Abstract

The present invention relates to compounds which are perylenequinone derivatives, their stereoisomers and atropisomers. These compounds can be particularly useful as photosensitizers or sononsensitizers in photodynamic or sonodynamic therapy. The invention also relates to various methods for using these compounds in photodynamic and/or sonodynamic therapy. The compounds also are useful as therapeutic agents for treating various hyperproliferative disorders.
