|Description||kira6 is a potent type II IRE1α kinase inhibitor with an IC50 of 0.6 μM. It dose-dependently inhibits IRE1α(WT) kinase activity, XBP1 RNA cleavage, Ins2 RNA cleavage and oligomerization.|
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.|

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
