Emtricitabine
Based on 8 publication(s) in Google Scholar
Emtricitabine is a nucleoside reverse transcriptase inhibitor (NRTI) with an EC50 value of 0.01 μM in PBMC cells. Emtricitabine inhibits HIV reverse transcriptase, preventing RNA from being transcribed into DNA. Emtricitabine has low brain permeability (logP <0)[1][2][3][4][5].

In Vitro
Emtricitabine has in vitro activity against both laboratory strains of HIV-1 and HIV-2 and clinical isolates of HIV-1. The 50% effective concentration (EC50) ranges from 0.002 to 1.5 μ mol/L, depending on the viral isolate and cell line used. Emtricitabine demonstrates in vitro synergy with zidovudine and stavudine and additive in vitro activity when combines with zalcitabine or didanosine[1].

Levels of Aβ 1-40 from the media of cultured neurons after ART compounds treatment for 48 h were detected by ELISA. Δ secreted Aβ1-40 represented the difference of secreted Aβ1-40 between ARTs and DMSO (vehicle controls). Lamivudine (1 μM), Emtricitabine (0.1 μM), tenofovir disoproxil (10 μM), ritonavir (1 μM), nelfinavir (1 μM), darunavir (0.1 μM), efavirenz (1 μM), nevirapine (1 μM), dolutegravir (1 μM) and elvitegravir (1 μM) significantly increased secreted Aβ1-40, whereas zidovudine (10 μM) and abacavir (10 μM) significantly decreased secreted Aβ1-40.

Both Cyclophilin Inhibitors and Direct-Acting Antivirals Prevent PKR Activation in HCV-Infected Cells. [Abstract]2014 Mar 7:8:1-8. PMID: 24799968
Emtricitabine purchased from MedChemExpress. Usage Cited in: Open Virol J. 2014 Mar 7:8:1-8. [Abstract]
The PKR activation block is not unique to CypI, DAAs also prevent the IFN-induced PKR activation in HCV-infected cells. JFH-1-infected Huh7.5.1 cells are treated with or without CypI (cyclosporine A and alisporivir), DAAs (the HCV NS5A inhibitor daclatasvir and the HCV protease inhibitor telaprevir) and an HIV-1 inhibitor (reverse transcriptase inhibitor Emtricitabine). Results are representative of 4 independent experiments.

In Vivo:
Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (10.11 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (10.11 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
