(s4dU)35: a novel, highly potent oligonucleotide inhibitor of the human immunodeficiency virus type 1 reverse transcriptase. 1996

Oligodeoxycytidylates were converted to s4dUMP-containing oligomers by treatment with liquid H2S. The inhibitory potency of the modified oligonucleotides on human immunodeficiency virus type 1 reverse transcriptase depended on the chain length and on the percentage of modification. The most potent reverse transcriptase inhibitor was (s4dU)35. The inhibitory pattern was competitive, when either poly(A) x (dT)16 or poly(C) x (dG)l6 was used as template-primer (variable substrate), suggesting that the free enzyme interacts with (s4dU)35. The Ki values were 3.0 and 2.2 nM in the presence of poly(A) x (dT)16 and poly(C) x (dG)16, respectively.
