[EN] The present invention relates to novel geldanamycin derivatives which have antitumor and antiparasitic properties. The geldanamycin derivatives disclosed herein have antitumor properties in humans due to their interaction with human heat shock protein 90 (hsp90). The human parasites Plasmodium falciparum, Trypanosoma Cruzi, and Leishmania donovani are lethally susceptible to exposure to geldanamycin via complexation of geldanamycin with their homologs (Pfhsp90, hsp83, and hsp90, respectively) of the human hsp90. The geldanamycin derivatives disclosed herein also interact with these parasitic hsp90 homologs so as to have antiparasitic properties. [FR] La présente invention concerne des dérivés innovants de la geldanamycine qui ont des propriétés antitumorales et antiparasitaires. Chez les humains, les propriétés antitumorales des dérivés de la geldanamycine divulgués ici sont dues à l'interaction desdits dérivés avec la protéine de choc thermique (Heat Shock Protein 90 ; hsp90) humaine. Les parasites humains Plasmodium falciparum, Trypanosoma cruzi et Leishmania donovani sont létalement sensibles à une exposition à la geldanamycine en raison d'une complexation de la geldanamycine avec leurs homologues (respectivement Pfhsp90, hsp83 et hsp90) de la hsp90 humaine. Les dérivés de la geldanamycine divulgués ici interagissent également avec ces homologues parasitaires de la hsp90 et ils ont donc des propriétés antiparasitaires.
