The antimalarial activity and lipid profiles of Methyl Jasmonate (MJ) were investigated against established malaria infection in vivo using BALB/c mice.
Arteether (AE) and chloroquine (CQ) were used as reference drugs while ethanol was used as the vehicle for drug delivery for MJ.
Mice treated with 10 and 25 mg/kg MJ showed a remarkable reduction in percentage parasitemia by 68.3% and 78.2% on day 10(post treatment) respectively while 45.4% and 87.2% reduction in percentage parasitemia were observed in the group treated with 50 mg/kg on day 3 and 10 (post treatment) respectively. The highest mean survival time was observed in CQ followed by AE and MJ in dose-dependent manner. A progressive decrease in packed cell volume (PCV) was observed in infected untreated mice which led to the death of all the mice by day 9 (post treatment). Infected mice treated with MJ showed reduced level of HDL and LDL compared with infected untreated group. As the dose of MJ increased in infected mice cholesterol levels increased while there was reduction in triglyceride.
Overall there was marked decrease in parasitemia in Plasmodium berghei infected mice treated with graded doses of MJ but appears to have reduced antimalarial activity compared with CQ and AE.
使用BALB/c小鼠,对茉莉酸甲酯(MJ)在体内针对已建立的疟疾感染的抗疟活性和脂质谱进行了研究。
蒿乙醚(AE)和氯喹(CQ)用作参考药物,而乙醇用作MJ给药的载体。
用10和25mg/kg MJ处理的小鼠在第10天(治疗后)分别显示疟原虫血症百分比显著降低68.3%和78.2%,而在第3天和第10天(治疗后)用50mg/kg处理的组中观察到疟原虫血症百分比分别降低45.4%和87.2%。观察到CQ组的平均生存时间最长,其次是AE组和MJ组,呈剂量依赖性。在未治疗的感染小鼠中观察到红细胞压积(PCV)逐渐下降,导致所有小鼠在第9天(治疗后)死亡。与未治疗的感染组相比,用MJ治疗的感染小鼠的高密度脂蛋白(HDL)和低密度脂蛋白(LDL)水平降低。随着感染小鼠中MJ剂量的增加,胆固醇水平升高,而甘油三酯水平降低。
总体而言,用分级剂量的MJ治疗的伯氏疟原虫感染小鼠的疟原虫血症显著降低,但与CQ和AE相比,似乎抗疟活性降低。
