Nucleosidi

Emtricitabine is a synthetic nucleoside analog of cytidine. It is used in the treatment of HIV infection and hepatitis B virus infection. Emtricitabine binds to human DNA polymerase, preventing the incorporation of viral DNA into the host cell's genome. This prevents the virus from multiplying and reproducing, thereby inhibiting the spread of HIV in humans. The drug has been shown to inhibit replication at all stages of HIV-1, including reverse transcription and integration into host cell DNA. Emtricitabine also inhibits replication of other viruses such as herpes simplex virus type 1 (HSV-1) and hepatitis C virus (HCV). Emtricitabine is a prodrug that must be activated by phosphorylation before it can be incorporated into DNA. This activation requires tenofovir alafenamide hemifumarate as an activator, which is an experimental drug with improved bioavailability, reduced renal clearance, and
