Biological Activity for FR 180204

FR 180204 is a selective ERK inhibitor (IC50 values are 0.14 and 0.31 μM for ERK2 and ERK1 respectively). Displays 30-fold selectivity for ERK over p38α (IC50 = 10 μM); displays no activity against human recombinant MEK1, MKK4, IKKα, PKCα, Src, Syc and PDGFα at concentrations less than 30 μM. Also inhibits TGFβ-induced AP-1 activation in Mv1Lu cells (IC50 = 3.1 μM).

Used to block ERK signaling..
Assay Type: In Vitro
Species: Human

Pancreatic cancer cells were pretreated for 2 hours with FR 180204 followed by conventional chemotherapeutics. MEK inhibition had an additive effect on cancer cell’s viability upon 3 days of treatment.

FR 180204 blocks LPA induced COX-2 expression.

Cell Line/Tissue: Osteosarcoma

MG-63 cells were pre-incubated with 10 µM FR 180204 for 30 min followed by treatment with 10 µM LPA for 3 h to follow COX-2 expression using Western blot. FR 180204 inhibited COX-2 induction by LPA.
