Grp94 Inhibitor-1

Grp94 Inhibitor-1 is a potent, selective Grp94 inhibitor with an IC 50 value of 2 nM, and over 1000-fold selectivity to Grp94 against Hsp90α In Vitro Grp94-specific clients include a subset of integrin subunits such as integrin α2 and integrin αL. Their maturation and trafficking to the cell surface are dependent on the Grp94 chaperone function but have no association with cytoplasmic Hsp90α. Grp94 Inhibitor-1 (1-5 μM; 36 hours) significantly downregulated the cell surface expression levels of integrin α2 and integrin αL in a dose-dependent manner in panc1 cells. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Western Blot AnalysisCell Line: Panc1 cells Concentration: 1 μM; 2.5 μM; 5 μM Incubation Time: 36 hours Result: Decreased integrin α2 and integrin αL protein expression. In Vivo Grp94 Inhibitor-1 (intraperitoneal injection,qid.; coadminbistration 10 mg/kg or 30 mg/kg; 8 days) does not attenuate the colon shortening, but decreases disease activity index (DAI) scores. It also TNFα and IL-6 levels in the serum and colonic tissues and significantly reduces the p65 expression in colonic tissues, especially those in the 30 mg/kg dose group . MCE has not independently confirmed the accuracy of these methods. They are for reference only. Animal Model: C57BL/6 mice (male, 20-22 g) Dosage: 10 mg/kg or 30 mg/kg Administration: Intraperitoneal injection,qid.; coadminbistration 10 mg/kg or 30 mg/kg Result: Decreased disease activity index (DAI) scores in UC mices.
