Actagardin is a tetracyclic antibiotic.
Actagardin is a tetracyclic antibiotic produced by several species of Actinoplanes.
In vitro: During the repeated fermentations of actagardin, two new compounds, named D and E, were isolated. Compound D was found to be twice as active as actagardin against Streptococcus pyogenes C 203 and four times more active than actagardin against Staphylococcus aureus ATCC 6538, S. pneumoniae UC 41, and S. aureus TOUR in the in-vitro tests [1].
In vivo: Animal study showed that compound D was also more effective than the parent compound actagardin against experimental infections in mice with either S. pyogenes C 203 or S. aureus TOUR, after sc administration. However, compound D was ineffective at doses up to 150 mg/kg when given orally to mice infected with S. pyogenes C 203. Moreover, compound D (LD50 1,250 mg/kg, mice, ip) was about 2.5 times more toxic than actagardine (3,310 mg/kg). In addition, compound E showed practically no in vitro activity up to 50 μg/ml against the tested organisms [1].
Clinical trial: So far, no clinical study has been conducted.

grace粉末来配制,按说明书上的话加入碳酸氢钠外就不用加入
别的东西了,请问是否可以直接过滤用了:
在问,我们同一楼的另外一个实验室配制的时候加入了
水解乳蛋白和酵母粉,是否有这个必要,谢谢.在线,急等
不过因为食品添加剂种类很多,适应范畴和添加量都是规定的,如果你未按gb2760的规定使用,可能构成违法,具体是否是犯罪,要看具体的性质。
比如:二氧化钛(就是食品级的钛白粉)允许在允许在膨化食品、果冷、凉果等类限量使用,如果你在肉制品中使用,属于超范围墙使用,就是违法行为。
其次是超量使用,一般超量使用,又没有构成严重后果,属滥用食品添加剂,一般不按犯罪处理。
但超范围使用,加上媒体炒作的话,可能就麻烦了,因为公-安-执-法部门对此不太专业,往往会有意无意的扩大化,有可能会按刑法143条,生产销售伪劣食品罪起诉。
要注意:食品添加剂和非法添加物的区别,食品添加剂是国家允许使用的物质,而非法添加剂则是指食品及添加剂以外的物质,如三聚氰胺、吊白块、苏丹红等,不是食品添加剂,如果使用此类物质,则构成犯罪。
