    • A method for measuring heterodimerization of HIV RT, which comprises the steps of:a) providing a first solution comprising p66 subunit homodimers in the presence of a dissociation agent; b) contacting the first solution with p51 RT subunits and incubating in the presence of a reassociation buffer to allow association of a complex of p66/p51 RT subunits, wherein one of the subunits comprises an affinity tag and the other of the subunits comprises a detectable label; c) contacting the incubate of step b) with an affinity medium under conditions that enable the p66/p51 complex to bind to the affinity medium; and d) determining the amount of complex formed by measuring the level of detectable label bound to the affinity medium (or by measuring the reconstituted RT polymerase activity). Steps a) to d) can be carried out in the presence or absence of a test compound followed by e) comparing the test compound sample to a control sample lacking the compound, whereby modulated p66/p51 complex formation in the test compound sample is indicative of the ability of the compound to modulate, inhibit or enhance heterodimerization.The method can be used to screen for inhibitors of HIV RT dimerization.

    • The present invention relates to novel oligonucleotide chimera used as therapeutic agents to selectively prevent gene transcription and expression in a sequence-specific manner. In particular, this invention is directed to the selective inhibition of protein biosynthesis via antisense strategy using oligonucleotides constructed from arabinonucleotide or modified arabinonucleotide residues, flanking a series of deoxyribose nucleotide residues of variable length. Particularly this invention relates to the use of antisense oligonucleotides constructed from arabinonucleotide or modified arabinonucleotide residues, flanking a series of deoxyribose nucleotide residues of variable length, to hybridize to complementary RNA such as cellular messenger RNA, viral RNA, etc. More particularly this invention relates to the use of antisense oligonucleotides constructed from arabinonucleotide or modified arabinonucleotide residues, flanking a series of deoxyribose nucleotide residues of variable length, to hybridize to and induce cleavage of (via RNaseH activation) the complementary RNA.
