After 1991, several other nucleoside analogs were added to the anti-HIV arsenal, as were a new class of anti-HIV drugs called the non-nucleoside analog reverse transcriptase inhibitors which work in similar ways to the nucleoside analogs but which are more quickly activated once inside the bloodstream.

What is the class of antiviral drugs that prevents HIV infection?

Next to be developed were the class of antiviral drugs known as protease inhibitors, which were distinctly different from the reverse transcriptase inhibitors in that they do not seek to prevent infection of a host cell, but rather to prevent an already infected cell from producing more copies of HIV.

Why is combination therapy important?

By using more than one drug at a time, combination therapy is able to "pin down" HIV from more than one angle, so that even if one drug fails, another can continue to suppress viral replication.

What enzymes were used to map out the structure of HIV?

NCI scientists helped map out the structure of another essential viral enzyme, the HIV protease, to guide the design of a new class of HIV drugs.
