Background:

LysRs-IN-2 is a lysyl-tRNA synthetase (KRS) inhibitor with IC50s of 0.015 μM and 0.13 μM for Plasmodium falciparum lysyl-tRNA synthetase (PfKRS) and Cryptosporidium parvum lysyl-tRNA synthetase (CpKRS), respectively[1].

LysRs-IN-2 is active against whole-cell bloodstream P. falciparum 3D7 (EC50=0.27 μM), HsKRS (IC50=1.8 μM), HepG2 cells (EC50=49 μM), and Cryptosporidium parvum (EC50=2.5 µM)[1].

LysRs-IN-2 (1.5 mg/kg; orally once a day for 4 days) reduces parasitemia by 90% in the murine P. falciparum SCID model. LysRs-IN-2 (20 mg/kg; orally once a day for 7 days) reduces parasite shedding in NOD SCID gamma mice and INF-γ-knockout mice (Cryptosporidium mouse models)[1].
