Abstract
Deuteroporphyrin IX derivatives are prospective PDT porphyrin photosensitizers (PS). The photodynamic effects of 6 new amphiphilic deuteroporphyrin derivatives with different hydrophobicity, as well as effects of known photosensitizers Photoheme and Photosens (used for comparison) on the firing of isolated crayfish mechanoreceptor neuron have been studied. After 30 min photosensitization, neurons were irradiated with He-Ne laser (632.8 nm, 0.3 W/cm2), and changes in neuron firing frequency were recorded. It has been shown that neuron firing is very sensitive to photodynamic impact and can serve as a sensitive indicator of cell photodamage.
