Kira8 生物活性

描述 IRE1 (inositol requiring enzyme 1) is an ER transmembrane sensor that activates UPR to maintain ER and cellular function. It can promotes cell survive and initiate apoptosis via decay of anti-apoptotic microRNAs[1]. KIRA8 is an ATP-competitive, potent and selective IRE1α kinase inhibitor (IRE1α/β Ki = 2/120 nM) that attenuates IRE1α endonuclease activity (IRE1α/β IC50 = 5/55 nM) with good kinome selectivity[2]. Kira8 blocks IRE1α oligomerization, and potently inhibits IRE1α RNase activity against XBP1 and Ins2 RNAs. Kira8 more potently reduces IRE1α-driven apoptosis in INS-1 cells than KIRA6 and also reverses XBP1 splicing promoted by GNF-2. Male Ins2+/Akita mice are injected i.p. with KIRA8 (50 mg/kg; daily; for 35 days), significant reduction of hyperglycemia become apparent over several weeks. One week treatment of pre-diabetic NODs mice with Kira8 (50 mg/kg; i.p.; once a day) leads to significant reductions in islet XBP1 splicing and TXNIP mRNAs, and preserves Ins1/Ins2, BiP and MANF mRNAs [3].
