In vitro inhibitory effect of aluminum phthalocyanine tetrasulfonate chloride against Leishmania (Viannia) Peruviana and Leishmania (Viannia) Braziliensis.

Objectives: To evaluate the in vitro photodynamic activity of aluminum phthalocyanine tetrasulfonate chloride (AlPcClS4) on promastigotes and amastigotes of Leishmania (Viannia) peruviana and Leishmania (Viannia) braziliensis.

Materials And Methods: The activity of photodynamic therapy using AlPcClS4 on Leishmania promastigote and amastigotes was determined by the Methyl Thiazole Tetrazolium (MTT) colorimetric method and quantitative PCR, respectively.

Results: Photodynamic treatment showed an inhibitory effect on promastigotes, particularly on Leishmania (V.
