Result:Showed activity against all gram-positive organisms, and also ram-negative organisms tested with ED50s of <0.25 mg/kg/dose.
-
Animal Model:CD-1 mice, rats[2]
-
Dosage:10 mg/kg approximately
-
Administration:Intraperitoneal injection (pharmacokinetic assay)
-
Result:Exhibited an AUC0-∞ ranging from 1.8-21.82 μg•hr/mL in tissue in mice following a 10-mg/kg i.p. dose. Exhibited slow clearance rate with a t1/2β of 3.2 h, Clp of 0.47 mL/min/kg, AUC0-8 of 284.15 μg•hr/mL.
