CAS:2-((2-Methyl-1-(propionyloxy)propoxy)(4-phenylbutyl)phosphoryl)acetic acid (KZPBA) is a zoonotic antibiotic that has been shown to be active against agalactiae. It is a prodrug, which is metabolized to the active form, KZPBA, in humans and other mammals. The mechanism of action of KZPBA is not yet known; however, it has been hypothesized that its activity may be due to inhibition of DNA gyrase and topoisomerase IV. This drug has also been shown to have an effect on mastitis in dairy cows.Formula:C19H29O6PPurity:Min. 95%Molecular weight:384.4 g/molPrednisolone Impurity 21
