Herein, we contribute to the development of environmentally friendly antifoulants by synthesizing eighteen isocyanides derived from α,α-disubstituted amino acids and evaluating their antifouling activity/toxicity against the cypris larvae of the Balanus amphitrite barnacle. Almost all isocyanides showed good antifouling activity without significant toxicity and exhibited EC50 values of 0.07 - 7.30
在此,我们通过合成十八种衍生自α,α-二取代
氨基酸的
异氰酸酯并评估其对Balanus辉石藤壶的塞浦路斯幼虫的防污活性/毒性,为开发环保型防污剂做出了贡献。暴露120小时后,几乎所有
异氰酸酯均显示出良好的防污活性,且无明显毒性,
EC50值为0.07-7.30μg/ mL。缬
氨酸,蛋
氨酸和苯丙
氨酸衍生的
异氰酸酯的
EC50值最低,在浓度低于30μg/ mL的情况下,实现了> 95%的鲤鱼幼虫沉降抑制,而未表现出明显的毒性。因此,所制备的
异氰酸酯应可用于进一步研究环境友好型防污剂。
