Leishmaniasis is a major public infectious disease caused by the genus Leishmania. No effective drug or vaccination strategy for leishmaniasis has been designed yet. Several intracellular Leishmania antigens have been recognized to serve in vaccination, ensuring long-lasting protection against Leishmania infection. Lipophosphoglican 3 (LPG3) as a member of the heat shock protein 90 family involves in the synthesis of lipophosphoglycan (LPG) and implicates in parasite virulence. Regarding the immunological properties of LPG3 particularly its N-terminal fragment, it would be considered as a favourable adjuvant in Leishmania vaccination.

Introduction: Leishmaniasis is a tropical parasitic disease caused by the protozoan Leishmania which remains a significant global health concern with diverse clinical manifestations. Transmitted through the bite of an infected sandfly, its progression depends on the interplay between the host immune response and the parasite. The disease outcome is linked to macrophage polarisation into M1 and M2 phenotypes.

Visceral leishmaniasis is a systemic disease that affects various internal organs and represents the most severe and fatal form of leishmaniasis. Conventional treatment presents significant challenges, such as prolonged management in hospital settings, high toxicity, and an increasing growing number of cases of resistance. In previous studies, our research group demonstrated the effective and selective activity of the 2-amino-thiophene derivative SB-83 in preclinical models of cutaneous leishmaniasis.

There is no consensus in the literature regarding the ideal protocol for obtaining and preparing cell samples for untargeted metabolomics. Nevertheless, the procedures must be carefully evaluated for proper and reliable results for each organism under study. This work proposes a novel protocol for determining intracellular metabolites in Leishmania promastigotes and is fully optimized for application in conjunction with gas chromatography-mass spectrometry platforms.

Background/objectives: New drugs are required for the treatment of liver cancers and protozoal parasite infections. Analogs of the known anticancer active and antileishmanial 2',4',6'-trimethoxychalcone SU086 were prepared and investigated.
Methods: The chalcones were prepared according to the Claisen-Schmidt condensation protocol and analyzed.
