A general protocol for iridium catalyzed direct C−H amidation of cyclic N-sulfonyl ketimines using sulfonyl, acyl and arylazides as nitrogen source is reported herein. The reaction takes place at roomtemperature with acyl and arylazides, while an elevated temperature needed with sulfonylazides to furnish aminated sultams in excellent yields with complete chemo and regioselectivity, thus providing

The introduction of CF3 reporter groups close to the paramagnetic centre in macrocyclic lanthanide(III) complexes allows faster acquisition of 19F magnetic resonance data, and amplifies chemical shift non-equivalence, as exemplified by the definition of ratiometric chemical shift probes for pH and, in principle, enzyme activity.

Phosphoglycerate mutase 1 (PGAM1) is a glycolytic enzyme that dynamically converts 3-phosphoglycerate (3PG) to 2-phosphoglycerate (2PG), which was upregulated to coordinate glycolysis, pentose phosphate pathway (PPP) and serine biosynthesis to promote cancer cell proliferation and tumor growth in a variety of cancers. However, only a few inhibitors of PGAM1 have been reported with poor molecular or
A series of novel bis(arylsulfonyl)dihydroimidazolinones with different aryl substitution patterns were readily synthesized and evaluated for their antitumoractivities. Some of the newly synthesized compounds exhibited cytotoxicity at micromolar range against multiple cancer cell lines, including A549, HepG2, HuCCA-1, and MOLT-3. The most potent analogue contained pentafluorobenzenesulfonyl groups
