KIRA6 is an advanced small-molecule IRE1α RNase kinase inhibitor with an IC50 of 0.6 µM. KIRA6 can trigger an apoptotic response.
IC50&Target
IC50: 0.6 µM (IRE1α RNase kinase)
体外研究
KIRA6 (1nM-100μM) bounds to the cytoplasmic domain of KIT with a Kd value of 10.8 µM.
KIRA6 (10-1000 nM; 72 hours) strongly compromises the viability of the KIT-dependent cell line HMC-1.1 at the low nM concentration, in a manner that coincided with KIT blockade.
KIRA6 (10-1000 nM; 1 hour) reduces signaling output of KIT, including the phosphorylation of KIT as well as its downstream signaling modules, PSTAT5 and phosphorylated ERK1/2.
KIRA6 (1 μM; 0-48 hours) inhibits Ins1 mRNA decay from IRE1α hyperactivation at a dose-dependent manner.
KIRA6 (0.1-10μM; 72 hours) dose-dependently reduces 1NM-PP1 potentiation of Ins1 apoptosis during ER stress in a dose-dependent manner.
