Application

Protein degrader building block Thalidomide-Photoswitch3-NH2 hydrochloride enables the synthesis of PHOtochemically TArgeting Chimeras (PHOTACs), or photoswitchable proteolysis-targeting chimeras (PROTACs) that can be reversibly activated with different wavelengths of light. Developed in the Trauner and Pagano labs, PHOTACs are inactive in the dark but are activated to the cis isomer via irradiation at 390 nm and reversibly deactivated at wavelengths above 450 nm. As described in Reynders et al, this conjugate was used to prepare PHOTAC-I-10 and PHOTAC-II-6 and contains a Cereblon (CRBN)-recruiting ligand, an azobenzene photoswitchable crosslinker, and pendant amine for reactivity with an acid on the target warhead. Light-mediated control of the resulting PHOTAC affords advanced temporal and spatial control of targeted protein degradation.

Suggested wavelengths for photoswitching:
  • Switch to cis isomer: 390 nm (380-400 nm)
  • Switch to trans isomer (thermally more stable isomer): >450 nm
Low-intensity light needed for photoactivation is not cytotoxic.

Trends in cell biology, 30(10), 749-751 (2020-08-29)
PROteolysis-TArgeting Chimeras (PROTACs) have been developed for targeting specific protein destruction. Two recent studies in Science Advances by Liu et al. and Reynders et al. reported a novel technology, PHOtochemically TArgeting Chimeras (PHOTACs) or opto-PROTAC, which is light-induced control of

PROTACs (PROteolysis TArgeting Chimeras) are bifunctional molecules that target proteins for ubiquitylation by an E3 ligase complex and subsequent degradation by the proteasome. They have emerged as powerful tools to control the levels of specific cellular proteins. We now introduce
