Antimalarial activity of borrelidin and fumagilin in Plasmodium berghei-infected mice

Background:
Malaria remains a significant global health burden, with drug resistance posing a major challenge to its control. The emergence of resistance to antimalarial drugs represents a critical issue in malaria management, as it heightens the likelihood of morbidity and mortality associated with the disease. There is an urgent requirement for a novel candidate drug with a distinct mechanism of action.
Aim:
In light of the ongoing challenges in malaria management, particularly the emergence of drug resistance, this study aimed to investigate the efficacy of a novel combination therapy of borrelidin and fumagilin against Plasmodium berghei infection on Swiss Webster mice. The findings of this study could contribute to developing new and effective antimalarial treatments.
Methods:
This study employed a unique approach, using Swiss Webster mice aged 6–8 weeks and dividing them into five groups, each with five mice. The therapeutic efficacy of the combination treatment was evaluated through a comprehensive assessment of parasitemia levels, survival rates, and histological changes in the liver and spleen. This rigorous methodology ensures the reliability and validity of our findings.
Results:
The combination of borrelidin and fumagilin led to the lowest parasitemia at 5%, contrasting with the control group reaching 15%. Moreover, the combination group exhibited the highest inhibition rate of 69.6% on day nine post-infection. Histopathological alterations were limited to sinusoid dilation, hepatocyte ballooning, and the presence of hemozoin.
Conclusion:
These findings suggest that the combination of borrelidin and fumagilin holds promise as a potential antimalarial therapy.
