抄録

A novel isoprenoid derivative N-solanesyl-N, N'-bis(3, 4-dimethoxybenzyl) ethanediamine (SDB), weak fluorescence compound having secondary amino group in the molecule, is an anti-tumor activity potentiating agent for a variety of anti-tumor agents, e.g., adriamycin, 5-fluorouracil and mitomycin C. A precolumn fluorescence labeling reagent was investigated for a highly sensitive detection method of SDB by HPLC. SDB was converted into its urea derivatives using three kinds of activated carbamate reagents synthesized from N, N'-disuccinimidyl carbonate by reacting with α-naphthylamine (α-NA), 2-aminoanthracene (2-AT) or 2-aminofluorene (2-AF) as a fluorescence molecule group. The fluorescence intensities of naphthylcarbamyl and anthrylcarbamyl derivatives of SDB converted by using α-NA and 2-AT were ca. 3-fold and 13-fold compared to that of SDB, respectively. On the other hand, the fluorescence intensity of fluorenylcarbamyl deriva tive of SDB obtained in the reaction with succinimido-2-fluorenylcarbamate (SFC) synthesized by using 2-AF was ca. 45-fold greater than that of SDB. The reaction time was within 5min at room temperature: the reaction mixture could be analyzed directly by means of reversed-phase HPLC using fluorometric detection at 343nm while excited at 286 nm for emission wavelengths. The detection limit was 20pg (S/N=2). SFC facilitated the simple and rapid precolumn derivatization of SDB for the highly sensitive fluorometric detection.
