In cellulo and in vivo assays for compound testing against Trypanosoma cruzi

Abstract

Here, we describe a combined in cellulo and in vivo approach to identify compounds with higher potential for efficient inhibition of Trypanosoma cruzi. Phase I of in cellulo assays is designed to exclude inactive or toxic compounds, while phase II is designed for accurate IC₅₀, CC₅₀, and selective index (SI) determination. Compounds showing high SI are tested using in vivo infection models in parallel with benznidazole to assess their efficacy relative to a reference drug used for Chagas disease treatment. For complete details on the use and execution of this protocol, please refer to Marek et al. (2021).¹.
