产品描述：
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.
