Currently activities involve (1) Investigation of dye-DNA interaction by using spectroscopic methods to probe the binding sites between chromophore and DNA and to identify various DNA conformational structures, particularly the telomeric DNA;(2) Investigation of the structure-activity correlation of anti-telomerase agents;(3) Design and synthesis new compounds for antitumor agents and fluorescence biomarkers;(4) Monitoring the folding and unfolding of quadruplex structure, tracing the pathway of drug delivery and probing drug-target interaction by using single molecule microscopy and spectroscopy.

目前 的研究重点分别是(1)利用光谱方法探讨探针分子与DNA的交互作用，特别是作用位置与结构变化；(2)研究抗端粒酵素作用分子之结构与生物活性之关系；(3)设计及合成抗肿瘤药剂或萤光生物标记；(4)建立单分子萤光光谱与影像技术，研究 DNA的多变型结构之变化机制，监测药物输送的路径过程及其在细胞中与标的物的作用。

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。

In order to overcome the problem of multidrug resistance in human epidemic carcinomata anti-adriamycin cells (KB-A-1), the antisense and antigene oligonucleotides were used to investigate their effectiveness on inhibiting the mdr1 gene expression. The effectiveness of antisense or antigene oligonucleotide on inhibiting the multidrug resistance was detected by MTT colometric assay and ELISA.
