Intestinal nematodes or roundworms (aka soil-transmitted helminths or STHs) cause great disease. They infect upwards of two billion people, leading to high morbidity and a range of health problems, especially in infected children and pregnant women. Development of resistance to the two main classes of drugs used to treat intestinal nematode infections of humans has been reported. To fight STH i...

OBJECTIVES The protozoan parasite Giardia lamblia causes giardiasis, a persistent diarrhoea. Nitro drugs such as the nitroimidazole metronidazole and the nitrothiazolide nitazoxanide are used for the treatment of giardiasis. Nitroreductases may play a role in activating these drugs. G. lamblia contains two nitroreductases, GlNR1 and GlNR2. The aim of this work was to elucidate the role of GlNR2...

Soil-transmitted helminths are parasitic nematodes that inhabit the human intestine. These parasites, which include two hookworm species, Ancylostomaduodenale and Necator americanus, the whipworm Trichuristrichiura, and the large roundworm Ascarislumbricoides, infect upwards of two billion people and are a major cause of disease burden in children and pregnant women. The challenge with treating...

Zika virus (ZIKV) infection can be the cause of congenital malformations, including microcephaly in infants and can cause other disorders such as Guillain-Barré syndrome, meningoencephalitis, and myelitis, which can also occur in some infected adults. However, at this time, there is no drug approved to treat ZIKV infection. Drug repurposing is the promptest way to obtain an effective drug durin...
