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.

In a randomized trial, it was subsequently shown to improve survival of AIDS patients. In 1987, it became the first drug approved by the U.S. FDA for treatment of the disease. AZT was subsequently shown to markedly reduce the perinatal transmission of HIV.
What enzymes did the NCI develop?
NCI’s strong industry collaborations helped speed patient access to the new drugs. The NCI researchers first focused on a viral enzyme called reverse transcriptase that HIV needs to multiply. They developed an assay to test the utility of drugs against HIV and gathered a number of promising compounds to test.
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. When combined with reverse transcriptase inhibitors, protease inhibitors, developed in the mid-1990s, dramatically suppressed replication of the virus, often reducing it to undetectable levels.

Who invented AZT?
Azidothymidine (AZT), a compound first synthesized by Jerome Horowitz, Ph.D., in 1964 as an anti-cancer drug, was among the drugs initially tested. In a preliminary clinical trial done largely in the NIH Clinical Center, NCI scientists showed that AZT could improve the immune function of AIDS patients. In a randomized trial, it was subsequently ...
Is AZT effective for AIDS?
Because AZT was not entirely effective by itself, NCI scientists continued to develop and test other drugs to treat AIDS, including the reverse transcriptase inhibitors didanosine (ddI) and zalcitabine (ddC).

When was AZT first used?
AZT, or azidothymidine, was originally developed in the 1960s by a U.S. researcher as way to thwart cancer; the compound was supposed to insert itself into the DNA of a cancer cell and mess with its ability to replicate and produce more tumor cells. But it didn’t work when it was tested in mice and was put aside.

Amit Chitnis, Diana Rawls, and Jim Moore proposed that HIV may have emerged epidemically as a result of harsh conditions, forced labor, displacement, and unsafe injection and vaccination practices associated with colonialism, particularly in French Equatorial Africa.
Why did HIV emerge?
In several articles published since 2001, Preston Marx, Philip Alcabes, and Ernest Drucker proposed that HIV emerged because of rapid serial human-to-human transmission of SIV (after a bushmeat hunter or handler became SIV-infected) through unsafe or unsterile injections.
How much does HIV affect heterosexuality?
These diseases increase the probability of HIV transmission dramatically, from around 0.01–0.1% to 4–43% per heterosexual act, because the genital ulcers provide a portal of viral entry, and contain many activated T cells expressing the CCR5 co-receptor, the main cell targets of HIV.

Still Not A Cure
- In all, the simultaneous treatment of people with HIV with different classes of antiviral drugs is among the most significant scientific advances in the history of the AIDS epidemic. Five years after its widespread use, combination antiviral therapy has demonstrated enormous potential, eliminating early fears that it would prove to be yet another dead-end in the treatment of HIV infe…
The Post-Vancouver State of Combination Treatment
- Overall, for people living with HIV disease, as well as professionals working with them, the news about the effectiveness of combination therapies that emerged in 1996, particularly from that year's International AIDS conference in Vancouver, was heartening but also confusing. During and after the conference, mainstream media reporting made it seem as if a total cure had been disc…
