| Hazard Information | Back Directory | [Uses]
Begacestat (GSI-953) is a selective β-secretase inhibitor that selectively inhibits cleavage of APP over Notch. GSI-953 is used for treating diseases such as cancer in relation to prevention of intestinal secretory metaplasia. | [Biological Activity]
Begacest at (GSI-953) is a selective γ-secretase inhibitor th at selectively inhibits cleavage of APP over Notch. | [in vivo]
Begacestat (5 mg/kg, p.o. in mice) treatment for 4 h significantly reduces the Aβ40 and Aβ42 in brain (37% lowering of brain Aβ40 and 25% lowering of Aβ40 observed)[1].
Begacestat (GSI-953: 0, 2.5, 5, or 10 mg/kg, oral gavage, 3 h) results in a dose-dependent reversal of contextual fear conditioning deficits when compound is orally administered 3 h before training. Significant deficits are observed after treatment with 2.5 mg/kg Begacestat, and there is some reversal of this at 5 mg/kg and full reversal at 10 mg/kg compared with vehicle-dosed Tg2576 mice[2].
A dosage-related trend of slightly lower percentages of SP CD4+ cells in males at all dosages (SP CD4+ cells=~11% in controls compared with ~7% to ~9% in Begacestat-dosed animals) and females at 2000 mg/kg/day (SP CD4+ cells=~10% in controls compared with ~8% in Begacestat-dosed animals) is observed[2]. | Animal Model: | Tg2576 mice[2] | | Dosage: | 0, 2.5, 5, or 10 mg/kg | | Administration: | Oral gavage for two consecutive days | | Result: | Resulted in a dose-dependent reversal of contextual fear conditioning deficits when compound is orally administered 3 h before training. |
| Animal Model: | Sprague-Dawley rats[2] | | Dosage: | 0, 200, 600, or 2000 mg/kg/day for 10 (5 males/group and 5 females at 600 mg/kg/day) or 28 (10/sex/group) consecutive days | | Administration: | P.O. for 10 (5 males/group and 5 females at 600 mg/kg/day) or 28 (10/sex/group) consecutive days. | | Result: | A dosage-related trend of slightly lower percentages of SP CD4+ cells in males at all dosages and females at 2000 mg/kg/day was observed. |
