Chloroquine resistance in Plasmodium falciparum is not reversed by BIBW-22, a compound reversing the multidrug resistance phenotype in mammalian cancer cells.

Abstract excerpt

The pteridine derivative BIBW-22 (4-[N-(2-hydroxy-2-methyl-propyl)-ethanolamino]-2,7-bis(cis-2,6-di methyl-morpholino)-6-phenylpteridine), which had been developed for the treatment of multidrug-resistant cancer and binds to P-glycoprotein, was tested against chloroquine resistant Plasmodium falciparum strains in culture. Based on the result that BIBW-22 enhanced rather than lowered chloroquine resistance in...
