Biological Activity

[Description]:

Antalarmin is a selective nonpeptide corticotropin-releasing factor receptor 1 (CRHR1) antagonist with a Ki of 2.7 nM. Antalarmin can pass through the blood–brain barrier[1][2][3].

[In Vitro]

Antalarmin 通过 cAMP/PKA 信号通路抑制促肾上腺皮质激素释放因子 (CRF) 对 Aβ1-42 水平的影响[2]。 Western Blot Analysis[2] Cell Line: Primary hippocampal neurons derived from Tg2576 mice Concentration: 100 nM Incubation Time: 48 h Result: Blocked CRF-induced increases in PKAIIβ levels.

[In Vivo]

Antalarmin (10 mg/kg; i.p.; daily for 4 weeks) 可以改善小鼠的慢性轻度应激 (CMS) 诱导的变化[1]。 Antalarmin (20 mg/kg; i.p.; daily for 7 days) 显著降低亚急性应激 Tg2576 小鼠中 Aβ1-42 水平[2]。 Animal Model: BALB/cByJIco male mice, chronic mild stress model[1] Dosage: 10 mg/kg Administration: Intraperitoneal injection, daily for 4 weeks Result: Induced a significant improvement of mice physical state. Induced a nonsignificant decrease of the lit box (TLB) and activity when compared to controls.
