Selective binding and reverse transcription inhibition of single-strand poly(A) RNA by metal TMPyP complexes.

Abstract

Ni-, Cu-, and Zn-TMPyP are capable of binding to single-strand poly(A) RNA with high preference and affinity and inhibiting the reverse transcription of RNA by both M-MuLV and HIV-1 reverse transcriptase. With 10 nM azidothymidine, the IC50 value of M-TMPyP could be lowered to 10(-1) μM order.
