Abstract: Conjugates are provided which comprise a membrane permeable drug linked to a moiety that is not membrane permeable. Attachment of the moiety that is not membrane permeable prevents the drug from crossing cell membranes and entering cells. However, exposure to light either i) breaks the linkage, releasing the drug and allowing it to enter cells; or ii) converts the non-membrane permeable moiety to a membrane permeable form, allowing the entire conjugate to enter the cell, where the drug is released from the conjugate by cleavage. The membrane permeable drugs are thus delivered to cells at locations of interest, e.g. cancer cells in a tumor, in a temporally and spatially controlled manner.

Abstract: Near-infrared activatable fluorescent small molecules for the photodynamic treatment of cancer are provided. Methods of treatment include contacting a plurality of cells of the cancer with a near-infrared activatable fluorescent small molecule and directing a near-IR light to the molecule for an amount of time sufficient to induce release of the active platinum species and a reactive oxygen species.
