[Inhibition of reproduction of the human immunodeficiency virus by sense and antisense oligodeoxynucleotides]. / Ingibirovanie reproduktsii virusa immunodefitsita cheloveka smyslovymi i antismyslovymi oligodezoksinukleotidami.

ABSTRACT

Inhibitory effects on human immunodeficiency virus (HIV) reproduction on lymphoid cell line MT-4 were characterized for antisense and sense oligodeoxynucleotides. It was established that antisense oligonucleotide pCGTAGTTCGTCGAGGTCCGT (MP-20) (ID50 = 0.1 microM) is a more effective HIV inhibitor than the previously described pTGGCGTACTCACCAGTCGCCGC (DSS-22) (ID50 = 4.7 microM) and pTTTTTTTTTTTTTTTT (PA-16) (ID50 = 8.0 microM). A sense oligonucleotide pGCATCAAGCAGCTCCAGGCA (PM-20) (ID50 = 0.5 microM) complementary to the region of the start of translation of the open reading frame on the (+)-chain virus DNA was also investigated. Specificity of the anti-HIV-I action of oligonucleotides was confirmed by experiments with HIV-II.
