PDTC can enhance the cell apoptosis induced by TNF-α, which may be associated with the blocking of TNF-α-activated NF-κB signaling pathway by PDTC, the down-regulation of survivin expression, and up-regulation of caspase-3 expression.in NMSC PDTC acts as pro-oxidant and enhances IR-induced cell cytotoxicity by increasing H(2)O(2)formation and thiol oxidation.PDTC and MG132, inhibitors of NF-kappaB, block ET-induced vasodilation in isolated rat skeletal muscle arterioles.PDTC has effects at both the level of the aortic segment as well as the resistance arteriole.PDTC prevents induction of nitric oxide synthase (NOS) by inhibiting translation of NOS mRNA.PDTC induces apoptosis in rat smooth muscle cells and inhibits apoptosis in leukemia HL-60 cells.

|Cell Lines||Synovial tissues|
|Results||qRT-PCR showed that expression of IL-1α (Fig. 5r, u), IL-1β (Fig. 5s, v), and TNF-α (Fig. 5t, w) in response to LPS was significantly attenuated by PDTC and LY294002.|
|Source||Veterinary Microbiology (2018). Figure 6. PDTC (Abmole Bioscience, Houston, TX, USA)|
|Method||Detection of DC activation|
|Incubation Time||2 h|
|Results||The results indicated that Lp-HA-DCpep is more efficient in being englobed by DCs than Lp-HA and Lp determined by the FITC-Dextran uptake experiment (Fig. 6A) and thereby more effective in activating T cells as showed by MLR.|

|Cell Lines||mast cells|
|Incubation Time||30 minutes|
|Results||The S. aureus-induced production of TNF-α and CRAMP was significantly reduced by pretreatment with the specific PI3K inhibitor Wortmannin or the specific NF-κB inhibitor PDTC|
|Source||Sci Rep (2017). Figure 4. PDTC (AbMole BioScience Inc., Brussels, Belgium)|
|Method||Inhibitors of innate signalling pathways|
|Cell Lines||HEK cells|
|Incubation Time||24 h|
|Results||As expected, RELA knock-down and the presence of PDTC, an inhibitor of NFκB, resulted in substantial reduction of CXCL8 production in response to H7 flagellin by hTLR5 in the HEK background (p < 0.05)|
|Source||Vete Mic (2017). Figure 4. PDTC (Abmole Bioscience, Houston, TX, USA)|
|Method||Treatment by inhibitors|
|Incubation Time||48 h|
|Results||The PDTC (NF-kB inhibitor) treatment significantly decreased the MHC II, CD80, CD86, CD40 expressions. As to cytokine production (Fig. 4e–h), both inhibitors significantly restrained TNF-a, IFN-g and IL-6 secretions, with a minimal effect on IL-12p70.|

|Animal A (mg/kg) = Animal B (mg/kg) multiplied by||Animal B Km|
|Animal A Km|
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.
