Discontinued product2-((2-Methyl-1-(propionyloxy)propoxy)(4-phenylbutyl)phosphoryl)acetic acid
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/molRef: 3D-IM27637

Discontinued productPteroic acid, min95%
CAS:Pteroic acid is a naturally occurring substance found in plants and animals. It has inhibitory activities against enzymes such as butyrate kinase, acetyl-CoA synthetase, and glutamate dehydrogenase. Pteroic acid is used to synthesize quinoxalines, which are used for the treatment of cancer. Pteroic acid also inhibits cell growth by inhibiting protein synthesis. This is done by conjugating with amino acids and inhibiting their uptake into the ribosome. The inhibition of glutamate dehydrogenase may be due to its ability to reduce levels of glutathione, which is an inhibitor of this enzyme.
