Inhibition of human immunodeficiency virus in vitro by combinations of 3'-azido-3'-deoxythymidine and foscarnet.
نویسندگان
چکیده
We describe a synergistic effect of combinations of foscarnet and 3'-azido-3'-deoxythymidine against human immunodeficiency virus type 1 multiplication in cell culture, an additive effect of foscarnet and 3'-azido-3'-deoxythymidine triphosphate against human immunodeficiency virus type 1 reverse transcriptase, and a low toxicity in cell culture of combinations of the two drugs.

Synergistic inhibition of human immunodeficiency virus type 1 and type 2 replication in vitro by castanospermine and 3'-azido-3'-deoxythymidine.
Castanospermine and 3'-azido-3'-deoxythymidine (zidovudine) were evaluated in combination against human immunodeficiency virus (HIV) replication in vitro. Castanospermine and 3'-azido-3'-deoxythymidine inhibited HIV type 1 synergistically in acutely infected H9 cells. In addition, they synergistically inhibited both HIV type 1 and HIV type 2 in peripheral blood mononuclear cells. There were no ...
متن کاملRelationship between 3'-azido-3'-deoxythymidine resistance and primer unblocking activity in foscarnet-resistant mutants of human immunodeficiency virus type 1 reverse transcriptase.
Phosphonoformate (foscarnet) is a pyrophosphate (PP(i)) analogue and a potent inhibitor of human immunodeficiency virus type 1 (HIV-1) reverse transcriptase (RT), acting through the PP(i) binding site on the enzyme. HIV-1 RT can unblock a chain-terminated DNA primer by phosphorolytic transfer of the terminal residue to an acceptor substrate (PP(i) or a nucleotide such as ATP) which also interac...
متن کاملCombinations of isoprinosine and 3'-azido-3'-deoxythymidine in lymphocytes infected with human immunodeficiency virus type 1.
Since clinical trials are being planned with the immunomodulating drug isoprinosine combined with the antiviral drug 3'-azido-3'-deoxythymidine (AZT) in patients with acquired immunodeficiency syndrome (AIDS) and AIDS-related complex, it is important to determine the type of antiviral interaction produced by these drugs in vitro. Such a combined modality may not only produce enhanced antiviral ...
متن کاملThe thiocarboxanilide nonnucleoside inhibitor UC781 restores antiviral activity of 3'-azido-3'-deoxythymidine (AZT) against AZT-resistant human immunodeficiency virus type 1.
N-[4-Chloro-3-(3-methyl-2-butenyloxy)phenyl]-2-methyl-3-furanca rbothioamide (UC781) is an exceptionally potent nonnucleoside inhibitor of human immunodeficiency virus type 1 (HIV-1) reverse transcriptase. We found that a 1:1 molar combination of UC781 and 3'-azido-3'-deoxythymidine (AZT) showed high-level synergy in inhibiting the replication of AZT-resistant virus, implying that UC781 can res...
متن کاملIn vitro Assessment of Antiviral Activity of Cold Atmospheric Pressure Plasma Jet against the Human Immunodeficiency Virus (HIV)
Introduction: The human immunodeficiency virus (HIV) is a threat to global health and the need for finding new methods of antivirus research, in particular against HIV has increased in recent years. In this study, we investigated the ability of the cold atmospheric pressure plasma jet (CAPPJ) using helium to inhibit the replication of HIV virions. Methods: Single cycle replicable HIV (SCR-HIV) ...
