Identification of Ecdysone Hormone Receptor Agonists as a Therapeutic Approach for Treating Filarial Infections. [PDF]

open access: yesPLoS Neglected Tropical Diseases, 2016
BACKGROUND:A homologue of the ecdysone receptor has previously been identified in human filarial parasites. As the ecdysone receptor is not found in vertebrates, it and the regulatory pathways it controls represent attractive potential chemotherapeutic ...

In Silico Identification of Chemicals Capable of Binding to the Ecdysone Receptor. [PDF]

open access: yesEnviron Toxicol Chem, 2020
The process of molting, known alternatively as ecdysis, is a feature integral in the life cycles of species across the arthropod phylum. Regulation occurs as a function of the interaction of ecdysteroid hormones with the arthropod nuclear ecdysone ...
