A novel series of fluorine-containing benzoxazinyl-oxazolidinones were designed and synthesized as antidrug-resistant tuberculosis agents possessing good activity and improved pharmacokinetic profiles. Compound 21 exhibited not only outstanding in vitro activity with a MIC value of 0.25-0.50 mu g/mL against drug-susceptible H(37)Rv strain and two clinically isolated drug-resistant Mycobacterium tuberculosis strains, but also acceptable in vitro ADME/T properties. Moreover, this compound displayed excellent mouse pharmacokinetic profiles with an oral bioavailability of 102% and a longer elimination half-life of 4.22 h, thereby supporting further optimization and development of this promising lead series.
