PP2 is a potent, reversible, ATP-competitive, and selective inhibitor of the Src family of protein tyrosine kinases. PP2 strongly inhibits the kinases Lck (IC50=4 nM), Fyn (5 nM) and Hck (5 nM). PP2 also inhibits anti-CD3-stimulated tyrosine phosphorylation of human T-cells with an IC50 value of 600 nM. PP2 does not significantly affect the activity of EGFR kinase (IC50 = 480 nM), JAK2 (IC50 > 50 µM), or ZAP-70 (IC50 > 100 µM).

|Cell Lines||MDA-MB-231 cells|
|Concentrations||PI3K (10 µM LY294002), Akt (10 µM MK-2206) or mTOR (10 µM rapamycin)|
|Results||As shown in Figure 11. Pretreating MDA-MB-231 cells with the specific inhibitors of PI3K (10 µM LY294002), Akt (10 µM MK-2206) and mTOR (10 µM rapamycin) completely abolished the LSS-induced MT1-MMP expression, indicating that the PI3K/Akt/mTOR pathway is required for LSS-induced MT1-MMP expression.|

|Method||Cell motility assay|
|Cell Lines||MDA-MB-231 cells|
|Concentrations||PI3K (10 μM LY294002), Akt (20 μM MK-2206), mTOR (10 μM rapamycin, Rap), FAK (10 μM PF573228) or Src (10 μM PP2)|
|Results||"Notably, inhibitors of PI3K (LY294002), Akt (MK-2206) and mTOR (rapamycin) markedly decreased the LSS-induced wound closure activity. However, pretreatment with inhibitors of FAK (PF573228) and Src (PP2) has no effect on the LSS-induced cell motility (Figure 1B). It is suggested that PI3K, Akt and mTOR might be participated LSS-induced cell motility in an FAK and Src-independent manner. "|

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.
