A series of novel zinc(II) phthalocyanines mono-substituted with a 1,3-bis(dimethylamino)-2-propoxy group at the alpha- or beta-position, and the corresponding di-N-methylated derivatives, have been synthesized. All these compounds can generate singlet oxygen effectively and exhibit high in vitrophotodynamicactivities toward HT29 human colorectal carcinoma cells with IC(50) values down to 0.08microM
