Abstract
Bispsoralen derivatives possessing two psoralens and one piperazine molecule, 1,4-bis[n'-(8-psoralenoxy) alkyl] piperazine (Bis[PsCn]PIP, n = 4, 6, 8), show high water solubility, efficient intercalation into DNA and good photocrosslinking efficiency of DNA. Bis(PsC4)PIP shows high lethality on bacteriophage T7 and can effectively inhibit the amplification of DNA by stopping the polymerase chain reactions in a short period of irradiation time.
