Electrooxidation Enables Selective Dehydrogenative [4+2] Annulation between Indole Derivatives

Dearomative annulation of indoles has emerged as a powerful tool for the preparation of polycyclic indoline-based alkaloids. Compared with well-established methods towards five-membered-ring-fused indolines, the six-membered-ring-fused indolines are rarely accessed under thermal conditions. Herein, a dearomative [4+2] annulation between different indoles is developed through an electrochemical pathway. This transformation offers a remarkably regio- and stereoselective route to highly functionalized pyrimido[5,4-b]indoles under oxidant- and metal-free conditions. Notably, this electrochemical approach maintains excellent functional-group tolerance and can be extended as a modification tactic for pharmaceutical research. Preliminary mechanism studies indicate that the electrooxidation annulation proceeds through radical-radical cross-coupling between an indole radical cation and an N-centered radical generated in situ.

Mechanism and enantioselectivity of the asymmetric [3+2]-annulation between N-methylindole and enoldiazoacetamide catalyzed by prolinate-coordinated dirhodium: A theoretical study

The mechanistic study of Rh-2(S-MSP)(4)-catalyzed asymmetric [3 + 2]-annulation of N-methylindole and enoldiazoacetamide carbenoid to produce C2,C3-fused indole skeleton has been carried out by combining the density functional theory and semi-empirical method with ONIOM methodology. The mechanism and origin of enantioselectivity were disclosed by our calculations. The cycloaddition process was initiated by vinylogous attack of indole on the mot terminus of carbenoid, which was considered to be the enantio-controlling step. Followed by ring closure step where C-Rh bond adds to the iminium, adduct was afforded enantioselectively. The rate-controlling step, depending on the pathways the reaction proceeds along, could be either one of the two steps. Moreover, we elucidated the effect of weak interaction on the enantioselectivity using the independent gradient model analysis and provided possible insight into reaction design. The catalytic cycle was also kinetically interpreted in a non conventional way, which is the energetic span model, realized by the AUTOF program. (C) 2019 Elsevier Inc. All rights reserved.

Deciphering interior polarity of lysosome in live cancer and normal cells using spectral scanning microscopy

A lysosome specific, pH tolerant, and polarity-sensitive fluorescent probe (LyPol) is designed and synthesized for the determination of lysosomal polarity in live cells. LyPol possesses an intramolecular charge transfer (ICT) properties with high quantum yield in water and in other polar solvents such as methanol, ethanol, dimethyl sulfoxide, acetonitrile, etc. The fluorescence maxima and lifetime increase linearly with a non-specific manner with an increase in the polarity of its surrounding environment. A morpholine group connected with an alkyl linker acts as a lysosome directing moiety, which is attached to the fluorescent core of LyPol. The selective localization of LyPol inside the lysosome was confirmed with live-cell confocal imaging. Further, the spectral scanning confocal technique was utilized to determine the emission spectrum of LyPol inside lysosome, and the polarity turns out to be quite lower as compared to water. Moreover, the combined spectroscopic and live-cell microscopy confirms that the interior of the lysosome is significantly non-polar in cancer cells compared to normal cells. We believe that this report on the measuring polarity inside the biological system with a solvatofluorochromic probe will be of immense interest to researchers working in the multidisciplinary area of biophysics, microscopy, chemical biology, and organelle biology.

Several molecules have demonstrated a considerable cytotoxicity against A549, HEK293T, MCF7 and VA13 cancer cell lines. The possible mechanism of anticancer activity of the synthesized compounds based on literature data may be the inhibition of p53/MDM2 interaction; however, we did not observe significant p53 activation using a reporter construction in A549 cell line in the relevant concentration range.

In the present study, we describe the in vitro activities and mode of action of 3 ‘ ,4 ‘ -dihydro-2 ‘ H-spiro[indoline-3,1 ‘ -isoquinolin]-2-ones, a novel class of spirofused tetrahydroisoquinoline-oxindole hybrids, as novel antimalarial agents. Whole cell phenotypic screening of these compounds identified (14b), subsequently named (+/-)-moxiquindole, as the most potent compound in the current series with equipotent antiplasmodial activity against both chloroquine sensitive and multidrug resistant parasite strains with good selectivity. The compound was active against all asexual stages of the parasite including inhibition of merozoite egress. Additionally, (+/-)-moxiquindole exhibited significant inhibitory effects on hemoglobin degradation, and disrupted vacuolar lipid dynamics. Taken together, our data confirm the antiplasmodial activity of (+/-)-moxiquindole, and identify 3 ‘ 4 ‘ -dihydro-2 ‘ H-spiro[indoline-3,1 ‘ -isoquinolin]-2-ones as a novel class of antimalarial agents with multiple modes of action.
