Pretomanid-d4 (PA-824-d4) 是 Pretomanid 的氘代物。Pretomanid (PA-824) 是一种抗生素，可用于肺部多重耐药性结核病的研究。Pretomanid 对结核病 (MTB) 具有亚微摩尔作用活性。Pretomanid 对 MTB 泛敏感和抗 Rifampin 的临床分离株的 MIC 值为 0.015 至 0.25 μg/mL。
Pretomanid-d4 (PA-824-d4) is the deuterium labeled Pretomanid. Pretomanid (PA-824) is an antibiotic used for the research of multi-drug-resistant tuberculosis affecting the lungs. Pretomanid exhibits a sub-micromolar MIC against M. tuberculosis (MTB). The MIC values of PA-824 against a panel of MTB pan-sensitive and Rifampin mono-resistant clinical isolates range from 0.015 to 0.25 µg/mL[1][2].
Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs[1].
