Biological Activity

SD-208 blocka TGF-beta-induced phosphorylation of the receptor-associated Smads, Smad2 and Smad3, and stimulates epithelial-to-mesenchymal transdifferentiation, migration, and invasiveness into Matrigel in vitro.In the murine aortic allograft model, SD-208 effectively reduces the formation of intimal hyperplasia of transplant arteriosclerosis (TA).

Cell Lines EAN rats

Incubation Time 12 day
Results In both the SD-208 alone and RvD1 + SD-208 groups, EAN rats showed much more severe neurological scores and significantly prolonged disease duration, not only compared with the RvD1 + vehicle group, but also compared with the vehicle-alone group (Fig. 5B), suggesting that the inhibition of TGF-β signaling not only abolished the exogenous RvD1 effects, but also may suppress endogenous RvD1 functions.
Cell Experiment
Cell lines Murine SMA-560 or human LN-308 glioma cells
Preparation method Proliferation.
Glioma cells were cultured in the absence or presence of SD-208 (1 μmol/L) for 48 hours. The cells were pulsed for the last 24 hours with [methyl-3H]thymidine (0.5 μCi) and harvested (Tomtec, Hamden, CT), and incorporated radioactivity was determined in a liquid scintillation counter (Wallac, Turku, Finland).

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
