Fasudil hydrochloride is a protein kinase inhibitor, i.e., an intracellular calcium ion antagonist, which dilates blood vessels and inhibits vasospasm by blocking the final stage of vasoconstriction (myosin light chain phosphorylation).

Tenofovir alafenamide fumarate is an anti-hepatitis B virus drug. As a prodrug of tenofovir, it enters the liver cells through passive diffusion and liver uptake transporters, and forms the active metabolite tenofovir diphosphate through hydrolysis and phosphorylation, which inhibits HBV reverse transcriptase and thus exerts an antiviral effect.

The dipeptide compound isolated from the culture medium of Streptomyces ofivorecticuli can competitively inhibit aminopeptidase B and leucine peptidase. It can enhance the function of T cells, enhance the killing activity of NK cells, and increase the synthesis of colony stimulating factors to stimulate the regeneration and differentiation of bone marrow cells. It may interfere with the metabolism of tumor cells, inhibit tumor cell proliferation, cause tumor cell apoptosis, activate human cellular immune function, stimulate the production and secretion of cytokines, and promote the production and proliferation of anti-tumor effector cells.
