  • Patent number: 10287298
    Abstract: The present invention concerns compounds of formula (I), enantiomers, mixture of enantiomers, diastereoisomers and mixture of diasteroisomers thereof formula (I): wherein at least one of W, X and Y is selected from the group consisting of —NR1R2; —NR3—(CH2)n—NR4R5; —O—(CH2)n—NR4R5; —NR3—(CH2)n—N?R6R7R8; and —O—(CH2)n—N?R6R7R8 and Z is a functional group capable of chelating iron salts. The present invention also concerns the compounds of formula (I) for use as a drug, in particular, in the treatment of cancer and malaria.

  • Patent number: 7910744
    Abstract: The invention relates to a method for the manufacture of substituted phosphanes and substituted phosphanes manufactured according to the method. Phosphanes, phosphane oxides, sulfides or selenides are used as ligands in coordination compounds. They play a central role in controlling the activity and selectivity of catalysts. The object is achieved by the invention by synthesizing heterocyclic substituents on aromatic groups by introducing acetyl groups. In this manner, previously unknown representatives of the families of phosphanes, phosphane oxides, sulfides and selenides are made accessible.
