New synthetic routes to furocoumarins and their analogs: a review

Many furocoumarins and their analogs possess a prominent photobiological activity. Some of them are successfully used as drugs in phototherapy of skin diseases. Fries rearrangement of acyloxyheteroarenes, condensation of acylhydroxyheteroarenes with alpha-carbonyl compounds under base catalysis and transformations of dihydrofurocoumarinones are new trends in synthesis of furocoumarins and their analogs.

Synthesis and properties of peptide nucleic acids containing a psoralen unit

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.
