library led to the identification of 2,2′‐methylenebis(5‐(4‐bromophenyl)‐4,4‐dimethyl‐2,4‐dihydro‐3H‐pyrazol‐3‐one), a phenyldihydropyrazolone dimer, which shows an in vitro pIC50 value of 5.4 against Trypanosomacruzi. Initial optimization was done by varying substituents of the phenyl ring, after which attempts were made to replace the phenyl ring. Finally, the linker between the dimer units was varied
