Near-infrared light controlled protein degradation by photo-caged lenalidomide and pomalidomide

Immunomodulatory drugs (e.g. thalidomide, lenalidomide and pomalidomide) have been proven highly successful in clinical treatment of multiple myeloma. However, systematic degradation of zinc finger transcriptional factors induced by these drugs could lead to severe systematic toxicity in patients. Previous reports of NVOC caged pomalidomide attempted to regulate its activity using UVA irradiation, but their application was limited by high cytotoxicity and low tissue penetration. Here, we reported red-shifted BODIPY caged lenalidomide and pomalidomide that enabled red-light controlled protein degradation with spatiotemporal precision.
