Silicon Phthalocyanine 4, formerly known as Pc-4, is a drug potentially for the treatment of cutaneous neoplasms. Photoirradiation of the silicon phthalocyanine 4 photosensitizer with red light generates singlet oxygen and other reactive oxygen species to induce cell death. Pc 4 is absorbed into the epidermis in as little as 1 hour and the absorption increased with increasing time and dose. Silicon phthalocyanine 4 can be effectively delivered into human skin via topical application. References: Dimaano ML, Rozario C, Nerandzic MM, Donskey CJ, Lam M, Baron ED.
