title: Toxicological studies on a new macrolide antibiotic, midecamycin acetate (miokamycin). Part I-1. Acute toxicity in mice.
abstract: Miokamycin (MOM) is a derivative of midecamycin, a macrolide antibiotic isolated from a culture broth of Streptomyces mycarofaciens. The objective of this study was to determine the acute toxicity of MOM, non-crystalline solid, in male and female mice (Jcl-ICR, SPF, 5-week-old) after single i.p., and p.o. administration of this material at a dose level of 5,000 mg/kg as the maximum physically applicable dose. MOM, non-crystalline solid, exhibited no acute toxicity in the present study. LD0 values were estimated as more than 5,000 mg/kg in each route of administration.
