Study on the Crystallization Process of Labeled GL-7-ACA Acylase CA130 Complex 7β-bromoacetyl amino cephalosporanic acid (BA-7-ACA), an analog of glutaryl-7-amino cephalosporanic acid (GL-7-ACA), can inhibit and specifically alkylate GL-7-ACA acylase (CA130) from Pseudomonas sp. 130, forming a carbon-carbon bond between BA-7-ACA and the C-2 on indole ring of Trp-β4 residue of CA130.Here we reported that BA-7-ACA labeled CA130 (BA-C130) could self-catalyze the hydrolysis of BA-7-ACA during crystallization process. The hydrolysis was confirmed to be a reaction analogous to the one of GL-7-ACA by comparative MALDI-TOF (matrix-assisted laser desorption/ionization-time of flight) spectrometry analysis.

Besides, the series of synthetic compounds were tested for their capability to suppress growth of human hepatocellular carcinoma cell line Hep 3B and Hep G2, and myeloid leukemia cell line HL-60. The results showed compound 20, N-(2-amino- 3-nitrophenyl)cantharidinimide, exhibited more potent than others, but it was still less effective than cantharidin.

To study the applicable prospect of suicide gene on tumor therapy in clinic,we cloned the gene of D-amino acid oxidase and the gene of yeast cytosine deaminase.We hope to establish the transgenic mices of DAAO gene and YCD gene,and the two transgenic strain mices are valuable animal system for studying the biological characteristic of DAAO gene and YCD gene ,for studing the killing activity of DAAO/D-Ala and YCD/5-FC gene therapy systems on tumor.The D-amino acid oxidase gene derived from R.gracilis and it could oxidize D-amino acids. Hydrogen peroxide(H2O2) is a reactive oxygen species generated in the deamination of D-Ala catalyzed by DAAO.

为了探讨自杀基因在临床肿瘤治疗中的应用前景，建立自杀基因肿瘤治疗评价的动物模型，我们克隆了D-氨基酸氧化酶(D-amino acid oxidase，DAAO)基因和酵母菌胞嘧啶脱氨酶(yeast cytosine deaminase，YCD)基因，希望建立DAAO基因及YCD基因转基因小鼠，为研究DAAO及YCD基因的生物学特性、开发和评价DAAO／D-Ala及YCD／5-FC自杀基因系统进行肿瘤治疗建立良好的实验动物模型。

In this study we use the oligomers of amino ethylene series as matrix and introduce dithiocarbamate group to adsorb merely heavy metal ions. Because of its special structural characteristics , dithiocarbamate can combine with a great number of heavy metal ions to produce insoluble complex compound except for alkali metals and alkaline earth metals.
