Malaria Pharmacology Comments
The Plasmodium cGMP-dependent protein kinase (PfPKG) is an attractive target for next-generation antimalarials as it has been implicated in multiple cellular activities at various stages of the parasite lifecycle [1]. A medicinal chemistry programme has identified an imidazopyridine series that demonstrates promising activity and may warrant further development [2].
