Synthesis and properties of peptide nucleic acids containing a psoralen unit

Org Lett. 2001 Mar 22;3(6):925-7. doi: 10.1021/ol015549x.

Abstract

We prepared the psoralen PNA unit from 8-methoxypsoralen and synthesized various PNAs containing psoralen by a typical (t)()Boc method. PNAs containing psoralen (P-PNA) at strand end formed a stable duplex with complementary DNA. The hybridization of P-PNA with complementary DNA resulted in a considerable decrease of the psoralen fluorescence.
