体外研究

Prazosin (0,2.5,5,7.5,10,15,20,30,40 and 50µM) effectively inhibits the proliferation of U251 and U87 cells.Prazosin inhibits the migration and invasion of U251 and U87 cells.Prazosin treatment decreases the protein expression of components of the PI3K/AKT/mTOR signaling pathway.Prazosin (13.16 and 11.57µM for U251 and U87 cells,48 hours) decreases the expression levels of P70 and cyclin D1,which are downstream target genes of the PI3K/AKT/mTOR signaling pathway.

Cell Proliferation Assay

Cell Line:

U251 and U87 cells

Concentration:

0,2.5,5,7.5,10,15,20,30,40 and 50µM.

Incubation Time:

48 hours

Result:

The IC50s were 13.16±0.95 and 11.57±0.79µM for U251 and U87 cells,respectively.

Western Blot Analysis

Cell Line:

U251 and U87 cells

Concentration:

13.16 and 11.57µM for U251 and U87 cells,respectively

Incubation Time:

48 hours

Result:

Protein expression levels of Bax and active Caspase-3 were increased.Bcl-2 levels were also decreased after prazosin treatment (P<0.05).The expression of p-AKT and p-mTOR,P70 and cyclin D1 were decreased.

体内研究

Peripheral administration of Prazosin (0,0.5,1.0,1.5 or2.0mg/kg;i.p.) can suppress not only centralα1-adrenergicmediated hyperexcitability but also stress-induced anxiety.

Animal Model:

Fifty-five alcohol-naive male rats from the 60th generation of selective breeding for alcohol preference

Dosage:

0.5,1.0,1.5,or 2.0mg/kg

Administration:

Injected intraperitoneally (IP);0.5mg/mL;once a day at 15 min prior to onset of the daily two hour two-bottle choice,alcohol versus water,access period for two consecutive days and then three weeks later for five consecutive days.

Result:

Significantly reduced alcohol intake during the initial two daily administrations,and this reduction of alcohol intake was maintained for five consecutive days by daily prazosin treatment in the subsequent more prolonged trial.
