Quercetin significantly down regulates myofibroblast differentiation and fibrotic markers, such as α-smooth muscle actin (α-SMA) and Collagen III (Col III), in both HCFs and HKCs. Collagen III secretion was reduced 80% in both HCFs and HKCs following Quercetin treatment.Furthermore, Quercetin reduced lactate production by HKCs to normal HCF levels. Quercetin down regulated TGF-βR2 and TGF-β2 expression in HKCs suggesting a significant link to the TGF-β pathway. Quercetin is a key regulator of fibrotic markers and ECM assembly by modulating cellular metabolism and TGF-β signaling. Quercetin strongly abrogated PI3K and Src kinases, mildly inhibited Akt1/2, and slightly affected PKC, p38 and ERK1/2. Quercetin or the combined use of adenosine diphosphate and thromboxane A(2) inhibitors abrogated platelet spreading on these surfaces to a similar extent. The inhibitory effect of quercetin on platelet kinases blocks early signaling events preventing a complete platelet spreading. PKC inhibitors H-7 and quercetin protect BPAEC from TNF induced injuries and PKC play an important role in EC activation by TNF.

| Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
| Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 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 Compound A of 10 mg/kg.

| Terreic acid
Terreic acid is a quinone epoxide antibiotic and a potent Btk inhibitor, blocking the interaction between PKC and the PH domain of Btk.T Terreic acid also acts on HMC-1 human mast cell lysates, inhibiting the binding of GST-BtkPH to PKC with an IC50 of approximately 100 μM. Terreic acid also acts on HMC-1 human mast cell lysates to inhibit the binding of GST-BtkPH to PKC, with an IC50 of approximately 100 μM. In addition, Terreic acid simultaneously reduces the percentage of senescent cells and SASP expression in cells exposed to stress stimuli. |
| FOXO4-DRI acetate
FOXO4-DRI acetate is a cell-permeable peptide antagonist that blocks the interaction between FOXO4 and p53.FOXO4-DRI is an anti-aging peptide that induces apoptosis in senescent cells. |
| β-Galactosidase
β-Galactosidase is a glycoside hydrolase that hydrolyzes the β-glycosidic bond formed between galactose and its organic part. In Escherichia coli, the lacZ gene is the structural gene for β-galactosidase and can be used as part of the lac manipulator of the inducible system. β-Galactosidase hydrolyzes lactose to form glucose and galactose, which enter glycolysis, and also catalyzes the transgalactosylation of lactose to isolactose, which can be cleaved to monosaccharides. |
| Quercetin
Quercetin is a PI3K inhibitor with IC50 of 2.4-5.4 μM that has been shown to cause potent reversible inhibition of fatty-acid synthase. |
