Biological Activity for C3

C3 is a selective microsomal prostaglandin E synthase 1 (mPGES-1) inhibitor (IC50 values are 90 and 900 nM for rat and human mPGES-1, respectively). Displays selectivity for mPGES-1 over COX-1, COX-2, PGIS, hPGDS and iPGDS (% inhibition values are 15, 18, 0, 0 and 60 % inhibition at 50 μM, respectively). Reduces PGE2 production in vitro and in a localized inflammation animal model. Elevates CD80 expression by tumor associated phagocytes in vitro. Also decreases vascular contractility, in ex vivo human vessels.

C3 inhibits LPA induced COX-2 expression in osteosarcoma cells.
By Christopher Trummer on 10/23/2018
Assay Type: In Vitro
Species: Human
Cell Line/Tissue: Osteosarcoma

MG-63 cells were treated with LPA (10 µM) alone or in combination with C3 (20 µM), PTX (Pertussis Toxin, 400 ng/ml) or H2L 5765834 (20 µM) for 3 h to follow COX-2 expression using Western blot. C3 inhibited COX-2 expression induced by LPA.
