  Apoptosis[1]

• 体外研究: Osajin以剂量依赖性方式显着降低人NPC细胞(TW076,CG1和TW04细胞)的活力。 Osajin通过多种凋亡途径诱导人NPC细胞凋亡,包括外在死亡受体途径,以及依赖线粒体和内质网应激的内在途径[1]。 Osajin对六种人类癌细胞系具有生长抑制活性,包括肾,肺,前列腺,乳腺癌,黑色素瘤和结肠癌细胞[2]。
• 体内研究: Osajin和pomiferin可减轻缺血再灌注引起的心肌功能障碍。抗氧化酶值和总抗氧化活性的增加证实了这一点。 osajin和pomiferin治疗提供的心脏保护作用来自抑制氧化应激,这与改善的心室功能相关[3]。
• 细胞实验: 将NPC细胞接种在96孔板（5000个/孔）中并使其粘附24小时。然后用含有不同浓度（0.01-10μM）osajin的新鲜培养基替换培养基另外24小时。对于时程测定，5μMosajin的孵育时间为6,12,24,36和48小时。温育后，向每个孔中加入10μl5mg/ ml的MTT，并在37℃下孵育4小时。使用基于MTT的测定确定细胞活力[1]。
• 动物实验: 大鼠[1] Wistar大鼠分为四组。第一个治疗组接受osajin（5％/ kg /天，0.5％Avicel）;第二治疗组接受pomiferin（0.5 mg Avicel中5 mg / kg /天）;安慰剂组仅获得0.5 Avicel;最后一个是未经治疗的对照组。评价氧化损伤的生化指标 - 脂质过氧化产物丙二醛，抗氧化酶 - 超氧化物歧化酶，谷胱甘肽过氧化物酶，血清和心肌中的总抗氧化活性。研究了osajin和pomiferin对心功能，左心室舒张末压，左心室压力和峰值阳性+ dP / dt缺血再灌注的影响[1]。
