A series of fluorinated 1,2,4‐triazolo[1,5‐ a ]pyrimidine‐6‐carboxylic acid derivatives was designed and synthesized as fluoroquinolone analogues. The synthesized compounds were screened against Mycobacterium tuberculosis H 37 R v strain at 6.25 μg/mL concentration. Compound 4 , the 7‐oxo‐2‐(trifluoromethyl)‐4,7‐dihydro‐1,2,4‐triazolo[5,1‐ a ]pyrimidine‐6‐carboxylic acid was found to be a very potent inhibitor, being able to inhibit 92% growth of M. tuberculosis H 37 R v at 6.25 μg/mL concentration. At the same time, it proofed to be nontoxic to mammalian cells (IC 50 > 62.5 μg/mL in VERO cells).
