addition/enolate alkylation annulation with a novel ambiphilic trifluoroborate in seven steps. A new class of alkenyl and aryl ambiphilic trifluoroborates were synthesized and showed great compatibility with various functional groups, high yields, and excellent enantio- and diastereoselectivity. A novel benzo-fused cannabinoid analogue and tandem quaternary stereocenter-containing reaction products
New Nucleotide-Competitive Non-Nucleoside Inhibitors of Terminal Deoxynucleotidyl Transferase: Discovery, Characterization, and Crystal Structure in Complex with the Target
Terminal deoxynucletidyl transferase (TdT) is overexpressed in some cancer types, where it might compete with pol μ during the mutagenic repair of double strand breaks (DSBs) through the nonhomologous end joining (NHEJ) pathway. Here we report the discovery and characterization of pyrrolyl and indolyl diketo acids that specifically target TdT and behave as nucleotide-competitive inhibitors. These compounds
