Protocol

Cell experiment:

Cell lines

Liver slices, human lung fibroblasts

Preparation method

The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reacting condition

2 μM and 4 μM for 3 days

Applications

FK506 reduced type I collagen synthesis in liver slices cultured in vitro [1]. Moreover, FK506 (2 μM) decreased the type I collagen protein synthesis without affecting expression of collagen mRNAs [2].

Animal experiment:

Animal models

Rats model

Dosage form

4 mg/kg; i.p. injections, daily dose for 4 weeks; or 1, 2 and 3 mg/kg, p.o. for 10 consecutive days

Applications

FK506 (4 mg/kg) prevented early stages of ethanol induced hepatic fibrosis by targeting LARP6 dependent mechanism of collagen synthesis in rats [1]. Moreover, FK506 (2 and 3 mg/kg) treatment resulted in attenuation of arterial ischemic reperfusion (I/R) induced axonal degeneration and histopathological alterations in rats [2].

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

Background

Tacrolimus (FK506) is a potent and selective inhibitor of T-lymphocyte and the macrolide immunosuppressant [1].

In vitro, Tacrolimus (FK506) has been reported to inhibit the interleukin 2(IL-2) production and the response of mixed lymphocyte culture. In addition, Tacrolimus (FK506) added to the cell cultures has been revealed to inhibit murine or human mixed lymphocyte reactivity and the generation of cytotoxic T cells. Furermor, Tacrolimus (FK506) has also been reported to dose-dependently suppress the production of various cytokines including IL-2, IL-3, IL-4, and γ-interferon, in response to different stimulis. Besides, Tacrolimus has shown its efficacy in the prevention of allograft rejection in animal transplant models. Tacrolimus has been found to be significantly efficient in experimental hepatic allografts, and has hepatotrophic properties [1].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
