1-Toluene-sulfonyl-3-[(3′-hydroxy-5′-substituted)-γ-butyrolactone]-indoles: Synthesis, COX-2 inhibition and anti-cancer activities
摘要:
Indoles carrying a cyclic ester (gamma-butyrolactone) at C-3 position have been synthesized by the allylation of 3-indoleglyoxylate followed by iodocyclisation and the nucleophilic replacement of the iodo-group. Screening of these molecules for COX-2 inhibition and anti-cancer activities has identified compounds 10 and 11 as highly potent and selective for COX-2 as well as showing remarkable anti-cancer activities (better than that of indometbacin).

The influence of experimental conditions and of a wide range of electron-withdrawing indole substituents has been studied in the thermally activated and Lewis acid activated intermolecular Diels-Alder cycloaddition of electron-poor indoles to 2,3-dimethyl-1,3-butadiene.
