Metabolite-dependent regulation of gene expression in trypanosoma brucei [PDF]

, 2013
Mechanisms regulating gene expression in trypanosomatid protozoa differ significantly from those in other eukaryotes. Transcription of the genome appears to be more or less constitutive with the polyadenylation and trans-splicing of large polycistronic ...

Structure-based design and synthesis of antiparasitic pyrrolopyrimidines targeting pteridine reductase 1 [PDF]

, 2014
The treatment of Human African Trypanosomiasis remains a major unmet health need in sub-Saharan Africa. Approaches involving new molecular targets are important and pteridine reductase 1 (PTR1), an enzyme that reduces dihydrobiopterin in Trypanosoma spp.

The trans-Sialidase from Trypanosoma cruzi a Putative Target for Trypanocidal Agents [PDF]

The Open Parasitology Journal, 2010
Trypanosomatid protozoa are parasites of considerable medical and economical importance because they are the causative agents of chronic human and livestock diseases endemic in developing countries. Trypanosoma cruzi is the causative agent of Chagas´ disease, present in most of Latin America. The biology of this parasite presents some unusual features,

Scalable Access to N‑Acylindole Linkages: Enabling the Synthesis of Antitrypanosomal Noncanonical Cyclic Peptides for Chagas Disease

Angewandte Chemie International Edition, EarlyView.
A gram‐scale supply of bulbiferamide A, which features a rare N‐acylindole linkage and possesses potent inhibitory activity against Trypanosoma cruzi epimastigotes (IC50 = 4.1 µM)—the causative parasite of Chagas disease—was successfully achieved. Moreover, the cyclization strategy developed in this study facilitated the synthesis of noncanonical ...

Antioxidant and Cytotoxic Properties of Piper spp. Volatile Oils That Inhibit Pathogenic Microorganisms

Flavour and Fragrance Journal, EarlyView.
The samples were fungicidal against Candida, with MICs ranging from 62.5 to 250 μg/mL, and fungistatic against Penicillium adametzii, Aspergillus flavus and A. niger, with MICs of 1000 μg/mL. The volatile oils of Piper aduncum and Piper marginatum reduced the viability of MDA‐MB231 cells.
