  • Patent number: 11834391
    Abstract: The present invention provides compounds that have antimalarial activity. More in particular, the present invention provides novel compounds that are analogues of pantothenamides. The pantothenamide analogues of this invention have particularly low IC50 values against the asexual blood stages and gametocytes of malaria parasites. Furthermore, the pantothenamide analogues of this invention are characterized by low hepatic metabolism. Therefore, pantothenamide analogues of the invention are particularly suitable for use in therapeutic and/or prophylactic treatment of protozoan infections in a human or animal subject in need thereof. The invention further provides pharmaceutical formulations comprising the pantothenamide analogues as well as the therapeutic and/or prophylactic uses of the pantothenamide analogues and pharmaceutical formulations comprising them.

  • Patent number: 9388156
    Abstract: The invention relates to novel compounds that are useful for modulating mitochondrial morphology and/or expression of OXPHOS enzymes and/or cellular ROS. The compounds are derivatives of TroloxrM wherein the carboxylic acid moiety is replaced by an amide moiety and wherein the nitrogen atom of the amide moiety is connected via a linker to a cationic nitrogen atom. The compounds of the invention are formulated into pharmaceutical or cosmetic compositions. The invention further relates to methods wherein the compounds of the invention are used for treating or preventing mitochondrial disorders, conditions associated with mitochondrial dysfunction, including adverse drug effects, and/or neoplastic diseases. The invention also relates to cosmetic methods for treating or delaying further aging of the skin and veterinary applications.
