A new class of insulin receptor activator with a hydroxyfuroic acid in place of a hydroxyquinone moiety is reported. The synthesis of 3-(1H-indol-3-yl)-5-(1H-indole-3-carbonyl)-4-hydroxyfuroic acids (26-30) requires seven major steps. Key elements in the syntheses include (1) sequential preparation of two 4-(N-protected indole)-3-methoxy-furoic 2,5-dicarboxylic esters (4 and 6); (2) regioselective conversion of the furoic diacid 8 into its C-5 methyl ester 10 with methyl chloroformate; and (3) acylation of 10 by a 7-substituted indole under a mild condition. This study demonstrates a feasible route of synthesizing insulin receptor activators with a hydroxyfuroic acid scaffold. Among those hydroxyfuroic acid compounds, compound 28 demonstrates insulin receptor activation potential comparable to Merck's compound 2 with a dihydroxybenzoquinone scaffold.

A series of novel bisindolylmaleimide and natural amino acid ester conjugates were synthesized and evaluated for their inhibitory activity against six tumor cell lines. Some compounds displayed interesting cytotoxic profiles. The most active compound 8e s
Synthesis of arcyriarubin a and arcyriaflavin a via cross-coupling of indolylboronic acid with dibromomaleimides

experimental part, p. 144 - 150 (2010/03/24)
Arcyriarubin A was first isolated by Steglich in 1980; it is also the key intermediate in the synthesis of indolocarbazole compounds. A new synthetic approach to the natural products arcyriaflavin A and arcyriarubin A is described. The key step is a Suzuk
Synthesis of novel analogues of marine indole alkaloids: Mono(indolyl)-4-trifluoromethylpyridines and bis(indolyl)-4-trifluoromethylpyridines as potential anticancer agents
