名稱:異煙酰胺
 

純度:99% 包裝:25kg/桶
結構式
                

CAS:  1453-82-3
分子式:  C6H6N2O
分子量:  122.12

中文名稱:  異煙胺
                   異煙酰胺
                   4-吡啶甲酰胺

英文名稱:  isonicotinamide
                   4-carbamoylpyridine
                   4-pyridinecarboxamide

性質描述: 白色或類白色結晶性粉末,熔點  155-158 ,水溶性  191.7 g/L (37)

用途:  結構類似煙酰胺,進入細胞可起殺菌作用。在pH較低的條件下,抗菌活性較強,異煙酰胺為二線抗結核藥,與其它抗結核藥無交叉耐藥性,主要用于經一線藥物活療無效的病例。單用異煙酰胺易產生耐藥性需與其它抗結核藥物聯合應用。
