  Examination of the Mode of Action of the Almiramide Family of Natural Products against the Kinetoplastid Parasite Trypanosoma brucei

  摘要：

  Almiramide C is a marine natural product with low micromolar activity against Leishmania donovani, the causative agent of leishmaniasis. We have now shown that almiramide C is also active against the related parasite Ttypanosoma brucei, the causative agent of human African trypanosomiasis. A series of activity-based probes have been synthesized to explore both the molecular target of this compound series in T. brucei lysates and site localization through epifluorescence microscopy. These target identification studies indicate that the almiramides likely perturb glycosomal function through disruption of membrane assembly machinery. Glycosomes, which are organelles specific to kinetoplastid parasites, house the first seven steps of glycolysis and have been shown to be essential for parasite survival in the bloodstream stage. There are currently no reported smallmolecule disruptors of glycosome function, making the almiramides unique molecular probes for this understudied parasitespecific organelle. Additionally, examination of toxicity in an in vivo zebrafish model has shown that these compounds have little effect on organism development, even at high concentrations, and has uncovered a potential side effect through localization of fluorescent derivatives to zebrafish neuromast cells. Combined, these results further our understanding of the potential value of this lead series as development candidates against T. brucei.

  Leishmaniasis is a debilitating disease caused by protozoan parasites of the genus Leishmania, which affects an estimated 12 million people worldwide. The discovery of new lead compounds for leishmaniasis is therefore a pressing concern for global health programs. The organic extract of a Panamanian collection of the marine cyanobacterium Lyngbya majuscula showed strong in vitro activity in two complementary screens against the tropical parasite Leishmania donovani, the causative agent of visceral leishmaniasis. Chromatographic separation of this complex mixture led to the isolation of the highly N-methylated linear lipopeptides, almiramides A-C (1-3). Comparison with the biological activities of a number of related metabolites and semisynthetic derivatives revealed key features required for activity and afforded one new compound (11) with superior in vitro activity. Subsequent synthesis of a library of simplified analogues led to the discovery of several compounds with improved therapeutic indices to the natural products.
