Novel azo compounds and their bioconjugates for phototherapy and/or photodiagnosis of tumors and other lesions. The azo derivatives of the present invention are designed to absorb at the low-energy ultraviolet, visible, or near-infrared (NIR) region of the electromagnetic spectrum. The phototherapeutic effect is caused by direct interaction of free radicals, the reactive intermediate produced upon photoexcitation of the azo compound, with the tissue of interest.
小说偶氮化合物及其生物共轭物用于肿瘤和其他病变的光治疗和/或光诊断。本发明的偶氮衍生物设计为在电磁波谱的低能紫外线、可见光或近红外(NIR)区域吸收。光治疗效应是由自由基直接与感兴趣的组织相互作用产生的,这是在偶氮化合物光激发时产生的反应中间体。
