A reverse transcriptase ribozyme
A highly evolved RNA polymerase ribozyme was found to also be capable of functioning as a reverse transcriptase, an activity that has never been demonstrated before for RNA. This activity is thought to have been crucial for the transition from RNA to DNA genomes during the early history of life on Earth, when it similarly could have arisen as a secondary function of an RNA-dependent RNA polymer...
متن کاملSynthetic chemistry-led creation of a difluorinated biaryl ether non-nucleoside reverse transcriptase inhibitor.
In the process of developing a series of novel, fluorinated biaryl ether NNRTIs, we fortuitously discovered derivative 20, which possesses excellent potency against both wild-type and clinically relevant mutations of the reverse transcriptase enzyme.

4 Optimal HIV-1 suppression often is difficult to achieve and maintain with currently available antiretroviral drugs, and viral resistance eventually emerges to many drugs. Chronic antiretroviral therapy is also associated with complications such as body fat redistribution, hypertriglyceridemia and hypercholesterolemia, abnormal glucose metabolism, lactic acidosis, pancreatitis, avascular necro...
متن کاملNucleoside Reverse Transcriptase Inhibitors
Although the incidence of HIV infection among women is increasing, the proportion of women in clinical trials that evaluate interventions for the treatment of HIV infection and its complications has historically been lower than the proportion of women in the HIV/AIDS patient population. Therefore, most knowledge about the efficacy of antiretroviral drugs and the adverse reactions associated wit...
متن کاملThe Discovery of Reverse Transcriptase
In 1961, Howard Temin began to gather evidence that was inconsistant with the central dogma. Temin, who devoted his life to studying RNA tumor viruses (now known as retroviruses), focused his early work on Rous sarcoma virus (RSV). This RNA virus is capable of transforming normal cells into cancerous cells. Temin felt the best explanation for the virus’s behavior was a model whereby the virus r...
