Two new conjugates of pyropheophorbide a with testosterone and dihydrotestosterone: 173[2-(17β-hydroxy-3-oxopregn-4-en-21-oylamido)ethylamido]pyropheophorbide a (10) and 173[2-(17β-hydroxy-3-oxopregnan-21-oylamido)ethyl-amido]pyropheophorbide a (11) were synthesized. IC50 for conjugates 10 and 11 at 96 h incubation in LNCaP and PC-3 prostate carcinoma cells were 1.4 μM and 3.3 μM for compound 10, and 4.5 μM and 6.1 μM for compound 11, respectively. Irradiation with light at wavelength of 660 nm increased toxicity of the conjugates.
