title: Efficacy of S-adenosylhomocysteine hydrolase inhibitors, D-eritadenine and (S)-DHPA, against the growth of Cryptosporidium parvum in vitro.
abstract: D-eritadenine and (S)-DHPA are aliphatic adenosine analogues known to target S-adenosylhomocysteine hydrolase (SAHH) and potent antiviral compounds. In the present study, we demonstrate that these two compounds also display efficacy against recombinant SAHH enzyme of the protozoan parasite Cryptosporidium parvum, as well as inhibition of parasite growth in vitro. Our data confirm that SAHH could serve as a rational drug target in cryptosporidial infection and antiviral adenosine analogues are potential candidates for drug development against cryptosporidiosis.
