Abstract: The invention relates to dual molecules formed from coupling products complying with the formula wherein A represents a residue of molecule with anti-malarial activity, Y1 and Y2, represent a linear or branched alkylene chain at C1 to C5, or either Y1 or Y2 is absent, U is an amine, amide, sulphonamide, carboxyl, ether or thioether function, said function linking Y1 and Y2, Z1 and Z2, represent a linear arylene or alkylene, or either Z1 or Z2 is absent, or Z1+Z2 together represent a cyclic or polycyclic structure including the junction carbons Ci and Cj, R1 and R2, represent a hydrogen atom or a functional group capable of increasing the hydrosolubility of the dual molecule, Rx and Ry form a cyclic peroxide with 4 to 8 chain links, Cj being one of the peaks of said cyclic peroxide, or -Rx or Ry is a cyclic peroxide with 4 to 8 chain links, which may comprise 1 or 2 additional oxygen atoms in the cyclic structure, and one or more substituents R3, identical or different, at least one R3 representing a hal
