analogues against gametocytes revealed their moderate activity (IC50: 1-5 μM) against late stage P. falciparum gametocytes, while the evaluation of activity against P. berghei liver stages identified one compound (3) with 3-fold greater activity than the parent AST compound. Mechanistic studies showed a strong correlation between in vitroinhibition of β-hematin formation by the AST derivatives and their
