Abstract
This invention discloses a molecule bearing a biologically active group (a phenanthridinium moiety) joined covalently to an oligonucleotide recognition system (a phosphorus nucleoside group) by a linker that permits intercalation of the active group in the pocket formed by the nucleotide and complementary bases in another polynucleotide strand. This class of compounds is illustrated by the following: ##STR1## where R is selected from the group consisting of --NH2, methylamino, or ethylamino or hydrogen;
where R'"'"' is selected from the group consisting of --NH2, methylamino, or ethylamino or hydrogen;
where the chain linking the linker group to the phenanthridinium group (R") consists of 2-8 --CH2 -- groups.
