Generation of new protein kinase inhibitors utilizing cytochrome p450 mutant enzymes for indigoid synthesis.

Abstract excerpt

Indigoids, a class of bis-indoles, represent a promising protein kinase inhibitor scaffold. Oxidation of indole by cytochrome P450 (P450) has been shown to generate species (indoxyl, isatin) that couple to yield indigo and indirubin. Escherichia coli-expressed human P450 2A6 mutants isolated from a randomized library were incubated with 27 substituted indole derivatives. Extracts of the cultures were screened for...
