Research Summary

Dr. Siqueira-Neto’s has 15 years of international experience in discovering and developing therapies for infectious diseases, including SARS-CoV-2, causing agent of COVID-19. His participation in discoveries have brought drug candidates to pre-clinical (Pyronaridine for Chagas Disease) and clinical stages (SLV213, aka K777, for COVID-19) of development. The Siqueira-Neto Lab is focused on the validation of screening assays enabling interrogation of large libraries of small molecules and natural products for the identification of hits with relevant biological activity to treat human diseases, especially but not limited to infectious diseases. The lab also investigates the interaction of host and pathogens to further understand disease pathogenesis and to identify new druggable targets.

Dr. Siqueira-Neto has recently given talks to the non-scientific public to explain about COVID-19 and the principles of immunization through the vaccine.
