生物活性

Amifostine thiol (WR-1065) dihydrochloride can protect normal tissues from the toxic effects of certain cancer drugs and activate p53 through a JNK-dependent signaling pathway.

IC50 & Target

p53[1]

体外研究
(In Vitro)

The DNA-binding activity is increased in a Amifostine thiol dihydrochloride (Amifostine thiol) concentration-dependent manner. Cells treated with 1 mM Amifostine thiol dihydrochloride for 24 h reveal that all of the p53-induced genes analyzed are transactivated following Amifostine thiol dihydrochloride treatment, in a p53-dependent manner. Significantly, treatment with Amifostine thiol dihydrochloride leads to a 3-fold increase in luciferase expression driven by AP-1, and a 5-fold increase when this reporter gene is driven by NF-κB, when these values are normalized to the level of the cotransfected β-galactosidase gene[2].

体内研究
(In Vivo)

The results show that Amifostine thiol dihydrochloride (Amifostine thiol) attenuates the severity of 6-OHDA-induced catalepsy (P<0.001) when compare with 6-OHDA-lesioned rats. Also it has been observed that Amifostine thiol dihydrochloride improves catalepsy in dose dependent manner (P<0.001). Pretreatment with three different doses of Amifostine thiol dihydrochloride (20, 40 and 80 μg/2 μL/rat) for 3 days before 6-OHDA administration, significantly (P<0.001) elevates SOD activity and restores it to normal range compare with 6-OHDA lesioned rats[3].

Kinase Assay
[2]

For Western analysis, cells are treated with 1 mM WR-1065 dihydrochloride (WR-1065) for 24 h, and subconfluent cultures of cells are harvested and lysed in RIPA buffer supplemented with protease inhibitors. Protein concentrations are determined by a detergent-compatible assay. Western blots are blocked and incubated in antibody in PBS/0.2% Tween 20/5% nonfat dry milk. Blots are incubated with 1 μg/mL antibody for 1 h at room temperature, followed by washing in PBS/0.2% Tween 20 and incubation in peroxidase-conjugated secondary antibody and chemiluminescence detection[2].

Cell Assay
[2]

To test the effects of paclitaxel in the presence or absence of WR-1065 dihydrochloride (WR-1065) on cell growth, cells are seeded in 96-well tissue culture dishes at 20% confluence and allowed to attach and recover for at least 24 h. Varying combinations of paclitaxel alone or in combination with a 60 min pretreatment with 1 mM WR-1065 dihydrochloride are then added to each well, and the plates are incubated for an additional 48 h or 72 h. The number of surviving cells is determined by staining. The percentage of cells killed by paclitaxel and/or WR-1065 dihydrochloride is calculated as the percentage decrease in sulforhodamine B binding compare with control cells[2].

Animal Administration
[3]

Seventy two rats are divided randomly into 9 equal groups: 1) Control group receives no injection and is left untreated for the entire period of the experiment as intact animals; 2) Sham operated group is subjected only to surgical procedure; 3) Vehicle (saline)-treated group receives 2 μL saline (intra-SNc); 4) Lesioned group receives 6-hydroxydopamine; 5) Vehicle+6OHDA group receives saline as a vehicle 3 days once daily (2 μL/rat) before 6-OHDA injection; 6 to 8) Rats in these groups are pretreated with intra-SNc injection of WR-1065 dihydrochloride (WR-1065) (20, 40 and 80 μg/2 μL/rat) 3 days before 6-OHDA injection; 9) Non-lesioned animals receive intra-SNc injection of WR-1065 dihydrochloride (80 μg/2 μL/rat) for three days[3].
