Propionylmaridomycin

Description

Propionylmaridomycin is a macrolide antibiotic with antibacterial activity. Propionylmaridomycin is rapidly absorbed from the gastrointestinal tract and rapidly distributed to tissues. Propionylmaridomycin radioactivity levels in the liver, kidneys, and lungs were significantly higher than in plasma, while distribution to the brain was less. Propionylmaridomycin is excreted primarily through the feces, and the high fecal recovery rate is due to unabsorbed compounds and biliary excretion of compounds and their metabolites. Propionylmaridomycin exhibits the highest antibacterial activity in the lungs. Propionylmaridomycin is completely converted to several metabolites in rats, of which 4-depropionyl-9-propionylmaridomycin was identified as the major metabolite.
