Lourival Domingos Possani, Brazilian-born Mexican toxicologist (Santo Angelo, Rio Grande do Sul State 09 July 1939 –

Authored 500 publications (with about 19,700 citations by Google Scholar, about 17,000 by ResearchGate and about16,600 by Research.com)

Described a number of novel toxins form scorpions, reptiles, molluscs, spiders and wasps

Described the toxic venom peptides that affect the function of ion channels of excitable cells

First to report peptides that block potassium (K⁺) channels (noxiustoxin 1986 and ergtoxin from Centruroides noxius)

Found peptide toxins with immune-modulatory function and that with antibiotic and antiparasitic activity

Other peptides with interesting biological activities such as specific toxins for insects and crustaceans

With F.Z. Zamudio discovered hadrurine (from Hadrurus gertschi) and scorpine (from Pandinus imperator) with microbicide activity (2000)

Isolated and characterized a peptide with antiepileptic activity from Centruroides limpidus limpidus (1994)

Designed and synthesized about a hundred peptides
