Secondary metabolites of slime molds (myxomycetes)

“…13) (Steglich et al, 1980). The indole[2,3-a]carbazole alkaloid ring system is present in several biologically active molecules, such as the arcyriaflavins and related compounds (Steglich, 1989).…”

Sensitization of Nanocrystalline TiO2 Films with Carboxy‐Functionalized Bis(indolyl)maleimide

“…For this purpose, N-methylbis(indolyl)maleimide 1 was chosen as the starting compound for the synthesis and prepared according to a procedure published by Steglich et al [18] 3,4-Bis[1-(carboxymethyl)-3-indolyl]-1H-pyrrole-2,5-dione (BIM-COOH) was prepared according to an adapted procedure described by Xie et al [19] (see Scheme 2) Methyl Scheme 2. Schematic procedure for the synthesis of BIM-COOH.…”

Protecting-group-free synthesis of the bisindolylmaleimide GF109203X

“…5 More importantly, a fruitful strategy has been developed to design more selective inhibitors by disrupting the planarity of the indolocarbazole ring system. Among them, bisindolylmaleimides (BIMs) 6,7 derived from arcyriarubin A (3) 8,9 are successful examples, which are of interest because of their PKC inhibitory activity. Mono-N'-substituted BIMs such as compounds 4-6 ( Figure 1: for simplicity, the nitrogen in the maleimide ring is referred to as N, the other two nitrogens in indole rings are marked as N' and N'' respectively) represent a class of excellent PKC inhibitors.…”
