Biological Activity
One week post-myocardial infarction (MI), MR 409 (MR-409) significantly reduces plasma levels of IL-2, IL-6, IL-10 and TNF-α compared to placebo[1].
MR 409 (MR-409; 1 μM) suppresses p53 expression in bovine pulmonary arterial endothelial cells (BPAECs)[2].
MR 409 (1 μM) induces the activation of JAK2, STAT3 and ERK1/2[2].
MR 409 (MR-409; 1 and 5 μM) decreases LPS-induced PGE2 and 8-iso-PGF2α levels, in a dose-dependent manner[3].
MR 409 (1 and 5μM) decreases LPS-induced lactate dehydrogenase (LDH) activity and nitrite production, without showing a dose-dependent effect[3].
MR 409 (1 and 5 μM) decreases LPS-induced gene expression of COX-2, NF-κB and iNOS in colon specimens, without a dose-dependent effect[3].
MR 409 (MR-409) can stimulate endogenous neurogenesis and improve the tMCAO-induced loss of neuroplasticity. MR 409 also enhances the proliferation and inhibits apoptosis of neural stem cells treated with oxygen and glucose deprivation-reperfusion[4].
