A molecular mechanism for eflornithine resistance in African trypanosomes [PDF]

, 2010
Human African trypanosomiasis, endemic to sub-Saharan Africa, is invariably fatal if untreated. Its causative agent is the protozoan parasite Trypanosoma brucei.

Spermidine Suppressed the Inhibitory Effects of Polyamines Inhibitors Combination in Maize (Zea mays L.) Seedlings under Chilling Stress

Plants, 2021
Chilling stress greatly inhibited the seed germination, plant growth, development and productivity in this study. The current research aimed to study the effects of different polyamine (PA) inhibitor combinations (Co), e.g., D-arginine (D-Arg ...

Polyamine biosynthesis in Xenopus laevis: the xlAZIN2/xlODC2 gene encodes a lysine/ornithine decarboxylase.

PLoS ONE, 2019
Ornithine decarboxylase (ODC) is a key enzyme in the biosynthesis of polyamines, organic cations that are implicated in many cellular processes. The enzyme is regulated at the post-translational level by an unusual system that includes antizymes (AZs ...

Pharmacological Approaches to Antitrypanosomal Chemotherapy

Memorias do Instituto Oswaldo Cruz, 1999
There is an urgent need for new drugs for the chemotherapy of human African trypanosomiasis, Chagas disease and leishmaniasis. Progress has been made in the identification and characterization of novel drug targets for rational chemotherapy and ...

Inhibition of putrescine biosynthesis enhanced salt stress sensitivity and decreased spermidine content in rice seedlings

Biologia Plantarum, 2017
The effect of polyamine biosynthesis inhibitors on the salt stress response of rice seedlings was investigated. For this, DL-α-difluoromethylarginine (DFMA) and DL-α-difluoromethylornithine (DFMO), two competitive inhibitors of arginine decarboxylase ...

Antizyme Inhibitors in Polyamine Metabolism and Beyond: Physiopathological Implications

Medical Sciences, 2018
The intracellular levels of polyamines, cationic molecules involved in a myriad of cellular functions ranging from cellular growth, differentiation and apoptosis, is precisely regulated by antizymes and antizyme inhibitors via the modulation of the ...

Untargeted metabolomics reveals a lack of synergy between nifurtimox and eflornithine against trypanosoma brucei [PDF]

, 2012
A non-targeted metabolomics-based approach is presented that enables the study of pathways in response to drug action with the aim of defining the mode of action of trypanocides.

Glucocorticoids and Polyamine Inhibitors Synergize to Kill Human Leukemic CEM Cells

Neoplasia: An International Journal for Oncology Research, 2002
Glucocorticoids are well-known apoptotic agents in certain classes of lymphoid cell malignancies. Reduction of intracellular polyamine levels by use of inhibitors that block polyamine synthesis slows or inhibits growth of many cells in vitro.
