合成了两个混合配体配合物[Pd(phen)(trp)]Cl·5H_2O （1） 和 [Pd(5- NO_2phen)(trp)]Cl·5H_2O （2）（其中phen = 1，10-phenanthroline，5- NO_2phen = 5-nitro-1,10-phenanthroline，trp = L-tryptophan）。配合物对肺 腺癌细胞AGZY-83a均具有一定的杀伤活性，IC_(50)值分别为158.5 μg/mL和大于 293.0 μg/mL。荧光法测定配合物与鱼精DNA的结合常数（K）分别为6.36 * 10~6 和3.64 * 10~6。荧光光谱、紫外可见光谱和粘度法证实配合物主要以插入方式与 DNA结合。

[Pd(phen)(trp)]Cl·5H_2O and [Pd(5-NO_2phen)(trp)]Cl·5H_2O have been synthesized (phen = 1,10-phenanthroline, 5-NO_2phen = 5-nitro-1, 10-phenanthroline, trp = L-tryptophan). The compounds display anti- cancer activity to lung cancer cell AGZY-83a with IC_(50) of 158.5 μ g/mL and >293.0% μg/mL respectively. The binding constants of the compounds with sperm DNA are determined by fluorescence analysis, which are 6.36 * 10~6 and 3.64 * 10~6 respectively. Intercalation of the compounds with DNA can be demonstrated by fluorescence spectra, UV- spectra and viscometer.
