Mechanism of Action

Targets/IC₅₀/Ki	IRE1α (Cell-free) 0.6 μM
In vitro	In INS-1 cells, KIRA6 inhibits IRE1α auto-phosphorylation by Tg and XBP1 mRNA splicing by Tm in a dose-dependent manner.
In vivo	Intravitreally, KIRA6 preserves photoreceptor functional viability in rat models of ER stress-induced retinal degeneration. Systemically, KIRA6 preserves pancreatic β-cells, increases insulin, and reduces hyperglycemia in Akita diabetic mice. KIRA6 inhibits IRE1α in vivo to preserve cell viability and function in diverse cells and rodent tissues experiencing ER stress. The pharmacokinetic profile of KIRA6 in BALB/c mice intraperitoneally (i.p.) dosed at 10 mg/kg shows good drug plasma AUC levels (AUC 0-24h = 14.3 μM*h) with moderate clearance (22.4 mL/min/kg). Drug half-life is 3.90 hours, Cmax is 3.3 μM, and plasma levels at 4 and 8hr are 1.2 μM and 0.33 μM, respectively.
