Syntheses and cytotoxicity evaluation of bis(indolyl)thiazole, bis(indolyl)pyrazinone and bis(indolyl)pyrazine: analogues of cytotoxic marine bis(indole) alkaloid
摘要:
2,4-Bis(3'-indolyl)thiazoles, 3,5-bis(3'-indolyl)-2(1H)pyrazinone and 3,6-bis(3'-indolyl)pyrazine were synthesized and evaluated for cytotoxic activity against diverse human cancer cell lines by the National Cancer Institute. These compounds demonstrated significant inhibitory effects in the growth of a range of cancer cell lines. 2,4-Bis(3'-indolyl)thiazole displayed selective cytotoxicity against certain leukemia cell lines with GI(50) values in the low micromolar range while the substituted derivatives showed a broad spectrum of cytotoxic activity. 3,5-Bis(3'-indolyl)-2(1H)pyrazinone and 3,6-bis[3'-(N-methyl-indolyl)]pyrazine possessed strong inhibitory activity against a wide range of human tumor cell lines. The mechanism of action remained unknown. The results suggested that 2,4-bis(3'-indolyl)thiazoles, 3,5-bis(3'-indolyl)-2(1H)pyrazinone and 3,6-bis[3'-(N-methyl-indolyl)] pyrazine offer potential as lead compounds for the discovery of anticancer agents.

The Masuda borylation/Suzuki arylation (MBSA) sequence starting from N-protected 3-iodoindoles has successfully been extended to the coupling of five-membered heterocycles and indoles in the arylation step, which could not be achieved with previously developed MBSA methods. By this approach the one-pot nature of the method as well as the use of a simple catalyst system has been retained. The applicability

The thiazole analogues of the marine bis(indole)alkaloid nortopsentins, 2,4-bis(3-indolyl)thiazoles, were synthesized using Hantzsch reaction between indole-3-thioamides and 3-(alpha-bromoacetyl)indoles as the key step, and these analogues showed potent cytotoxic activities against a variety of human cancer cell lines in vitro.

Optimization, Structure–Activity Relationship, and Mode of Action of Nortopsentin Analogues Containing Thiazole and Oxazole Moieties
Plant diseases seriously endanger plant health, and it is very difficult to control them. A series of nortopsentin analogues were designed, synthesized, and evaluated for their antiviral activities and fungicidal activities. Most of these compounds displayed higher antiviral activities than ribavirin. Compounds 1d, 1e, and 12a, with excellent antiviral activities, emerged as novel antiviral lead compounds
