New 4-aminoquinoline Mannich base antimalarials. 1. Effect of an alkyl substituent in the 5'-position of the 4'-hydroxyanilino side chain.

چکیده
A new series of 4-aminoquinoline Mannich base derivatives have been synthesized, in which the 3'-diethylamino function of amodiaquine (AQ) is replaced by a 3'-tert-butylamino group and an aliphatic hydrocarbon entity is incorporated into the 5'-position of the 4'-hydroxyanilino side chain. Seven alkyl Mannich base derivatives were screened and found to be active against both chloroquine-sensitive and -resistant strains of Plasmodium falciparum in vitro. The propyl and isopropyl alkyl derivatives were found to be the most active; consequently these derivatives were tested against a nonsensitive strain of Plasmodium berghi in vivo and found to be 3-fold more active than AQ, irrespective of the route of administration (oral or intraperitoneal).

متن کاملSynthesis and antimalarial activity of new isotebuquine analogues.
Amodiaquine (AQ) and tebuquine are 4-aminoquinoline antimalarials with Mannich base side chain and are highly effective against chloroquine (CQ)-resistant strains of Plasmodium falciparum. Clinical use of AQ has been severely restricted due to hepatoxicity and agranulocytosis side effects associated with its long term use. Lysosomal accumulation and bioactivation to generate reactive quinoneimi...
متن کاملSynthesis and Antimalarial Screening of Some New Isoquine Analogues
Amodiaquine is a 4-aminoquinoline antimalarial that can cause adverse side effects including hepatic and haematological toxicity. The drug toxicity involves the formation of a reactive metabolite, amodiaquine quinoneimine (AQQI), which binds to cellular macromolecules, leading to hepatotoxicity and agranulocytosis. Interchange of the 3 ́ hydroxyl and the 4 ́ Mannich side-chain function of amodiaq...
