美芬妥因制备

【方法一】
由苯丙酮环合、甲基化而得。1.环合将碳酸铵、氰化钾、氨水依次加入苯丙酮和乙醇的混合液中，加热反应后，将反应物放入冰水中，加稀盐酸至pH为5-6，析了白色粉末。过滤，滤液加硫酸亚铁水溶液破坏氰化物。滤饼用水洗至中性，干燥，得5-乙基-5-苯基乙内酰脲。2.甲基化将5-乙基-5-苯基乙内酰脲溶于氢氧化钠溶液中，缓缓加入硫酸二甲酯，在12-15℃反应2h至反应液为中性。过滤，滤饼先后用10%氢氧化钠溶液和水洗涤，干燥得美芬妥英粗品。精制而得成品。

Cheminformatics analysis of assertions mined from literature that describe drug-induced liver injury in different species.

Chem. Res. Toxicol. 23 , 171-83, (2010)

Drug-induced liver injury is one of the main causes of drug attrition. The ability to predict the liver effects of drug candidates from their chemical structures is critical to help guide experimental...

J. Sci. Ind. Res. 65(10) , 808, (2006)

Drug-induced liver injury (DILI) is a significant concern in drug development due to the poor concordance between preclinical and clinical findings of liver toxicity. We hypothesized that the DILI typ...
