A new synthetic analogue of the bracken ultimate carcinogen: Elevation of stability and alteration of DNA alkylation site selectivity
摘要:
The benzodienone 4 as a stable analogue of the bracken ultimate carcinogen (2) has been designed and synthesized. In the reaction with DNA the compound 4 was found to give only the N-7 alkylated product of guanine and no N-3 alkylated product of adenine and reveal guanine-selective cleavage in contrast to the natural dienone 2.

Two simple analogues (3 and 4) of a bracken ultimate carcinogen 2 have been synthesized. These compounds, 3 and 4, have been shown to possess the DNAcleavingactivities comparable to that of natural ultimate carcinogen 2.
