Previous work has shown that novel amphipathic oligo and polyribonucleotides exhibiting secondary structure in solution are potent inhibitors of HIV and HCMV replication and cytopathicity in tissue culture. It was hypothesized that the mechanism(s) of action for these compounds might be inhibition of retroviral reverse transcriptase (RT) and/or viral uptake by cells. Pursuit of the essential pharmacophore has led to the discovery of poly (1-propargylinosinic acid) (10), an HIV and HCMV-active polyribonucleotide lacking the secondary structure previously thought to be essential for the observed antiviral activity.

D003587	Cytomegalovirus	A genus of the family HERPESVIRIDAE, subfamily BETAHERPESVIRINAE, infecting the salivary glands, liver, spleen, lungs, eyes, and other organs, in which they produce characteristically enlarged cells with intranuclear inclusions. Infection with Cytomegalovirus is also seen as an opportunistic infection in AIDS.

D000998	Antiviral Agents	Agents used in the prophylaxis or therapy of VIRUS DISEASES. Some of the ways they may act include preventing viral replication by inhibiting viral DNA polymerase; binding to specific cell-surface receptors and inhibiting viral penetration or uncoating; inhibiting viral protein synthesis; or blocking late stages of virus assembly.
