Difference of DNA Compaction Performed by Two kinds of Oncopterin-Mimic Pteridine - Polyamine Conjugates

Two types of pteridine - polyamine conjugates designed on oncopterin perform different actions to DNA. The most obvious difference is their actions in DNA compaction. One of the pteridine - polyamine conjugates, PT- 2R, containing a polyamine substituent (R) on the C(2) position of pterin (PT) compa...

Description
Summary:Two types of pteridine - polyamine conjugates designed on oncopterin perform different actions to DNA. The most obvious difference is their actions in DNA compaction. One of the pteridine - polyamine conjugates, PT- 2R, containing a polyamine substituent (R) on the C(2) position of pterin (PT) compacts a DNA molcculc in an all-or-none fashion without the intervention of an intermediate. The othcr (PT-4R: R exists on the c(4) position of PT) carries out the DNA compaction via partially compacted intermediates. The difference is discussed based on various interaction modes of the pteridine - polyamine conjugates to DNA.
