The parasite is the etiologic agent of trichomoniasis, the most common non-viral sexually transmitted disease worldwide. This infection often remains asymptomatic and is related to several health complications. The traditional treatment for trichomoniasis is the use of drugs of the 5-nitroimidazole family, such as metronidazole; however, scientific reports indicate an increasing number of drug-resistant strains.

Background: Iron is an essential element for cellular functions, such as energy metabolism. Trichomonas vaginalis, a human urogenital tract pathogen, is capable of surviving in the environment without sufficient iron supplementation. Pseudocysts (cyst-like structures) are an environmentally tolerated stage of this parasite while encountering undesired conditions, including iron deficiency.

Recent Advances in the Development of Triose Phosphate Isomerase Inhibitors as Antiprotozoal Agents.

Curr Med Chem

May 2022

Laboratorio de Biotecnología Farmacéutica, Centro de Biotecnología Genómica, Instituto Politécnico Nacional, 88710 Reynosa, México.

Article Synopsis
  • * The glycolysis pathway, particularly the enzyme triose phosphate isomerase (TIM), is highlighted as a potential target for developing antiprotozoal agents because of structural differences between protozoan TIM and human TIM, allowing for selective inhibitors.
  • * The review covers various drug design strategies and successful TIM inhibitors with specific chemical structures that interact with the enzyme to impede its activity, showcasing their potential in treating diseases such as Chagas disease and malaria.

Protein secretion in eukaryotic cells is a well-studied process, which has been known for decades and is dealt with by any standard cell biology textbook. However, over the past 20 years, several studies led to the realization that protein secretion as a process might not be as uniform among different cargos as once thought. While in classic canonical secretion proteins carry a signal sequence, the secretory or surface proteome of several organisms demonstrated a lack of such signals in several secreted proteins.

Background: Iron plays essential roles in the pathogenesis and proliferation of Trichomonas vaginalis, the causative agent of the most prevalent non-viral human sexually transmitted infection. We previously demonstrated that under iron deficiency, the endogenous nitric oxide (NO) is accumulated and capable of regulating the survival of T. vaginalis.
