A methodology to detect peroxidase activity in cladodes waste extracts was performed and then used towards phenolic compounds. The extracts were able to dimerize three different molecules. Dimeric compounds were produced with yields ranging from 11% to 55%. The influence of HO concentration was also tested, finding better yields when the peroxide-to-substrate ratio was 1:1. Some water-miscible solvents were used trying to increase overall yields, but no-significant positive results were found. In fact, one of them, THF, seemed to inhibit dimerization reaction. Hence, we have tested an alternative natural peroxidase source obtained from the wastes of a local highly-consumed vegetable and studied their enzymatic activity towards the preparation of biologically active, valuable compounds.

The serine/threonine protein kinase CK2, a tetramer composed of a regulatory dimer (CK2β2) bound to two catalytic subunits CK2α, is a well-established therapeutic target for various pathologies, including cancer and viral infections. Several types of CK2 inhibitors have been developed, including inhibitors that bind to the catalytic ATP-site, bivalent inhibitors that occupy both the CK2α ATP-site and the αD pocket, and inhibitors that target the CK2α/CK2β interface. Interestingly, the bivalent inhibitor AB668 shares a similar chemical structure with the interface inhibitor CCH507.

Lanthanide(III) complexes with two-photon absorbing antennas are attractive for microscopy imaging of live cells because they can be excited in the NIR. We describe the synthesis and luminescence and imaging properties of two Eu complexes, and , with (-carbazolyl)-aryl-alkynyl-picolinamide and (-carbazolyl)-aryl-picolinamide antennas, respectively, conjugated to the TAT cell-penetrating peptides. Contrary to what was previously observed with related Eu complexes with carbazole-based antennas in a mixture of water and organic solvents, these two complexes show very low emission quantum yield (Φ < 0.

DNA structures with the potential to concurrently recruit multiple ligands are promising in pharmaceutical and sensing applications when concentrated in a local environment. Herein, we found that human telomeric G-quadruplex (htG4) structures with a junction can selectively aggregate a natural ligand of tetrahydropalmatine (THP) into AIEgens. The htG4 monomer favors formation of a THP dimer emitting at ∼525 nm.

We identified a 5-fluoro-benzothiazole-containing small molecule, TKB272, through fluorine-scanning of the benzothiazole moiety, which more potently inhibits the enzymatic activity of SARS-CoV-2's main protease (M) and more effectively blocks the infectivity and replication of all SARS-CoV-2 strains examined including Omicron variants such as SARS-CoV-2 and SARS-CoV-2 than two M inhibitors: nirmatrelvir and ensitrelvir. Notably, the administration of ritonavir-boosted nirmatrelvir and ensitrelvir causes drug-drug interactions warranting cautions due to their CYP3A4 inhibition, thereby limiting their clinical utility. When orally administered, TKB272 blocked SARS-CoV-2 replication without ritonavir in B6.

Artemyriantholidimers A-G (1-7), seven undescribed guaiane-type sesquiterpenoid dimers (GSDs), and 27 known compounds (8-34) were isolated from Artemisia myriantha (Asteraceae). Their structures and relative configurations were elucidated based on the comprehensive analyses of UV, IR, MS, NMR data, quantum chemical NMR calculations with DP4+ probability analyses, and the absolute configurations were elucidated by ECD calculations. The undescribed GSDs (1-7) were presumably formed via Diels-Alder reactions, and compounds 5-7 were rare GSDs with α-configuration of H-6'.
