Chlorophyll Catabolite

“Non-fluorescent” chlorophyll catabolites (NCCs) were named “rusty pigments” originally, as they easily oxidized to yellow chlorophyll catabolites (YCCs) and other colored natural “phyllobilins.” In the present work, binding of Zn(II)-ions by YCC and its methyl ester YCC-Me, and structural investigations of the resulting Zn(II)-complexes are reported. Binding of Zn-ions to the weakly luminescent YCC or YCC-Me in DMSO produces orange-yellow complexes that exhibit strong green emission. The Zn-complex of YCC-Me was isolated and characterized by UV-vis-, fluorescence-, mass- and NMR-spectra. The data revealed a 2:1 complex, Zn(YCC-Me)[Formula: see text], in which YCC-Me serves as bidentate ligand. The Zn(II)-center in Zn(YCC-Me)[Formula: see text] is, thereby, deduced to be coordinated in a pseudo tetrahedral fashion. Formation of Zn(YCC-Me)[Formula: see text] (and of Zn(YCC)[Formula: see text] is compatible with an isomerization of the lactam form of ring D to the corresponding lactim tautomer in these neutral Zn(II)-complexes.

Herbivorous insects excrete most of the consumed chlorophyll as partly degraded derivatives lacking the phytol side chain and the central magnesium ion. To study common degradation patterns of chlorophyll in plant-feeding insects, the frass of the Lepidopteran caterpillar, Aglais urticae was analysed for chlorophyll catabolites. The major metabolites were determined as pheohorbide a and pyropheophorbide a by using LC-MS, LC-SPE-NMR and UV. These compounds are not present in fresh leaves of the food plants (Urtica dioica).
