below their LC50, were analyzed at 48, 72 and 96 hours post fertilization, wherein the treated embryos manifested diverse visual phenotypes, such as big yolk sacs (3b, 3h, 3j), pericaldial edemas (3a, 3i) and red blood cells in the liver region (3b, 3l), in comparison to the morphology of the control embryos, the phenotypes could be associated with specific biological targets.
已经开发出一种有效且实用的方法,以高收率和高非对映选择性合成N-(四氢喹啉基-4)酰胺3a-1。该策略包括由铈(催化亚氨基Diels Alder反应多米诺型ABB' IV苯胺和之间)盐ñ -乙烯基酰胺用于测试它们的是四氢喹啉的12元文库的制备在体内对斑马鱼胚胎毒性。确定其LC 50值后,N-(8-甲氧基-2-甲基-四氢喹啉基-4)乙酰胺3k被确定为毒性最强的衍生物,LC 50低于95μM(24 mg L-1)。最后,在受精后48、72和96小时分析浓度低于其LC 50的诱导表型,其中处理过的胚表现出不同的视觉表型,例如大卵黄囊( 3b, 3h, 3j),梨状皮水肿( 3a, 3i)和肝脏区域( 3b, 3l)中的红细胞,与对照胚胎的形态相比,其表型可能与特定的生物学靶标有关。
