1346546-69-7 Usage

Description

GSK 872 (CAS 1346546-69-7) is a potent (IC50 = 1.8nM domain binding; IC50 = 1.3 nM kinase activity) and selective inhibitor of receptor interacting protein 3 (RIP3).1 It is able to prevent necroptosis, virus-induced necrosis, and TLR3-induced necrosis.1,2 GSK872 can induce Caspase8-mediated apoptosis at higher concentrations (e.g.3 μM).2

Uses

GSK''872 is a potent and selective receptor activating protein kinase 3 (RIP3) inhibitor (IC50 = 1.3 nM). Exhibits >1000-fold selectivity for RIP3 over a panel of 300 other kinases including RIP1. Inhibits TNF-induced cell death in 3T3-SA cells and TLR3-induced necrosis in fibroblasts in vitro. Blocks necroptosis of primary human neutrophils from whole blood. Also induces apoptosis at higher concentrations (3 - 10 μM).

Biological Activity

GSK'872 (GSK2399872A) is a potent and selective RIP3 kinase inhibitor which binds RIP3 kinase domain with high affinity (IC50=1.8 nM) and inhibits kinase activity with IC50 of 1.3 nM. It has minimal cross-reactivity.

in vitro

When assayed at 1 μM, GSK'872 fails to inhibit most of 300 human protein kinases tested. It fails to inhibit RIP1 kinase when tested directly. GSK'872 blocks TNF-induced necroptosis in a concentration-dependent manner in HT-29 cells. In cell-based assays, there is a 100- to 1000-fold shift in the IC50 compared to the cell-free biochemical assays. GSK'872 also blocks necroptosis in primary human neutrophils isolated from whole blood. GSK'872 inhibits TLR3- or DAI-induced death, two RIP1-independent pathways of necroptosis. It induces caspase activation followed by apoptotic cell death.

in vivo

GSK'872 treatment significantly decreases HIF-1α expression compared with no treatment after ischemia injury in vivo.

Check Digit Verification of cas no

The CAS Registry Mumber 1346546-69-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,6,5,4 and 6 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1346546-69:
(9*1)+(8*3)+(7*4)+(6*6)+(5*5)+(4*4)+(3*6)+(2*6)+(1*9)=177
177 % 10 = 7
So 1346546-69-7 is a valid CAS Registry Number.
