Leishmaniasis is an infectious disease with several limitations regarding treatment schemes. This work reports the anti-Leishmania activity of spiroacridine compounds against the promastigote (IC = 1.1 to 6.0 µg / mL) and amastigote forms of the best compounds (EC = 4.9 and 0.9 µg / mL) inLeishmania (L.) infantumand proposes an in-silico study with possible selective therapeutic targets for L. infantum. The substituted dimethyl-amine compound (AMTAC 11) showed the best leishmanicidal activity in vitro, and was found to interact with TryRandLdTopoI. comparisons with standard inhibitors were performed, and its main interactions were elucidated. Based on the biological assessment and the structure-activity relationship study, the spiroacridine compounds appear to be promisinganti-leishmaniachemotherapeutic agents to be explored.

New leishmanicidal products are needed for the treatment to be effective, since current drugs are toxic to healthy human/animal cells and have low efficacy against the parasite. Bioactive compounds from microalgae, such as lectins, can be explored as new anti-Leishmania candidates. This study aimed to evaluate the cytotoxic and anti-Leishmania action of the cell extract (CE) and lectin (CVU) from Chlorella vulgaris biomass.

Leishmaniasis encompasses a group of neglected diseases caused by flagellated protozoa belonging to the genus, associated with high morbidity and mortality. The search for compounds with anti- activity that exhibit lower toxicity and can overcome the emergence of resistant strains remains a significant goal. In this context, the calpain inhibitor MDL28170 has previously demonstrated deleterious effects against promastigote forms of , which led us to investigate its role on axenic amastigote forms.

Leishmaniasis, caused by Leishmania parasites, presents a major global health challenge due to limitations of existing treatments, including toxicity, side effects, drug resistance, and high costs. This study utilized the MuDRA (Multi-Descriptor Read Across) model for virtual screening to identify potential anti-Leishmania infantum compounds. A set of 15 terpenes and steroids was screened, leading to the identification of four promising candidates-lupeol, xylodiol, morolic acid, and trachyloban-18-oic acid.
