Description

Ribavirin (ICN-1229) is an antiviral agent against a broad spectrum of viruses including HCV, HIVl, and RSV. Ribavirin also has anti-orthopoxvirus and anti-variola activities.

In Vitro

Treatment of LPS-stimulated microglia with 5, 10 and 20 μM Ribavirin (ICN-1229) induces reduction of NO₂ levels for 43% (p<0.05), 53% (p<0.05) and 59% (p<0.05), respectively. Ribavirin (ICN-1229) (10 mM) insignificantly decreases the cell surface area in non-stimulated culture, but significantly reduces cell surface area (by 32%, p<0.05) in LPS-stimulated microglia^[3]. Ribavirin (ICN-1229) is active against DENV, with an EC₅₀ of 3 μM in A549 cells, and combination of CM-10-18 with Ribavirin (ICN-1229) demonstrates a clear enhancement in the reduction of virus replication^[4].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

ALT, AST activities and bilirubin levels are significantly loared by administration of JAT in combination with interferon and Ribavirin (ICN-1229) (p<0.01). JAT, interferon or ribavirin alone with CCl₄, livers appear to exhibit some liver protection against CCl₄ as evident by the presence of normal hepatic cords, absence of necrosis and lesser fatty infiltration. Groups treated with JAT, Peg-interferon and Ribavirin (ICN-1229) separately or in combination shows reduction in the expression of TGF- β and Bax. In the group treated by triple combination of interferon, Ribavirin (ICN-1229), and JAT, the expression level of p53 is markedly reduced^[1].
Ribavirin (ICN-1229) capsules (400 mg of ribavirin)-treated Wistar rats show a significant decrease in activin-A and significant increase in follistatin at the serum and liver levels. Ribavirin (ICN-1229) has strong antiviral activity only when ribavirin is combined with either IFN-α or Peg-IFN-α^[2].
Ribavirin (40 mg/kg, p.o.) significantly improves the antiviral efficacy of CM-10-18 in mice. Ribavirin (ICN-1229) inhibits DENV virus infection in cultured cells, but it is ineffective in reducing viremia in monotherapy^[4].

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.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (10.24 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.
Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (10.24 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.
Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 2.5 mg/mL (10.24 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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.

Cell Assay ^[3]	The effect of Ribavirin (ICN-1229) on microglial cell viability is evaluated by the sulforhodamine B (SRB) chemosensitivity assay. Briefly, LPS-stimulated microglial cells are incubated for 48 h in the presence or absence of Ribavirin (ICN-1229). Afterward, the cells are fixed in 10% (w/v) trichloroacetic acid for 1 h at 4°C, rinsed in tap water and stained with 0.4% (w/v) SRB in 1% acetic acid (100 μL/well) for 30 min at room temperature (RT). The cells are then rinsed three times in 1% acetic acid to remove the unbound stain. The protein bound stain is extracted with 200 μL 10 mM Tris base (pH 10.5) per well. The optical density is read at 540 nm, with correction at 670 nm. The results are presented as percentage of the control (non-stimulated/untreated microglial cells), that is arbitrarily set to 100%. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
Animal Administration ^[4]	The in vivo efficacy experiments are largely performed, using a dengue viremia model in AG129 mouse (defective of both type I and type II interferon receptors). Each experiment contains 6 mice (7 to 8 week-old) per dosing group. The mice are challenged with DENV (serotype 2, TSV01 strain), at 5×10⁶ pfu/mouse via i.p. injection. Imino sugars are dosed twice daily at 12 hr intervals, and ribavirin is dosed once daily, for 3 consecutive days post-infection. Blood samples are drawn 3 days post-infection for determination of plasma virus titer by plaque assay. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
