The opine known as cucumopine 1 produced by crown gall tumours and hairyroot exhibited chemical and spectroscopic data corresponding to 4-(2-carboxyethy1)-4,5,6,7-tetrahydroimidazo[4,5-c]pyridine-4,6-dicarboxylic acid. The identification was verified by a biogenetic type synthesis from L-histidine and α-ketoglutaric acid.
