STF-083010是Ire1α新型小分子抑制剂,可抑制Ire1核酸内切酶活性但不影响其激酶活性。
STF 083010 is a specific IRE1α endonuclease inhibitor. STF 083010 inhibits IRE1 endonuclease activity specifically through endogenous XBP1 mRNA splicing. STF 083010 has been shown to induce cytotoxic and cytostatic effects in CD138+ multiple myeloma (MM) cells in vitro in addition to inhibiting bortezomib-induced XBP1 activity in myeloma xenografts in vivo. STF 083010 shows no effect against IRE1 kinase activity. Inhibitor of IRE1α endonuclease activity; blocks endogenous XBP1 mRNA splicing. Displays cytostatic and cytotoxic effects in CD138+ multiple myeloma (MM) cells in vitro; inhibits bortezomib-induced XBP1 activity in myeloma xenografts in vivo. Does not alter IRE1α kinase activity.

动物 A (mg/kg) = 动物 B (mg/kg)×动物 B的Km系数/动物 A的Km系数 | |
例如,已知某工具药用于小鼠的剂量为88 mg/kg , 则用于大鼠的剂量换算方法:将88 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到该药物用于大鼠的等效剂量44 mg/kg。
