    • A compound having preferential localization in tumor tissue relative to normal tissue, a preferential electromagnetic absorption at a wavelength between about 660 and 900 nm, and a fluorescence at a wavelength shifted from the preferential absorption by at least +30 nm and preferably at least +50 nm. The compound further preferably destroys tumor tissue in which it is absorbed when exposed to light at its preferential absorption wavelength. In a preferred embodiment of the invention, the compound is a conjugate of a tumor avid tetrapyrrole compound with a fluorescent dye, and more preferably the fluorescent dye is an indocyanine dye such as indocyanine green. The tumor avid tetrapyrrole compound is preferably a porphyrin derivative selected from the group consisting of chlorins, bacteriochlorins, purpurins and derivatives thereof.
    • 相对于正常组织在肿瘤组织中优先定位的化合物,在约660和900nm之间的波长处的优先电磁吸收以及波长从优选吸收偏移至少±30nm,优选至少+50nm的荧光 nm。 该化合物进一步优选地破坏在其优先吸收波长下暴露于光时被吸收的肿瘤组织。 在本发明的一个优选实施方案中,化合物是肿瘤病毒四吡咯化合物与荧光染料的缀合物,更优选荧光染料是吲哚菁染料,如吲哚菁绿。 肿瘤病毒四吡咯化合物优选为选自二卟啉,细菌二氢卟酚,紫草素及其衍生物的卟啉衍生物。
