毒理性
识别与用途:四羧基苯基卟啉(TCPP)是一种深蓝色至紫色至黑色的粉末。TCPP是一种由可见光激活的强效光敏剂。它已被用作研究化学品、化学中间体和卟啉染料。它已在动物细胞模型中测试用于癌症的光动力治疗,并作为肺癌患者的非侵入性诊断分析。人体研究:无数据可用。动物研究:使用琼脂糖凝胶电泳研究了TCPP对ColE1超螺旋DNA的光敏化效应。在中性条件下观察到光诱导的单链和双链断裂形成。
IDENTIFICATION AND USE: Tetracarboxyphenylporphine (TCPP) is a dark blue to purple to black powder. TCPP is a potent photosensitizer activated by visible light. It has been used as a research chemical, chemical intermediate, and porphyrin dye. It has been tested for photodynamic therapy of cancer in animal cell models, and as a diagnostic noninvasive assay in lung cancer patients. HUMAN STUDIES: There are no data available. ANIMAL STUDIES: The photosensitizing effects of TCPP on ColE1 supercoiled DNA were studied using agarose gel electrophoresis. Photoinduced single- and double-strand breaks were observed to form under neutral conditions.
