Benznidazole 生物活性

描述 Benznidazole is recommended for treatment of Chagas infection. Benznidazole monotherapy is superior to posaconazole, with high RT-PCR (real time polymerase chain reaction) conversion rates sustained at 1 year. Side effects lead to therapy discontinuation in 32%. No advantages were observed with combined therapy versus benznidazole monotherapy[3]. Benznidazole shows high bioavailability after oral administration. Benznidazole at 5 - 8 mg/kg/day and 5 - 10 mg/kg/day for 30 - 60 days are consistent clinical recommendations for children and adults, respectively[4]. The trypanocidal activity of vitamin C and benznidazole was similar for the three parasite forms. Animals treated with benznidazole presented lower parasitemia levels, as compared with those treated with vitamin C alone. Again, vitamin C did not cause any effect on the antiparasitic profile of benznidazole. The combination of vitamin C with benznidazole could be considered as an alternative treatment for Chagas' disease[5]. Patients previously treated with benznidazole had significantly reduced parasitemia, a lower prevalence of markers of severe cardiomyopathy, and lower mortality after two years of follow-up. If used in the early phases, benznidazole treatment may improve clinical and parasitological outcomes in patients with chronic ChD (chronic Chagas disease)[6].

溶解方案

DMSO: 50 mg/mL(192.12 mM),配合低频超声助溶,注意:DMSO长时间开封后,会吸水并导致溶解能力下降,请避免使用长期开封的DMSO

请根据您的动物给药指南选择适当的溶解方案。
以下溶解方案都请先按照体外实验的方式配制澄清的储备液,再依次添加助溶剂:
——为保证实验结果的可靠性,澄清的储备液可以根据储存条件,适当保存;体内实验的工作液,建议现用现配,当天使用; 以下溶剂前显示的百分比是指该溶剂在终溶液中的体积占比;如在配制过程中出现沉淀、析出现象,可以通过加热和/或超声的方式助溶
