Screening and Evaluation of Antifouling Active Cardiac Glycoside-related Compounds [PDF]

open access: yes, 2016
海洋生物污损给人类海洋活动带来了巨大的危害,一系列高毒、难降解的海洋防污剂在使用过程中对海洋环境造成了极大的破坏,已被禁用或限用,从而迫切需要开发出新型绿色环境友好型海洋防污涂料。其中筛选以天然防污产物为核心的防污剂,是研制新型绿色环境友好型海洋防污涂料的基础。本文立足于天然防污产物的商业化在量上和成本上受到限制等现状,从资源量较大、成本较低的陆地植物中进行防污活性化合物的提取和筛选,结合实验室内防污活性检测和海区测试结果共同评估防污效果,另外通过进行强心苷类化合物防污活性的构效分析与毒性研究 ...
