Paeonol is a phenolic compound reported for its various pharmacological activities such as antioxidant, anti‐inflammatory and antidiabetic activity. There are no systematic scientific reports on the in vivo toxicity of paeonol. So, the present work was designed to study in silico and in vivo toxicity of paeonol. In silico toxicity predictions were carried out using pkCSM, ProTox‐II, pre‐ADMET server and OSIRIS property explorer. Acute oral toxicity study of paeonol was carried out in female Sprague Dawley rats at a single dose of 300 mg/kg, 2000 mg/kg and 5000 mg/kg. Animals were observed for toxicity signs and mortality for 14 days. Repeated dose oral toxicity study of paeonol was carried out in female and male Sprague Dawley rats at a dose of 50, 100 and 200 mg/kg body weight for 28 days. At the end of the study, hematological, biochemical and urine parameters were assessed. Histopathology of vital organs was also carried out. In silico toxicity study predicted that paeonol is non‐toxic. The maximally tolerated dose of paeonol was found to be 5000 mg/kg in acute toxicity study in female rats. Paeonol was found to be safe at a dose of 50, 100 and 200 mg/kg in repeated dose toxicity study in male and female rats.

丹皮酚的计算机模拟和体内毒理学评价

丹皮酚是一种酚类化合物,具有多种药理活性,如抗氧化、抗炎和抗糖尿病活性。丹皮酚的体内毒性尚无系统的科学报告。因此,目前的工作旨在研究丹皮酚的计算机和体内毒性。使用 pkCSM、ProTox-II、pre-ADMET 服务器和 OSIRIS 属性浏览器进行了计算机毒性预测。在雌性 Sprague Dawley 大鼠中以 300 mg/kg、2000 mg/kg 和 5000 mg/kg 的单剂量进行了丹皮酚的急性口服毒性研究。观察动物的毒性迹象和死亡率 14 天。在雌性和雄性 Sprague Dawley 大鼠中以 50、100 和 200 mg/kg 体重的剂量进行了丹皮酚的重复剂量口服毒性研究,持续 28 天。在研究结束时,血液学、生化和尿液参数进行了评估。还进行了重要器官的组织病理学检查。计算机毒性研究预测丹皮酚是无毒的。在雌性大鼠的急性毒性研究中发现丹皮酚的最大耐受剂量为 5000 mg/kg。在雄性和雌性大鼠的重复剂量毒性研究中,发现丹皮酚在 50、100 和 200 mg/kg 的剂量下是安全的。
