Introduction: Toxoplasmosis, a zoonotic infection caused by the apicomplexan parasite , affects a significant portion of the global human population. This condition, particularly dangerous for pregnant women and immunocompromised individuals, currently lacks effective treatment options.
Methods: Eighteen coumarin-based derivatives were synthesized, comprising coumarin-chalcone hybrids (5a-i) and coumarin-pyrazoline hybrids (6a-i). Cytotoxicity was evaluated using L929 mouse fibroblasts and Hs27 human fibroblasts. Anti- activity was assessed, and molecular docking studies were performed to predict binding modes with TgCDPK1.
Results: Pyrazoline hybrids (6a-i) showed lower toxicity than chalcone-bearing coumarins (5a-i), with CC values exceeding the highest tested concentration (500 µg/mL) for most compounds. The synthesized molecules demonstrated strong anti- activity, with IC values ranging from 0.66 µg/mL to 9.05 µg/mL. Molecular docking studies provided insights into potential binding mechanisms.
Conclusion: This study highlights the potential of coumarin-based hybrids as anti- agents. The findings should contribute to the growing arsenal of small molecules against and underscore the value of molecular hybridization in drug design. Further studies to elucidate these compounds' mechanism of action and in vivo efficacy are warranted to fully realize their potential as anti-parasitic agents.
