Ibudilast
Based on 11 publication(s) in Google Scholar
Ibudilast (KC-404; AV-411; MN-166) is a cyclic AMP phosphodiesterase (PDE) inhibitor. Ibudilast has platelet anti-aggregatory effects. Ibudilast can be used for the research of asthma for its inhibitory effects on tracheal smooth muscle contractility. Ibudilast may be a useful neuroprotective and anti-dementia agent counteracting neurotoxicity in activated microglia.

Description
IC50 & Target
phosphodiesterase[1]
In Vitro
Ibudilast (1~100 μM; 24 hours; microglia) suppresses both IL-1β and IL-6 production at 100 μM, and significantly suppresses TNF-α production at 10 and 100 μM[1].
Ibudilast (1~100 μM; 48 hours; neuronal cells) significantly increases the neuronal survival rate. Ibudilast (1~100 μM; 48 hours; microglia) inhibits the production of superoxide and NO[1].
Ibudilast upregulates the production of IL-10 in a dose-dependent manner. Ibudilast increases NGF mRNA and protein levels and GDNF and NT-4 mRNA expression. Ibudilast decreases the apoptotic changes observed in the neuronal cells in a dose-dependent manner[1].

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.
