Targeting Leishmaniasis with Nitrovinyl Derivatives: Synthesis, In Vitro Assessment, and Computational Exploration

Area of Science:

• Medicinal Chemistry
• Parasitology
• Computational Biology

Background:

• Leishmaniasis, caused by Leishmania parasites, affects over a million people globally, with current treatments lacking optimal efficacy.
• The development of novel therapeutic agents is crucial to combat the significant disability and mortality associated with leishmaniasis.

Purpose of the Study:

• To design, synthesize, and evaluate novel nitrovinyl pharmacophore derivatives against Leishmania major.
• To investigate the in vitro and in silico efficacy of these compounds, including their synergistic potential with existing drugs.

Main Methods:

• Synthesis and purification of nineteen nitrovinyl derivatives.
• In vitro assays to assess inhibition of Leishmania major amastigotes and promastigotes.
• In silico molecular docking studies to identify potential drug targets.

Main Results:

• Compounds 10, 15, and 18 exhibited superior amastigote inhibition compared to meglumine antimonate (MA).
• Several compounds showed enhanced inhibitory effects against promastigotes and synergistic activity with MA.
• Molecular docking identified SAM-dependent methyltransferase (1XTP) and Prostaglandin F synthase (4G5D) as likely targets.

Conclusions:

• The synthesized nitrovinyl compounds demonstrate significant potential as anti-leishmanial agents.
• These compounds exhibit promising synergistic effects with meglumine antimonate, suggesting improved therapeutic strategies.
• Further research into these compounds could lead to more effective treatments for leishmaniasis.
