Choline analogues such as bis-thiazolium salts are thought to inhibit choline transport into Plasmodiuminfected
erythrocytes, thus preventing parasite PC biosynthesis, and also to interact with plasmodial haemoglobin degradation
in the food vacuole. This new and multiple mode of action is a major asset of these new class of antimalarials, as
they could help delay resistance development. We synthesized and designed various sets of analogues, notably prodrugs,
since the oral bioavailability of bis-thiazolium salts is relatively low. The chemistry underlying this synthesis relies on inexpensive and readily available starting materials and is straightforward. This is essential since the ultimate objective is to
obtain affordable and orally available drugs for uncomplicated malaria treatment.
Keywords: Antimalarials, choline analogues, phospholipid, plasmodium, prodrugs, thiazolium salts.
