PHOTOPROXIMITY PROFILING OF PROTEIN-PROTEIN INTERACTIONS IN CELLS

, (2021/04/01)
Photoactive probes and probe systems for detecting biological interactions are described. The photoactive probes include probes that combine both photocleavable and photoreactive moieties. The photoactive probe systems can include a first probe comprising a photocatalytic group and a second probe comprising a group that can act as a substrate for the reaction catalyzed by the photocatalytic group. The probes and probe systems can also include groups that can specifically bind to a binding partner on a biological entity of interest and a detectable group or a precursor thereof. The probes and probe systems can detect spatiotemporal interactions of proteins or cells. In some embodiments, the interactions can be detected in live cells. Also described are methods of detecting the biological interactions.
1,4-Dihydro-2,3-quinoxalinediones as potential flavin metabolites and excitatory amino acid receptor ligands. Part 1: Synthesis and pharmacological evaluation of the benzylic oxidation series of 1,4-dihydro-6,7-dimethyl-2,3- quinoxalinedione

A series of five 6,7-disubstituted 1,4-dihydro-2,3-quinoxalinediones was prepared, two of which are known microbial flavin metabolites and three of which are potential flavin metabolites. Four of the five compounds inhibited specific binding of [3H]-amino-3-hydroxy-5-methyl-4-isoxazolepropanoic acid ([3H]AMPA), [3H]kainic acid, and [3H]6-cyano-1,4-dihydro-7-nitro-2,3- quinoxalinedione ([3H]CNQX) in rat brain homogenate fractions, with IC50 values in the low micromolar range (the fifth compound competed only with [3H]CNQX). Two of the compounds were moderately potent AMPA antagonists in an in vitro functional test.
