The dual-site agonist for human M2 muscarinic receptors Iper-8-naphtalimide induces mitochondrial dysfunction in Saccharomyces cerevisiae
December 12, 2025
S. cerevisiae is a model to study human GPCRs. N-8-Iper, active against glioblastoma via M2 receptor, causes mitochondrial damage in yeast by binding Ste2, highlighting evolutionary conservation of GPCRs.
Ergosterone-coupled Triazol molecules trigger mitochondrial dysfunction, oxidative stress, and acidocalcisomal Ca2+ release in Leishmania mexicana promastigotes
December 11, 2015
The protozoan parasite Leishmania causes a variety of sicknesses with different clinical manifestations known as leishmaniasis. Investigations looking for new targets or new active molecules focus mainly on the disruption of parasite specific pathways. In this sense, ergosterol biosynthesis is one of the most attractive because it does not occur in mammals. Our results indicate that ergosterone-triazol coupled molecules induce a regulated cell death process in the parasite and may represent starting point molecules in the search of new chemotherapeutic agents to combat leishmaniasis.
