Comparative Antiviral (HIV) Photoactivity of Metalized meso-Tetraphenylsulfonated Porphyrins

We have carried out the study of the photochemical properties of a series of synthetic mesotetraphenylsulfonated porphyrins (TPPMS4) bonded to several metal ions such as: Cu(II), Zn(II), Pd(II), Mn(II), Fe(III), Ni(II) and Co(II) for the optimization of their clinical applications as antiviral agents against the human immunodeficiency virus (HIV-1) as well as the study of the in vitro antiviral photoinactivation mechanisms with future application in blood sterilization. A selective inhibition has been determined in the viral growth (HIV-1) when this is irradiated in the presence of the complex TPPFeS4 and TPPMnS4 (photosensitizer-mediated Type I reaction) as well as in the 1O2- mediated (Type II reaction) in the presence of TPPPdS4 and TPPZnS4, remaining cellular viability unaltered in each case.
