An antiretroviral composition for inhibiting the action of reverse transcriptase include a nucleoside analog containing a six-carbon levo hexose sugar, for example, L-rhamnose or L-fucose. Treatment is achieved by delivering the antiretroviral to the infected system, wherein the reverse transcription process is inhibited via steric hindrance, halting the viral RNA replication. Delivery may be accomplished by conventional methods, such as via oral dosing or injection. Additional delivery methods are also contemplated, including packaging in liposomes and protein targeting. The composition and method are also useful for inhibiting the proliferation of cancer cells by halting the transcription process.
A retroviral inhibiting agent comprising a DNA segment complementary to HTLV-III (HIV) RNA bases 822-847 having at least one nucleotide containing a six-carbon levo hexose sugar moiety selected from a group consisting of L-rhamnose and L-fucose.
A cell comprising retroviral RNA, reverse transcriptase, and an antiretroviral agent comprising an adenosine analog containing a six-carbon levo sugar moiety selected from a group consisting of L-rhamnose and L-fucose.
A cell comprising retroviral RNA, reverse transcriptase, and an antiretroviral agent comprising an adenosine analog containing an L-rhamnose moiety.
A cell comprising retroviral RNA, reverse transcriptase, and an antiretroviral agent comprising a nucleoside analog selected from a group consisting of 1′-adenyl-L-rhamnose, 1′-cytodinyl-L-rhamnose, 1′-guanyl-L-rhamnose, 1′-thymidyl-L-rhamnose, and 1′-uridinyl-L-rhamnose.
A composition for inhibiting a retrovirus from replicating in a cell, the composition comprising an antiretroviral agent packaged within a liposome, the antiretroviral agent comprising a nucleoside analog containing a six-carbon levo sugar moiety selected from a group consisting of L-rhamnose and L-fucose.
