Description

KIRA6 is an advanced small-molecule IRE1α RNase kinase inhibitor with an IC50 of 0.6 µM[2]. KIRA6 can trigger an apoptotic response[1].

IC50 & Target

IC50: 0.6 µM (IRE1α RNase kinase)[2]
In Vitro

KIRA6 (1nM-100μM) bounds to the cytoplasmic domain of KIT with a Kd value of 10.8  µM[1].
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[1].
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[1].
KIRA6 (1 μM; 0-48 hours) inhibits Ins1 mRNA decay from IRE1α hyperactivation at a dose-dependent manner[2].
KIRA6 (0.1-10μM; 72 hours) dose-dependently reduces 1NM-PP1 potentiation of Ins1 apoptosis during ER stress in a dose-dependent manner[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Viability Assay[1]

Cell Line: HMC-1.1 cells
Concentration: 10 nM, 30 nM, 100 nM, 300 nM, 1000 nM
Incubation Time: 72 hours
Result: Inhibited cell viability from 30 nM.

Western Blot Analysis[1]

Cell Line: HMC-1.1 cells
Concentration: 10 nM, 30 nM, 100 nM, 300 nM, 1000 nM
Incubation Time: 1 hours
Result: Reduced expression of phosphorylated KIT, STAT5 and ERK1/2.

RT-PCR[2]

Cell Line: INS-1 IRE1α (WT) cells
Concentration: 1 μM
Incubation Time: 0 hour, 12 hours, 24 hours, 48 hours
Result: Inhibited Ins1 mRNA expression.

Apoptosis Analysis[2]

Cell Line: INS-1 IRE1α (WT) cells
Concentration: 1-10 μM
Incubation Time: 72 hours
Result: Reduced 1NM-PP1 potentiation of Ins1 apoptosis during ER stress.
In Vivo

KIRA6 (intraperitoneal injection; 5 mg/kg; 37 days) shows significant amelioration of random glucose levels over several weeks compared to vehicle, both fed ad lib[2].
KIRA6 (intraperitoneal injection; 5 mg/kg; 21 or 18 days postinjections) increases both plasma insulin and C-peptide levels, remains insulin-positive islet areas at high level after stopping injections in the Akita Mouse[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Male Ins2+/Akita mice[2]
Dosage: 5 mg/kg
Administration: Intraperitoneal injection; 5 mg/kg; 21 or 18 days postinjections
Result: Attenuates b cell functional loss, increased insulin levels.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
