New Crown Spirobenzopyrans as Light- and Ion-Responsive Dual-Mode Signal Transducers
摘要:
A new class of crown spirobenzopyrans were designed and synthesized. The crown spirobenzopyrans showed thermally irreversible photochromism only in the presence of alkali-metal cations accompanying cation-selective coloring efficiency. Thus, the new crown spirobenzopyrans could transmit information of two different simultaneous stimuli (ion and photon) to changes in their optical properties. The dual-mode signal transducer molecules developed here can be considered to perform ''AND'' gate type signal transduction based on photochromism of artificial receptors. Molecular recognition abilities and photochromic properties of the new crown spirobenzopyrans were characterized by use of NMR and FAB mass spectroscopies.

The present disclosure relates to bifunctional compounds, which find utility as modulators of SMARCA2 or BRM (target protein). In particular, the present disclosure is directed to bifunctional compounds, which contain on one end a ligand that binds to the Von Hippel-Lindau E3 ubiquitin ligase, and on the other end a moiety which binds the target protein, such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of target protein. The present disclosure exhibits a broad range of pharmacological activities associated with degradation/inhibition of target protein. Diseases or disorders that result from aggregation or accumulation of the target protein are treated or prevented with compounds and compositions of the present disclosure.

with enhanced water solubility, that is 3 and 4, derived from the previously described CTV scaffold derivative 2 are described here. These scaffolds 2–4 enabled a sequential introduction of three different complementarity determining region (CDR) mimics via Cu(I)-catalysed azide–alkyne cycloaddition towards medium-sized protein mimics denoted as “synthetic antibodies”. The highly optimised sequential

stereochemistry of the hydroalumination was established by the decomposition of the intermediate organometallic complex with deuterium oxide and iodine. The hydride ion was shown to attack the internal carbon atom of acetylene group. The decomposition of the intermediate organometallic complex with deuterium oxide results in a mixture of the geometric isomers of 2-[2-propen-1-yloxy]ethanold1 III. In the

Molecular Recognition Abilities of a New Class of Water-Soluble Cyclophanes Capable of Encompassing a Neutral Cavity
We developed a newclass of water-soluble cyclophanes, pyrenophanes, capable of encompassing a neutral cavity, in which the hydrophobic area is constructed by aligning two flat polynuclear aromatic rings parallel at an appropriate space that could interpose just one layer of aromatic plane. The height, depth, and width of the cavity in an open conformation of the pyrenophane are 0.46, 0.95, and 1.31

The present disclosure relates to bifunctional compounds, which can be used as modulators of targeted ubiquitination. In particular, the present disclosure is directed to compounds which contain on one end a VHL ligand moiety, which binds to the VHL E3 ubiquitin ligase, and on the other end a moiety that binds a target protein such that degradation of the target protein/polypeptide is effectuated. Also disclosed are VHL ligands.
