OBJECTIVE: To induce the rat model of polycyst with renal tumor and investigate the expression of 8-OHdG in the kidney tissues. METHODS: The rat model of polycyst with renal tumor, similar to human acquired cystic disease of the kidney (ACDK), was induced by oral administration of 2-amino-4, 5-diphenylthiazole (DPT) and N-nitrosomorpholine (NNM). Immunohistochemical method (LSAB) was used to assay the expression of 8-hydroxydeoxyguanosine (8-OHdG) in the rat kidney tissue. RESULTS: Three of 10 rats in the NNM group had renal solid adenomatous lesions. Bilateral polycysts were observed in all 9 rats of the DPT/NNM group. Seven of the 9 rats had cystic multistage renal tumor. In the DPT/NNM group, 4 rats had cystic adenomatous lesions, but none in the other groups showed this lesion. In the model, adenomatous lesions derived from polycysts in the rats were closely consistent to human ACDK in morphology. The significant expression of 8-OHdG was found on renal tubular cell, cystic epithelial cell, stromal cell and tumor cell in all rats of the NNM and DPT/NNM group. CONCLUSION: A rat model of polycysts with renal tumor, similar to human ACDK, induced by DPT and NNM provides evidences for further study on pathogenic mechanism in human ACDK with renal cell carcinoma. The expression of 8-OHdG, a DNA damage marker, in the renal tissues of rat model might help to explain the mechanism of cysticogenesis and carcinogenesis in human ACDK. In the experiment, the researchers used many compounds, for example, 4,5-Diphenylthiazol-2-amine (cas: 6318-74-7Application of 6318-74-7).
4,5-Diphenylthiazol-2-amine (cas: 6318-74-7) belongs to thiazole derivatives. The higher aromaticity of thiazole is due to delocalization of a lone pair of sulfur electrons across the ring, which is evidenced by chemical shifts of ring hydrogen at δ 7.27 and 8.77 ppm (C2 and C4), indicating diamagnetic ring current. Various laboratory methods exist for the organic synthesis of thiazoles. Prominent is the Hantzsch thiazole synthesis is a reaction between haloketones and thioamides.Application of 6318-74-7
