产品描述 Description

Tacrolimus (FK506), a macrolide antibiotic with potent immunosuppressive effects was isolated from Streptomyces tsukubaensis and has been previously used to prevent allograft and for treatment of autoimmune disorders in humans[1-3].

Tacrolimus(FK506) (0-2 μM;24 h)reduces synthesis of type I collagen protein without affecting expression of collagen mRNAs in Human lung fibroblasts (HLFs)[8]. T cell proliferation in response to ligation of the T cell receptor is inhibited by tacrolimus(FK506) [4]. Ttacrolimus(FK506) (concentration gradient;48 h)inhibited oral squamous cell carcinoma (OSCC) progression in vitro [9].

Tacrolimus (FK506) was given intramuscularly at the dose of 0.5 and 1.0 mg/kg for three days before burn injury. Thermal trauma to the skin caused a statistically significant increase in MPO activity and MDA content in remote organs. Tacrolimus (FK506) was effective in reducing lipid peroxidation and neutrophil infiltration especially at 24 h postinjury in lung, liver and kidney[5]. Tacrolimus (FK506) has the ability to down-regulate free radical levels in severe ischemia-reperfusion liver, and tachlimus has also been shown to be an effective inhibitor of cytokine response[6]. A study on pulmonary fibrosis in mice suggested that FK506 can be a potent antifibrotic agent [7]. Tacrolimus (FK506) treatment inhibited activation of HSCs or reduced their number in the liver. In vivo, administration of Tacrolimus (FK506) at a dose of 4 mg/kg(i.p.; 4 weeks) completely prevented development of alcohol/carbon tetrachloride induced liver fibrosis in rats[8].

实验参考方法 Experimental Reference Method

Cell experiment [1]:

Cell lines

Human lung fibroblasts (HLFs)

Preparation Method

Cells were incubated with the indicated concentrations of FK506 for 24 h. The cells were then washed 3 times with PBS and incubated for 3 h in serum free medium to accumulate secreted collagen.

Reaction Conditions

0-2 µM Tacrolimus (FK506);24 h

Applications

Animal experiment [1]:

Animal models

Male inbred alki Wistar rats weighing 150-200 g

Preparation Method

At the start of the study, drinking water was replaced by 5% ethanol as the only source of liquid and the rats were allowed to drink at will. Carbon tetrachloride (CCl4) was administered intraperitoneally (i.p.) at 0.5 µl/g of CCl4 in mineral oil twice a week for 4 weeks. Tacrolimus (FK506) was dissolved in 200 µL of Cremaphor and injected at daily dose of 4 mg/kg for 4 weeks (28 days). Control animals received by i.p. injections the Cremaphor vehicle. The groups were as follows: group 1:5% ethanol liquid+CCl4 injections; group 2:5% ethanol liquid+CCl4 injections+FK506 treatment; group 3: FK506 treatment only; group 4: vehicle only.

Dosage form

4 mg/kg;4 weeks (28 days);i.p.

Applications

Tacrolimus (FK506) treatment inhibited activation of hepatic stellate cells (HSC) or reduced their number in the liver. In vivo, administration of FK506 at a dose of 4 mg/kg completely prevented development of alcohol/carbon tetrachloride induced liver fibrosis in rats.
