The present study compared the free and encapsulated photosensitizer hypocrellin B (HB) in terms of photophysical-chemical properties, cellular uptake, subcellular distribution, and phototoxicity. The hydrophobic HB was encapsulated into liposomes (HB@Lipo) or poly (lactic--glycolic acid) nanoparticles (HB@PLGA). Encapsulation into nanocarriers exerted no obvious influence on the photophysical-chemical properties of HB, including UV-visible absorbance, fluorescence spectra, singlet oxygen (O) production capacity, and photostability.

Colorectal cancer is the fourth most common malignant cancer worldwide, with limited treatment options for advanced cases. The natural compound hypocrellin B has been shown to inhibit tumor growth, but its effects and specific mechanisms of action in colorectal cancer remain unclear. Here, we explore the anti-tumor effect of hypocrellin B on human colorectal cancer cells and identify molecular targets.
