| Abstract [eng] |
A method for the synthesis of asymmetric carboxy-substituted indirubins is presented. It employs indole-5-carboxylic acid or indole-6-carboxylic acid and 2-indolinone derivatives as substrates for bacterial monooxygenase-driven enzymatic bioconversion in different bacterial hosts. This bioconversion system achieved the highest titer of monocarboxyindirubin production of up to 327 mg L−1 for 5-bromoindirubin-6′-carboxylic acid during the 16-h incubation period. The purified monocarboxyindirubins exhibited high solubility in water, up to three orders of magnitude higher than that of indirubin. In addition, several monocarboxyindirubins, namely 1-methylindirubin-5′-carboxylic acid, possess potent antiproliferative activity against different cancer cell lines. Therefore, the synthesis method for monocarboxyindirubins described herein is an efficient and environmentally friendly bioconversion system and the synthesized monocarboxyindirubins show great promise due to their high water solubility and potential antiproliferative activity. |
