pubmed-article:6334171 | pubmed:abstractText | Miocamycin (MOM) is a derivative of midecamycin, a macrolide antibiotic isolated from a culture broth of Streptomyces mycarofaciens. MOM is metabolized into 4 main metabolites of Mb1, Mb2, Mb6 and Mb12. The object of this study was to evaluate acute toxicity in male and female mice after single oral administration of Mb1, a metabolite of MOM, at a dose level of 5,000 mg/kg as the maximum physically applicable dose. Observations were kept for 1 week after administration. In conclusion, Mb1 exhibited no acute toxicity in present study. The LD0 values were estimated as more than 5,000 mg/kg. | lld:pubmed |
