Evaluation of the anti-toxoplasma gondii activity of hederagenin in vitro and in vivo

Abstract

Toxoplasma gondii infection is widespread worldwide, not only posing a serious threat to human food safety and animal husbandry, but also endangering human health. The selectivity index was employed to measure anti-T. gondii activity. Hederagenin (HE) exhibited potent anti-T. gondii activity and low cytotoxicity. For this reason, HE was selected for in vivo experiments. HE showed 64.8%± 13.1% inhibition for peritoneal tachyzoites in mice, higher than spiramycin 56.8%± 6.0%. Biochemical parameters such as alanine aminotransferase, aspartate aminotransferase, glutathione, and malondialdehyde, illustrated that HE was a good inhibitor of T. gondii in vivo. This compound was also effective in reliev-ing T. gondii-induced liver damage. Collectively, it was demonstrated that HE had potential as an anti-T. gondii agent.
