4-aminoquinolines chloroquine amodiaquine and next-generation analogues


Antimalarial drugs with the 4-aminoquinoline scaffold such as the important drugs, chloroquine (CQ) and amodiaquine (AQ), have been used to prevent and treat malaria for many years A summary of the features that must be considered in the design of the ideal 4-aminoquinoline is listed in Fig. Introducing New Antimalarial Analogues of Chloroquine and Amodiaquine: A Narrative Review which may constitute the next generation of antimalarial drugs with the 4 …. Dejan M. The parasite growth was then monitored to between 2–7% when donor mice were selected for subsequent passage into the next naive group of three mice. Hence, the aim of this review article is to introduce of the novel synthetic analogues of CQ and AQ, which may constitute the next generation of antimalarial drugs with the 4-aminoquinoline scaffold. The compound GIQ was inactive in all doses tested (highest dose 10 μM) resistance mechanism, the development of new 4-amino-quinoline derivatives is a valid strategy. Publisher.

It is a devastating disease that also extracts huge economic costs from the poorest countries in endemic regions. (2003) synthesized a new series of amodiaquine analogues by interchanging hydroxyl at the 3′ position and the 4′ Mannich side-chain function of anilino moiety of quinoline.
