Multisubstituted indole–acrylonitrile hybrids as potential cytotoxic agents
摘要:
A series of multisubstituted indole-acrylonitrile hybrids were designed, synthesized and evaluated for their potential cytotoxic activities. The bio-evaluation results indicated that some of the target compounds (such as 3a, 3f, 3k, 3n) exhibited good to moderate cytotoxic effect on HepG2, BCG-823, BEL7402, and HL-7702 cell lines. Especially, the compounds 3a and 3k also exhibited high cytotoxic activities (3a, 19.38 +/- 3.38 mu M; 3k, 15.43 +/- 3.54 mu M) against the BEL-7402 cell line resistant to Taxol (>25 mu M) and 5-FU (>500 mu M), which might be developed as novel lead scaffold for potential anticancer agents.

6-methoxy-4-aryl-2,2′-bipyridine-5-carbonitrile derivatives has been achieved throughone-potmulti-componentreaction under reflux condition. Particularly valuable features of this method include high yields of products in short reaction time and broad substrate scope. It is an efficient and promising synthetic strategy to build indol-3-ylpyridine and 2,2′-bipyridine skeletons.

A series of dispiropyrrolidine bisoxindoles were synthesized via a multicomponent 1,3-dipolarcycloadditionreaction of isatin, sarcosine and isatylidene malononitrile in refluxing methanol. Also a series of spiropyrrolidine oxindoles and spiroindane-1,3-diones were synthesized using 2-(1H-Indole-3-carbonyl)-3-phenyl-acrylonitrile and 2-(1,3-dioxo-indan-2-ylidene)-malononitrile as dipolarophiles, respectively
A simple and convenient method for the one-pot three-component synthesis of 3-pyranyl indoles has been accomplished by tandem Knoevenagel–Michael reaction of 3-cyanoacetyl indole, various aromatic aldehydes and malononitrile catalyzed by InCl3 in ethanol under reflux conditions. The newly synthesized 3-pyranyl indoles were evaluated for anti-microbial, antioxidant, and anticancer activities. Some of
New 4-(1H-indol-3-yl)-6-arylpyrazolo[3,4-b]pyridines 7 have been prepared in a solvent-free three-component reaction induced by microwave from 5-aminopyrazole 1, benzaldehydes 2 and 3-indolyl-3-oxopropanenitrile 5. These compounds were also obtained by means of the reaction of aminopyrazole 1 with benzylidene-derivatives of 3-(1H-indol- 3-yl)-3-oxopropanenitrile 6, prepared in the reaction of 3-(1H-indol-3-yl)-3-oxopropanenitrile and aldehydes.
An efficient approach for stereoselective synthesis of cyclopropyl indolyl ketone from olefin and arsonium ylied was achieved. Its advantages are of mild condition, high yield, and good stereoselectivity. In addition, the one‐pot cycloproparation of olefins with bromides and triphenylarsine was studied. J.
