| 摘 要： | 本研究旨在筛选具有抗弓形虫活性的萜类化合物，并进行体外活性评价。对26个萜类化合物进行体外抗弓形虫增殖作用的筛选，采用CCK-8法确定活性化合物对Vero细胞的毒性和安全浓度，Giemsa染色进一步确定对弓形虫的活性，通过细胞免疫荧光、Giemsa染色和生物化学发光法评价活性化合物对弓形虫的体外活性。结果表明，26个萜类化合物中，桧烯对弓形虫有显著的活性，桧烯对RH-2F的IC50为90.76 μg·mL-1，Giemsa染色和细胞免疫荧光的结果表明，桧烯对细胞内的两种弓形虫虫株都有显著的抗增殖作用，并且对弓形虫的入侵有极显著的抑制作用（P<0.001）。综上表明，桧烯对弓形虫的入侵和细胞内增殖具有显著的抑制作用，可作为潜在的抗弓形虫先导化合物。

| Abstract: | This study aimed at screening terpenoids with anti-Toxoplasma gondii activity and evaluating their activity in vitro. The activity of 26 terpenoids against Toxoplasma gondii (T. gondii) in vitro was screened. The toxicity and safe concentration of these active compounds to Vero cells were determined by CCK-8 kit. The activity against T. gondii was further identified by Giemsa staining. The activity of the active compounds against T. gondii in vitro was evaluated by cell immunofluorescence, Giemsa staining and biochemical luminescence method. The results showed that among the 26 terpenoids, sabinene had a significant activity against T. gondii. The IC50 of sabinene to RH-2F was 90.76 μg·mL-1. The results of Giemsa staining and cellular immunofluorescence showed that sabinene had significant anti-proliferative effect on two intracellular strains of T. gondii and had a very significant inhibitory effect on the invasion of T. gondii (P<0.001). It has been found that sabinene had a significant inhibitory effect on the invasion and intracellular proliferation of T. gondii, and can be used as a potential lead compound against T. gondii. |
