title: Toxicological studies on a new macrolide antibiotic, midecamycin acetate (miocamycin). Part IV-7. Toxicity of metabolites of miocamycin: acute toxicity of Mb6 in mice.
abstract: Miocamycin (MOM) is a derivative of midecamycin and is metabolized into 4 main metabolites. In the present studies, we evaluated acute toxicity and estimated LD50 values of Mb6, one of the main metabolites of MOM, in male and female mice after single oral administration. Observations were continued for 1 week after treatment. The LD50 values were calculated according to Litchfield-Wilcoxon's method. It is concluded that LD50 values of Mb6 were 4,150 mg/kg (3,577.6 approximately 4,814.0 mg/kg) in male mice and 4,000 mg/kg (3,389.8 approximately 4,720.0 mg/kg) in female mice, respectively.
