Synthesis of [5-(4-pyrrol-1-yl-benzoyl)-1 H-pyrrol-2-yl)]-acetic acid and in vitro study of its inhibitory activity on aldose reductase enzyme and on protein glycation.

[5-(4-Pyrrol-1-yl-benzoyl)-1H-pyrrol-2-yl)]-acetic acid was synthesized in a Vilsmeier-Haack process and by other methods. The compound was found to inhibit the enzyme aldose reductase as well as the glycation process of proteins and could therefore be useful for the treatment of various pathological conditions.
