The present description includes compounds that act as degraders of a target protein, wherein degradation is independent of the class of the target protein or its localization. In certain embodiments, the description includes a compound comprising a protein degradation moiety covalently bound to a linker, wherein the ClogP of the compound is equal to or higher than 1.5. The target protein contemplated within the description comprises an androgen receptor. Compounds of the present description may be used to treat disease states wherein protein degradation is a viable therapeutic approach, such as cancer or any sort of oxidative stress disease state.

ene-derived two-photon fluorescent Ca2+ probes (ACa1-ACa3) are reported. They can be excited by a 780 nm laser beam, show 23-50-fold enhancement in one- and two-photon excited fluorescence in response to Ca2+, emit fourfold stronger two-photon excited fluorescence than Oregon Green 488 BAPTA-1 upon complexation with Ca2+, and can selectively detect intracellularfree Ca2+ ions in live cells and living

A two-photon probe for real-time monitoring of intracellular magnesium ions is provided. Specifically, the two-photon probe is represented by Formula 1:
wherein R is H or CH2OCOCH3.
The two-photon probe is very suitable for real-time imaging of intracellular magnesium ions. The two-photon probe shows 17-fold two-photon excited fluorescence enhancement in response to Mg2+, which is 7-fold stronger than commercial probes, thus enabling staining of cells in a greatly reduced amount. In addition, the two-photon probe has a sufficiently low molecular weight to stain cells and is very suitable for monitoring Mg2+ ions present in the deep tissue. Furthermore, the two-photon probe can be effectively used for the quantitative as well as qualitative detection of intracellular magnesium ions. Further provided are a method for preparing the two-photon probe and a method for real-time monitoring of intracellular magnesium ions using the two-photon probe.

two‐photon probes are needed. Herein, we report a new two‐photon fluorescentprobe (ANi2) that can be excited by 750 nm femtosecond pulses and detect Ni2+ ions in fresh fishorgans at 90–175 μm depth without interference from the pH value or from other biologically relevant species through the use of TPM. TPM images of fishorgans labeled with ANi2 revealed that Ni2+ ions accumulate in fishorgans in the
