A systematic study of P2 and P3 substitution in a series of vinyl sulfone cysteine protease inhibitors is described. The introduction of a methyl substituent in the P2 phenylalanine aryl ring had a favorable effect on protease inhibition and conferred modest selectivity for rhodesain over cruzain. Rhodesain selectivity could be enhanced further by combining these P2 modifications with certain P3 amide substituents.
