BI-D1870 | CAS#501437-28-1 | RSK inhibitor

MedKoo Cat#: 500405 | Name: BI-D1870

Description:

WARNING: This product is for research use only, not for human or veterinary use.

BI-D1870 is a potent and specific RSK inhibitor (the p90 ribosomal S6 kinase), which inhibits RSK1, RSK2, RSK3 and RSK4 in vitro with an IC50 of 10Â–30 nM. BI-D1870 exhibited a dose-responsive antiproliferative effect on OSCC cells with relative sparing of normal human oral keratinocytes. The compound inhibited the downstream RSK target YB-1 and caused apoptosis. In addition, BI-D1870 also induced G2/M arrest by modulating the expression of p21 and other cell cycle regulators. BI-D1870 may be of useful in oral squamous cell carcinoma therapy.

Biological target:

BI-D1870 is a cell permeable and brain penetrated inhibitor of RSK isoforms, with IC50s of 31 nM/24 nM/18 nM/15 nM for RSK1/RSK2/RSK3/RSK4, respectively.

In vitro activity:

BI-D1870 inhibited cellular viability in a dose-dependent manner with IC50 of 1.62, 1.91, and 2.52 μM for MOLM-13, MV-4-11, and HL60 cell lines, respectively (Supplementary Figure 2A), while normal human hematopoietic cells demonstrated no significant decrease in colony formation for up to 10 μM of BI-D1870 (Supplementary Figure 2B).
