BI-D1870 是ATP 竞争性的,细胞可渗透性的、能透过血脑屏障的RSK抑制剂,抑制 RSK1、RSK2、RSK3、RSK4 的IC50值分别为 31 nM、24 nM、18 nM、15 nM。
生物活性 | BI-D1870 is an ATP-competitive, cell permeable and brain penetrated inhibitor ofRSKisoforms, withIC50s of 31 nM/24 nM/18 nM/15 nM for RSK1/RSK2/RSK3/RSK4, respectively[1][2][3][4][5]. |
IC50& Target | IC50: 31 nM (RSK1), 24 nM (RSK2), 18 nM (RSK3), 15 nM (RSK4)[1] |
体外研究 (In Vitro) | BI-D1870 inhibits a mutant of RSK2 lacking the C-terminal kinase catalytic domain (RSK21-389:S381E) with an IC50of approx. 30 nM. BI-D1870 inhibits RSK1 and RSK2 with IC50values of 10 nM and 20 nM respectively, when the kinase assays are performed with 100 μM ATP. When the assays are performed at a 10-fold lower ATP concentration, the IC50of BI-D1870 is reduced to 5 nM for RSK1 and 10 nM for RSK2[1]. BI-D1870 inhibits PLK1 with an IC50of 100 nM, whilst the IC50values for Aurora B, DYRK1a, CDK2-A, Lck, CK1 and GSK3β are 10- to 100-fold higher than that of the RSK isoforms. BI-D1870 (10 μM) inhibits the PMA-induced phosphorylation of GSK3α and GSK3β in HEK-293 cells. In HEK-293 cells, BI-D1870 inhibits the EGF-induced phosphorylation of LKB1 at Ser431 with an IC50of approx. 1 μM[1]. BI-D1870 does not affect the activation of ERK1/ERK2 and MSK1, nor does it inhibit the phosphorylation of CREB[1]. BI-D1870 is a potent RSK family kinase inhibitor (Kds: 10-100 nM), and also interact with BRD4(1) and PLK family, with Kds of 3.5 μM and appr 10 nM[2]. BI-D1870 (10 μM) strongly induces p70S6K activation in serum-starved LN-229 cells, and alao stimulates the phosphorylation of rpS6 and p70S6K in LN-18 cells. BI-D1870 (1 μM) potently inhibits rpS6 phosphorylation, and inhibits PMA-induced rpS6 phosphorylation at concentrations higher than 1 μM[4]. BI-D1870 (1-5 μM) induces a dose- and time-dependent inhibition of cell proliferation in all cell types. BI-D1870 (1-3 μM) induces apoptosis in SCC4 cells and HSC-3 cells. BI-D1870 (0-5) modulates cell survival signaling pathways including Akt and p38 MAPK dose-dependently[5].

体内研究 (In Vivo) | BI-D1870 (0.5 mg/kg)-injected experimental autoimmune encephalomyelitis (EAE) mice exhibits a delayed neural deficit without obvious weight loss. Histopathological analyses shows inflammatory cell infiltration and demyelination in the spinal cord in control mice, but not in BI-D1870-treated mice. BI-D1870 protects against the infiltration of TH1 or TH17 cells into the CNS[3].
