[体外研究]

Bromisoval(BU)抑制一氧化氮(NO)释放和促炎细胞因子在脂多糖(LPS)-β2细胞(一种小鼠小胶质细胞系)中的表达。 Bromisoval抑制LPS诱导的信号转导和转录激活因子1(STAT1)的磷酸化和干扰素调节因子1(IRF1)的表达。 Janus激酶1(JAK1)抑制剂filgotinib比Bromisoval抑制NO释放更弱,尽管filgotinib几乎完全阻止LPS诱导STAT1磷酸化。敲除JAK1,STAT1或IRF1不会影响Bromisoval对LPS诱导NO的抑制作用。 Bromisoval和filgotinib的组合协同抑制NO释放。线粒体复合物I抑制剂鱼藤酮,其不阻止STAT1磷酸化或IRF1表达,抑制促炎介质表达不如Bromisoval显着。 Bromisoval和鱼藤酮以相似的程度降低细胞内ATP(iATP)水平。鱼藤酮和filgotinib的组合抑制LPS处理的BV2细胞中的NO释放与Bromisoval一样强[1]。

[体内研究]

Bromisoval(Bromvaletone)和carbromal是每个系列中最有效的中枢抑制剂。腹腔注射Bromisoval后雄性小鼠的抑郁活性(ISD50值)和急性毒性(LD50值)分别为0.35(0.30-0.39)和3.25(2.89-3.62)mmol/kg [2]。

[激酶实验]

从BV2细胞培养物获得调理培养基，所述BV2细胞培养物已经在含有1μg/ ml LPS，含有或不含有Bromisoval（BU）（1-100μg/ mL）或其他试剂的E2培养基中孵育24小时，并进行NO测定。为了通过细胞蛋白质含量使释放的NO水平正常化，用RIPA缓冲液（50mM Tris-HCl，pH 8.0,150mM氯化钠，0.5％w / v脱氧胆酸钠，0.1％w / v十二烷基硫酸钠， 1.0％w / v NP-40替代品）和蛋白质含量由BCA蛋白质测定试剂测定[1]。

[细胞实验]

使用鼠小胶质细胞系BV2。将BV2细胞维持在补充有10％胎牛血清的培养基中。将BV2细胞接种在4孔培养板中的孔上，并与LPS孵育30分钟至24小时。当研究Bromisoval（BU）或其他药物的作用时，将BV2细胞与适当的药剂（例如Bromisoval）一起孵育30分钟，然后加入LPS [1]。

[动物实验]

将化合物（包括Bromisoval）在0.5％羧甲基纤维素水溶液中的悬浮液腹膜内给予体重25-35g的成年雄性白化小鼠。所有测试均在10只小鼠的组中进行[2]。
