| Description | Rifampicin (Rifamycin AMP) is a broad-spectrum antibiotic. Rifampicin has a strong antibacterial effect against Mycobacterium tuberculosis and is also effective against gram-positive and gram-negative bacteria and viruses. |
| Targets & IC50 | OATP1B1:1.2–1.5 μM, HepG2 cells:145.33 μM, Vero cells:> 10 μg/mL, HeLa cells:270 μg/mL, Huh7 cells:> 20 μM, Osteoblast:130 μg/mL, Hepatocyte cells:> 20 μM, MDCK cells-II:> 20 μM, J774 cells.A1:> 64 μg/mL, THP-1 cells:0.0018 μg/mL, PBMC cells:62.92 μg/mL, MG-63 cells:240 μg/mL, Macrophages:> 100 μM, MRC5 cells:> 100 μM, HEK293 cells:0.3 μM |
| In vitro | METHODS: PC12 cells were treated with Rifampicin (25-100 µM) for 3-24 h. The expression levels of target proteins were detected by Western Blot. RESULTS: At 6 h of incubation, Rifampicin induced a significant increase in GRP78 protein expression in PC12 cells. Prolonged incubation with Rifampicin further enhanced the induction of GRP78 up to 24 h. PC12 cells showed a dose-dependent induction of GRP78 when incubated with Rifampicin at concentrations in the 25-100 µM range. [1] METHODS: Human colon cancer cells LS180 were treated with Rifampicin (10 µM) for 24-144 h. Gene levels were measured by RT-PCR. RESULTS: The total expression of NR1I2 mRNA was reduced by 40% after 24 h of Rifampicin treatment, and the expression of PXR.3 mRNA was reduced by 45% after 24 h of Rifampicin treatment. [2] |
| In vivo | Rifampicin (200, 400 mg/kg) can induce fatty liver at high concentrations [4]. Rifampicin (30 mg/kg, i.p.) treatment of S464P biofilms in vivo causes a slight decline in bioluminescence from these catheters compared with the parental signal, but it does not affect bioluminescence in mice infected with mutant H481Y [5]. |

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 
10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH2O , the resulting working solution concentration would be 2 mg/mL.Dissolve 2 mg of the compound in 100 μL DMSO to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
1) Add 100 μL of the DMSO stock solution to 400 µL PEG300 and mix thoroughly until the solution becomes clear.
2) Add 50 µL Tween 80 and mix well until fully clarified.
3) Add 450 µL Saline,PBS or ddH2O and mix thoroughly until a homogeneous solution is obtained.
