In Vitro Thiacetazone is a prodrug that is activated by the mycobacterial monooxygenase EthA, which is also the activator of two other anti-tuberculosis agents, Ethionamide and Isoxyl[3].
In Vivo The Km and Vmax values for the N-deacetylation of Thiacetazone are 0.57 mM and 0.123 nmol of p-aminobenzaldehydethiosemicarbazone formed/min/mg cytosolic protein, respectively. The ability to metabolize Thiacetazone is the same in the livers of cat, mouse and human, but lagged significantly in that of rat[2].
