Feprazone
Based on 1 Customer Validation
Feprazone (DA2370; Prenazone), an analogue of Phenylbutazone (HY-B0230), is a nonsteroidal anti-inflammatory agent with analgesic and antipyretic activities. Feprazone acts by inhibiting the activity of cyclooxygenase (COX)-2. Feprazone ameliorates free fatty acid (FFA)-induced oxidative stress by reducing the production of mitochondrial reactive oxygen species (ROS). Feprazone can decrease the expression of MMP-2 and MMP-9. Besides, Feprazone can suppress adipogenesis and increase lipolysis in differentiating 3 T3-L1 cells. Feprazone also can be used to research atherosclerosis and obesity.

Biological Activity
COX, Reactive oxygen species, MMP[1]
Feprazone (2.5-10 μM; 48 h) rescues cell viability of FFAs-stimulated human aortic endothelial cells (HAECs)[1].
Feprazone (5, 10 μM; 24 h) reduces ROS production in HAECs to only 2.4- and 1.6-fold at 5 and 10 μM, respectively, while 300 μM FFA increases ROS production by 3.4-fold; also decreases the mRNA expression and secretion of cytokines CCL5, IL-6, and IL-8, as well as MMP-2 and MMP-9[1].
Feprazone (5, 10 μM; 6 h) decreases TLR4 and MyD88 activities, as well as reduces the phosphorylation of p65 and subsequent activation of NF-κB[1].
Feprazone (30 and 60 μM; 7 days) suppresses the adipogenesis in differentiating 3 T3-L1 cells; reduced the triglyceride content and increased lipolysis during 3 T3-L1 adipogenesis[3].

-
Cell Line:HAECs (stimulated with 300 μM FFAs)
-
Concentration:2.5, 5 and 10 μM
-
Incubation Time:48 h
-
Result:Rescued cell viability to 81 and 93% of baseline at 5 and 10 μM, while FFAs reduced the cell viability to 63% of baseline.
-
Cell Line:HAECs (stimulated with 300 μM FFAs)
-
Concentration:5 and 10 μM
-
Incubation Time:24 h
-
Result:Decreased the mRNA expression and secretion of cytokines CCL5, IL-6, and IL-8 in a dose-dependent manner.
Dose-dependently mitigated the VCAM-1 and ICAM-1 expression to only 1.7- and 1.8-fold, respectively, while FFA increased to 2.8- and 3.4-fold, respectively.
