Preparazione delle soluzioni stock

Attività biologica

Descrizione Il Tacrolimus (FK506) è un lattone macrolide a 23 membri, riduce l'attività di peptidil-prolil isomerasi nelle cellule T legandosi all'immunofilina FKBP12 (FK506 binding protein), creando un nuovo complesso. Il Tacrolimus inibisce anche l'attività phosphatase della calcineurin. Il Tacrolimus induce l'autophagy delle cellule endoteliali vascolari.
Target
FKBP12
(T cells)		 calcineurin
In vitro

Tacrolimus (FK506) and cyclosporin A block translocation of the cytoplasmic component without affecting synthesis of the nuclear subunit in T lymphocytes. This compound prevents T-cell proliferation by inhibiting a Ca(2+)-dependent event required for induction of interleukin-2 transcription. It binds to distinct families of intracellular proteins (immunophilins) termed cyclophilins and FK 506-binding proteins (FKBPs). Tacrolimus specifically inhibits cellular calcineurin at drug concentrations that inhibit interleukin 2 production in activated T cells. It and CsA exert nearly identical biological effects in cells by inhibiting the same subset of early calcium-associated events involved in lymphokine expression, apoptosis, and degranulation. This compound binds to a family of intracellular receptors termed the FK-506 binding proteins (FKBPs).

In vivo

Tacrolimus (FK506) results in an increase in the paw and tail withdrawal threshold as revealed by behavioral pain assessment in rats against hyperalgesic and allodynic stimuli. It also leads to a decrease in the serum nitrate and thiobarbituric acid reactive substance (TBARS) levels along with reduction in tissue myeloperoxidase (MPO) and total calcium levels, whereas, rise in tissue reduced glutathione levels in rats. This compound ameliorates the increase in the neuronal edema and axonal degeneration in rats with ischemia reperfusion (I/R).

<p>Effect of FK506 on cytosolic calcium homeostasis induced by TG and thrombin in human platelets. (A-B) Human platelets were suspended in a Ca 2+-free medium (100 µM of EGTA was added as indicated by arrowhead), and preincubated for 5 min at 37oC in the absence (solid black traces) or presence of increased concentrations (0.01-100 µM) of FK506 (light-doted and dark solid-grey traces, respectively). Cells were then stimulated with TG (200 nM; A) or Thr (0.1 U/mL; B) and 3 min later 300 μM of CaCl2 was added to extracellular medium to visualize calcium entry.</p>

<p>Release of immune mediators after Tacrolimus application. Tacrolimus was applied to IL-1β/TNFα pretreated (diamonds) or unprimed (squares) Caco-2 monolayer in the indicated concentrations. Caco-2 cells in transwell inserts were transferred to culture vessels filled with heparinized whole blood of three different healthy donors (indicated by their ID-numbers). After 1 h the whole blood in the lower compartment was stimulated by LPS/SEB/anti-CD28 injection. After 6 h the Caco-2 cells were removed and the whole blood was further incubated for 18 h. Immune mediators were quantified in plasma. Depicted are stimulation indices of single experiments. I IL-17A, J TARC, K IL-13, L IL-1ra, M IL-5, N IL-10.</p>
