Studies on aromatic compounds: inhibition of calpain I by biphenyl derivatives and peptide-biphenyl hybrids

Bioorganic & Medicinal Chemistry Letters, 2004
With the objective to understand structural features responsible for the biological activity, novel nonelectrophilic biphenyl derivatives and peptide-biphenyl hybrids have been synthesized and evaluated as calpain I inhibitors. The preliminary results indicate that the presence of additional aromatic rings (besides the biphenyl system) makes these ...

Governing the emissive properties of 4-aminobiphenyl-2-pyrimidine push–pull systems via the restricted torsion of N,N-disubstituted amino groups

Frontiers in Chemistry, 2023
Donor–acceptor-substituted biphenyl derivatives are particularly interesting model compounds, which exhibit intramolecular charge transfer because of the extent of charge transfer between both substituents.

Autochthonous bioaugmentation with non-direct degraders: A new strategy to enhance wastewater bioremediation performance

Environment International, 2020
Autochthonous bioaugmentation (ABA) strategies are primarily carried out using a single, highly efficient type of bacteria that is capable of directly degrading the target compound. However, no studies have examined the use of non-direct degraders (NDDs),
