CAS:Tenofovir disoproxil related compound B is a peptidyl prodrug that is metabolized by esterases to tenofovir. It has been shown to be an effective agent against Mycobacterium tuberculosis and other bacterial species. Tenofovir disoproxil related compound B was also found to inhibit protein synthesis in Mycobacterium avium and Mycobacterium smegmatis, but not in Escherichia coli. This drug binds to the ribosome's 30S subunit, which blocks the binding of aminoacyl-tRNA and prevents the formation of peptide bonds. The mechanism of action for this drug is similar to that of the antibiotic erythromycin.Formula:C8H9N5Purity:Min. 98 Area-%Molecular weight:175.19 g/molAtovaquone Impurity 2
