Non-nucleoside reverse transcriptase inhibitors (NNRTIs) of human immunodeficiency virus (HIV-1) bind directly to the reverse transcriptase (RT) of HIV-1 and block both RNA-dependent and DNA-dependent DNA polymerase activity by cleaving the catalytic end of the enzyme without competing with substrates or nucleoside triphosphates.

Azithromycin is a 15-membered macrolide antibiotic that has antibacterial effects on a variety of Gram-positive aerobic bacteria, Gram-negative aerobic bacteria, anaerobic bacteria, sexually transmitted disease microorganisms and other microorganisms. It mainly binds to the 50S subunit of the bacterial ribosome and inhibits RNA-dependent protein synthesis.
