LeuRS-IN-1 is a potent, orally active M. tuberculosis leucyl-tRNA synthetase (M.tb LeuRS) inhibitor. LeuRS-IN-1 has IC50 and Kd values of 0.06 μM, 0.075 μM for M.tb LeuRS, respectively[1]. LeuRS-IN-1 inhibits human cytoplasmic LeuRS (IC50=38.8 μM), and HepG2 protein synthesis (EC50=19.6 μM)[2].

Target	M.tb LeuRS:0.06 μM (IC50) M.tb LeuRS:0.075 μM (Kd) human cytoplasmic LeuRS:38.8 μM (IC50) HepG2 protein synthesis:19.6 μM (EC50)
In Vitro	LeuRS-IN-1 (compound 13) has a MIC value of 0.02 μg/mL for M.tb H37Rv bacteria[1]. LeuRS-IN-1 (compound 3a) (48 h) induces HepG2 cell toxicity with an EC50 value of 65.8 μM[2].
In Vivo	LeuRS-IN-1 (100 mg/kg; orally daily for 14 days) reduces lung CFU value in acute tuberculosis (TB) mice[1]. LeuRS-IN-1 (33 mg/kg; orally 5 days a week for 4 weeks) reduces lung and spleen CFU values in chronic TB mice[1].

Result: Reduced lung CFU value in mice. Animal Model: Murine BALB/c model of chronic TB infection[1] Dosage: 33 mg/kg Administration: Orally 5 days a week for 4 weeks after infection with M. tuberculosis Erdman with a low-dose aerosol 21 days prior (start). Result: Reduced lung and spleen CFU values in mice.
