Cell experiment [1]: | |
Cell lines |
MDA-MB-231 human breast cancer cell line |
Preparation Method |
Cells were treated at the logarithmic phase of the growth with various doses of SB 203580 (0.1, 0.5, 1, 5, 10, 25, 50, 100 µM) for 24 h |
Reaction Conditions |
0.1, 0.5, 1, 5, 10, 25, 50, 100 µM for 24 h |
Applications |
SB 203580 did not cause significant cytotoxicity on human MDA-MB-231 breast cancer cell line at low concentrations (0.1-10 µM) as compared to vehicle-treated (0.5% DMSO) control cells. However, the cytotoxic effects of both inhibitors were observed with higher concentrations of 25, 50 and 100 µM.. |
Animal experiment [2]: | |
Animal models |
Male Balb/c mice |
Preparation Method |
Treatments with 2% DMSO alone or SB 203580 dissolved in 2% DMSO were given 1 h before and 1 h and 24 h after DENV infection intravenously. The volume of all injections was 0.4 ml. At 7 days after infection, the mice were euthanized with an overdose intraperitoneal injection of sodium pentobarbital anesthesia. |
Dosage form |
5 mg/kg/d for 7 days, infection intravenously |
Applications |
After the DENV-infected mice were treated with SB 203580, their liver AST levels were significantly reduced, but the changes in ALT were failed to reach statistical significance |

SB 203580 is a specific inhibitor of p38-MAPK (Mitogen-activated Protein Kinase) pathway [1,2]. SB 203580 inhibits p38 kinase in a manner competitive with ATP with a Ki of 21 nm [2].
SB 203580 inhibit the proliferation of human breast cancer cell line MDA-MB-231 with the IC50 value of was 85.1 µM [3]. SB 203580 inhibited IL-10 production by monocytic WEHI 274.3 cells expressing WT-p38α MAPK in a dose-dependent manner with greater than 95% inhibition at 5 µm and with an IC50 of 0.1µM [4]. IL-2-induced proliferation of primary human T cells, murine CT6 T cells, or BAF F7 B cells is prevented by the p38 MAP kinase inhibitor SB 203580 with an IC50 of 3-5µM [5].
SB-203580 demonstrated moderate to high clearance in all species tested in vivo, with non-linear elimination observed in the rat at plasma concentrations > 1000ng ml -1. Although good solution bioavailability was observed in non-rodents (78% in dog, 32% in monkey), lower and more variable bioavailability was observed in the rat and mouse (3-48%) [6]. SB 203580 treatment significantly improve the white blood cell (WBC) and platelet counts decreased significantly in the DENV-infected mice, suggesting leucopenia and thrombocytopenia, respectively [7].

General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |
