| Bioactivity | Etazolate hydrochloride (SQ 20009) is an orally active, selective inhibitor of type 4 phosphodiesterase (PDE4) with an IC50 of 2 μM. Etazolate hydrochloride is a γ-aminobutyric acid A (GABAA) receptor regulator. Etazolate hydrochloride is an α-secretase activator and induced the production of soluble amyloid precursor protein (sAPPα). Etazolate hydrochloride, a pyrazolopyridine class derivative, increases cAMP levels. Etazolate hydrochloride has anxiolyticlike, antidepressant-like and anti-inflammatory effects[1][2][3][4][5]. |
| Invitro | Etazolate hydrochloride (SQ 20009; 25 µM) 在 LtT7.TR 细胞中显着增加精氨酸酶和 ODC 蛋白质水平的表达(精氨酸酶和 ODC 分别为~3.1 倍和~1.6 倍) [2]。 |
| In Vivo | Etazolate hydrochloride (SQ 20009; 1, 3, 10 mg/kg; 腹腔给药) 在小鼠创伤性脑损伤 (TBI) 后持续改善识别记忆并减少运动过度活跃[3]。 Etazolate hydrochloride (0.5, 1 mg/kg; 灌胃给药; 每天一次; 21 天) 在瑞士白化小鼠 (22-25 g)中显着抑制慢性不可预知的轻度应激 (CUMS) 诱导的行为 (减少蔗糖消耗并增加不动的持续时间) 和生化 (增加脂质过氧化和亚硝酸盐水平;降低谷胱甘肽、超氧化物歧化酶和过氧化氢酶活性) 的变化[4]。 Etazolate hydrochloride (0.5, 1 mg/kg; 腹腔注射; 单次) 在雄性 Wistar 大鼠 (250-275 g) 中拮抗 Reserpine (HY-N0480; 1 mg/kg;腹腔注射) 诱导的体温过低[5]。 Animal Model: |
