The rules of photo bioactivities are: Without illumination, the tested xanthene derivatives showed almost the same level of inherent toxicity to the same organism, which showed the inherent toxicity of xanthene derivatives were primarily dependent on the structure of parent molecule. Upon illumination, the photosensitizers showed obvious phototoxicity to all organisms. The xanthene derivatives showed stronger phototoxicity to Gram-positive bacteria. With the increasing number of halogen substituents, the singlet oxygen yields increased and the phototoxic activity increased too.

呫吨类化合物的生物活性的变化规律为：未经光照的条件下，呫吨类化合物的对同种待测微生物的固有生物活性基本相同，说明固有毒性可能主要决定于化合物分子的母核结构，其卤素取代基团对其影响较小；经实验光源照射下，所测MLC值明显低于未经光照条件下的值，表明呫吨类化合物对三种微生物的光敏活性明显强于对其相应的固有活性；呫吨类化合物对革兰氏阳性菌能发挥较大的光敏活性。

Emphasis: Aminolysis method of hydroxyl on alcohol, addition amination of epoxy alkyl, aminolysis of aliphatics haloid.
