Abstract

A series of chlorin p₆ derivatives modified at the 3- position of the macrocycle were prepared on the base of purpurin 18. The chlorins obtained have intense absorption maxima in the range of 665 - 698 nm and posses good water- solubility. Studying photodynamic activity of these sensitizers in vitro showed that the most effective was 3- devinyl-3-formylchlorin p₆. This sensitizer demonstrated also enhanced in vivo affinity to the tumor tissue in comparison to other chlorins, which correlated with the pH values of aqueous solutions of sensitizers studied.
