用途: EHT 1864 is a small molecule inhibitor of Rac1 signaling; modulate γ-Secretase-mediated APP processing.IC50 value:Target: Rac1 inhibitorin vitro: EHT 1864 blocks Aβ 40 and Aβ 42 production but does not impact sAPPα levels and does not inhibit γ-secretase. Rather, EHT 1864 modulates APP processing at the level of γ-secretase to prevent Aβ40 and Aβ42 generation. This effect does not result from a direct inhibition of the γ-secretase activity and is specific for APP cleavage, since EHT 1864 does not affect Notch cleavage [1]. EHT 1864 specifically inhibited Rac1-dependent platelet-derived growth factor-induced lamellipodia formation. Furthermore, our biochemical analyses with recombinant Rac proteins found that EHT 1864 possesses high affinity binding to Rac1, as well as the related Rac1b, Rac2, and Rac3 isoforms, and this association promoted the loss of bound nucleotide, inhibiting both guanine nucleotide association and Tiam1 Rac guanine nucleotide exchange factor-stimulated exchange factor activity in vitro [2].in vivo: EHT1864 significantly reduces Aβ 40 and Aβ 42 levels in guinea pig brains at a threshold that is compatible with delaying plaque accumulation and/or clearing the existing plaque in brain [1]. 作用: EHT 1864是Rac1信号传导的小分子抑制剂;调节γ-分泌酶介导的APP加工。 体外Rac1抑制剂:EHT1864阻断Aβ40和Aβ42的产生但不影响sAPPα水平并且不抑制γ-分泌酶。相反,EHT 1864调节γ-分泌酶水平的APP加工以防止Aβ40和Aβ42的产生。这种效应不是由γ-分泌酶活性的直接抑制引起的,并且对APP裂解是特异性的,因为EHT 1864不影响Notch裂解。 EHT 1864特异性抑制Rac1依赖性血小板衍生生长因子诱导的片状伪足形成。此外,我们用重组Rac蛋白进行的生化分析发现EHT 1864具有高亲和力结合Rac1,以及相关的Rac1b,Rac2和Rac3同种型,这种关联促进结合核苷酸的缺失,抑制鸟嘌呤核苷酸结合和Tiam1 Rac鸟嘌呤核苷酸交换因子刺激体外交换因子活性。体内:EHT1864显着降低豚鼠脑中的Aβ40和Aβ42水平,其阈值与延迟斑块积聚和/或清除脑中现有斑块相容。 物理化学性质: CAS号:754240-09-0 常用中文名:EHT 1864 常用英文名:EHT 1864 分子式:C25H29Cl2F3N2O4S 分子量:581.475 密度:N/A 沸点:N/A 熔点:N/A 闪点:N/A 储存条件:2-8°C |
