Flumequine- 13 C 3 是 13 C 3 标记的 Flumequine。Flumequine (R-802) 是一种喹诺酮类抗生素，为拓扑异构酶 II (Topoisomerase II) 抑制剂，IC50 值为 15 μM (3.92 μg/mL)。 Flumequine- 13 C 3 is the 13 C 3 labeled Flumequine. Flumequine (R-802) is a quinolone antibiotic, and acts as a topoisomerase II inhibitor, with an IC50 of 15 μM (3.92 μg/mL). 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
