制备方法与用途

生物活性

Dixyrazine 是一种 Phenothiazine 衍生物，能预防注射硫酸鱼精蛋白引起的脑水肿。

体内研究

Pretreatment with Dixyrazine (10 mg/kg) 完全防止了脑水肿，并显著减少了 cerebrospinal fluid (CSF) 中的血清白蛋白增加。静脉注射 Dixyrazine（5 mg/kg）这种苯硫氮卓衍生物具有轻微且短暂的降压作用，但在清醒大鼠中，它能显著减少由静脉注射去甲肾上腺素或bicuculline 引起的急性高血压时，标记有 (^{126})I 的血清白蛋白泄漏。在麻醉大鼠中，通过闭合颅骨窗口使用多通道视频血管成像仪连续测量皮层动脉和静脉直径，在静脉注射 Dixyrazine（5 mg/kg）前后进行。

Dixyrazine（5 mg/kg）诱导轻微但短暂的血压下降（10-20 mmHg），Dixyrazine 处理组的最大平均动脉压略有降低，但无显著性差异。
