Area of Science:

  • Medicinal Chemistry
  • Parasitology
  • Drug Discovery

Background:

  • Malaria remains a significant global health threat, particularly due to the emergence of drug-resistant Plasmodium falciparum strains.
  • Developing novel antimalarial agents is crucial to combatting this deadly disease.

Purpose of the Study:

  • To synthesize and evaluate novel compounds for potent activity against multi-drug-resistant Plasmodium falciparum.
  • To assess the safety and pharmacokinetic properties of these new antimalarial candidates.

Main Methods:

  • Synthesis of a series of novel chemical compounds.
  • In vitro testing of antimalarial activity against Plasmodium falciparum Dd2 strain.
  • Cytotoxicity assays using human foreskin fibroblasts.
  • Evaluation of lipophilicity (logD) and metabolic stability using human and murine hepatocytes.
