Aphids produce novel pigments which are expected to possess interesting biological activities. Therefore, we started chemical investigations of the pigments found in the aphid Uroleucon nigrotuberculatum O. and Aphis spiraecola Patch. Two red pigments and two yellow pigments were isolated from Uroleucon nigrotuberculatum O. feeding on Solidaga altissima L. The red pigments were identified as rhododactynaphins-jc-1 and -jc-2 whose structures were proposed by Cameron. By our detailed investigation, however, the structures of them should be revised to 2a and 2b. Furthermore, the absolute configuration and the stereochemistry of them were established by a single crystal X-ray analysis of (S)-(+)-1-(1-naphtyl)ethyl carbamate 3 of 2b. The structures of two yellow pigments were also elucidated by NMR study. One of them was identified as xantodactynaphin-jc-2, whose structure was also revised to 5 in this study. Another pigment, named xantouroleuconaphin (7), was a dimmer of 6-hydroxymusizin (6) which was isolated from the aphid Aphis nerii. A novel naphtho[2,3-c]furan-4(1H)-one derivative, a yellow pigments named furanaphin (8), was isolated from the aphid A. spiraecola Patch. The structure of 8 was established by a single crystal X-ray analysis of its (S)-MTPA ester. Furanaphin was found to have cytotoxicity against HL-60 human tumor cells.
