制备方法与用途

生物活性

Tazanolast 是一种选择性的肥大细胞稳定药物。体外研究显示,它能够抑制被动皮肤过敏反应、隔离的支气管平滑肌 Schutz-Dale 反应和实验性哮喘,而不会对抗组胺白三烯 D4 引起的收缩、IgE 介导或化合物 48/80 引起的组胺释放、肺片中化合物 48/80 引起的细胞外介质中的钙离子摄取、化合物 48/80 引起的蛋白激酶 C 膜转运以及磷酸肌醇三磷酸生成,而不直接抑制组胺引起的磷脂酶 C 活性。

体内研究

在暴露于臭氧前给予 Tazanolast (30, 100 或 300 mg/kg) 可以剂量依赖地抑制臭氧诱导的气道高反应性。而在暴露后给予 Tazanolast 并不能抑制气道高反应性。Tazanolast 在暴露后2小时并不会显著改变支气管肺泡灌洗 (BAL) 细胞的分布,并且能够显著抑制臭氧诱导的气道高反应性。

化学性质

他扎司特为白色或微带黄色结晶性粉末,略具气味,味苦。易溶于丙酮,较易溶于甲醇乙醇乙腈,难溶于乙醚,几乎不溶于。急性毒性实验显示:雄性小鼠、雌性小鼠、雄性大鼠和雌性大鼠口服 LD50 大于 4000 mg/kg;皮下注射大于 4000 mg/kg;腹腔注射分别为 1145、1191、1423 和 1528 mg/kg;静脉注射分别为 1126、1121、1119 和 1277 mg/kg。

用途

主要用于治疗支气管哮喘。

生产方法

在冰浴条件下,将草酸单丁酯单酰在30分钟内滴加到5-(3-氨基苯基)四唑吡啶溶液中,可得到他扎司特

    Hydroxylated nebivolol metabolites increase NO release from human endothelial cell preparations in a concentration dependent fashion following acute administration. In addition, hydroxylated nebivolol metabolites, including but not limited to 4-hydroxy-6,6′difluoro-, 4-hydroxy-5-phenol-6,6′difluoro-, and 4-hydroxy-8-pheno-6,6′difluoro-, have the ability to increase the capacity for NO release in human endothelial cells following chronic administration. This invention provides hydroxylated nebivolol metabolites and compositions comprising nebivolol and/or at least one hydroxylated metabolite of nebivolol and/or at least one additional compound used to treat cardiovascular diseases or a pharmaceutically acceptable salt thereof. In addition, this invention provides methods of treating and/or preventing vascular diseases by administering at least one hydroxylated metabolite of nebivolol that is capable of releasing a therapeutically effective amount of nitric oxide to a targeted site affected by the vascular disease. Also, this invention is directed to the treatment and/or prevention of migraine headaches administering at least one hydroxylated metabolite of nebivolol. This invention may also be used in conjunction with or as a single treatment of metabolic syndrome disorders.
