Estudos quimiométricos da pheo formulada em pluronics ®: Ação fotodinâmica sobre Artemia salina

Abstract

The self-aggregation of pheophytin, a possible photosensitizer for Photodynamic Therapy, is solved by formulation in polymeric surfactant as P-123. The photosensitizer incorporation was found to be time dependent, exhibiting two steps: a partition at the micellar interface followed by an incorporation into the micelle core. The photodynamic effciency of the formulation was tested by the bioassays against Artemia salina. In order to evaluate how the experimental parameters: pheophytin concentration, P-123 percentage and illumination time infuenced the death of artemia, the factorial design 23 was chosen. The illumination time was found to be the main factor contributing to the mortality of artemia.
