A new chromophore, 2-(4-nitrophenyl)benzofuran (NPBF), was designed for two-photon (TP) uncaging using near-IR light. The TP absorption (TPA) cross-sections of the newly designed NPBF chromophore were determined to be 18 GM at 720 nm and 54 GM at 740 nm in DMSO. The TP uncaging reaction of a caged benzoate with the NPBF chromophore quantitatively produced benzoic acid with an efficiency (δu) of ~5.0 GM at 740 nm. The TP fragmentation of an EGTA unit was observed with δu = 16 GM. This behavior makes the new chromophore a promising TP photoremovable protecting group for physiological studies.

Rapamycin-induced dimerization of FKBP and FRB is the most commonly utilized chemically induced protein dimerization system. It has been extensively used to conditionally control protein localization, split-enzyme activity, and protein-protein interactions in general by simply fusing FKBP and FRB to proteins of interest. We have developed a new aminonitrobiphenylethyl caging group and applied it to the generation of a caged rapamycin analog that can be photoactivated using blue light. Importantly, the caged rapamycin analog shows minimal background activity with regard to protein dimerization and can be directly interfaced with a wide range of established (and often commercially available) FKBP/FRB systems. We have successfully demonstrated its applicability to the optical control of enzymatic function, protein stability, and protein subcellular localization. Further, we also showcased its applicability toward optical regulation of cell signaling, specifically mTOR signaling, in cells and aquatic embryos.

We have designed a nitroaromatic photochemical protecting group that absorbs visible light in the violet-blue range. The chromophore is a dinitro derivative of bisstyrylthiophene (or BIST) that absorbs light very effectively (ε440 = 66,000 M-1 cm-1 and two-photon cross section of 350 GM at 775 nm). We developed a "caged calcium" molecule by conjugation of BIST to a Ca2+ chelator that upon laser flash photolysis rapidly releases Ca2+ in 2+, was delivered into acutely isolated mouse cardiac myocytes, where either one- and two-photon uncaging of Ca2+ induced highly local or cell-wide physiological Ca2+ signaling events.
