Abstract

Graphic abstract

A novel cell-permeable compound, CypH-1, that is non-fluorescent at neutral pH, but fluoresces under mildly acidic conditions with a near infrared maximum emission wavelength was designed for the detection of tumors in the clinical setting. The potential of CypH-1 in ovarian cancer imaging was demonstrated using a murine model. The intraperitoneally administered CypH-1 results in a robust fluorescence signal of discrete neoplastic lesions with millimeter range resolution within few hours. Moreover, fluorescence signal is strikingly enhanced at peripheral regions of tumors at the microscopic level suggesting a sharp physiological difference at the tumor/normal tissue interface. This robust acid-activated imaging agent is expected to have significant impact in broad surgical and diagnostic applications.

Keywords: fluorogenic dye, pH indicator, tumor microenvironment, acidic, ovarian cancer.
