Twelve t-butylperoxyamines (6 17) were synthesized as targeted antimalarials and evaluated for antimalarial activity in vivo against Plasmodium berghei in mice and in vitro against both chloroquine sensitive and chloroquine resistant strains of Plasmodium falciparum. Compound 8 was found to have highest potency with activity at 80 and 160 mg/kg dose in vivo and compound I I exhibited highest efficacy in vitro. (C) 2001 Elsevier Science Ltd. All rights reserved.

5-dicarboxylic amides. This is a new synthesis of isoxazole derivatives. 2) Twenty kinds of 4-substituted isoxazole-3,5-dicarboxylic amides, including aliphatic, aromatic and heterocyclic derivatives, have been prepared. 3) Seven of the above-mentioned amides have been hydrolyzed to give the corresponding 4-substituted isoxazole-3,5-dicarboxylic acids. 4) Some Schiff bases have been described.
