Which of the following antiviral medications prevents viral fusion with host cell membrane?
Maraviroc is a CCR5 coreceptor antagonist that blocks the receptor site the HIV virus needs to interact with in order to enter the cell. It prevents viral fusion with host cell membrane by binding to the CCR5 receptor on CD4+ T cells and macrophages.
Choice B is wrong because Abacavir is wrong because it is a nucleoside reverse transcriptase inhibitor (NRTI) that inhibits the enzyme reverse transcriptase, which converts viral RNA into DNA.
It does not prevent viral fusion with host cell membrane.
Choice C is wrong because Darunavir is wrong because it is a protease inhibitor (PI) that inhibits the enzyme protease, which cleaves viral proteins into functional units.
It does not prevent viral fusion with host cell membrane.
Choice D is wrong because Fosamprenavir is wrong because it is also a protease inhibitor (PI) that inhibits the enzyme protease.
It does not prevent viral fusion with host cell membrane.
