Provided herein are compositions containing photoactivatable caged tamoxifen and tamoxifen derivative molecules. Also provided are kits containing one of these compositions and a light source. Also provided are methods of optically inducing nuclear translocation of a fusion protein containing a mammalian estrogen receptor ligand binding domain in a eukaryotic cell and methods of optically inducing recombination in a eukaryotic cell that include contacting a eukaryotic cell with at least one of these compositions. Also provided are methods of treating breast cancer in a subject that include administering a photoactivatable caged tamoxifen or tamoxifen derivative molecule to a subject having breast cancer.

Many cell‐penetrating peptides (CPPs) fold at cell surfaces, adopting α‐ or β‐structure that enable their intracellular transport. However, the same structural folds that facilitate cellular entry can also elicit potent membrane‐lytic activity, limiting their use in delivery applications. Further, a distinct CPP can enter cells through many mechanisms, often leading to endosomal entrapment. Herein
