MC540 induced photosensitization of glioma & neuroblastoma cells.

Abstract
Binding and photodynamic action of merocyanine 540 (MC540) has been studied in glioma (U-87MG) and neuroblastoma (Neuro 2A) cells as a function of dye concentration, incubation time of cells with MC540 and growth phase of cells. In the plateau phase, U-87MG cells accumulated more MC540 as compared to exponentially growing cells, whereas in Neuro 2A cells the opposite effect was observed. Exponentially growing U-87MG cells were more photosensitive than plateau phase cells. However, the photosensitivity of Neuro 2A cells was not dependent on the growth phase. Thus, MC540 mediated photosensitization may be useful for photodynamic therapy of brain tumours.
