We have identified a series of amino-amide boronates that are potent and specific inhibitors of the 20S proteasome (20S) β5 active site and that exhibit fast-acting antimalarial activity. They selectively inhibit the growth of compared with a human cell line and exhibit high potency against field isolates of and They have a low propensity for development of resistance and possess liver stage and transmission-blocking activity. Exemplar compounds, MPI-5 and MPI-13, show potent activity against infections in a SCID mouse model with an oral dosing regimen that is well tolerated. We show that MPI-5 binds more strongly to 20S than to human constitutive 20S (20Sc). Comparison of the cryo-electron microscopy (EM) structures of 20S and 20Sc in complex with MPI-5 and 20S in complex with the clinically used anti-cancer agent, bortezomib, reveal differences in binding modes that help to explain the selectivity. Together, this work provides insights into the 20S proteasome in , underpinning the design of potent and selective antimalarial proteasome inhibitors. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
