scanning electron microscopy, respectively. Of the 21 methylindoles tested, 1-methylindole-2-carboxylic acid (1MI2CA) at 0.1 mM (17.5 mug ml-1) and 5-methylindole-2-carboxylic acid (5MI2CA) at 0.1 mM effectively inhibited biofilm formation by C. albicans DAY185 and ATCC10231 strains. Moreover, 1MI2CA and 5MI2CA both effectively inhibited hyphal formation, and thus, improved C. albicans infected nematode survival without inducing acute toxic effects. Furthermore, our in silico molecular modeling findings were in-line with in vitro observations. This study provides information useful for the development of novel strategies targeting candidiasis and biofilm-related infections.

Diversity oriented synthesis of a vinblastine-templated library of 7-aryl-octahydroazonino[5,4-b]indoles via a three-component reaction

A vinblastine-templated library of 7-aryl-octahydroazonino[5,4-b]indoles was prepared by a three-component reaction from indolizino[8,7-b]indoles, chloroformates, and activated arenes via a chloroformate mediated fragmentation of the indolizinoindole nucleus followed by insertion of an activated arene. In addition to N3-carbamoyl-7-aryl-octahydroazonino[5,4-b]indoles prepared in one step, a wide range of N3-substituted substrates were synthesized in one pot via the derivatization of a versatile N3-H-azonino[5,4-b]indole intermediate generated in situ by application of the same strategy. A subset of 308 compounds out of a virtual library of 3216, representing 13 different chemotypes, was prepared by high throughput solution-phase synthesis and subsequently purified by mass-triggered high performance liquid chromatography (HPLC). A total of 188 compounds with a minimum purity of 80% by UV214 nm and 85% by evaporative light scattering detection (ELSD) was isolated for primary screening.

Synthesis of annulated bis-indoles through Au(i)/Br¡ãnsted acid-catalyzed reactions of (1H-indol-3-yl)(aryl)methanols with 2-(arylethynyl)-1H-indoles

A general method to access annulated bis-indoles from (1H-indol-3-yl)(aryl)methanols and 2-(arylethynyl)-1H-indoles under the catalysis of the Ph3PAuOTf/Br¡ãnsted acid binary catalyst system has been developed. The reaction was found to proceed in a highly efficient manner and benefit from easy-to-make starting materials, broad substrate scope and operational simplicity. The potential of this method has also been exemplified for the synthesis of pyrrole-annulated indoles using 2-(phenylethynyl)-1H-indoles and phenyl(1H-pyrrol-2-yl)methanols. Furthermore, the use of a ternary catalyst system, involving PdCl2/Br¡ãnsted acid/Ph3PAuOTf catalysts, has been realized for the synthesis of annulated bis-indoles starting directly from 2-(phenylbuta-1,3-diyn-1-yl)aniline and (1H-indol-3-yl)(aryl)methanol. Mechanistically, this reaction is very interesting since the overall process involves three different catalytic cycles catalyzed by three different catalysts in a relay fashion.

Spectroscopy of tryptophan derivatives in supersonic expansions: Addition of solvent molecules

The addition of solvent molecules, primarily water and some alcohols, to isolated tryptophan derivative molecules has been carried out using supersonic free jet techniques.The derivatives studied include 3-indole acetic acid, 3-indole propionic acid, N-acetyltryptophan ethyl ester, tryptamine, and tryptophol.The primary spectroscopic method employed was laser induced fluorescence, with some individual bands also characterized by fluorescence lifetime measurements or dispersed emission spectra.Unlike solvent addition to indoles already studied, these tryptophan derivatives also offer polar addition sites on the 3-indole chain.Addition to these sites, further removed from the electronic transition, produces solvent shifts of the complex origins that are small compared to the red shifts observed in indoles; small blue shifts occur in some instances.Competition between binding at the 3-indole polar group and the indole moiety nitrogen sites is strongly unequal, with the polar 3-indole chain sites favored, especially for larger solvent molecules.In tryptamine, which was studied most extensively, a variety of -OH-bearing solvents were able to collapse the multiple origin bands, due to different conformers, to only one prominent solvent conformer feature.Similar though less pronounced effects were seen in trytophol.Growth of solvent bands was more indiscriminate for the other derivatives studied and was consistent with formation of complexes separately with each bare molecule conformer.The observation of a solvent induced conformation brings up the question of whether tryptophan itself may be “steered” predominantly to one conformation by solution interactions and, if so, whether this plays a role in the molecule’s fluorescence probe properties.
