Recently, we have reported that 2-bromopropane might have an immunotoxic potential in rats when exposed for 28 days. In the present studies, the possibility of 2i-deoxyguanosine abduct formation by 2- bromopropane was investigated in vitro to elucidate molecular mechanism of 2-bromopropane-induced immunosuppression. $N^7-Guanine adduct$ of 2'-bromopropane (i.e., $N^7-isopropyl$ guanine) was chemically synthesized and structurally characterized by analysis of UV,$^1H-NMR,{\;}^{13}C-NMR$, COSY and fast atom bombardment mass spectrometry to use as a reference material. Incubation of 2'-deoxyguanosine with an excess amount of 2-bromopropane in PBS buffer solution, pH 7.4, at $37^{\circ}C$ for 16 h, followed by a thermal hydrolysis, produced a detectable amount of $N^7-isopropyl$ guanine by an HPLC and UV analysis. The present results suggest that 2-bromopropane might form a DNA adduct in $N^7-position$ of 2'-deoxyguanosine at 3 Physiological condition.
