  摘要：

  Thirteen new analogues (32-40, 45-48) of recently discovered potent blood-schizontocidal antimalarial agent, 2-tertbutylprimaquine (2) are synthesized and evaluated for in vivo antimalarial activities against drug-sensitive P. berghei strain and multi-drug resistant P. yoelii nigeriensis strain. Two of the amino acid conjugates (47-48) have exhibited potent antimalarial activities similar to that of 2 against both drug-sensitive and multi-drug resistant strains. (C) 2004 Elsevier Ltd.

  In continuing our search of potent antimalarials based on 8-aminoquinoline structural framework, three series of novel bis(8-aminoquinolines) using convenient one to four steps synthetic procedures were synthesized. The bisquinolines were evaluated for in vitro antimalarial (Plasmodium falciparum), antileishmanial (Leishmania donovani), antimicrobial (a panel of pathogenic bacteria and fungi), cytotoxicity

  To eliminate an unwarranted metabolic pathway of the quinoline ring, a set of two compounds, where C-2 position of the antimalarial drug primaquine is blocked by metabolically stable bulky alkyl group are synthesized. Compound 2 [R = C(CH3)(3)] of the series has produced excellent antimalarial efficacy against P. berghei and highly virulent multidrug-resistant P. yoelii nigeriensis strain in vivo. Compound 2 was also evaluated for methemoglobin (MetHb) toxicity. This study describes the discovery of a highly potent blood-schizontocidal antimalarial analogue 2, completely devoid of MetHb toxicity.

  Three new series of 8-aminoquinolines with modifications in the side-chain by conjugation with amino acids, dipeptides and pseudodipeptides have been synthesized. The synthesized compounds were tested for in vitro antimalarial activity against chloroquine-sensitive and chloroquine-resistant Plasmodium falciparum strains, in vitro cytotoxicity in mammalian kidney cells (Vero), in vitro antileishmanial activity against Leishmania donovani, in vitro antimicrobial activity and in vitro inhibition of beta-haematin formation. The promising compounds were also evaluated for in vivo blood-schizontocidal antimalarial activity against Plasmodium berghei infected mice. The analogues 55 and 101 produced highest antimalarial activities, in vitro. Analogues 52 and 59 exhibited promising antileishmanial and broad spectrum of antifungal activities, respectively.
