Summary
IC50 & Target
IC50: 35.0 nM (RIPK1); EC50: 10.0 nM (HT29 cells), 4.2 nM (L929 cells), 11.4 nM (J774A.1 cells), 17.8 nM (U937 cells) [1] .
In Vitro
RI-962 has potent inhibitory activity for RIPK1 with an IC
50
value of 35.0 nM
[1]
.
RI-962 has protective effect for necroptotic death with EC
50
values of 10.0 nM, 4.2 nM, 11.4 nM, and 17.8 nM for HT29, L929, J774A.1, and U937 cells, respectively
[1]
.
RI-962 (0-100 μM; 24 h) protectes cells from TSZ-induced necroptosis by inhibiting the kinase activity of RIPK1
[1]
.
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
Cell Viability Assay [1]
| Cell Line: | HT29, L929, J774A.1, and U937 cells |
| Concentration: | 0-100 μM |
| Incubation Time: | 24 h |
| Result: | Exerted a dose-dependent protective effect against necroptotic death. |
Western Blot Analysis [1]
| Cell Line: | HT29 cells |
| Concentration: | 0-400 nM |
| Incubation Time: | |
| Result: | Markedly inhibited the phosphorylation of RIPK1 and its downstream signaling proteins RIPK3 and MLKL in a dose-dependent manner. |
In Vivo
RI-962 (i.p.; 40 mg/kg; once a day for 10 day) ameliorates TNFα-induced SIRS and reduces inflammation in acute DSS-induced colitis
