JPC 2067 is a novel dihydrotriazine dihydrofolate reductase inhibitor that is being developed as an antimalarial therapeutic. We evaluated the in vitro activity of JPC 2067 alone and in combination with sulfamethoxazole (SMX) against a panel of nocardia isolates. The MIC(50)s and MIC(90)s for JPC 2067, SMX, and the combination were 0.125 μg/ml and 4 μg/ml, 16 μg/ml and 32 μg/ml, and 0.03 μg/ml and 2 μg/ml, respectively. JPC 2067 alone and in combination with SMX should be evaluated further to understand its clinical potential.
