The aim of this study was to investigate the in vivo toxicities of some novel synthetic chalcones. Chalcone and four chalcone analogues 1a–d were evaluated using zebrafish embryos following antibody staining to visualize their morphological changes and muscle fiber alignment. Results showed that embryos treated with 3'-hydroxychalcone (compound 1b) displayed a high percentage of muscle defects (96.6%), especially myofibril misalignment. Ultrastructural analysis revealed that compound 1b-treated embryos displayed many muscle defect phenotypes, including breakage and collapse of myofibrils, reduced cell numbers, and disorganized thick (myosin) and thin (actin) filaments. Taken together, our results provide in vivo evidence of the myotoxic effects of the synthesized chalcone analogues on developing zebrafish embryos.
本研究旨在调查一些新型合成查耳酮的体内毒性。研究人员使用斑马鱼胚胎对查尔酮和四种查尔酮类似物 1a-d 进行了评估,通过抗体染色观察它们的形态变化和肌纤维排列。结果表明,用 3'-hydroxy chalcone(化合物 1b)处理的胚胎显示出很高比例的肌肉缺陷(96.6%),尤其是肌纤维错位。超微结构分析表明,经化合物 1b 处理的胚胎显示出许多肌肉缺陷表型,包括肌原纤维断裂和塌陷、细胞数量减少以及粗(肌球蛋白)丝和细(肌动蛋白)丝紊乱。综上所述,我们的研究结果为合成的查尔酮类似物对发育中的斑马鱼胚胎的肌毒性作用提供了体内证据。
