Mechanism

Promotes immature T-cell maturation in the thymus, raising CD3+/CD4+ marker expression and adjusting the CD4+/CD8+ ratio; believed to bind DNA and nuclear proteins to activate JAK/STAT signaling, increasing IL-2 and IFN-γ output, boosting NK-cell and macrophage activity, and reducing inflammation via NF-κB modulation.

Safety file

Reported as well tolerated with low toxicity in Russian use, but not confirmed by large modern Western clinical trials.
