N‐Pyrazolyl‐ and N‐Triazolylamines and ‐Ureas as Antileishmanial and Antitrypanosomal Drugs

ChemMedChem, Volume 19, Issue 15, August 1, 2024.
Within the framework of “drugs for neglected disease initiative (DNDi)”, novel relationships between the structure of 3‐arylpyrazoles and 3‐aryl‐1,2,4‐triazoles with different substituents in 5‐position and their antileishmanial and antitrypanosomal activity are investigated Activity against L. infantum is not detected.

Late‐Stage Diversification of Pyrazoles as Antileishmanial Agents

ChemMedChem, Volume 19, Issue 8, April 16, 2024.
Within the framework of “drugs for neglected disease initiative (DNDi)”, Pd‐catalyzed Sonogashira and Suzuki‐Miyaura cross‐coupling reactions were used to introduce diverse substituents in 3‐position of pyrazoles. The 5‐position of pyrazoles was supplied with amino, acylamino and ureido moieties.

Color preference of Sergentomyia minuta (Diptera: Phlebotominae) determined using Flebocollect Do It Yourself light traps based on LED technology

Parasitology Research, 2022
Whether phlebotomine sand flies show a preference for different light colors remains controversial. As light-capture methods are widely used to study sand flies, knowing the visual stimuli they respond to could help the design of novel control tools to ...

The Phlebotomine sand fly fauna of Switzerland revisited

Medical and Veterinary Entomology, Volume 38, Issue 1, Page 13-22, March 2024.
A new inventory of Phlebotomine sand flies of Switzerland has been created. Four species were recorded south to the Alps: Phlebotomus perniciosus, P. neglectus, P. mascittii and Sergentomyia minuta; and only P. mascittii north to the Alps. Phlebotomus neglectus is recorded for the first time in the country, most probably spreading from Northern Italy ...

Microbiota do trato digestivo de fêmeas de Lutzomyia longipalpis (Lutz & Neiva, 1912) (Diptera: Psychodidae) provenientes de colônia alimentadas com sangue e com sangue e sacarose Digestive tract microbiota in female Lutzomyia longipalpis (Lutz & Neiva, 1912) (Diptera: Psychodidae) feeding on blood meal and sacarose plus blood meal

Cadernos de Saúde Pública, 2001
Há poucos estudos sobre a microbiota do trato digestivo de flebotomíneos, considerando-se que o sangue não é o único alimento ingerido. Os flebotomíneos, tanto os machos como as fêmeas, alimentam-se de açúcares, provenientes de várias fontes ...
