3-Alkylthio-1,2,4-triazine dimers with potent antimalarial activity
摘要:
We report on the discovery of 3-alkylthio-1,2,4-triazine dimers that are potently toxic to Plasmodium falciparum, with single digit nanomolar activity, and up to several thousand-fold lower toxicity to mammalian cells. They are equipotent against chloroquine-resistant strains of P. falciparum. (c) 2010 Elsevier Ltd. All rights reserved.

A protocol for C–H/C–H cross-coupling reaction between 7-aminocoumarins and 1,2,4-triazines has been developed. The reaction was carried out under heptafluorobutyric acid catalysis providing products with yield up to 91%. The applicability and scope of the proposed method was demonstrated on 25 compounds containing different substituents both in the triazine ring and at the nitrogen atom of 7-aminocoumarins
