Novel azo compounds and bioconjugates thereof for phototherapy and / or photodiagnosis of tumors and other lesions. The azo derivatives of the present invention are designed to absorb in the low energy ultraviolet, visible, near infrared (NIR) region of the electromagnetic spectrum. The phototherapy effect is due to a direct interaction between a free radical, which is a reactive intermediate produced upon photoexcitation of an azo compound, and a target tissue. |
