Abstract: Activity of three photosensitizing phthalocyanine derivatives was tested for photodynamic inactivation towards two coated and two non-enveloped viruses – bovine viral diarrhea virus (BVDV), influenza virus A(H3N2), poliovirus type 1 (PV-1) and human adenovirus type 5 (HAdV5). In the case of coated viruses, a combination of virucidal and irradiation effects was registered by octa-methylpyridyloxy-substituted Ga phthalocyanine (Ga8) toward BVDV, whereas tetra-methylpyridyloxy-substituted Ga phthalocyanine (Ga4) revealed a marked photoinactivation only. No such effect was observed towards influenza A virus. In contrast, the photoinactivating potential of Ga4 and Ga8 marked very high values on naked viruses, especially on HAdV5, at which both the virucidal as well as the irradiation effects became combined.
