| Description | Pimecrolimus (SDZ-ASM 981), a calcineurin inhibitor immunosuppressant, binds to the receptor macrophilin-12 (FKBP-12) forming a complex that blocks the calcium-dependent signal transduction cascade mediated by calcineurin. |
| In vitro | Pimecrolimus effectively alleviates allergic symptoms in a variety of (allergic) animals. Within the context of both the acute allergic dermatitis low-magnesium hairless rat model and the moderate allergic contact dermatitis mouse model, Pimecrolimus inhibits inflammatory responses and pruritic (itching) symptoms. |
| In vivo | In mast cells, Pimecrolimus inhibits the transcription and synthesis of cytokines, while simultaneously promoting the release of 5-hydroxytryptamine and β-hexosaminidase. In T lymphocytes, Pimecrolimus suppresses activation by inhibiting phosphatase activity, thereby blocking T-cell activation. |
