 AB    We have investigated the photodynamic activity of a new chlorin-type
       photosensitizer on a reference human immunodeficiency virus type 1
       (HIV-1) strain, two wild-type HIV-1 isolates and two drug-resistant
       HIV-1 isolates. This chlorin was highly effective for the inactivation
       of free viruses, as assessed by two different quantitative cell culture
       assays. In the absence of blood components, all the HIV strains,
       including wild-type and drug-resistant mutant isolates, were totally
       inactivated using 30 micrograms ml-1 of chlorin and 0.75 J cm-2 of 661
       nm light. Successful killing of HIV-1 strains in either plasma or whole
       blood was also obtained by increasing the chlorin concentration
       moderately. Our results demonstrate the antiviral efficiency of this
       chlorin, suggesting the potential application of dye-sensitized
       photoirradiation to decontaminate blood products.
